and again incrassatecl^ consisting of numerous slightly constricted 

 oblong joints ; endochrome containing a single nucleus. 



Resembling somewhat in structure T. stilbosporoides, Corda, 

 of which we have an authentic specimen^ but differing greatly in 

 habit.

b. sphmaeformis, Berk. & Br. On dead stems of herbaceous 

 plants, Apethorpe. On decorticated branches of Pinus sijlvestris, 

 Wraxall, Som. 



Our specimens exhibit rather a different form from that figured 

 by Corda. Instead of being widely diffused they present little 

 Sph[eria-like 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 hie 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. Each endochrome has usually a single nucleus. 



A very curious species, distinguished from most Torulce 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- 

 v^erse 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.
