HUMAEIA. 407 



cells irregularly polygonal, large, cortical ceils, 12-16 ja dia- 

 meter ; asci cylindrical, narrowed at the base into a slender, 

 often curved pedicel, 8-spored ; spores obliquely 1-seriate, 

 hyaline, continuous, elliptical, ends blunt, often 2-guttulate, 

 at first smooth, finally very minutely reticulated, 13-15 x 

 8-9 /a; paraphyses septate, slender, often branched below, 

 apex clavate, 6-8 /a thick, containing orange granules. 



Peiiiza rutilans. Fries, Syst. Myc, ii. p. 68 (1823) (not of 

 Phil., Brit. Disc). 



Specimen named by Fries, and now in Kew Herbarium, 

 examined. 



On the ground among moss, &c. 



Sometimes solitary, at others gregarious, fleshy, brittle. 

 Fries placed P. rutilans in his tribe Humaria, of which he 

 says, " Cupula nee pruinosa, neque vere villosa," Syst. Myc, 

 ii. p. 67, hence it is somewhat remarkable that it should 

 ha;ve been confounded with the species called P. polytricM, 

 which is truly villoss. 



The present species has been confused with Neottiella poly- 

 tricM (Sohum.) in this country. For synonymy and con- 

 sultation of exsiccati relating to the two species mentioned, 

 see " Grevillea," vol. xxi. p. 107. 



Humaria Piggotti. Sacc, SylL, viii. n. 545. 



Gregarious or crowded, sessile, seated on a thin, downy 

 white hypothecium, subglobose and closed at first, then 

 saucer-shaped, rather fleshy, 3-4 mm. across, disc pale brick- 

 red, externally paler ; hypothecium and excipulum formed 

 of branched, irregularly swollen hyphae often thickened at 

 ,the point of bifurcation ; these hyphae become denser at the 

 .periphery or cortex, and give origin below the margin to 

 elender, branched, aseptate hyphae, which attach the fungus 

 to the substratum, and also form the thin subiculum ; asci 

 cylindrical, apex rounded, 8-spored ; spores obliquely 1-se- 

 .liate, hyaline, smooth, continuous, eUiptioal, ends blunt, 

 15-17 X 8-9 /x; paraphyses numerous, very slender, not 

 thickened at the tips.
