Apothecia subglobose, sessile or substipitate; hymenium 

 covering all of the exposed surface of the apothecium, brownish; 

 substance fleshy or slightly cartilaginous; asci broad-cylindric to 

 subclavate, 8-spored; spores globose, at first smooth, becoming 

 sculptured, slightly colored; paraphyses rather slender. 



Type species, Sphaerosoma Jiiscescens Klotzsch.

Apothecia subglobose or reniform, short-stipitate or attached 

 by a small tuft of mycelium near the center of the under side, 

 reaching a diameter of 2-6 mm.; hymenium covering all of the 

 exposed surface of the apothecium, pale-brown; asci broad- 

 cylindric or clavate above, narrowed below, reaching a length 

 of 250-300 jj. and a diameter of 28-30 /x; spores at first 2-seriate 

 or irregularly crowded near the end of the ascus, gradually 

 separating and becoming 1-seriate, at first smooth, becoming 

 sculptured, reaching a diameter of 20-27 /x; spore-sculpturing 

 taking the form of reticulations, the reticulations 2-3 jx deep as 

 indicated by the projections about the periphery of the spore, 

 the ridges often appearing as spines; paraphyses filiform, curved 

 at the ends, enlarged and cemented together, forming a rather 

 firm epithecium. 



On the ground under leaf-mould. 



Type locality: Berkeley, California. 



Distribution: California; also in (Europe?).

Apothecia sessile, at first subglobose, becoming expanded and 

 subdiscoid, or convex-hemispheric and Sphaerosoma-Vike, rather 

 small, reaching a diameter of 2-5 mm.; hymenium occupying 

 the upper surface only or covering the entire exposed surface and
