138 FUNGUS-FLORA. 



rowed at the tip, pedicel slender, wall rather thick, 8-spored ; 

 spores irregularly 2-seriate above, elliptic oblong, ends obtuse, 

 hyaline, smooth, 1-septate, 10-15 x 3-5-4 p; paraphyses 

 slender, slightly thickened and brownish at the tips, ad- 

 hering together.

Pycnidia. Perithecia spurious, emmpent, 3 mm. high, 

 conico-cylindrical, very fragile, powdery, blackish-brown, 

 terminated by a minute grey globule ; spores narrowly 

 fusoid, curved, hyaline, 1-septate, 15 x l'5-2 p..

Specimen in Berk., Brit. Fung., n. 112, examined. 



Fam. V. BULGARIEAE. 



Ascophore erumpent or superficial, sessile, base sometimes 

 narrowed and stem-like, discoid and applanate, turbinate, or 

 clavate ; glabrous, gelatinous or waxy-gelatinous when grow- 

 ing, rigid and horny when dry ; excipulum parenchymatous, 

 or composed of interwoven hyphae ; asci cylindrical or rarely 

 many-spored ; spores continuous or septate, hyaline or 

 coloured ; paraphyses present. 



The more or less gelatinous consistency of the excipulum 

 is the most pronounced feature of the present order; when 

 dry it is horny and rigid, becoming again gelatinous when 

 soaked in water. In the larger species, as Bulgaria, the* asco- 

 phore is blackish, in the smaller species usually clear-co- 

 loured, orange, red, &c. The asci do not project above the 

 level of the disc, as in the Ascoboleae. 



All the species grow on wood, herbaceous stems, or leaves, 

 as saprophytes.
