22 Thirty-third Axnual Report of the 



Polyporus chioneus, Fr. Decaying wood of frondose trees. Ve- 

 rona. Aug. 



Polyporus floccosus, Fr. Decaying wood. Verona. Aug. 



Stereum neglectum, n. sp. Pileus effuso-reflexed, thin, coriaceous, 

 ofteu laterally confluent, strigose-hairy, concentrically sulcate, gray- 

 ish or yellowish-gray ; hymenium pallid, becoming purplish, minutely 

 setulose, the setae short, colorless, rough, stout, .002 in. to .003 in. long ; 

 spores subelliptical, .0005 in. long, .0003 in. broad. Dead trunks 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 setae. A genus Peniopliora 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, n. 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, 

 colorless, .0004 in. to .0005 in. long, about .00016 in. broad. Culms and 

 leaves of carices. Verona. Aug. 



Olavaria miniata, Berk. Damp ground. Burnt hills, Saratoga 

 county. July. 



Olavaria pyx idata, Pers. Oneida. H. A. Warne. Buffalo. Clinton. 

 Savannah. Ang. 



Hymenula hysterioides, n. sp. Minute, oblong or elliptical, plane or 

 slightly convex, amber color, when dry contracted, hysteriiform, black- 

 ish ; 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. R. 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, n. 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 persistently 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
