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

 conico-cj'lindrical, very fragile, powdery, blackish-brown, 

 terminated by a minute grey globule; spores narrowly 

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

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 ; glahrous, gelatinous or waxy-gelatinous when grow- 

 ing, rigid and horny when dry; excipulum parenchymatous, 

 or composed of interwoven hyphae ; asoi 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.
