HUMARIA. 419 



clusters, making the exterior minutely granular and the 

 margin irregular; asci cylindrical, apex somewhat truncate, 

 8-spored ; spores hyaline, smooth, continuous, elliptical, ends 

 rounded, 20-23 X 10-12 /x, obliquely 1-seriate; paraphyses 

 septate, sometimes nodulose, slightly clavate. 



Peziza hepatica, Batsch, Elench., fig. 138; Cooke, Mycogr., 

 fig. 85 ; Phil., Brit. Disc, p. 99. 



On the ground, and on rabbit's dung. Spring. 



Distinguished by the purple-brown or liver-coloured 

 ascophore. 



Specimen, in Cooke's Fung. Brit., ed. ii. 191. 



Humaria purpurascens. Sacc, Syll., viii. n. 476. 



Scattered or gregarious, narrowed into a more or less 

 distinct, short, stout, stem-like base, campanulate then 

 expanded, fleshy, glabrous, often somewhat irregular in 

 outline, entirely dingy livid-purple, 1-2 cm. across, flexible 

 and rather inclined to be gelatinous when moist; excipulum 

 and hypothecium formed of interwoven hyphae, which run 

 out, especially at the margin, into parallel, septate, obtuse, 

 closely packed, purple-tinged hyphae ; asci cylindrical, apex 

 somewhat truncate, 8-spored ; spores obliquely 1-seriate, 

 hyaline, continuous, elliptical, ends obtuse, usually 2-guttu- 

 late, 18-21 X 7 /x; paraphyses slender, slightly clavate. 



Peziza purpurascens, Pers., Myc. Eur., p. 242, t. 12, fig. 10; 

 Phil., Brit. Disc, p. 97; Mycogr., fig. 276. 



On the ground. 



Not a typical Humaria, exceptional in the structure of the 

 ascophore, and the flexible rather than brittle substance. 



Specimen in Cooke's Fung. Brit., ed. ii., n. 543, examined 



*** 



Entirely dingy green. 



Humaria jungermanniae. Sacc, Syll., viii. n. 584. 

 Ascophore 1-2 mm. across, sessile, fleshy, every part deep 

 verdigris green, convex then almost plane, quite glabrous, 

 excipulum composed of small parenchymatous cells ; asci 

 clavate, attenuated below into a thin pedicel ; spores 8, 

 uniseriate or often irregularly biseriate upwards, smooth, 

 hyaline or tinged with green at maturity, guttulate, 15-18 

 X 8-9 fji ; paraphyses numerous, about 1 • 5 /x thick below ;
