CRYPTOGAMIA FUNGI. 209 



5. E. poputinum, immersed in deep hollows of the leaf, at first 

 pale, then reddish, at length dark purplish-brown ; filaments 

 opake, thick, irregular, somewhat divided and erose at the sum- 

 mit GREV. Crypt. Fl. t. 250. f. 2. PURT. Mid. Fl. iii. 315. 



Hob. On the leaves of poplars near Berwick. 



6. E. alneum, spots effused, irregular, orange-brown ; filaments 

 short, pellucid, divided at the top into short, subglobose, irregular 

 lobes HOOK. Scot. ii. 34. GREV. Fl Edin. 451. 



Hob. On the under surface of alder leaves, not common. 



111. FUSIDIUM. 



1. F. flavo-virens, mass irregular, thin, bright yellow or green- 

 ish GREV. Fl. Edin. 464. ; Crypt. Fl. t. 102. f. 2.

 A. Baird. 



112. SEPEDONIUM. 



1. S. mycophilum, bright orange, occupying the interior of dying 

 fungi; capsules exceedingly copious, globular, minute, mixed 

 with a few slender branched filaments GREV. Fl. Edin. 466. ; 

 Crypt. Fl. t. 198. Mucor chrysospermus, Sow. Fung. t. 378. 

 WITH. iv. 439. 



Hab. In decaying fungi, chiefly boleti. On a boletus near 

 Langton, pointed out to me by Mr Thomas Brown. 



The powder of this production is immiscible with water, and 

 has properties similar to that of the Ly coper da. In a na- 

 tural arrangement the genus ought to stand close to Ly- 

 cogola. 



113. CLADOSPORIUM. 



1. C. herbarum, blackish-green, short, velvet-like, tufted or 

 effused ; filaments rigid, opake, erect, irregularly and sparingly 

 branched GREV. Fl. Edin. 469. LINK in WILD. vi. 1. 39.

 surface of dead oak leaves ; and on dried agarics.
