and again incrassated, consisting of numerous slightly constricted 
oblong joints ; endochrome containing a single nucleus. 
Resembling somewhat in structure 7. stilbosporoides, Corda, 
of which we have an authentic specimen, but differing greatly in 
habit.

b. spherieformis, Berk. & Br. On dead stems of herbaceous 
plants, Apethorpe. On decorticated branches of Pinus sylvestris, 
Wraxall, Som. 
Our specimens exhibit rather a different form from that figured 
by Corda. Instead of being widely diffused they present little 
Spheria-hke tufts, and have a highly developed hyphasma, con- 
sisting of forked threads, at the apices of which the short chains 
of spores are fixed. The form of these is identical with what was 
observed by Corda, and we regard the species as the same with 
his, though constituting a distinct variety. 
465. T. basicola, n. s. Hyphasmate repente ramoso hic illic 
assurgente ; floccis fertilibus brevibus 5-7-articulatis fastigiatis ; 
articulis non constrictis sero caducis, ultimo obtuso. At the base 
of stems of peas and of Nemophila auriculata, King’s Cliffe. 
Black, effused. Hyphasma creeping, branched, here and there 
rising from the general mass and giving off fascicles of short fas- 
tigiate fertile threads consisting of from 5-7 articulations. Arti- 
culations not constricted, ultimately separating, the last very ob- 
tuse. Hach endochrome has usually a single nucleus. 
A very curious species, distnguished from most Torule by its 
articulations not being constricted. In the plant on Nemophila 
the fertile threads grow singly, but there is no other difference. 
It is either destructive of the plant on which it grows, or is de- 
veloped on it in consequence of previous disease.

t. 12. fig. 5. On old fence rails, Guernsey, Rev. T. Salwey. 
The Guernsey specimens exhibit longitudinal as well as trans- 
verse septa, and are more transparent. They differ in no other 
respect, the proportions of the constituent parts being precisely 
the same. Mr. Salwey writes that the tufts are green when fresh. 
We have specimens from Upper Carolina in which the threads 
are still more opake than in those from Ohio. 
SPOROSCHISMA, N. g. 
Flocci erecti simplices; membrana exterior inarticulata te- 
nax; endochroma demum in sporas quadriarticulatas emer- 
gentes secedens.
