Peck: New Specits oF Funai 97 
Bolbitius Glatfelteri 
Pileus thin, conical or subcampanulate, soon expanding with 
the margin curving upwards, sometimes umbonate, glabrous, very 
viscid, widely striate on the margin, white, yellowish or tawny in 
the center ; lamellae close, rather narrow, subventricose, free, pal- 
lid, becoming ferruginous and pulverulent; stem equal or slightly 
tapering upward, hollow, slightly striate above, slightly squamu- 
lose or furfuraceous when young, becoming glabrous and shin- 
ing, pure white ; spores 12~16 4 long, 8-10 ut broad. 
Pileus 2-3 cm. broad; stem 5—10 cm. long, 4—5 mm. thick. 
Gregarious or cespitose on rotted manure. Missouri and Illi- 
nois. April and May. N. M. Glatfelter. The species is appar- 
ently related to B. sordidus Lloyd, from which it may be separated 
by its larger spores and more narrow lamellae. 
Fomes albogriseus 
Pileus elongated ungulate, externally hard, lignose, concentri- 
cally sulcate, azonate, the younger parts of the crust isabelline or 
pale gray, suffused with a slightly detersible pruinosity, the 
older parts becoming uneven, rimose and blackish gray, inner sub- 
stance somewhat soft, friable, whitish; pores minute, obscurely 
stratose, white within, their mouths pallid or isabelline. 
Pileus 7~35 cm. long, 10-25 cm. broad, 5-15 cm. thick. 
Trunks of tamarack and white pine. Kent county, Michigan. 
July. B.O. Longyear. In size and shape this fungus resembles 
elongated forms of F. fomentarius, and it does not differ greatly in 
color from faded specimens of that species. In the character of 
its annual increments it resembles Polyporus juniperinus Schrenk. 
Each new increment is a little smaller at its base than the adjacent 
part of the one preceding it. Consequently the mouths of the 
marginal pores of the older increments can be seen in the furrows 
that separate the increments. Polyporus officinalis is said to in- 
habit the larch, but its pileus is described as variegated with 
yellowish and fuscous zones and as having a farinaceous odor, a 
bitter taste and short pores, characters not shown by our fungus. 
Hydnum conigenum 
Pileus coriaceous, 1-2 cm. broad, obconic, nearly plane above, 
even, minutely downy, grayish orange or yellowish orange, some-
