CURREY——MYCOLOGICAL NOTES. 229 
say that the identity of the two plants can be considered to 
be established, but there is at least good ground for the suts- 
picion of a relationship between them, and it is desirable that 
all such cases should be noticed, with the view of inducing 
further observations. 
Cenangium Cerasi, Pers.—The reproductive organs of this 
and several other Cenangia have been commented on by 
M. Tulasne in a paper in the last volume of the 3d series of 
the ‘ Ann. des Sciences.’ He describes the pycnidia as tu- 
bular processes, generally czespitose, confluent at their base, 
their cavities communicating with one another. The pycnidia 
contain large curved stylospores, and sometimes also (aecord- 
ing to M. Tulasne) delicate curved spermatia, but the latter 
I have not seen. In some specimens of Cenangium Cerasi 
which I met with at Eltham, in Kent, I have observed the 
pycnidia to be somewhat different from those described by 
M. Tulasne, approximating, in fact, very closely to his de- 
scription of those organs in Cenangium fuliginosum. The 
pycnidia in my specimens formed irregular tubercles, the 
substance of which was hollowed out here and there into 
simple cavities, filled with stylospores growing from short 
basidia which lined the walls of the cavities. Thin vertical 
sections of the tubercles are represented in Pl. XI, figs. 11, 
12, which show also the cavities and the contained stylo- 
spores, the latter being colourless, fusiform, curved, and when 
ripe (I think) triseptate. There was no appearance of the 
commencement of the formation of any ostiolum or opening 
for the exit of the stylospores, which I have little ‘doubt 
would escape by irregular apertures, as has been observed in 
Cenangium fuliginosum. There is, in fact, hardly any diffe- 
rence between the pycnidia just described and those of C. 
fuliginosum, except that im the Jatter they are said to be of a 
dark colour, whereas in Cenangium Cerasi they are pale. It 
may be that the pyenidiaof C.Cerasi, described by M. Tulasne, 
were in a more advanced state than those above mentioned, 
it beig quite possible that at a later period than that 
shown in figs. 11, 12, the cavities might become confluent 
at the bottom, and tubular by the opening of the apex. As, 
however, the stylospores in my specimens were perfect, the 
pycnidia must be considered as fully developed, and I have 
therefore thought it worth while to notice the form of them, 
as presenting a marked departure from those hitherto de- 
scribed, and at the same time an approximation to those of 
a nearly allied species.
