INTRODUCTION.

The Agaricaceae constitute a rather large family of the
Basidiomycetae and are commonly known as the “gill fungi.”
The family is characterized by having the spores borne on club-
shaped basidia arranged in a definite layer known as_ the
hymenium, which covers a number of radiating plates, the
lamellae or “gills”, suspended from the lower surface of the
pileus, or cap. <A Stipe, or stem, is usually present, but may be
wanting.

Many of the species are edible, and some are considered
a great delicacy. Others are poisonous, and may cause serious
illness or even death. A few are parasitic upon certain higher
plants, notably upon the roots or trunks of trees, when they
may cause extensive injury to the timber. Many are beautifully
colored, red, yellow, purple, brown, white, etc., or quite large,
or otherwise striking in appearance. For these reasons ani
others these plants are interesting objects of study.

The present paper is essentially a preliminary report on
the Agaricaceae of Ohio and consists of keys to the genera and
species reported as occurring within the state. A glossary of
descriptive terms and a bibliography of the literature pertaining
to the Ohio species and other works, which will be found help-
ful to the student, are included.

The list of species has been made up from the works (see
bibliography) of Lea, Morgan, Hard, Lloyd, Peck, Berkeley,
Kellerman and Montagne. Besides the species thus published,
the list has been augmented by reference to specimens in the
herbarium of the New York Botanical Garden, the herbarium
of the state botanist of New York, the herbarium of the Ohto
State University and by the collections of the writer.

Thomas G. Lea collected in southwestern Ohio, 1834-1844,
and sent his specimens to Rev. M. J. Berkeley, in England, who
described a number of new species from them. Others were
referred to existing species. Morgan, a number of years later

462

The Agaricaceae of Ohio. 463

(1878-1907), collected in the same region. He greatly extended
[.ea’s list (although he did not recognize all the species pre-
viously reported by Lea) and described a number of new species.
W. S. Sullivant, an eminent bryologist of Columbus, sent a num-
ber of collections to Montagne in Paris during the early fifties,
some of them with drawings by Mr. Sullivant or by Mr. Robin-
son who worked with him. Montagne described fifty-five new
species from these specimens. It seems remarkable that none
of these species have been certainly recognized since. Most of
them are probably to be referred to other species, or at least
are now recognized by other names.

Peck has described species based on specimens sent to him
by Ohio collectors, Morgan, Lloyd, Kellerman and others. Some
of Peck’s New York species have also been found in Ohio, His
types are all, or nearly all, preserved in the state herbarium at
Albany. Hard collected in several parts of the state and pub-
lished his results in a well illustrated book. Professor Atkin-
son, of Cornell University, also described several species from
material sent to him by Kellerman and Hard.

The list at present includes approximately five hundred and
forty (540) species. Some of these are of doubtful determina-
tion. In many cases the collections were not preserved, and it
is impossible at this date to confirm or correct the determination.
The type specimens of Montagne have not been available to the
writer for study, and, except for a few species of Marasmius,
\Morgan’s types were not preserved. Whether these will all
prove to be valid species must be left for future study to deter-
mine.

Moreover, the list is not claimed to be complete. There are
doubtless many species occurring in the state which have not
yet been reported, for some sections have scarcely been worked
over at all. Before it is possible to have a fairly complete and
reasonably accurate state list, there must be a large number of
specimens from different parts of the state assembled in acces-
sible herbaria, preferably, the state herbarium. If notes on the
fresh plants accompany each specimen, the collection will have
much greater value.

464 Proceedings of the Ohio State Academy of Science.

In preparing the kevs, the most apparent characters possible
have been employed. The aim has Leen to produce accurate and
usable keys, rather than to exhibit relationships of species. Some
of the keys have been tested by use by mycology students at
Miami University for several years and at the Ohio State Uni-
versity during the present year. Most of them have been re-
vised several times as suggested by use.

The work is based largely on published descriptions, and
in some cases altogether. These are sometimes so brief or so
lacking in precise detail that it has been difficult to find reliable
and well-marked characters upon which to separate species.
This is especially true of species founded wholly upon dried
specimens.

Notwithstanding such errors, misconceptions and incorrect
conclusions as doubtless occur, it is believed that the paper will
prove helpful to students, amateur mycologists and others in
the determination of Ohio Agarics. It is offered as a summary
of our present knowledge of the Ohio plants, and is to be re-
garded as only a preliminary study.

It is not within the scope of this paper to discuss the species
in detail, so that many points of interest and of some impor-
tance must necessarily be omitted. With each species included,
however, a list of references to the most available and useful
works is given. One or more of these should always be con-
sulted before reaching a decision as to the determination of
any plant.

The matter of the classification and nomenclature of the
Agaricaceae is still in an unsettled condition. It has seemed best
in most instances to follow the arrangement given by Saccardo
in his Sylloge Fungorum for two reasons: It is not the pur-
pose to present a critical study of the nomenclature of the family,
and most of the available works on this group will be found to
follow a similar system.

The writer wishes here to acknowledge his many obligations
to Dr. Bruce Fink under whose direction the work was under-
taken. He is also indebted to Dr. W. A. Murrill for the privilege
of examining specimens in the herbarium of the New York

Botanical Garden; to C. H. Peck for the determination of a
number of species, and for the privilege of studying type speci-
mens in the herbarium of the state botanist at Albany; to Mr.
S. H. Burnham, his assistant; to Miss Gertrude S. Burlingham,
of Brooklyn, for aid in the determination of species of Russula
and Lactaria; to Mr. C. G. Lloyd for library privileges in the
Lloyd Library at Cincinnati; to Mr. William Holden, librarian,
for many courtesies while consulting literature; to Professor
T. H. Macbride for the loan of the specimens of Marasmius in
the Morgan collection, now at Iowa City, Iowa; to Mrs. Laura
Vaile Morgan for the loan of Mr. Morgan’s manuscript; and
to others in various ways.

DouBTtFuL SPECIES.

A. flavo-rubens B. & M., described from specimens collected
at Columbus by Sullivant, has not been since reported. As sug-
gested by Lloyd, it is doubtless a form of A. muscaria. S. 17.

A. daucipes B. & M., also described from Sullivant’s ma-
terial, is placed in Amanitopsis by Saccardo, and in Lepiota by
Morgan. It is probably a variety of A. solitaria. Not reported
since Sullivant’s time. S. 26.

A. polypyramis B. & C. is placed in Lepiota by Morgan who
reports it from Preston, O. As stated by Morgan and sug-
gested by Atkinson, it is probably a form of A. solitaria. S. 18.

Morgan regards A. radicata as a form of A. solitaria but
placesat in=epiotas” J. Me 13-12:

A. verna is regarded by most writers as a variety of A.
phalloides. A. virosa is also so regarded by some.

NOTES.

L. porrigens Viv., listed by Morgan (Jour. Myc. 13:6) is
probably to be considered a white form of L. procera.

I.. lutea. Bolt., listed by Morgan (Jour. Myc. 13:4), is
usually regarded as a yellow form of L. cepaestipes.

L. rufipes Morg. Jour. Myc. 12:156, is probably not specifi-
cally distinct from L. mesomorpha Bull.

The occurrence of L. farinosa Peck in Ohio is doubtful.
Peck separated it from L. cepaestipes on account of the even
margin and the larger. spores (Report 43, p. 35), Morgan (Jour.
Myc. 13:1, 3) in reporting the former, says that the chief dif-
ference is in the color of the pileus. He gives the same spore
measurements for both species.

Several writers state that L. americana is L. badhami Bb. &
Bie oft urope.

The Agaricaceae of Ohio. 4y1

The occurrence of L. pelidna B. & M., described from
Sullivant’s material, is doubtful. It is said to have a greenish-
livid, rugose pileus, a solid, bulbous stipe and to grow on fallen
logs, oF 67.

Fries (Hym. Eur. 31) regarded L. acutesquamosa as a
variety of L. Friesii Lasch, from which it differs in having the
scales of the pileus erect and the lamellae simple. In this country
the plants are usually known as L. acutesquamosa, Morgan lists
the species as L. aspera Pers. His plants referred to L. hemisclera
B. & C. and to L. asperula Atk. were probably only forms of L.
acutesquamosa,

LL. glischra Morg. Jour. Myc. 12:203 is based on plants
referred to L. oblita Peck in the Mycologic Flora (p. 64).

The plants referred by Morgan to L. felinoides Peck should
probably be referred to L. rubrotincta .

I. coerulescens Peck = L. virescens (Speg.) Morg.

L. rufescens Morg. Jour. Myc. 12:246, is based on plants
which he had previously reported as L. fuscosquamea Peck
(Mycologic Flora, p. 62).

L. naucinoides Peck is said by its author to differ from
L. naucina Fr. principally in having the spores subelliptic, while
those of the latter were said to be globose. The two species are
probably not distinct, for the spores of the American plant, at
least, are variable in shape.

Saceardo publishes C. subditopoda Peck as “umbonate.”’
Peck described it as umbilicate and says he separated it from C.
ditopoda Fr. on account of the paler lamellae, striate margin and
longer spores. C. ditopoda, however, is not umbilicate.

C. pruinosa Lasch was first reported by Lea, but does not
seem to have been found since. None of Montagne’s species
have been identified since their publication.

According to Bresadola C. monadelpha is the same as C.
tabescens (Scop.) Bres. of Europe (Lloyd Myc. Notes 1:54).

Lentinus caespitosus Berk. and Pleurotus caespitosus B. &

NOTES.

C, pilularia, C. xanthopila, C. physcopodia and C. tagetes
were described from specimens sent to Montagne by Sullivant
and have not been recognized since.

Morgan’s description of C. estensis is rather meager. It 1s
probably a form of C. dryophila or perhaps is identical with C.
strictipes.

The plants referred by Hard (p. 108) to C. ingrata
Schum. should probably be considered a form of C. confluens.
According to Berkeley (Outlines of British Fungology, p. 117),
the principal difference between the two species is that in the
former the lamellae more nearly approach the stipe.

Some writers believe that C. tenuipes and C. amabilipes are
identical. Schweinitz described the former as having a stipe
15-30 cm. long, pileus depressed and subumbonate, plants grow-
ing among decaying leaves. The Ohio plants grow on decayed
wood, the pileus is convex-expanded, and the stipe is variable in
length, but seldom more than 8-10 cm. long. Peck’s description
of C. amabilipes fits our plants more closely, and unless we as-
sume that Schweinitz had very exceptional specimens, they
should be known by Peck’s name. Lloyd says the pileus is
slightly viscid, but we have never found it so. (Myc. Notes

NOTES,

M. lilacina Mont., described from Sullivant’s material (S.
257), is a doubtful Mycena. The pileus is said to be lilac-col-
ored and umbilicate; the lamellae remote (when dry) and rosy-
ochraceous. The plants may possibly have been M. pura, the
abnormal character appearing in drying.

Neither the above nor M. cymbalifera nor M. conferrumi-
nata have been recognized since described.

M. vitrea and M. vulgaris have not been definitely reported
from Ohio but probably occur here and so are included.

NOTES.

O. alboflava is closely related to O. chrysophylla and 1s prob-
ably a variety of the latter." The plants figured by Hard (p. 135,
f. 100) as O. alboflava agree more closely with the description of
©. chrysophylla.

garded by its author as a variety of O. chrysophylla.

scribed from Sullivant’s material, do not seem to agree with
the characters of the genus. The former is described as having
the lamellae adnexed and decurrent by a tooth; the latter, as hav-
ing the edge of the lamellae obtuse. In Omphalia the lamellae are
truly decurrent and the edge acute. (See S. 318 and S. 333.)

NOTEs.

P. nidulans Pers. is now usually placed in the genus Claud-
opus on account of its salmon-colored or pink spores. P. sapidus,
which has pale lilac spores, is usually regarded as a Pleurotus
because of its obvious relations with some species of that genus.

Plants formerly referred to P. serotinoides Peck and P.
abscondens Peck, ana so listed by Hard, are now regarded by
Peck as varieties of P. serotinus and P. lignatilis respectively.

Kellerman and Werner (p. 305) include P. acerinus in the
list of Ohio plants. This seems to be the only reference to this
species in Ohio literature.

Plants referred by Morgan to P. niger Schw. were probably
P. applicatus, which is a rather common species in southwestern
Ohio.

The plants referred to P. circinatus by Hard were probably
P. lignatilis. He says it may be known by the white gills. The
lamellae of P. lignatilis are white.

The occurrence of P. pinsitus in Ohio is rather doubtful.

P. caespitosus B. & C. was first published as a Lentinus,
then as a Pleurotus. It is probably the plant now known as
Clitocybe monadelpha Morg.

516 Proceedings of the Ohio State Academy of Science.

P. corticatus is very close to P. dryinus Pers. It should
probably be regarded as a variety of the latter as Atkinson does.

NOTES.

The nomenclature in the above key is that employed by Miss
Burlingham in her monograph of the genus in the North Anter-
ican Flora. The genus is commonly known as Lactarius, which
Miss Burlingham regards as merely a variation in spelling. L.
lactiflua is commonly known as L. volema, and L. rusticana is
usually published as L. pyrogala. In these cases both names are
given.

L. distans Peck, reported by Morgan and Hard, is now re-
garded by Peck as a synonym for L. hygrophoroides. L. sordida
Peck is a synonym for L. turpis.

L. vieta Fr., L. caleeola Berk. and L. zonaria (Bull.) Fr.
were reported by Lea and included in Morgan’s list. The first
has not been otherwise reported from North America. L. cal-
ceola was probably an abnormal form of L. hygrophoroides. Of
the three only L. zonaria is included in the key and its occur-
rence in Ohio is doubtful.

L. torminosa has not been reported for Ohio but its range
is such as to indicate that it will likely be found here.

NOTES.

R. cyanoxantha, R. integra, R. roseipes, R. adusta, R. pur-
purina, R. fragilis and R. nigricans have not been definitely re-
ported from Ohio as yet. Their range, however, makes it likely
that they occur here and they are included in the key for con-
venience in determination.

Morgan reports R. lutea Fr. but from his notes it is evident
that his plants should be referred to R. flavida which is rather
frequent in southwestern Ohio during some seasons. R. lutea
has not been otherwise reported and is omitted.

Most American plants formerly referred to R. furcata are
now more properly referred to R. variata. It is uncertain at
present whether the true R. furcata occurs in Ohio.

NOTES.

Murrill regards the name Cantharellus as a variant in
spelling of Chanterel and discusses the genus under the latter
name (N. Am. Flora 9*:167). He describes C. umbonatus, C.
aurantiacus and C. cibarius respectively as Chanterel muscoides
(Wulf.) Murrill, Chanterel alectorolophoides (Schaeff.) Mur-
rill, and Chanterel Chanterellus (L.) Murrill.

Plants referred by Hard to C. brevipes Peck were prob-
ably young specimens of C. floccosus.

Fries, followed by Saccardo, placed C. cinnabarinus in
the genus Hygrophorus. American writers regard this species
as a good Cantharellus.

NOTES.

Remarkably cespitose plants referred to this genus by the
student should usually be looked for in the genus Collybia. Ohio
plants usually known as Collybia lachnophylla are called Maras-
mius cohaerens (Fr.) Bres. by some writers.

Montagne’s species have not been recognized by collectors
since their publication,

The plants reported by Morgan in the Mycologic Flora as
M. fusco-purpureus Pers, were later referred to M. semihirtipes.

M. elongatipes was first published as M. longipes. The
latter name was preoccupied.

M. siccus, M. bellipes, M. campanulatus and several other
species not reported from Ohio are very closely related. The
pileus of M. siccus is described as “roseo-pallido”; that of M.
campanulatus as ochraceous-red. A plant with the pileus bright
ochraceous is frequent in Ohio. Another with the pileus pinkish
to purplish also occurs. In very young plants the stipe is of
the same color, but becomes blackish-brown as it matures, be-
ginning at the base, the apex remaining purplish for some time.
Morgan has described this plant as M. bellipes. Even in dried
specimens (at least if not too old) the plants can be readily
distinguished. In this paper the plants with ochraceous pileus
are regarded as M. campanulatus, while those with pinkish or
purplish pileus are regarded as M. siccus with M. bellipes as
a synonym.

NOTES.

Morgan lists L. lecomtei Fr. and L. strigosus Fr. He later
decided that the plants so referred were species of Panus (P.
rudis Fr.),

L. caespitosus Berk., reported by Lea and Morgan is not a
Lentinus. Pleurotus caespitosus B. & C. is another name for the
same plants. Lloyd believes it is the plant now known as Clito-
cybe monadelpha Morg. and the description bears out the opinion,

Peck separated L. spretus from L. lepideus because the
lamellae are not sinuate and the spores are smaller. A collection
was made at Oxford in 1910.

The Agaricaceae of Ohio. 541

L. sullivantii Mont. is probably the same as Clitocybe illu-
dens Schw. L. robinsonii Mont. is certainly not a Lentinus.
The pileus is said to be tubular at first, then cubshaped, the
lamellae are close, linear, long-decurrent. Probably a Canthar-
ellus.

L. curtisii is L. omphalodes B. & C., not L. omphalodes Fr.

L. ursinus and L. vulpinus have doubtless been confused in
America. Peck describes the former as being sometimes costate-
corrugate. This character is, in Europe, ascribed to L. vulpinus
only.

With the meager description of L. pelliculosus it is difficult
to separate it from L. ursinus. It may be only a more hairy
form of that species — at least the Ohio plants referred to it.

Lentodium squamulosum Morg. is often regarded as an
abnormal form of L. tigrinus. It may be recognized by the
mycelium or compact tomentum which grows over the hyme-
nium sometimes obliterating the lamellae. Peck says that both
forms are sometimes found growing on the same stump (M. B.
I31:44).

NOTES.

Berkeley’s description of P. angustatus agrees well with the
plant we know as Pleurotus petaloides Fr. Berkeley says: “Lea
describes it as tough when fresh, and it is therefore placed in the
genus Panus.”’

The plants now known as P. rudis have been reported also
as Lentinus strigosus Fr., and Lentinus lecomtei Fr.

Neither P. robinsonii nor P. sullivantii have been identified
since Sullivant’s time.

in the Polyporaceae. He places the last two species in the genus
Gloeophyllum under the names G. hirsutum (Schaeff.) Murrill
and G. trabeum (Pers.) Murrill. The latter was reported from
Ohio as L. vialis Peck.

NOTES.

I. auricoma Batsch, listed by Lea, is regarded by Fries as
a variety of I. descissa. Morgan, who worked in the same region
as Lea, did not collect it. It is possible that Lea’s plants were
incorrectly determined. The species is omitted from the list.

It is worthy of note here that Peck enumerates 39 species
for the state of New York. Of the 9 species reported from Ohio
only 5 occur in Peck’s list. It is remarkable that such a dis-
paritv should occur in states no more widely separated. It is
probable, however, that further study of Ohio plants will add
a number of species to the Ohio list.

NOTES.

Plants collected by W. A. Kellerman were determined by
A. P. Morgan as H. repandum which is given by Fries and Sac-
cardo as a variety of H. sinapizans. Kellerman’s photograph
(Mycological Bulletin 5: 364) shows the stipe to be stuffed and
hollow. In the European plant the stipe is said to be somewhat
solid.

H. glutinosum and H. crustiliniforme have not been definitely
reported for Ohio but probably occur here. They are included
in the key for convenience.

The Agaricaceae of Ohio. 558

H. latericolor Mont. (S. 803), described from Sullivant’s
material, is probably Hypholoma sublateritium. The color of
the pileus, habitat, season and other characters point to this con-
clusion. H. erysibodes Mont. (S. 795) and H. pyrrholepidum
Mont. (S. 798) are doubtless species of Inocybe.

F. anepsia Mont. (S. 812), was described from Sullivant’s
material. The pileus is said to be reddish-cinnamon; lamellae
distant, adnate-decurrent, and stipe fistulous.

F. flavida has not been reported for Ohio but probably occurs.

F. fusus was collected by Hard at Chillicothe; F. betulina
at Wooster by Van Hook; F. magna at Cleveland by Beardslee,
and F. lubrica at Wooster by Selby. The first three are in the
herbarium of the state botanist at Albany, and the last at the
N. Y. Bot. Garden in New York City.

has a glutinous universal veil, while this species is never glutin-
ous. Flammula, Phylloporus, and Boletinus have each been pro-
posed as the proper genus for it. P. flavidus Berk. (S. 987; M.

NOTES.

A. arvensis and A. silvicola are sometimes regarded as varie-
ties of A. campester.

A brown variety of A. campester occurs but is not common.
This species is reported as usually occurring from August to
October while A. rodmani is said to occur in May and June.

A. xylogenus Mont. (S. toro), described from Sullivant’s
material is not an Agaricus in the present limitation of the term.
It is probably a yellow form of Lepiota cepaestipes. A.
foederatus B. & M. (S. 1003), also described from Sullivant’s
material, is said to have the lamellae affixed and the spores brown.
It is, therefore, either a Pholiota or a Stropharia. Morgan refers
it to the latter genus.

A. fabaceus Berk. (S. 994; M. 111), described from Lea’s
material, is reported common by Morgan, while Lloyd says it has
not been recognized in the last fifty years. The pileus was de-
scribed as being viscid.

A. abruptibulbus is described as white, becoming yellowish in
drying. Plants collected at Oxford and referred by the writer
to this species (Ohio Nat. 10: 178) were tawny even when young
but had the bulbous stipe of the above species. Plants collected
at Columbus in September, 1910, are similar in every respect
except that the stipe is not distinctly bulbous. These have been
referred to A. silvaticus which European writers describe as
brown or tawny. The Oxford plants are for the present re-
garded as a bulbous form of A. silvaticus.

NOTES.

C. fimetarius and C. ephemerus have not been definitely re-
ported from Ohio.

C. insignis is said to resemble C. atramentarius and to differ
from it in the roughened spores (P. R. 26:60). It may be only
a variety.

C. radians in Europe is said to occur on moist plaster walls.
The only reference to it in Ohio gives it as occurring on trunks
of trees (Myc. Notes 1:145). It is probably the same plant re-
terred by Lea and Morgan to C. fuscescens.

A specimen labeled C. angulatus and collected by Lloyd at
Cincinnati is in the state herbarium at Albany.

C. berkleyi and C. stenophyllus, described from Sullivant’s
material by Montagne, are omitted (S. 1094, S. 1095).
