HUM ARIA. 421 



Peziza KeitMi, Phil., Myco. Scot., p. 308; Brit. Disc, 

 p. 98. 



This species has an outline much commoner amongst the 

 Ascoboli than the Pezizae, being thick and fleshy, the disc 

 only slightly depressed, the plant forming a flattened 

 sphere. 



Unknown to me. The above description is from Brit. 

 Disc, p. 98. 



Humaria domestica. Mass. 



Gregarious or crowded, sessile, seated on a delicate white 

 subiculum formed of branched, septate, hyaline hyphae, at 

 first almost cylindrical then expanding until saucer-shaped 

 or almost plane, slightly fleshy, about § mm. across, salmon- 

 colour or yellowish with a pink tinge; cortex parenchy- 

 matous, cells irregularly polygonal, 8-10 ft diameter, giving 

 origin, especially below the margin to delicate white hyphae, 

 which fix the plant to the substratum, and run off to form 

 the subiculum ; asci cylindrical, apex rounded, 8-spored ; 

 spores obliquely 1 -seriate, hyaline, smooth, continuous, 

 elliptical, ends obtuse, 17-18 x 9 ft ; paraphyses slender, 

 septate, slightly clavate.

Pyronema domesticum, Sacc, Syll., viii. n. 407. 



On damp plaster, also on burnt ground and damp paper. 



Very close to H. omjphalodes, differing in the somewhat 

 larger spores, and less developed subiculum. 



Sowerby's type specimen, now in Herb., Berk., Kew, 

 examined. 



***** Pise reddish-brown or umber. 



Humaria cervaria. Sacc, Syll., viii. n. 566.

 at the crenulate margin, glabrous, chestnut-brown; disc 

 concave, waved ; asci cylindrical, abruptly narrowed at 

 the base ; spores 8, oblong-elliptic, smooth, eguttulate, 

 15 X 7 /*; paraphyses linear, abundant, forked at the
