referred to by Rostafinski as a type of F. flagellifcra, is the form with 
olivaceous capiUitium and nearly smooth spores. The type of Trichia 
metalUca Berk., from Tasmania (K. 1741), is almost destroyed, but 
the spores and sporangium-wall indicate that it was of the Badminton 
form. The type of P. elegantula Rost., from Sweden (K. 1743), is 
a more perfect development with distinctly warted spores. P. cuprea 
Mass., from Scarborough and Carlisle (K. 1744, 1745), is a frequent 
form with minutely warted spores, and is similar to specimens of 
P. flagdlifera in Broome's collection. The large gatherings from 
Lyme Regis, showing all degrees of variation, demonstrate that the 
specimens in the collections to which different names have been given 
represent one species, whose diverging forms are too inconstant to be 
defined even as varieties.

Genus 43.— LYCOGALA Micheli, Nov. PI. Gen., p. 215 (1729). 
^aEthalia subglobose or conical, with a cortex consisting of two 
or more closely combined layers of different structure, the outer 
containing large cell-like vesicles, either enclosed or superficial, 
and traversed by interlacing double-walled threads, which pene- 
trate the homogeneous inner layer at numerous points, their 
inner walls only being continuous with the tubes of the capillitium; 
capiUitium grey or colourless, of wrinkled or nearly smooth 
branching tubes, attached to all parts of the cortex, with numerous 
rounded free ends. Isolated vesicles filled with granular matter 
are often found scattered among the spores. 
The Plasmodium of Lycogala miniatum first rises from the wood 
as a group of small coral-red papillae, which soon extend to form a 
cushion-like mass of closely convoluted veins or sporangia • these are
