PLEOTANIA. 301 



tate hyphae about 3 fi thick; asci clavate, apex slightly 

 narrowed, 8-spored ; spores irregularly 2-seriate, hyaline, 

 continuous, elliptic-oblong, 5-6 X 1 * 5-2 fx ; paraphyses 

 slender, cylindrical, hyaline. 



Peziza caesia, Pers., Syn. Fung., p. 657. 



On oak chips, and wood. 



Distinct from other species by the gregarious, grey asco- 

 phores being seated on a dense but thin, continuous, grey- 

 ish-white subiculum, which often forms patches several 

 centimetres in extent. The subiculum assumes a yellowish 

 tint on drying. 



Specimen in Cke., Fung. Brit., n. 562, examined. 



Tapesia sanguinea. Fckl., Symb. Myc, p. 303; 

 Phil., Brit. Disc, p. 281 ; Sacc, Syll., n. 1528. 



Asco])bores gregarious, sessile, closed at first, then plane 

 but having the margin permanently raised, about h mm. 

 across, entirely blackish-olive; cortex formed of parallel 

 rows of slender cells which run out into slender parallel, 

 olive hyphae at the margin ; seated on a spreading, thin 

 subiculum varying in colour from deep rose to blood-red, 

 formed of branching, septate hyphae, 3-4 //. thick ; asci 

 rather broadly clavate, apex obtuse, pedicel stout, short, 

 8-spored; spores hyaline, continuous, elliptic-oblong, 6-8 X 

 2 • 5-3 fx ; j>araphyses very slender, brownish at the slightly 

 thickened tips. 



Peziza sanguinea, Pers., Tent. Disp., p. 34. 



On wood of fir, &c. 



Distinguished by the minute, blackish ascophores being 

 seated on a broadly effused, deep red subiculum. 



Specimen in Karst., Fung. Fenn., n. 148, examined. 



PLECTANIA. Fuckel. (fig. 40, p. 290.) 



Ascophore shortly stipitate, cup-shaped, fleshy or slightly 

 tough, externally brown and flocculose, base coarsely stri- 

 gose or fibrous with black hyphae ; asci cylindrical, spores 

 8, continuous, hyaline, smooth ; paraphyses present.
