Otidea plebophora. Phil., Brit. Disc, p. 65; Sacc, 

 Syll., n. 362. 



Usually growing singly, narrowed to a very short stem- 

 like base, becoming rather widely expanded and shallowly 

 cup-shaped, usually somewhat oblique, 2-3 cm. across, en- 

 tirely of a yellowish-brown colour ; excipulum composed of 

 intricately interwoven, hyaline hyphae, 4-6 /a thick, running 

 out at the surface into an irregular layer of pale brown cells, 

 8-12 /i diameter ; externally ornamented with branched ribs, 

 which start from the base and often end in little pits ; disc 

 often venose ; asci narrowly cylindrical, 8-spored ; spores 

 obliquely uniseriate, elliptic-oblong, smooth, continuous, 

 hyaline, often 2-guttulate, 10-12 X 6-6 /a; paraphyses rather 

 stout, septate, apex clavate, 5-6 ix thick, straight or slightly 

 bent.

Sessile, caespitose, variously contorted and plicate, fleshy, 

 brittle, disc umber brown, externally paler and pruinose, 

 sometimes altogether paler and leather-colour or pale dingy 

 oohraceous, 5-8 cm. diameter ; when solitary or almost so, at 

 first globose, then expanding with the margin involute, finally 

 spreading and irregularly plicate ; excipulum spongy and 

 cavernous, due to the loose .weft formed by interlacing, hya- 

 line, thin-walled, flaccid, septate hyphae, cortex compact, 

 running out into irregular groups of cells that form the 

 scurfy exterior; asci cylindrical, apex slightly truncate, 

 8-spored; spores obliquely 1-seriate, hyaline, continuous, 

 smooth, usually 2-guttulate, 16-18 x 7-8 fj.; paraphyses 

 slender, septate; tip slightly clavate, often curved, and 

 sometimes branched.
