On modelling clay. 
Occasionally on common black modelling clay, where, 
to the artist, it is a troublesome intruder, it being gene- 
rally necessary to work the part again to get rid of it. 
It is held to the clay by very fine attenuated cobweb- 
like fibres from the sides, as it were, to assist the little 
knotty root (Sowerby). 
The Rev. M. J. Berkeley, in whose possession Sowerby’s 
original specimens were, kindly gave me some of the 
modelling clay on which the Peziza had grown, but the 
Pezizd had long since disappeared. On the surface of 
the clay, when it came into my hands, were a number of 
small, hard, seed-like bodies partly imbedded, around 
some of which was a growth of mould giving them the 
appearance of Sowerby’s figure. I have kept the clay 
damp under a bell-glass for some years, but no Peziza 
has appeared. 
Genus II.—Pstnopezia. Berk., “ Outl.,” p. 873. 
Indeterminate, immarginate, agglutinate; hymenium 
always exposed. (Plate V. fig. 23.) 
The typical representative of this genus has only 
been found once. It resembles a Rhizina more than a 
Peziza, though at first included with the latter, but it 
has not the peculiar roots of the former. The spores 
differ also from those in Rhizina.
