HUMAKIA. 409 



Peziza pilifera, Cooke, Mycogr., p. 50, fig. 92 ; Phil., Brit., 

 Disc, p. 93. 



Leucoloma ascoboloides, Rehm, Ascom., n. 54 (not P. asco- 

 boloides, Mont., nor De Not., nor of Schweinitz). 



On sandy ground, often among moss. 



Somewhat approaching the genus Neottiella, but appearing 

 to have more affinity with certain species of Humaria, as H. 

 omphalodes, H. subhirsuta, &c The external hairs are ex- 

 ceedingly delicate and cobweb-like, and are difficult to see 

 in dried specimens. 



Specimens examined in Rehm's Ascom., nos. 54 and 854. 



Humaria carbonigena. Sacc, Syll., viii. n. 506. 



Gregarious or usually densely crowded and irregular 

 from mutual pressure, sessile and applanate ; disc plane or 

 slightly convex, often undulate, orange-yellow, sometimes 

 pale yellow or with a tinge of brown, externally paler, 

 extreme margin brownish ; rather flesh}', 3-8 mm. across ; 

 hypothecium and excipulum formed of interwoven, hyaline, 

 septate hyphae which are inflated into large pyriform or 

 subglobose cells at intervals, and passing into a parenchy- 

 matous cortex, of irregular, polygonal cells 10-18 /x broad, 

 these run out at the margin into short, obtuse, septate, 

 brown hyphae ; numerous brown or sometimes almost 

 hyaline, septate hyphae spring singly or in clusters from 

 the cortical cells, and attach the fungus to the substratum; 

 asci cylindrical, apex slightly truncate, 8-spored, spores 

 obliquely 1-seriate, hyaline, elliptical, ends rather acute, 

 usually 2-guttulate, 19-22 X 9-11 jx; paraphyses septate, 

 containing orange granules, clavate tip 6-7 /x thick. 



Peziza carbonigena, Berk., Flora Tasm., ii. p. 274; Cooke, 

 Mycogr., fig. 29; Phil., Brit. Disc, p. 103. 



On charcoal-beds, scorched places, &c 



Type specimen examined. 



The species was founded on specimens from Tasmania, 

 with which British specimens agree in every respect. 

 The colour of the disc varies from pale, clear yellow, 

 through orange-yellow, to yellowish brown, or even a 

 tinge of flesh-colour. Sometimes the specimens do not as 

 a rule exceed 2 mm. in diameter, at others they average 

 much more.
