270 BRITISH DISCOMYCETES. 



CI. Lachnella Tami. (Desm.) 

 Var. Humuli (no v. var.). 



Gregarious, sessile, hemispherical, then expanded, 

 pubescent, white or very pale yellow ; asci clavate ; 

 sporidia 8, fusiform or nearly oblong, 8 x 2/z ; paraphyses 

 filiform, scarce. 



On Hwniulus lupulus. 



Cups 200 to 400^u. So near to L. Tami that it hardly 

 deserves to be called a variety, except for more developed 

 hairs and different host-plant. The hairs are very short, 

 colourless, and non-septate. 



Darenth ! (Dr M. C. Cooke), 



62. Lachnella BerJceleii. (Blox.) 



Gregarious, sessile, cups hemispherical, furfuraceous- 

 floccose, almost pruinose ; hymenium concave, tawny ; 

 asci clavate ; sporidia 8, oblong, subfusiform or cymbi- 

 form, 5 — 8 X 2/u ; paraphyses not seen. 



Peziza Berkeleii — Blox. in B. and Br., " Ann. Nat. 

 Hist," No. 770 ; Cooke, " Handbk.," No. 2057. 



On dead stems of Umbelliferce. 



" Very minute, gregarious, often crowded, hemi- 

 spherical, with the margin at first strongly inflected, 

 clothed with furfuraceous-yellowish flocci. In the 

 younger specimens the orifice is distinctly marked with 

 radiating lines. Hymenium concave, tawny ; asci 

 clavate ; sporidia "0003 to - 0004 inch long, oblong, sub- 

 fusiform or cymbiform." 



" Under the lens the coat consists of very short flocci, 

 intermixed with minute hyaline amorphous scales. We 

 cannot point out any very, near ally, except possibly P. 

 humvlis, Desm. It resembles P. apala more closely 

 than any other species with which we are acquainted ' :
