the stipe. In the plant observed, 8 to 10 long lamellae, 4 to 6 inter- 

 mediate ones much shorter. Subhymenium loosely branched, obovate 

 cells arising from the trabeculse and terminating in the basidia, or in 

 the forms with lamellae arising from a rudimentary trama in the 

 lamella. Basidia short clavate, abruptly narrowed into a pedicel, 

 9-12 X Q-dfj^, 4-spored. Spores obovate-oblong, elliptical, proximal 

 end pointed, 6-8 x 3-4 ii, hyaline, smooth, granular. Stipe thread- 

 like, with scattered hairs bearing a short echinulate cell on the end. 

 Base of stipe only slightly broadened. 



Eomycenella is related to Discocyphella^ P. Hennings, but differs 

 in the dissolving hymenium and the fact that the pileus is not gela- 

 tinous nor the stem horny. From Cymetella^ Patouillard (placed 

 with Agaricacese) it differs in the trabecular pileus and the dissolv- 

 ing hymenium; and from Gloeocephala'* (Clarvariacese) Massee, 

 which has one-spored basidia. The latter should be placed in the 

 Thelephoraceoe." 



TROGIA 



Plants small, growing on wood, laterally sessile, tough, persistent, 

 reviving when wet; margin regularly lobed; gills fold-like; spores 

 white. 



We have but one species which we insert from records by Schwei- 

 nitz and Curtis, as we have not found it. 



Trogia crispa Fr. 



The following is from Murrill (:f;r. Am. Flora, 9: 164. 1910 (as 

 Plicatura) : 



"Pilei crowded, subimbricate, usually sessile, persisting, reviving 

 when moistened, 1-2 cm. broad ; surface reddish-yellow or tan, paler 

 toward the margin, often whitish-villose when young; margin beau- 

 tifully lobed: context fleshy membranaceous, tough, thin, white; 

 lamellic white, narrow, vein-like, irregular, continuous or interrupted, 

 sometimes branched, edges crisped, obtuse, white or bluish gray: 

 spores cylindric, smooth, hyaline, 4 x 1/*:"
