102 The North American Cup-Fungi 



with age or from mutual pressure, at first pale-brown or smoky, 

 becoming darker with age, reaching a diameter of 2-5 cm.; 

 hymenium concave, darker than the outside of the apothecium, 

 becoming ahnost black with age or with an olive tint from the 

 spores which have dusted out over its surface; asci cylindric or 

 subcylindric, tapering rather abruptly below into a stem-like 

 base, reaching a length of 275 ^ and a diameter of 12-14 /z; 

 spores 1-seriate, ellipsoid, at first hyaline and smooth, containing 

 one or two oil-drops, finally becoming sculptured and smoky- 

 brown, 10 X 15-17 m; spore-sculpturing usually consisting of one 

 large protuberance at either end of the spore and irregular 

 reticulate markings over the surface of the spore, with irregular 

 lumps at various points on its surface, the ridges of the reticu- 

 lations so arranged as to give the spore a somewhat striate ap- 

 pearance; paraphyses strongly enlarged above, where they reach 

 a diameter of 8 /j., minutely granular within and dilutely colored. 



On the ground in woods, often among mosses. 



Type locality: New Jersey. 



Distribution: New York, New Jersey, Maine and Mon- 

 tana.

Apothecia gregarious or scattered, sessile, discoid to shallow 

 cup-shaped, externally slightly roughened, pale brownish-black, 

 reaching a diameter of 1 cm.; hymenium concave, dark-brown or 

 becoming almost black or with a slight greenish tinge which 

 seems to be due to the spores which have been dusted out over 

 the hymenium; asci cylindric above, tapering below into an 

 irregular stem-like base, reaching a length of 300-350 n and a 

 diameter of 15-17 ^t; spores 1-seriate or occasionally slightly 

 crowded, ellipsoid to subfusoid, containing one or two oil-drops, 

 at first smooth, becoming sculptured, pale smoky-brown, 10-12 

 X 22-25 n; spore-sculpturing taking the form of irregular reticu- 

 lations, the ridges of the reticulations strongly projecting, giving 

 the spore a decidedly roughened surface; paraphyses rather 

 strongly enlarged above, reaching a diameter of 6 /x at their apices, 

 pale-brown. 



On the ground in damp places. 



Type locality: Staten Island, New York. 



Distribution: Known only from the type locality.
