The above-named author has been at great labour in the
divisions of this enormous genus, and has done much towards
its elucidation. Our present species is contained in his first
series ;
I. ALBURIA. Carnosoe vel carnoso-membranaceoe, pruinosoe, vel
Jloccoso-furfuraceoe. Subterrestres.
1. H e l v e l l o i d e æ . Cupula semper aperta (D isá n a ) vel j u nior
connivens. Magnæ terrestres,
f f t Pustulatæ. Subsessîles, integroe, centrales, extus granulosa
vel verrucosa.
This last division contains 10 species, of which P . repanda
is the first, P. cerea and P. vesiculosa, both figured by
S o w e r b y (the latter admirably), are the only others hitherto
found in this country.
A striking characteristic of this small group is, that the
pileus never becomes convolute when split.
