. POCILLUM — STAMNARIA, 231 



present species has only once been collected in Britain — 

 Epping Forest — so far as I am aware. 



Pocillum Boltoni. Phil., Grew, vol. xvi. p. 94 ; Sacc, 

 Syll., viii. n. 2502. 



Minute, scattered, at first cylindrical, then becoming 

 nearly turbinato-truncate, glabrous, shining, horn-coloured, 

 soft, watery, much contracted when dry ; hymenium plane 

 or a little depressed ; asci broadly clavate ; spores 8, 

 elongated, subcylindrical, obtuse at the ends, 40-50 X 3-4 fx; 

 paraphyses filiform, thickened at the apices. 



On dead Equisetum, lying in water. 



Ascophore 100-200 fx broad, 300-400 ll high. The spores, 

 which are large for the size of the plant, are straight or a 

 little bent, colourless, and furnished with several large 

 vacuoles. They have a propensity to throw out long germ- 

 tubes while yet in the ascus. The excipulum is composed, of 

 elongated septate threads, but showing no colour, as in the 

 other species of the genus. (Phillips.) 



Unknown to me. 



STAMNAPJA. Fuckel. (figs. 15-17, p. 156). 



Gregarious, minute, erumpent, shortly stipitate, closed at 

 first then expanding, but the opening remaining contracted 

 and surrounded by a delicate, minutely fimbriate, scarious 

 margin; horny, glabrous, rigid when dry; asci clavate, 

 apex narrowed and with the wall thickened, 8-spored; 

 spores elongated, hyaline, continuous, 2-seriate ; paraphyses 

 septate.

 Disc, p. 321; Rehm, Krypt.-Flora Disc, p. 465; Sacc, Syll., 

 viii. p. 620. 



Peziza, of old authors. 



Distinguished by the horny, perfectly glabrous ascophore 

 with a somewhat narrowed, delicately bordered mouth. 



Stamnaria equiseti. Sacc, Syll., viii. n. 2559 ; 

 Rehm, Krypt.-Flora Disc, p. 466, figs. 1-7, p. 449. (figs. 

 15-17, p. 156.)
