58 FUNGUS-FLOEA. 



HIENEOLA. Fr. (emended), (fig. 4, p. 56.) 



Cartilagineo-gelatinous, soft and tremelloid when moist. 

 Sporophore cup-shaped, rigid when dry, reviving when 

 moistened, but not becoming inflated. Basidia rod-shaped 

 or fusoid, transversely septate, cells each bearing a single 

 monosporous sterigma ; spores oblong, curved. 



Hirneola, Fries, Fung. Natal, p. 24; Sacc. Syll. vi. 

 p. 764. 



In the British species the hyinenium is variously plicate, 

 the pileus or barren surface minutely velvety. 



Hirneola auricula-judae. Berk. (fig. 4, p. 56. ) 



Thin and elastic when moist, becoming blackish or dark- 

 brown ; hyinenium venoso-plicate ; spores reniform, 20-25 

 X 7-9 //, ; pileus greyish-olive, minutely toraentose. 



Hirneola auricula-judae, Berk., Out!., p. 289, t. 18, f. 7 ; 

 Cke., Hdbk., p. 349. 



On elder and elm. From 1-3 inches broad. 



[Hirneola polytricha, Mont. Has occurred on imported 

 timber, but is not a British species.] 



TREMELLINEAE. 

 EXIDIA. Fr. (emended), (figs. 8, 9, p. 56.) 



Gelatinously distended, tremelloid, submarginate or 

 effused, often papillose ; basidia globose or ovoid, typically 

 longitudinally cruciately divided, bearing four elongated, 

 stout sterigmata ; spores reniform, for a long time continuous, 

 becoming 1 many septate on germination, each cell or 

 loculus of the spore giving origin to a very short promy- 

 celium bearing a crown of strongly curved sporidiola. 



Exidia, Fries, Syst. Myc. ii. p. 220; Sacc. Syll. vi. 

 p. 772. 



Exidia glandulosa. Fries, (fig. 9, p. 56.) 

 Flattened, thick, gelatinous, becoming blackish; disc 

 covered with minute papillae; below greyish and sub- 

 tomentose ; spores reniform, 12-14 x 4-5 p..
