Rev. M. J. Berkeley on British Fungi. 207 



101. Sphceria Avellance, Schm. Myc. Heft. l.p. 64; Berk. 

 1. c. n. 182. On dead hazel leaves. King's ClirTe. A true 

 Sphaeria. The specimens given in the British Fungi are young 

 and have not perfected their asci. 



102. Sphceria Ostruthii, Fr., Obs. l.p. 174; Schm. and 

 Kz. n. 205. On Angelica sylvestris. Bungay. Mr. D. Stock. 



103. S. (Depazea) graminicola, Berk., Brit. Fung. Fasc. 3. 

 n. 186. On leaves of the harsher grasses, as Arundo Epigejos 

 and Bromus pinnatus. Apethorpe, &c. Spots oblongs pallid, 

 surrounded by a more or less distinct darker line ; perithecia 

 obscurely disposed in lines immersed. 



*104. S. (Depazed) Dianthi, A. and S. p. 47. t. 6. fig. 2. 



On Agrostemma Githago. Tansor, Norths. Sporidiaf spa- 



thulate, sometimes divided into two parts, as the spores of 



Dactylium pyriferunn, Fr., containing a few globose granules. 



Perithecia irregular conglomerate. 



Plate VII. fig. 5. a, sporidia magnified ; b, a single sporidium magnified 

 600 diameters. 



105. S. (Depazea) vagans, Fr., Syst. Myc. v. 2. p. 532. i. 

 Lamiicola, Berk. Brit. Fung. Fasc. 3. n. 188. On Lamium al- 

 bum. Oundle, Norths, where I also at the same time met with 

 the form which grows on the common mallow. 



106. Cy 'tispor 'a orbicularis, n. s. Forming orbicular patches 

 upon small orange gourds. King's ClifFe. Perithecia ex- 

 tremely thin, if indeed there be any wall distinct from the 

 cellular substance of the matrix, more or less ovate when di- 

 stinct, but in general confluent, with one or two orifices to 

 each group. Sporidia very minute, oblong, pale vinous red, 

 discharged in the form of slender tendrils. In a vertical sec- 

 tion there is an appearance of distinct perithecia, but in the 

 horizontal section this is scarcely observable. I am satisfied, 

 however, that in any case it is much better referred to Cyti- 

 spora than Ncemaspora. 



Plate VII. fig. 6. a, Cyt. orbicularis, nat. size ; b, vertical section; c, 

 horizontal section ; d, sporidia, all highly magnified. 



-}• The bodies of which the tendrils are composed are very variable, a cir- 

 cumstance which induces me to call them sporidia rather than asci. Fries's 

 rule is well worth attending to, that " sporidia either arise from conidia or 

 are separated from flocci or asci. The form of the former is variable, of the 

 latter constant."
