amination of the specimen showed the capillitium to consist of a 
network of hyaline threads, with many lime-knots often combined to 
form a pseudocolumella ; the spores are purple and more or less 
ellipsoid, Jenne 13-15 x 11-14 
Dp a alba DC. was also abundant last August at Chaul 
End ; we fotinad about twenty large ethalia had matured round the 
base of a stack of clover and on loose straw amongst which the 
cream-white plasmodium was still creeping. The spores in different 
zethalia show much variety both in colour and marking. In some 
they are of the usual type, purplish Brey and strongly spinulose. 
In others the agin exactly resemble those of the form found by 
Mr. R. E. Fries in Bolivia in 1902, and ‘daceriicd by him in Arkiv fiir 
Botanik, 1903, Bd. i. 66, under the name of Spumaria alba var. 
dictyospora ; the ey are rich dark brown, nearly black, and marked 
with a close reticulation of raised bands. Intermediate forms were 
found in other sxthalia connecting the extremes. It is satisfactory 
hat this variety is now recognized as occurring in Britain, and that 
its close relation to the type is completely established.
