over the matrix of a shining black ; giving off branches from the 

 fascicles, which are themselves fasciculate, and often confluent 

 with one anothei*. These are at times contained in a common 

 sheath, exactly as in the genus Microcoleus. They are for the 

 most part barren, but occasionally fructification is produced on 

 the edge of the fascicles, on the free-branched apices of the 

 threads. It consists of large, globose, dark spores, wliicii contain 

 a single nucleus ; from which circumstance we have called it 

 Glenospora. It is analogous to Acremonium, but that belongs 

 to the group of Mucedinece, while this belongs to Dematia — 

 resembling closely the mucedinous genus Brachycarphium^ 

 Berk., discovered in amber by Dr. Thomas, and figured in the 

 ' Annals of Natural History' for December, 1848.

It may be remarked, that Mr. Tiiwaites found a very^ similar 

 production, only with hyaline tlu-eads, mixed up with CoccocJiloris 

 Brebissotiii, growing in dripping places near Bristol. The fruc- 

 tification and the whole structure are very similar. At present 

 it has not been found by itself, so as to enable him to ascertain its 

 habit and colour when freely developed. The spores are dark- 

 brown, and have a pretty eflisct on the colourless filaments. This 

 may be called Glenospora T/iwaitesii, but we have not thought 

 it necessary to give specific characters, as we have scarcely suffi- 

 cient information for this purpose. The spores of G. Curtisii, 

 it may be observed, when viewed by transmitted ligiit, have a 

 lilac tinge, as have also the threads in portions of the stratum, 

 but not constantly.
