48 THIRTY-SECOND REPORT ON THE STATE MUSEUM. 
Petioles of fallen maple leaves. Adirondack Mountains. July. 
This species is closely related to H. gracile and H. fastidiosum, which 
relationship suggests the specific name. It imitates the latter species in its 
habitat, but I have not found it except on the petioles and occasionally the 
midyeins of maple leaves, 
HELOTIUM PALUSTRE 2. sp. 
Cups stipitate, plane or slightly convex, pallid or whitish; stem 3/—6'- 
long, slightly thickened at the base; asci subclavate ; spores oblong, .0004'- 
.0005' long. 
Fallen leaves in wet places. Sandlake. May. 
In the dried specimens the hymenium assumes a dark reddish-brown or 
chestnut color. The stem is long in proportion to the size of the cup. 
HELOTIUM VIBRISSEOIDES 7, sp. (Plate II, figs. 7-9.) 
Cups sessile, 1 —-2” broad, immarginate, externally blackish or blackish- 
green, the disk plane or convex, livid-white or blackish-green; asci very long, 
linear; spores elongated, filiform, very slender, sometimes becoming coiled, 
bursting forth and covering the disk with a whitish webby stratum. 
Decaying sticks lying in water. Sandlake and Catskill Mountains. May 
and July. 
Externally this fungus has the appearance of a Helotium, but the fructifica- 
tion is exactly that of a Vibrissea. It seems to me that it really belongs to 
the genus Vibrissea, but I am prevented from placing it there because in the 
absence of a stem it fails to meet fully the published characters of that genus. 
I am fully persuaded that some of the genera of fungi are imperfectly character- 
ized, and that we cannot have a satisfactory arrangement of our species until 
these defective descriptions are modified or revised. 
PATELLARIA PUSILLA 7%. Sp. 
Cups sessile, small, .014’—.028’ broad, slightly margined, the disk plane or 
convex when moist, slightly concave when dry, black; asci clavate ; spores 
crowded or biseriate, lanceolate or subclavate, 6—8-nucleate, .00065’/—.0008/ 
long, .0001'-.00012/ broad ; paraphyses numerous, filiform, not thickened at 
the apex. 
Decaying beech wood. Catskill Mountains. July. 
The spores in shape are similar to those of P. atrata. They are extremely 
narrow and probably become 5—7-septate when fully mature. 
a 
DERMATEA MINUTA 7”. Sp. 
Cups minute, .009'-.017’ broad, numerous, scattered or sometimes two or 
three crowded together, attached by a small point, grayish, the disk subo- 
chraceous, margin obsolete, disk plane or convex; asci oblong-clavate ; spores 
crowded, oblong-elliptical, .0008/-.001’ long, colorless, simple ; paraphyses 
filiform, thickened at the apex. 
: itp stems of hobble-bush, Viburnwm lantanoides. Catskill Mountains. 
July. 
This is the smallest species of Dermatea known to me.
