274 BRITISH DISCOMYCETES. 
On Hypoxylon multiforme, etc. - 
Minute, gregarious, crowdéd (Fries, l. c.). 
I have seen several things under this name, but none 
of them appear to me to answer the description. The 
Rev. M. J. Berkeley says some of the specimens referred 
formerly to this species certainly belong to Helotiwm 
pruinosum (Jerd).* : 
Name—?zf, upon, ogaipa, a sphere; growing on a 
Spheria. 
Doubtful species. 
70. Lachnella plano-umbilicata. (Grev.) 
Small, sessile, gregarious, whole plant white, globose- 
concave, at length quite plain; ciliated with horizontal 
white hairs at the margin; hymenium gently umbilicate. 
Peziza plano-wmbilicata—Grev., “Flo. Edin.,” p. 420; 
“Eng. Flo.,” v. p. 198; Cooke, “ Handbk.,” 2054. 
On dead nettles. 
Wholly white, remarkably plane, with a small dimple 
in the centre of the hymenium, which in old age 
assumes a yellowish tinge. The external surface is 
covered with white hairs, which form a beautiful ciliated 
margin not in the ‘least raised. The margin is so 
irregular, that if there had been fewer cilia it might 
have been called pectinate (Grev.). 
As far as I know, there exists no authentic specimen 
of this either in the Edinburgh University Herbarium or 
in the Kew Herbarium. 
Supcenus III.—Fieria, Fries. 
Cups sessile or subsessile; externally fibrose-striate 
with adpressed hairs; epiphytal. (Plate VIII. fig. 49.) 
Name—ibrinus, of a beaver; from the felty texture 
of the receptacle.
