equal, solid, glabrous, paler than p., 4-5 cm.; sp. irregularly oblong, nodulose, 
1 1-1 2 x 8-9 fi ; c. wanting. 
On the ground. New Ireland. 
One of the very few species having nodulose spores and no cystidia.

margarispora, Sacc., Syll. v, p. 781 ; Ag. (. Ino .) margarispora^ Berk. ms. in 
Cke., Hdbk., ed. ii, p. 157 ; Gke., 111 ., pi. 505. 
P. campanulate, then expanded and broadly umbonate, often flexuous, silky, clad 
with adpressed fibrillose scales, fawn-colour or pale yellowish-brown ; 3-5 cm. ; 
g. adnexed, pallid ; s. solid, equal, fibrillose, pallid ; sp. subglobose, coarsely nodulose, 
8-9 n ; c. absent. 
On the ground. Britain. 
Resembles I. asterospora in general appearance and in spore characters, but 
differs in the absence of cystidia. I. eutheles differs in the smooth spores. 
(Type specimen examined.) 
Bucknalli, Massee (sp. nov.). 
P. campanulato-convex, fibrillose, with a few squamules near the disc, brownish, 
1-2 cm. ; g. adnexed, thick, rather distant, rusty-brown, edge minutely fimbriate ; 
s. equal or slightly thickened at the base, slender, fibrillose, brownish, 2-4 cm. ; 
sp. irregularly oblong, one end obliquely apiculate, rather coarsely nodulose, 15- 
17x8-9/4; c. absent; basidia clavate, exceptionally large, 70-80x16-18/4, 
4-spored. 
On the ground under bushes. Britain (Leigh Down, Bristol. Cedric Bucknall). 
A little insignificant-looking brown Fungus, without any marked external 
characteristics, but at once distinguished by the size of the basidia, which are more 
than twice the size of those of any other known species. The spores and periphyses 
are also exceptionally large. 
The fimbriate edge of the gills is due to the presence of numerous large thin- 
walled clavate cells about 75-85x15-20/4. These differ in structure from the 
cystidia, which spring from the sides and not from the edge of the gills. 
Spores rough , no knowledge of cystidia. 
* Stem whitish or pallid.
