. Everhartia li^natilis n. sp. — Plate XX. figs. 10-12. 



Scattered, superficial, stipitate or substipitate, yellowish 

 becoming blackish towards the base, subcylindrical or expand- 

 ing upwards, 2 50-400 x 100-150/1. Spores hyaline, terminal, 

 3-septate, cylindrical or slightly flattened, 4// in diameter, the 

 rounded base and snout-like apex approaching one another in 

 a single convolution 12-13x8-9//: extruded in a yellow 

 viscous rounded mass. Sporiferous hyphae septate, subdi- 

 chotomously branched, mingled with longer usually simple 

 sterile hypha;. 



On wet logs. Connecticut. 



I his species occurs not uncommonly about New Haven on 

 very rotten wet logs. It differs from E. hymcnuloidcs Sacc. & 

 Ell. in being stipitate as well as in its very distinct and smaller 

 spores. The latter are produced in enormous quantities ad- 

 hering to the apex in a yellowish viscous drop. The spores 

 germinate readily in water, producing single hypha? from the 

 convexity of each segment. 



Everhartia hvmexuloides Sacc. & Ellis. — Plate XX, 



"gs. 13-14. — Figures of the spores of this species are given 

 for comparison drawn from material distributed in Ellis N. 

 A. F. No. 969 on dead leaves of Sorghum nutans. In this 

 species the sporodochia are sessile and ill defined, the spores 

 being produced terminally on short simple hyphfe (fig. H)- 

 The spores are formed in a helix of several convolutions, 

 16x20//, and are about 3.5-4/1 in diameter, extruded in a 

 viscous mass and surrounded by a coarsely granular greenish 



mucus.
