Hormisciopsis gen. nov. 
Pulvinate, effused, gelatinous, collapsing when dry ; mycelium 
well developed, filiform, branched; sporophore not differing from 
the mycelium, erect or subereot; spores in chains, bright-colored. 
This genus differs from H ormiscium in its gelatinous character. 
In gross appearance it is not unlike some species of Tremellaceae, 
particularly species of Exidia or Gnepinia. The manner of pro- 
duction of spores separates it entirely from this group. 
Hormisciopsis gelatinosa sp. nov. 
Pulvinate or effused, contorted, plicate, compact, appearing as 
though oozing out of the substratum, red to dark-red; mycelium 
filiform, branched ; sporophores not differentiated from the 
mycelium ; spores in chains, the chains branched, globose to ellip- 
soid, guttulate, somewhat granular, 5-6 X 6-10 /x. 
On decayed wood, Fern Hollow, Allegheny Co., Pennsylvania, 
August, 1907. 
The type specimens are in the Carnegie Museum, Pittsburgh, 
Pa. 
Arthrosporium album sp. nov. 
Plants gregarious, mycelium scanty; stroma conic or cylin- 
dric, 0.5-1 mm. high, white, composed of a fascicle of parallel 
hyphae, the fertile hyphae becoming free along the stroma or 
spreading above and forming a small head ; spores borne on 
sterigmata on the swollen ends of the fertile hyphae; spores 
hyaline, 3-septate, guttulate, cylindric-fusiform, 5-8X25-30 /i. 
On decayed log, Fern Hollow, Allegheny Co., Pennsylvania, 
1912. 
The genus Arthrosporium is used simply as a pigeonhole for 
this species. Its affinities are with several genera. It might be
