2G0 BRITISH DISCOMYCETES. 



P. sulphureo-ccesia — Schum., " SaelL," p. 432. Helotiwm 

 albo-luteum — Karst., " Myco. Fenn.," p. 160. Lachnea 

 variecolor — Gill., " Champ.," p. 83, c. i. 



On rotten wood. 



Cups 250 to SOOfi broad. 



Gregarious, thickset, not adnate, waxy, rather firm, 

 scarcely 1 line broad, regular ; margin entire, denticulated, 

 closed when dry, granuliform, persistent, so slightly 

 tinged with yellow that it can scarcely be called straw- 

 coloured (Fries). 



Inserted on the authority of Sowerby's P. hydnoides, 

 quoted by Fries as this species. Having examined the 

 original specimen of Sowerby, I was unable to detect any 

 asci or sporidia. The dimensions of the sporidia are 

 from Karsten. 



Name — Varius, various, color, colour. 



43. Lachnella grisella. Cooke and PhiL 



Cups gregarious, sessile, rarely substipitate, at first 

 turbinate, then hemispherical, very pale brown, fur- 

 furaceous-tomentose, perpendicularly striate ; margin 

 whitish, fimbriate ; hymenium brown ; asci clavate ; 

 sporidia 8, oblong-fusiform, 4 — 7 X 1 — 1'5/x ; paraphyses 

 slenderly filiform. 



Peziza grisea — Carmichael in Herb. Kew., No. 82. 



On dead decorticated wood.

 coloured hairs can only be seen when magnified about 50 

 diameters. 



The locality is not given, but, having been collected 

 by the late Dr. Carmichael, it was probably from Scot- 

 land.

 and fleshy, turbinate, finely tomentose, citron-colour ;
