302 FUNGUS-FLOKA. 



Lachnea, Phil., Brit. Disc., p. 216. 



The densely fibrous black hyphae at the base of the as- 

 cophore is the most pronounced feature of the present 

 genus. Tapesia differs in having the mycelium-subiculum 

 effused over the matrix and not localised at the base of the 

 ascophore. 



Plectania melastoma. Fckl., Symb. Myc., p. 324. 

 (fig. 40, p. 290.) 



Ascophore 2-3 cm. across, cup-shaped, disc black, exter- 

 nally tomentose, brown becoming brick-red towards the 

 margin ; stem very short, rooting by no means of a dense 

 mass of coarse black filaments; asci cylindrical, spores 8, 

 uniseriate, elliptic-oblong, smooth, hyaline, 21-25 x 9 /it; k 

 paraphyses very numerous, filiform, very slightly thickened 

 upwards.

Peziza atrorufa, Grev., Scot. Or. Fl., t. 315. 



On rotten sticks, partly buried trunks, &c. 



The external tomentum varies from mere pubescence to 

 bristly hairs in different specimens. Strigose root hairs 

 composed of blackish, septate hyphae 46 p. thick. Very 

 cartilaginous when dry. 



Sowerby 's specimen figured on pi. 149, Brit. Fung., 

 examined. 



EEINELLA. Quel. (emended). 



Ascophore sessile or narrowed into a short stem-like base, 

 closed at first, then more or less expanded ; externally pilose, 

 hairs everywhere alike in structure, thin-walled, septate, 

 cylindrical, obtuse, minutely rough ; asci cylindric-clavate, 

 8-spored; spores hyaline, elongated and narrow, 3-many- 

 septate ; paraphyses lanceolate.
