ANNALS OF THE MISSOURI BOTANICAL GARDEN 



niliform paraphyses. The collections from Porto Rico and 



Grenada are probably rather immature, for many of their 



spores are even. 



Specimens examined:

 of Jamaica, type. 



Porto Rico: Vieques Island, Campo Cieto to Ensenada 

 Hondo, J. A. Shafer, 3048 (in N. Y. Bot. Gard. Herb., and 

 in Mo. Bot. Gard. Herb., 55453). 



Grenada: Grand Etang, R. Thaxter, comm. by W. G. Far- 

 low, 6. 



5. A. candidus (Schw.) Burt, n. comb.

Type: in Herb. Schweinitz, Herb. Fries, and Curtis Herb. 



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 

 /x thick, somewhat stratose, com- 

 posed of densely arranged, sub- 

 erect, interwoven, heavily in- 

 crusted, hyaline hyphae 2-3 n in 

 diameter under the incrustation, 

 of which much of the matter is 

 large, angular, crystalline grains ; 

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

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

 with tips bushy, somewhat corymbosely branched, branches 

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

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