MurRILL: PoLyporRACEAE OF NortH AMERICA 417 
2. Hapalopilus sublilacinus (Ell. & Ev.) 
Mucronoporus sublilacinus Ell. & Ev. Bull. Torrey Club, 2'7: 50. 
1900. 
This species was collected by Langlois on pine logs in Louisi- 
ana and very doubtfully and provisionally assigned to H. gi/vus. 
In some ways it does resemble that species, but it is larger, with 
concentrically furrowed surface and long, lilac-colored tubes. The 
spores are hyaline, but very distinct from those of 1. gi/zus. 
3. Hapalopilus licnoides ( Mont.) 
Polyporus licnoides Mont. Pl, Cell. Cuba, 401. pl. 16. f. 2. 1842. 
Polystictus licnoides Fr. Nov. Symb. 92. 1851. 
Polystictus subglaber Ell. & Macbr. Iowa Univ. Bull. Nat. Hist. 3: 
193. 1896. 
This well-known fungus is exceedingly common in tropical 
parts of America, occurring on dead wood of various kinds and 
presenting a variety of forms according to locality and habitat. 
The best early description of it is that made by Montagne. Fries 
may have described the species under P. crocatus, but this is not 
yet well determined. According to Romell, Polyporus xerophyl- 
faceus Berk. (Hook. Jour. Bot. 8: 200. 1856), described from 
Brazilian collections, is a synonym of the present species. Speci- 
mens from Guadaloupe in the Paris herbarium are named /omes 
Khortalsti Lév., which latter isa Sumatran species. Young plants 
collected in Nicaragua by C. L. Smith have recently received the 
name Polystictus subglaber, said to differ from P. dicnoides in having 
smaller pores and no spines. Resupinate forms from the southern 
states are usually known as P. crocatus, possibly because this 
species was once so identified from South Carolina. 
In many ways #7. “icnoides and H. gilvus are strikingly alike 
and approach very near to each other in some varieties, but they 
are usualiy readily distinguished by the numerous concentric zones 
which ornament the surface of the former species. Spores and 
cystidia correspond closely. H. gi/vus extends much farther north, 
however, and is abundantly collected where H. /icnoides is never 
found. Among the numerous collections of this species examined 
are the following : Jamaica, Underwood, Earle ; Cuba, Underwood 
& Earle; Mexico, Smith; Nicaragua, Smith; Louisiana, Langlois ; 
Florida, Martin, Calkins, Lloyd.
