Exotic Species 



S. album Burt, n. sp. 



Type: in Mo. Bot. Gard. Herb. 



Fructifications resupinate, effused, adnate, thick, fleshy, white, 

 somewhat colliculose, pulverulent, contracting in drying and 

 forming a few large fissures at 2-3 mm. apart, the margin some- 

 what tomentose; in structure 600-700 [i thick, not colored, com- 

 posed of densely interwoven and ascending, even- walled, hyaline 

 hyphae 3-4 (x in diameter, occasionally nodose-septate, not in- 

 crusted; no probasidia seen; spore-bearing organs straight, 3- 

 septate, 75 x6|a, confined to the outer 150 (x of the hymenium, 

 only rarely reaching the surface and protruding; spores simple 

 hyaline, even, 10-12-15 X 7-9 n, borne singly on the outer 3 

 cells of the spore-bearing organs so far as observed ; surface of the 

 hymenium composed of slender, hyaline, matted and coiled para- 

 physes or hyphal branches 2 [l in diameter. 



Fructifications 1-3 cm. long, 1-1}^ cm. wide. 



On bark of dead, fallen branches of Nothofagus. New Zealand. 

 December. 



S. album somewhat resembles Corticium portentosum and is ex- 

 ceptional, if there is no error in the collector's data, by its occur- 

 rence on dead, fallen branches. The hymenial surface of coiled 

 paraphyses, absence of probasidia, and hyphae extending from all 

 parts of the substratum into the fructification without consolida- 

 tion into supporting pillars are additional characters for recog- 

 nition of the species.
