BRITISH SPHiEROPSIDEiE. 
Provisional List of Species hitherto found in the British 
Islands. 
By M. C. Cooke. 
In the following catalogue the arrangement is based on the 
third volume of Saccardo’s “ Sylloge,” with slight modifications as 
to the grouping. It includes all the species known to us, which 
have been discovered in Britain since the publication of the 
“ Handbook.” 
SPHiERQPSIDEiE, Lev. 
Sporules ( Stylospores and Spermatici of authors) without asci, pro- 
duced on more or less manifest basidia, or sporophores, enclosed 
within a perithecium. 
Fam. 1. SPHiERIOIDEiE, Sacc. 
Perithecia membranaceous, carbonaceous, or somewhat coria- 
ceous (not fleshy or brightly coloured) globose, conical, or lenti- 
cular, entire, immersed or superficial. 
Sub. -Fam. I. PHOMOIDEjE. 
Perithecia scattered, submembranaceous or carbonaceous, naked, 
usually papillate, not rostellate, opening by a pore. Sporules 
hyaline (rarely slightly coloured), for the most part continuous. 
Growing mostly on dead parts of plants. 
Gen. 1. PHOMA, Fries, Sacc. Syll. III., 65. 
Perithecia subcutaneous, then erumpent, submembranaceous, 
subcoriaceous, or subcarbonaceous, globose or compressed, smooth, 
erostrate, with a minute ostiolum, which is sometimes obsolete. 
Sporules ovoid, fusoid, cylindrical, rarely sphseroid, continuous, 
hyaline, often biguttulate. Basidia fiiliform, sometimes very short 
or obsolete, simple, rarely furcate.
