The Parasitic Fungi of New Jersey

PARASITIC FUNGI OF NEW JFKSEY
Introduction

This work is the gradual outgrowth of a plan devised to increase
the knowledge pertaining to the parasitic fungi of the state of New
Jersey. In developing this plan the writer drew freely from such
works as, Catalogue of Plants Found in New Jersey by Dr. N. L.
Britton (in the Geological Survey of Neiv Jersey, Report of the
State Geologist, 1889, v. 2, pt. 1, p. 25-642), reports and bulle-
tins of the New Jersey Agricultural Experiment Station, North
American Pyrenomycetes by Ellis and Everhart, North American
Flora, Mycologia, Bulletin of the Torrey Botanical Club, Grevillea,
Proceedings of the Philadelphia Academy of Natural Science, and
publications of the United States Department of Agriculture.

The writer had ample opportunity during the summers of 1912 to
1917, inclusive, to collect and preserve parasitic fungi in the state
of New Jersey. This material and "fungi exsiccati" deposited in
the herbaria of the New Jersey Agricultural Experiment Station
and the New York Botanical Garden afforded the writer excellent
opportunities to study the fungous parasites.

The plan formulated at first was to list all fungous parasites
recorded for the state of New Jersey and supplement diis list with
their descriptions and drawings of specimens illustrating the respec-
tive genera. This plan, however, was abandoned because many
specimens collected and recorded by the pioneer botanists had been
incorrectly determined. It was finally decided to publish descrip-
tions and illustrations only of those species which had been studied
in the laboratory.

Whenever possible, specimens collected in New Jersey were
studied. When no New Jersey material was available specimens
from neighboring states were examined.

To gain a broader view of the nature of fungous parasites, cul-
tures were made in many cases on agar media or on the natural host.
Whenever possible, therefore, spore measurements and the growth
on nutrient media were compared with those displayed by the para-

(3)

site on its natural host. In case the original descriptions were
meager, inaccurate or obsolete, the descriptions were amplified.
Credit is given at the proper place when tlie description is taken
verbatim from a monograph, etc.

All the drawings are original and were made by the author. The
same microscope and camera lucida were used and therefore all
the fungi were drawn on a imiform scale. The magnification in
every instance is appended to the description.

To avoid confusion a generic name of long standing was used.
A reference at the proper place was made to the recent terminolog)'.

The writer wishes to thank the members of the staff of the New
York Botanical Garden for tlie permission to examine specimens in
the Crj-ptoganiic herbarium, for the library facilities and for many
helpful suggestions. The writer is also under great indebtedness to
Prof. J. C. Arthur, who not only determined the rusts but freely
oitered advice and criticised that portion devoted to the Uredinales,
to Dr. G. P. Clinton for determining the smuts, and to Prof. F. C.
Stewart, Geneva, N. Y., Doctors R. A. Harper, W. A. Murrill, F. J.
Seaver, A. B. Stout, Donald Reddick, V. B. Stewart, C. L. Shear,
J. J. Davis and F. D. Fromme for helpful suggestions.

The writer is also under great indebtedness to Prof. Melville
Thurston Cook, head of the Department of Plant Pathology of the
New Jersey Agricultural Experiment Station, who directed the
work, for his encouragement, advice, helpful suggestions and cooper-
ation in preparing the descriptions, for the arrangement of the
plates and for reading the proof.

flower and related plants. Causes enlargement of the infected parts
which are commonly known as "club root" or "finger and toe" dis-
ease. The organism lives within the parenchyma cells and stimulates

and cortex become thickened; the sclerenchyma cells suppressed,
xylem reduced, and the phloem increased.

section of diseased root showing organisms within certain cells, 2/3. 4. Plas-
modium in cells, 1/6. 5. Plasmodium in 4 distinct divisions showing multi-
nuclei, 1/6. 6. First stage in the formation of spores, 1/6. 7. Second stage

14. Dead fly covered with the fungus. 15. The immature sporangia, 2/3.
16. Two stages in formation of the spores, 1/6. 17. Emerging of the zoo-

Taphrina deformans (Pel.) Tul. — On the leaves, young fruit,
twigs of the peach. Causes leaves to curl, frequently becoming
pink or yellowish, and causes blisters on twigs and fruit. Asci are
formed just below the cuticle on the lower surface. They are cylin-
drical to slightly clavate, the ends rounded or truncate, 25-40 x
8-11 fi; the stalk cells, 6-8 x 6-10 /x; frequently tapering towards
the base ; 4-8 asco-spores are sub-globose or oval and measure 3-5 x
4-6 /x. They frequently go through a process of budding either
before or after escaping, and produce conidia.

Taphrina pruni (Fckl.) Tul.— On plums and cherries. Causes
the "plum pockets," a bladdery-like growth of the fruits, and also
attacks very young shoots. The asci are formed early in great num-
bers, breaking through and almost destroying the cuticle. Asci
long and cylindrical, 30-60 x 8-15 fx; spores 8, globose, 3.5-5 fx.

ScLEROTiNiA FRUCTIGENA (Pers.) Schr. — On the fruit, flowers,
leaves and stems of peach, plum and cherry, and other drupaceous
fruits. Causes a rotting of the fruit; dying of blossoms, young
twigs and young shoots early in the season; and the formation of
cankers on the twigs and smaller branches. The conidial stage
{Monilia friictigcna Pers., page 114) is most conspicuous on fruits,
many of which cling to the tree as mummies. The conidiophores
and conidia in mass appear as a dense gray, bro\vnish or ochraceous
mold-like growth. The conidia measure about 20.9 x 12.1 /a. The
apotliecia are rare in Xew Jersey. They are produced from the
sclerotia on the fallen mummied fruits and measure about 0.5-3 cm.
in height; the stem is dark brown and the disk somewhat lighter
and measures about 5-8 or occasionally as much as 15 mm. in diame-
ter; asci 125-215 x 7-10 n; ascospores ellipsoidal and 10-15 x 5-8 /i.

defined; varying from mere specks to about 1.5 to 2 mm. in diame-
ter. The spots appear early in the season but the apothecia are
rather slow in forming and are usually most abundant in the fall.
The apothecia are ver}- small, amber or black shiny elevations. The
asci are elongated and contain 8 spores ; the paraphyses are filiform
to clavate; the spores are hyaline, non-septate, elliptical and 8-11 x
4-6 /Lt.
