 the spores are also larger than in any other known species.

Dasyscypha laeteor (Karst.) Sacc. 



Ascophores gregarious or scattered, sessile, at first globose, 

 finally expanded, disc plane, with raised or spreading margin, 

 slightly fleshy, soft, 1*5 mm. across, disc dingy ochre, exterior 

 brown below, pale ochre above, margin white, densely fringed 

 with delicate, h}aline, cylindric-clavate, septate hairs in little 

 fascicles,' hairs 50-60 x 4-6 /x, shortly and sparsely pilose below ; 

 cortical cells oblong to globose, 8-10 x 6-8 /x; marginal, 6x4^1. 

 Asci cylindric-clavate, 50 x 6*5-7 /x, apex narrowed. Spores 8, 

 hyaline, obliquely biseriate, cylindric-fusiform, straight or 

 curved, 12-15 ^ ^"3 2-4 guttulate, smooth. Paraphyses sparse, 

 septate, filiform, 2 /x thick. 



Karsten, in his latest description, says this differs from 

 D. bicolor in the septate paraphyses, and thinner, closely septate 

 hairs, and in growing only on Riihus species.

Ascophore sessile, attached by a central point, scattered, 

 solitary or casspitose, sometimes contorted through mutual 

 pressure, open from the first, disc slightly concave, then plane, 

 often undulate and lobed, honey colour then tinged pale red- 

 brown, exterior reddish ochre, dark brown at the point of 

 attachment, ^margin thin, even or wavy, i-i'5 mm. across; 

 excipulum of densely interwoven, hyaline, septate hyphai 3-5 /x 

 thick, passing at the cortex into g'lobose, brownish cells, 10-14 /x 

 diam., slightly larger and darker tow^ards base, paler and oblong 

 8-10x6 /X, and in parallel rows towards the margin, at the 

 extreme margin subclavate 3-4 /x diam. Asci narrowly clavate, 

 80-90 X 7, apex rounded, pedicel stout, curved and swollen at 

 the foot. Spores 8, when young biseriate above, uniseriate 

 below filling the ascus ; when mature, in two rows in the upper 

 part, hyaline, minutely biguttulate, elliptic-fusiform 10-13 x 3-4 i^- 

 Paraphyses slender, straight, hyaline 2 /x thick. 



The spores are shot from the asci very freely when examined 

 in water. Some spores exhibit faint indications of a central 

 septum. Tissue of ascophore soft and fragile.
