This species is very distinct from Sphæria maerosfoma, Tode. I t ia possible
that Mr. Currey’s fig. 64 may belong to it. Externally there is considerable
resemblance, except th at the perithecia are smaller. 'The sporidia are ('0009

in each cell. When free the sporidia exhibit a distinct outer
transparent membrane which invests them.—Coohe Trans. Bot.

On decorticated twigs of Maple. Jan. Shere, Surrey.
The conspicuous green patches on wbieh the peritbecia are uraally found
resemble those caused by the mycelium of Helotinmæmginosum, indeed, it is
not improbable that the latter originates tbe patches upon which tbe Sphæria
locates itself. Hitherto tbe green patches and the perithecia have always been
found associated. The perithecia are larger and more prominent than in Lo-
phiostoma bicuspidata, and both are very distinct from S. macrostoma, Tode, in
their fructification, although somewhat resembling small forms of it in external
appearance. Tbe fruit much resembles th at of some species of Massaria.
