Polyscytalum flavum sp. nov. 2 
Effused, floccose, white at first, then yellow to sulphur-yellow ; 
mycelium scanty ; sporophores scarcely differing from the mycel- 
ium ; spores in chains, chains branched or simple, cylindric, trun- 
cate at the ends, 3 X 16/*. 
On decayed wood, Bemus Point, N. Y., July, 1913. 
This species resembles Cylindrium flavo-virens Bon., but the 
spores are larger and not curved. 
The type specimens are in the Carnegie Museum, Pittsburgh, Pa. 
Vaginata umbonata sp. nov. 
Pileus thin, convex or expanded, 3.5-5 cm. broad, distinctly 
conically umbonate, covered with triangular scales arranged in 
somewhat concentric zones, tan-colored, scales darker, margin 
thin, smooth ; gills 3-5 mm. broad, ventricose, sinuate, adnexed ; 
stem 9-12 cm. long, solid, equal, coneolorous, with long bulbous 
root ; volva fimbriate, adhering closely to the stem ; spores ovoid 
to ellipsoid, 5 — 7 /* (pi. uy. f. 1 ). 
Growing in sandy soil at Ohiopyle, Pennsylvania, August, 
1908. 
This species is closely related to Amanitopsis adnata (Smith) 
Sacc. in its adnate gills; to Agaricns ( Amanitopsis ) urceolatus 
Viv. in its umbonate pileus; and to Amanitopsis volvata (Peck) 
Sacc. in its floccose-scaly pileus. It is easily separated from these 
species by its conic umbo, concentrically arranged scales, and 
fimbriate volva. 
The type specimens are in the Carnegie Museum, Pittsburgh, Pa. 
Marasmius Morganianus sp. nov. 
Pileus membranaceus, convex, sometimes nearly expanded, 
glabrous, slightly rugulose on the margin, reddish-brown or 
rufescent, center darker, 2-5 mm. broad; gills few, subdistant, 
broad, adnate, pallid at first, darker when old ; ^tem 2-3 cm. long, 
slender, equal, rufescent at the base, pallid at the top, covered 
with a white pubescence ; spores fusoid or ellipsoid, 3-6 p. 
On fallen leaves, Somerset, Pennsylvania, August, 1906.
