606 MURRILL : POLYPORACEAE OF NORTH AMERICA 



of 5. striata, but Montague is decidedly opposed to this opinion 

 and specimens are not at hand to settle the question. Compare 

 his remarks on this point : 



" Si Ton ne considere que l'hymenium de ce Lenzites, il est 

 evident qu'on le distinguera mal du L. striata ; mais si Ton ob- 

 serve la disposition du duvet dresse et comme conglutine qui 

 forme les zones ccncentriques, la profondeur des sillons qui sepa- 

 rent ces zones, et l'aspect rugueux et peluche qui en resulte, carac- 

 teres que je ne rencontre dans aucun des nombreux individus du 

 L. striata, on se convaincra promptement que, quoique voisines, 

 ces deux especes ne sauraient etre confondues." 



Daedalea Bitrscrae Pat. Jour, de Bot. 3 : 341. 1889. De- 

 scribed from plants found on rotten wood of Bitrscra gummifera 

 in Martinique by Duss. It is said by the author to be easily dis- 

 tinguished from all its congeners by the yellow powder which 

 covers its pores in the young stages. I have not seen the type 

 plants. 



Daedalea jamaicensis P. Henn. Hedw. 37: 281. 1898. Col- 

 lected on dead wood at Port Antonio, Jamaica, and thus described : 



" Pileo suberoso-spongioso, dimidiato, sessile, interdum imbri- 

 cato, zonato sulcatoque rugoso, rufo-brunneo vel atro-violaceo 

 nigricante, zonis obscurioribus, margine pallidiori, acuto ; intus 

 cinnamomeo ; hymenio poroso-labyrinthiformi vel sinuoso-lamel- 

 loso, subochraceo vel subcinerescente." 



This species is very near to Scsia Berkeleyi. Further study of 

 the type plants, however, is necessary in order to decide whether 

 or not the two species are synonymous. 



Ischnoderma Karst. Medd. Soc. Faun, et 

 Fl. Fenn. 5 : 38. 1879 



This genus was founded upon IscJi. resinosum (Schrad.) and 

 four other European species, the one here mentioned being the 

 nomenclatorial type. Karsten describes the genus as follows : 



" Receptaculum pileatum, sessile, primitus subcarnoso-suc- 

 cosum dein induratum, crusta tenuiore tectum. Hymenium heter- 

 ogeneum. Pileus azonus. Pori integri, demum subsecedentes." 



Ischnoderma fuliginosum (Scop.) 



Boletus fuliginosus Scop. Fl. Cam. ed. 2. 2: 470. 1772. 

 Boletus rubiginosus Schrad. Spic. Fl. Ger. 168. 1794.
