4°5 X 3m or 4p in diameter. Hyphae distinguished with diffi- 
culty, recorded as 2:5 in diameter, with clamp-connections, 
by Bourdot and Galzin. 
On rotten decorticated wood, Mulgrave Woods, Yorkshire, 
C. Crossland, Oct. 1912; Horsley, Mar. 1921, A.A.P. 
This species may be more common than the above two widely 
separated records would indicate. It is one of the very delicate, 
easily overlooked forms. The first specimens sent by the late 
Mr C. Crossland were in excellent condition, as his consignments 
always were, but the species was not then recorded because it 
was hoped that further confirmatory specimens would be re- 
ceived. Until the Horsley specimen, however, none has been 
forthcoming. The Horsley gathering is much more scanty, but 
the habit and characteristic spores leave no doubt that it is 
the same species. 
The measurements of spores and basidia given above are 
from the Mulgrave specimen, and agree with those of the 
type, a fragment of which was kindly communicated by 
M. Bourdot. 
SACCOBLASTIA Moeller, Protobasidiomyceten, 1895, p. 162. 
Effused, floccose or gelatinous. Basidia cylindrical, trans- 
versely septate, arising from a probasidium which remains as 
a lateral, sac-like attachment at 
the base of the basidium. Ste- 
rigmata lateral. Spores hyaline, 
smooth. 
Saccoblastia sebacea Bourd. et Galz. 
in Bull. Soc. Myc. Fr. xxv, 
1909, p. I5. 
Effused, greyish, thin, fleshy, at 
first rather firm in texture, later 
becoming slimy-gelatinous. Hy- 
menium delicately pruinose and 
somewhat granulose when in good 
condition, as seen under the lens. 
Probasidium 15-25 x 7-9, ovoid 
to oblong, pendulous, collapsing 
as the basidium matures and often 
breaking away in the preparation 
of sections. Basidia cylindrical,
