ascophore, and the rough exterior departing in these points 

 from the typical structure of Humana. The mature asco- 

 phores resemble superficially the apothecia of some lichens. 

 Specimen in Rehm's Ascom., n. 403, examined.

 10-18 fx diameter, internally with a lilac tinge ; asci 

 cylindrical, apex rounded, 8-spored ; spores obliquely uni-

Type specimen examined. 



Humaria violacea. Sacc, Syll., viii. n. 597. 



Ascophores gregarious, subsessile, contracted into a very 

 short, stout base ; fleshy and succulent, brittle, closed and 

 almost globose when quite young, then becoming saucer- 

 shaped, finally expanded with the disc more or less undulate 

 and the margin wavy ; disc dark brown with a violet tinge, 

 the violet colour becoming more pronounced as the fungus 

 dries ; outside pale violet near the margin, covered with a 

 dense white down near the base, 1-2 ■ 5 cm. across ; hypo- 

 thecium composed of interwoven hyphae, which pass in the 

 excipulum into subglobose cells 25-35 /x. diameter, but 

 mixed with hyphae and inflated cells, cortex parenchy- 

 matous, cells small ; asci cylindrical, apex truncate, base 

 stout, often somewhat bulbous, 8-spored ; spores obliquely 

 uniseriate, hyaline, smooth, continuous, elliptic-oblong, ends 

 obtuse, usually 2-guttulate, 12-14 x 7-8 /jl ; paraphyses 

 slender, apex often rather wavy, clavate, yellowish-brown.
