lilac. Basidia subglobose to oblong, 12 x 8-11; sterigmata 
8-10 x 6-7. Spores subfusiform, curved, 12 x 7p. Basal 
hyphae septate, without clamp-connections, 4-6 in diameter. 
In a large patch on the bark of an old birch log, Weybridge, 
Jan. 1922. 
The spores of this specimen agree better in size with those of 
the var. lilacea Bres. than with those of the type, which were 
described as 15 « 8. It seems probable that the species varies 
both in colour and in spore-size. The shape of the spores is 
characteristic.

TULASNELLA ALLANTOSPORA Wakef. et Pears. sp. nov. 
Fungus effusus, tenuissimus, ceraceus, hyalinus vel levissime 
lilacinotinctus. Basidia obovata, 7-10 x 6y. Sterigmata el- 
liptica, 7-9 x 5m. Sporae cylindraceae, curvulae, utrinque 
attenuatae, g-10 x 3-4. Hyphae basales 2-3 septatae, non 
nodosae.

This species forms an exceedingly thin film, scarcely visible 
to the eye when looked at direct except as a slight dullness of 
the surface of the wood. When the specimen is tilted so as to 
catch the light, however, the fungus appears as a delicate 
“bloom”’ with a very faint pinkish or lilac tinge. The species 
is recognisable by its delicacy and the small curved spores.

Pie need ishaya|\. The species is probably not uncommon, but 
micvospora. x 550. it has rarely been found in a condition good 
enough for description. The colour when dry 
is very like that of T. violacea, but the small size of spores and 
hyphae is distinctive for T. muicrospora.
