HYALOPSORA.

The genus should follow Milesia, and becomes no. 10. In the description of the
genus, the key to species, and the descriptions of the four species which follow, the
terms “‘ aecia’’ and “ aeciospores ”’ should be understood as applying to the large-sized
form of uredinia and urediniospores.

Replace the first paragraph describing the genus by:

Cycle of development includes pyenia, aecia, two forms of uredinia, and telia, with
distinct alternating phases; heteroecious. Pycnia, aecia and uredinia subepidermal,
telia within epidermal cells.

Pyenia depressed-conoidal or lenticular in section, without ostiolar filaments.

pointed urediniospores.

Replace the first paragraph by:

Cycle of development includes pycnia, aecia, two forms of uredinia, and telia, with
distinct alternating phases; heteroecious. Pycnia subcuticular, aecia and uredinia
subepidermal, telia rudimentary, the teliospores solitary, scattered in the mesophyll,
segregated beneath the epidermis, or rarely within the epidermal cells.

Pycnia flattened-hemispheric, rising little above the leaf-surface, and extending between
the cells and depressing the tissues beneath, often appearing subepidermal, without
ostiolar filaments.

Aecia erumpent, deep-seated, definite, colorless. Peridium cylindric, with medium-

O. Pycnia unknown, probably not formed.

Ill. Telia hypophyllous and caulicolous, systemic from a perennial mycelium, following
the veins or covering large areas, bullate, round or elliptic, large, 0.5-1 mm. broad by
0.5-1.5 mm. long, at first orange-yellow, becoming pale-yellow, soon dehiscent by a
central opening, pulverulent; peridium colorless, evanescent; peridial cells oblong,
slightly larger than the teliospores, the outer wall transversely striate, 5-7 uw thick,
smooth, the inner wall thinner, 1-3 u, coarsely verrucose; teliospores angularly globoid
or oblong, 16-26 by 18-304; wall pale-yellow, moderately thin, 1-2», closely and
rather prominently verrucose.

The habit, general structure, and hosts indicate that this species is correlated with the
autoecious Allodus graminella (Speg.) Arth. and the heteroecious Allodus interveniens
(Peck) Bethel, although some difference exists in the thickness of the walls of correspond-
ing spores and peridial cells in the three species. They have doubtless been derived from
a common origin, together with Micropuccinia Sherardiana (Korn.) Arth. & Jackson.
