most of our members who have carefully examined the British 
Lycoperda spores will agree with me in saying that none of 
them are perfectly smooth if submitted to a Zeiss J water im- 
mersion objective. It would therefore be much better to 
classify our British species under two sections only as proposed 
by C. Van Bambeke in his paper in the Bulletin de la Société 
Mycologique de France,* namely, the Asterosporae and Sub- 
asterosporae. Under the Asterosporae we should range the 
large echinulate spored LYCOPERDON ECHINATUM, HOyLEl, 
ATROPURPUREUM, VELATUM and SACCATUM, and the Sué- 
asterosporae would include the remainder with generally 
smaller, olivaceous spores. 
In this brief review I have excluded some species of Massee 
enumerated thereunder as LYCOPERDA in his work as I con- 
sider the British BOVISTAE have distinct characters of their own 
in having free, pointed threads of capillitium. Nor can | 
agree with C. G. Lloyd’s definition of Morgan’s genus CALVATIA 
which he separates from LYCOPERDON on the ground that 
the peridium breaks up in its upper portion and has 
pedicellate spores in the former, whereas the latter is 
characterized by opening by a definite mouth and non-pedicellate 
spores, but if he is consistent then his Pratense section of Lyco- 
perda ought to be transferred to the former genus, as I take it 
that his LYCOPERDON PRATENSE is identical with my LYCo- 
PERDON DEPRESSUM Bon.,t but as he gives no authority for his 
names it is impossible to trace this. Equally his creation of 
BOVISTELLA for the pedicellate spored species of Lycoperdons 
will not hold water, as we have many of these in other species 
of Lycoperda, and for example I cite LYCOPERDON ATROPUR- 
PUREUM. 
I should add that an elongated cylindrical form of 
LYCOPERDON PYRIFORME is known as the var. EXCIPULIFORME 
(Desm.) and that a smaller, club-shaped, yellower form of 
EXCIPULIFORME is the variety FLAVESCENS of Quelet. 
In the external characters I omitted to mention that LYCO- 
PERDON PERLATUM is uwmbonate and PYRIFORME rather um- 
bonate. 
LYCOPERDON EXCIPULIFORME has the threads of the capil: 
litium sparingly or not at all branched and COOKE! has them 
also unbranched.
