LEUCOSPORI. iSl 



minutely strigose especially at the base, margin paler, sprinkled P!eurotus. 

 with a few meal-like scales; upper stratum gelatinous, cinereous, 

 beneath which the flesh is white and very thin. Stem none. 

 Gills pure white, rather distant, the alternate ones shorter, 

 narrow, linear. 



Minute. Gregarious. Allied to A. applicatus. 

 On dead herbaceous stems. Rare. Oct. 



Name xv^eAAov, the hollow of the ear. From its shape. Berk. Mag. Zool. 

 and Bot. i. t. 15. /. 3. Out. p. 138. C. Hbk. n. 131. Illust. PL 244. Fr. 

 Hym. Eur. p. 180. 



395. A. applicatus Batsch. Dark cinereous. Pileus 4-6 mm. 

 (2-3 lin.) broad, when young cup-shaped, orbicular, adnate behind, 

 villous at the base, commonly sessile, more or less pruinate; when 

 fuller grown more or less reflexed, never dimidiate, smooth or 

 slightly villous, slightly striate when damp. Gills few, rather 

 thick, broad, distant, paler than the pileus and here and there 

 whitish at the edge. 



Varying in colour, cinereous- or azure-blue-blackish, dark or bluish-grey. 

 The pileus is occasionally extended in a stem-like form (but there is never the 

 rudiment of a true stem) with the gills radiating from a central point. Habit 

 and stature wholly those of A. striatulus, &c., but thicker, firmer, and clothed 

 with a gelatinous pellicle. 



On dead branches, ash, c. Common. Autumn-Spring. 



Fries found it chiefly on willows. Name applicatus, closely attached.

 grey, membranaceous, reniform or dimidiate, stemless, minutely 

 downy, margin involute. Gills rather distant, pallid. 



On larch-stumps. Apethorpe, 1859. Sept. 



It seems very closely allied to A. reniformis, but that species is smooth, 

 shortly stipitate and broader. Fr. Name after Lieut. Julian C. Hobson.

397. A. striatulus Fr. Pale cinereous. Pileus very small, 4-6 

 mm. (2-3 lin.) broad, always sessile, not extended behind, cup- 

 shaped, very tender, smooth, pellucid, striate. Gills few, distant, 

 of the same colour as the pileus or whitish. 



Gregarious. Easily escaping observation from its minuteness. Wholly 

 withering and corrugated when dry. Very changeable in different stations.
