hyaline, contintious, elliptical, 1-seriate ; paraphyses adhering

Desmazierella acicola. Libert, Ann. Sci. Nat., 1829, 

 p. 82 with fig., Phil., Brit. Disc, p. 283 ; Sacc, Syll., viii. 

 n. 1594. 



Ascophores scattered, sessile, at first closed and turbinate, 

 then expanded and orbicular, 3-5 mm. across; disc slightly 

 concave, brown, minutely velvety, due to the projecting tips 

 of the paraphyses ; margin fringed with tapering, pointed, 

 septate, dark brown hairs 130-160 x 6-7 /a; externally 

 clothed with a tomentum formed of irregularly branched, 

 .septate, brown hyphae 4^5 jx thick ; flesh thin, greyish ; asci 

 elongated, narrowly cylindrical, narrowed downwards into 

 a long, slender, curved pedicel, 8-spored; spores obliquely 

 . 1-seriate, hyaline, continuous, usually 2-guttulate, elliptical, 

 15-16 X 8 /u,, paraphyses adheriug in bundles, becoming 

 free, black, and sharp-pointed at the tips, longer than the 

 a»ci. 



On dead leaves of Pinus sylvestris. 



Specimen examined from Madame Libert's Crypt. Ard., 

 n. 24. 



Ascophore about 21 lines broad. This appears at first 

 as a minute, hairy Chaetomium-l&e hody, nearly black, 

 afterwards expanding into a sublentiform disc. The brown 

 hairs of the hymenium, being prolongations of the paraphyses, 

 give this plant a striking character. (Phillips.) 



DASYSCYPHA. Fries, (figs. 1-2, 12, 24-26, p. 166.) 



Ascophore minute, shortly stipitate or sessile, closed at 

 first then expanding until nearly or quite plane, thin and 

 delicate in texture, externally and the margin pilose, hairs 

 thin-walled, cylindrical, obtuse, often rough with crystals of 

 lime, stem short, slender; asci cylindric-clavate, 8-spored;
