648 Murrill: Polyporaceae of North America 



Specimens collected in Brazil by Moller are referred to this 

 species by Bresadola (Hedwigia 35 : 281. 1896) with the follow- 

 ing notes : " Species haec vegeta ex integro alba, postice longe re- 

 supinato-producta, interdum ex integro resupinata. Sporae hyal- 

 inae, subglobosae, 5 — 6 x 4 — 4^2 <>■ ', hyphae subhymeniale 

 3/4 — 4j4 I* latae, septatae." The identity of the two plants is 

 doubtful. 



12. Coriolus membranaceus (Sw.) Pat. 



Boletus membranaceus Sw. Prodr. 148. 1788. — Fl. Ind. Occ. 3: 



1922. 1806.

 Coriolus membranaceus Pat. Tax. Hymen. 94. 1900. 



Originally described from plants collected on dead wood in 

 Jamaica as follows : 



" B. acaulis gregarius proliferus submembranaceus laevis radiatus albus, poris 

 erosis diflbrmibus." 



This description is much enlarged in Swartz's later work. The 

 species is exceedingly abundant in tropical America on all kinds 

 of dead wood and large collections have been brought to the New 

 York Botanical Garden in recent years, as the following list will 

 show : 



Porto Rico, Earlc, Underwood & Griggs, Heller, Wilson jp ; 

 New Providence, E. G. Britton 732 ; St. Kitts, Britton & Cowell 

 7 10; Cuba, Underwood & Earle 372, 8jj, iji8, 13J4, I 376 y 

 f S7S> Earle, Wilson, Murrill ; Jamaica, Earle 232, 323, 601, 611, 

 Underwood 2326, Miss Robinson ; Nicaragua, Smith ; Colombia, 

 Baker. 



13. Coriolus Flabellum (Mont.) 



Poly poms Flabellum Mont. PI. Cell. Cuba. 388. //. 13. f. 2. 1842. 

 Well described and finely figured by Montague from plants 

 collected on dead branches and trunks in Cuba. Types at Paris 

 are well preserved. Although nearly related to C. pargamenus, it 

 is quite distinct both in form and habit. It is more difficult to 

 separate it from C. membranaceus.
