HUMARIA. 411 



On burnt ground, charcoal, and cinders. 



Colour of ascophore variable, orange, reddish, or pink. 

 The spores appear to be a little larger in Continental than 

 British specimens. The subiculuni is more evident in the 

 present than allied species. 



Specimens examined in Phil., Elv. Brit., n. 109, and 

 Fuckel, Fung. Khen., n. 1218. 



Humaria melaloma. Mass. 



Caespitose or gregarious, sessile, closed at first, then 

 gradually expanding until almost plane, rather fleshy, 

 3-4 mm. across, often wavy or distorted from lateral 

 pressure ; dingy orange, margin minutely irregular, darker ; 

 cortex parenchymatous, cells irregularly hexagonal, 8-12 /x 

 across, running out at the margin into tufts of cylindric- 

 clavate, obtuse, usually 1-2-septate, brown hairs, 30-40 x 

 7-10 fx; asci cylindrical, apex rounded, 8-spored ; spores 

 obliquely 1-seriate, hyaline, continuous, elliptic-oblong, ends 

 obtuse, usually 2-guttulate, 15-18 x 8/x; paraphyses slender, 

 septate, slightly clavate.

 Syll., viii. n. 401. 



Peziza melaloma, Cke., Mycogr., fig. 67 ; Phil., Brit. Disc, 

 p. 109. 



On the ground, especially where burnt. 



Near to H. subhirsuta but differing in the dingy colour of 

 the ascophore ; darker, minutely irregular margin, and in 

 the paraphyses not originating in clusters. Patouillard 

 considers the present to be distinct from the Peziza melaloma 

 of Persoon ; this I have no means of ascertaining ; it is 

 certainly Pyronema melaloma of Fckl., Fung. Rhen., n. 1221. 



Humaria macrocystis. Sacc, Syll., viii. n. 467. 

 Ascophores gregarious or scattered, sessile, cup-shaped 

 then almost plane, margin entire, slightly raised, glabrous ; 

 disc slightly concave, orange-red, externally brownish, 

 glabrous above, furnished with numerous septate, coloured 

 hyphae springing from the basal cells of the excipulum, and 

 fixing the plant to its substratum; excipulum parenchy- 

 matous, inner cells small, cortical ones large, mostly 

 hexagonal, up to 35 /x diameter; asci cylindrical, 8-spored: 

 spores hyaline, elliptic-oblong, smooth, usually 2-guttulate,
