CURREY——-MYCOLOGICAL NOTES. 231 
Spheria Tiliaginea, Currey.—Under this name I have de- 
scribed, in the ‘ Philosophical Transactions’ for 1857 (p. 545), 
a Spheeria which occurs in the neighbourhood of Blackheath 
upon Lime. I stated it to belong to the division Circinate, 
but observed that the perithecia were more deeply immersed 
in the inner bark than is usual in that division. In the spe- 
cimens there described the sporidia, although fully formed, 
appeared to be hardly quite ripe; in fact, the plants had not 
attained their full age. I have since found, also upon Lime, 
a Spheeria not distinguishable in its perithecia or sporidia 
from S. Tiliaginea, and which, I do not doubt, is the same 
species in a more advanced stage of growth. This latter 
Spheria belongs, however, to the Circumscripte, the peri- 
thecia being imbedded in a white woody stroma, and the 
stroma itself surrounded by a manifest conceptaculum. The 
existence of the conceptaculum would afford no ground for 
separating the species from S. Tiliaginea, for it may well be 
that the conceptaculum does not appear until the plants 
have attained some age; and besides this, I suspect that 
other species of Spheeria occur, in which the conceptaculum 
is sometimes present, and sometimes not. I have referred to 
this circumstance in my Synopsis of the Kew Spherie, in 
the last part of the ‘Transactions of the Linnean Society,’ 
under S. éaleola, and need not dwell upon it here. 
Within the conceptaculum above alluded to were con- 
tained a number of perithecia, and the interest of the plants 
consisted in the fact that some of the perithecia were 
ascigerous and others stylosporous. The ascigerous peri- 
thecia produced asci and sporidia exactly resembling those of 
Spheria Tiliaginea, as figured in the volume of the ‘ Phil. 
Trans.’ above-mentioned, pl. xxv, fig. 12. The stylo- 
sporous perithecia, or pycnidia, as they ought, perhaps, to 
be called, produced oblong or elliptic stylospores, sometimes 
slightly incurved on each side in the middle, with a granular 
endochrome, of a greenish colour, and with usually a very 
distinct double outline. ‘These stylospores are drawn highly 
magnified; in fig. 14 their length varies from 0:0005 to 
0:0007 inch. My former observations showed that this 
Spheria produced spermatia and naked stylospores, besides 
the normal sporidia, and it now appears (if the species 
in discussion be identical with S. Tiliaginea, of which I 
have no doubt) that there is also a fourth kind of fruit, viz., 
stylospores contained within perithecia. 
Spheria ciliaris, n. sp.—This Spheeria occurred on branches 
of ash at Weybridge, in October, 1857, and is particularly
