DESCKIPTIONS OF 
hyssoidei. The number of genera here has been more than 
doubled, chiefly by the exertions of the German Cryptoga- 
mists ; in most instances upon a sufficient foundation, al- 
though in some their distinction of specific character seems 
to be somewhat trifling; as between Virgaria and Hapla- 
ria, Polyactis and Aspergillus, Verticillium and Botrytis, 
Ruhigo and Erineum. 
The following plants belong to the order above mention- 
ed, and I have been obliged to adopt the new genera, as 
no others would receive them ; those, however, to which 
my specimens must be referred, are distinct and satisfac- 
tory. 
Sporotrichum, Link, 
Fila 7'amosa implexa sporis globosis aid omltbus vage 
inspersa, 
Sporotrichum minutum, mihi. 
Plate V. fig. 1. 
S. subrohmdum minutum candidum, Jilis laxe intricettis 
sporis numerosis ovalihus. 
Hab. In stercoie, autumno hyemale. 
Small, very white, tufted, sometimes crowded together, 
tufts about half a line in diameter. Threads under the 
microscope, loosely interwoven, seldom and irregularly 
branched, and somewhat attenuated. Sporules oval, or 
suboviform, very numerous, and not so small as in many 
species. At Braid Hermitage, on dung.
