BURT—THELEPHORACEAE OF NORTH AMERICA, IX 193 
or wrinkled surface, are scattered throughout the fructifi- 
cation. 
Fruetifieations of type 2-6 2-4 mm.—15 fructifications on 
an area 44X2 cm. 
On bark of frondose trees. Jamaica and Cuba. October to 
January. 
In the original description A. seriatus was regarded as al- 
lied to A. candidus, but it is much closer to A. nivosus, differ- 
ing with the latter from A. candidus by convex surface of 
fructification, by margin not at all free nor reflexed, and 
by inerusting matter of hyphae not occurring in large crystal- 
line grains. All the collections which I have referred to A. 
seriatus have been scanty and bearing few spores; this species 
seems distinct from A. nivosus by the absence of clavate or 
cylindric gloeocystidia and by having the paraphyses spirally 
twisted and usually distinct from their tips to about the base 
of the basidia, and by having characteristic globose organs 
scattered throughout the sections, such as occur in Corticium 
pallidum Bres. and have been regarded and figured by v. 
Hohnel & Litschauer as gloeocystidia.!
