496 MR. F. CURREY ON BRITISH FUNGI. 
as Mr. Berkeley remarks in his ‘Outlines of British Fungology, has usually yielded 
nothing but the commonest moulds; so that the present plant is interesting from its 
habitat. I have received the same species, again growing on leather, from my friend the 
Rev. J. Gagliardi, who met with it on the Simplon, and the same gentleman has since 
found it in Yorkshire, on the leather and elastic of an old shoe. 
ASCOBOLUS ARGENTEUS, Curr. Cooke, J. c. 
Gregarious, exceedingly minute, barely visible to the naked eye, subpyriform, of a 
silvery-white colour; sporidia elliptical, colourless, 0:0005 inch long. Found by Mr. 
Broome on cow-dung, at Eltham in Kent, November 1863. Fig. 21 represents asci and 
sporidia, magnified 430 diameters. 
This species is remarkable from its excessively small size and silvery-white colour. It 
is perhaps the smallest of all the described Ascodoli.
