314 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPH^RI^. 



Div. 25. SuBTECT^. — Perithecia innate, covered, at length erumpent, concrete with the matrix, 



often without a prominent ostiolum. 

 Div. 26. Caulicol^. — Perithecia subinnate, at first covered, at length exposed by the separation 



of the epidermis, discrete from the matrix. 

 Div. 27. FoLiicoLiE. — Perithecia innate, covered, connate with the matrix, very rarely erumpent 



or free. 

 Div. 28. Depazea. — Perithecia simple, innate, seated on an arid spot on leaves which are still 



green. 



Div. 17. Btssised^. 



215. S. Glis, Berkel. and Currey MS. Tab. LVII. fig. 1, ascus with sporidia, x 220. 

 Sporidia biseriate, pale brown, simple, slightly curved, 0-0009 to 0-001 inch long, 

 rounded at each end. Perithecia rather large, round and very flat, seated on a dense 

 subiculuni, usually entirely hidden beneath the bark, not erumpent, but raising the 

 bark into smooth, rounded, or elongated swellings ; the perithecia and subiculum 

 are usually of a dark dirty green tinge. I do not know where to classify this plant, 

 if not with the Byssisedce, although it is quite anomalous to find a Sphwria of this 

 division entirely hidden by the bark. The presence of the fungus is only indicated 

 by the smooth swelling of the small branches of oak, on which it occurs. The wood 

 of these branches is generally somewhat decayed. The Sphceria is common in the 

 neighbourhood of Weybridge, and I have also found it near Tunbridge. It grows, as 

 far as I know, only on oak, and I am not aware that it has been hitherto described. 

 Some of my correspondents have received it from me under the manuscript name of 

 S. tmnentosa ; but Mr. Berkeley, to whom I sent it at first without a name, marked 

 it in his herbarium as Sphairia Glis, and at his request I have adopted that name.
