Exotic Species 



S. album lUirt, n. sp. 



l\l)e: in Mo. Bot. Gard. Herb. 



Fructifications rcsupinate, effused, adnate, thick, fleshy, white, 

 somewhat colliculose, pulverulent, contracting in drying and 

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

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

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

 hyi^hae 3^ [x in diameter, occasionally nodose-septate, not in- 

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

 septate, 75 X 6 [i, confined to the outer 150 [jl of the hyinenium, 

 only rarely reaching the surface and protruding; spores simple 

 hj-aline, even, 10-12-15 X 7-9 ^, borne singly on the outer 3 

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

 h\Tnenium composed of slender, hyaline, matted and coiled para- 

 j^hyses or hyphal branches 2 (x in diameter. 



Fructifications 1-3 cm. long, 1-13^ 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 hjTnenial surface of coiled 

 paraphyses, absence of probasidia, and hjphae 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. 



Specimens examined:

comm. by J. R. Weir (in Mo. Bot. Gard. Herb., 59315). 



S. cinnamomeum Burt, n. sp. 



TjT^e: in Farlow Herb, and Mo. Bot. Gard. Herb. 



Fructifications resupinate, effused, dry, hj'pochnoid, small 

 pieces separable when moist, Brussels brown, somewhat collic- 

 ulose, somewhat velutinous, the margin concolorous, with 

 surface irregular, somewhat raduloid; in section 210 [x thick, 

 colored, stratose, consisting of 2 strata, each composed of sub- 

 erect, loosely interwoven, rigid h^^phae 3 [x in diameter, colored
