264 ANNALS OF THE MISSOURI BDTANICAL GARDEN 



Fung. 6: 457. 1888. — Grandinioidea flavum (Swartz) Banker, 

 Torr. Bot. Club Mem. 12: 179. 1906 (in part). 



Type: in Kew Herb, and Curtis Herb. 



Pileus helmet-shaped to flabelliform, vaulted, thin, yellowish 

 brown, slightly streaked behind, glabrous; stem very short, 

 brownish; hymenium whitish, sprinkled with many scattered 



strong bristles. 



Pileus 3^-4 cm. long, nearly as broad. 



On dead wood. Martinique and Venezuela. 



Patouillard has noted in the place cited that the pileus may 

 attain a diameter of 15 cm., and that the stem is short, thick, 

 and black at the base. Banker includes M. brunneoleuca in 

 M. fiava as a poorly developed form. 



I have examined no specimens of M. brunneoleuca. The 

 description of the species is that given by Berkeley & Curtis. 





EPITHELE

Resupinate thelephoraceous fungi lacking an intermediate 

 layer and having the hymenium bristling with short cylindric 

 fascicles of hyaline hyphae which arise from the subhy menial 



tissue. 



The type species is Epithele Dussii. 



The four species of Epithele, known at present, are very thin 

 and delicate in structure and constitute a natural group which 

 is not connected with Mycobonia by thick resupinate species 

 with either an intermediate layer or with a doubtful inter- 

 mediate layer — doubtful merely because the hyphae are inter- 

 woven rather than arranged longitudinally in the region of the 

 intermediate layer. Epithele Typhae (Pers.) Pat. is a frequent 

 species in Europe on dead leaf bases of Typlta; if present in the 

 United States, it may have been regarded as one of the Hyd- 

 naceae on account of the hyphal fascicles in the hymenium.
