22 THIRTY-THIRD ANNUAL REPORT OF THE 
Polyporus chioneus, /r. Decaying wood of frondose trees. Ve- 
rona. Aug. 
Polyporus floccosus, Fr. Decaying wood. Verona. Aug. 
Stereum neglectum, m. sp. Pileus effuso-reflexed, thin, coriacvous, 
often laterally confluent, strigose-hairy, concentrically sulcate, grav- 
ish or yellowish-gray ; hymenium pallid, becoming purplish, minutely 
setulose, the seta short, colorless, rough, stout, 002 in. to .003 in. long; 
spores subelliptical, 0005 in, long, 0003 in. broad. Dead tranks and 
branches of elm trees. Verona. Aug. This fungus has the general 
appearance of such species as S. purpureum, S. vorticosum and S. hir- 
sutum, from all of which it may be distinguished by its peculiar hy- 
menium which, to the naked eye, has a pruinose appearance by reason 
of the presence of the minute colorless sete. A genus Peniophora has 
been proposed for such species, and if accepted our plant will belong to — 
it. The hymenium is sometimes rendered uneven by the confluence of 
several individuals. 
Cyphella caricina, ». sp. Cups .5 line to .1 line broad, membrana- 
ceous, sessile,, white, externally minutely webby-hairy ; hymenium 
smooth, in large specimens uneven; spores lanceolate or subclavate, 
polarless, 0004 in. to .0005 in. long, about .00016 in. broad. Culms and 
leaves of carices. Verona. Aug.

Hymenula hysterioides, ». sp. Minute, oblong or elliptical, plane or 
slightly convex, amber color, when dry contracted, hysteriiform, black- 
ish 3 spores numerous, oblong, hyaline, .0003 in. to .00035 in. long. 
Wood of red osier, Cornus stolonifera. Center. May. When dry it 
looks like some minute Hysterium, but when moist it expands and 
reveals the pallid or amber-colored hymenium. 
Simblum rubescens.- Ger. in litt. Astoria, Long Island. Sept. 
W. k. Gerard. 'This is the only representative of the genus yet found 
in this country. It differs from all the other species in its pinkish-red 
color. One specimen was found in which the pileus was supported by 
two distinct stems arising from one volva. 
Physarum mirabile, 2. sp. Sporangium hemispherical or depressed, 
nearly plane above, pervious, minutely rough or squamulose, 
yellow or tawny, rupturing irregularly, the basal part adherent to the 
top of the stem; capillitium composed of slender pale or yellowish 
filaments and yellow, knot-like thickenings of two kinds, one minute 
and subglobose, the other elongated, pointed or spine-like, conspicuous 
and persis stently attached to the inner wall of the sporangium ; stem 
equal or slightly tapering upward, reddish-brown, penetrating quite 
through the sporangium and forming a hollow, persistent, yellow co- 
lumella open at the top; spores globose, smooth, blackish-brown, 
.0003 in. in diameter. 
Decaying wood and bark. Verona. Aug. This species is remark- 
able for the peculiar spine-like thickenings of the capillitium and for 
the singular elongated hollow columella. In a vertical section of the 
unruptured sporangium the former may be seen extending from the 
walls of the sporangium to the columella. The latter is yellow or
