niliform paraphyses. The collections from Porto Bico and 



Grenada are probably rather immature, for many of their 



spores are even.

Fructifications scattered, re- 

 supinate, adnate, at first convex 

 and orbicular, soon expanded, 

 flattened, following the inequal- 

 ities of the bark, white, pruinose, 

 the margin thick, entire, blacken- 

 ing underneath ; in structure 800 

 H thick, somewhat stratose, com- 

 posed of densely arranged, sub- 

 erect, interwoven, heavily in- 

 crusted, hyaline hyphae 2-3 /x in 

 diameter under the incrustation, 

 of which much of the matter is 

 large, angular, crystalline grains ; 

 hymenium composed of clavate basidia 45-60x10-15 /x, and 

 of thin-walled, hyaline, flexuous, incrusted, hyphal paraphyses 

 with tips bushy, somewhat corymbosely branched, branches 

 2-3 n in diameter under their incrustation, not moniliform 

 and noteworthy, as are the hyphae, by the large amount of
