HUMAKIA. 413 



hyaline, smooth, usually 1-2-guttulate, rather narrowly 

 elliptic-fusoid, ends rather acute, 26-30 x 8 p. ; paraphyses 

 septate, the strongly clavate apex 8-10 p. thick.

The present species hovers between Humaria and Neottiella, 

 agreeing with the last-named in having soft, thin-walled, 

 septate hairs at the margin, especially when young, after- 

 wards becoming almost or quite glabrous. The above 

 description covers what is, in the opinion of Berkeley, 

 Cooke, and Phillips, the true P. ollaris of Fries, which is 

 described as follows in Syst. Myc., ii. p. 68 : 



Closely gregarious, without a trace of a stem, fleshy- 

 waxy, fragile, hemispherical, at length expanded, and oblong 

 or wavy from mutual pressure ; externally naked, but when 

 young the margin is furnished with fascicles of whitish, 

 inflexed hairs. When young 2-4 lines, at length up to 1 in. 

 broad. Very frequent in Swedish pine woods among moss 

 and fallen pine leaves. Summer and autumn. (Fries.) 



[Humaria roumegueri. Sacc., Syll., viii. n. 515. 



Gregarious, sessile, fleshy, orbicular, margin distinct, thin 

 and menibranaceous, erect, paler than the clear orange- 

 yellow disc, externally pale yellow, glabrous, 34 mm. 

 diameter ; hypothecium formed of stout, interlaced hyphae ; 

 excipulum parenchymatous, cortical cells large, somewhat 

 hexagonal, 20-35 p. diameter; asci cylindrical, 8-spored; 

 spores obliquely 1-seriate, smooth, hyaline, usually 12 

 guttulate, elliptic-fusoid, ends narrowed, 24-27 X 9 p.; 

 paraphyses slender, apex rather abruptly and strongly 

 clavate and often curved, filled with orange granules when 

 fresh.

Specimen from Karsten examined. 



Karsten states that this species is distinguished from, 

 allies H. fusispora, Berk. by the paraphyses alone becom- 

 ing blue with iodine ; this reaction, however, I find is not 

 evident after the specimen has once been dried.
