430 FUNGUS-FLOEA. 



mat&us, cells polygonal, 15-11 /x diameter, running out in 

 irregular clusters to form tte external warts ; asci cylindrical, 

 8-spored ; spores obliquely 1-seriate, hyaline, smooth, elliptic- 

 oblong, ends rounded, 20-15 x 10-12; paraphyses clavate, 

 septate, tips brown, 



Geopyxis hufonia, Sacc, Syll., viii. n. 252. 



On damp ground, rubbish-heaps, &c. 



Specimen determined by Berkeley examined. 



Distinguished from P. vesiculosa by the dark brown disc, 

 and more distinctly warted exterior. P. cochleata differs in 

 habit and in the pruinose exterior. The present species is 

 placed by Saccardo in Geopyxis, but the narrowed base never 

 assumes the appearance of a stem, and is often obsolete.-
