matrix tinged -with rose-colour. Asci clavate, sporidia fusiform, 

 multinucleate. — Berk, <J- Br. Ann. Nat. Hist., No. 1334,*. xxi., /. 29. 

 On dead decorticated branches. Apr. 



Perithecia fragile, for the most part compressed and elongated, 

 so as to approximate Pertusse and Microstoma. The subjacent 

 wood is tinged throughout with magenta pink. Sporidia with 

 several nuclei (-001 in.) -02") m.m. long. 



Sphaeria (Obtectae) mammillana. Fr. " Teat-like Sphaeria." 



Scattered. Perithecia hemispherical, rather prominent, covered by 

 the blackened adnate cuticle ; ostiola papillseform. Asci cylin- 

 drical ; sporidia uniseriate, or biscriate, cylindrical, obtuse, brown. 

 —Fries Si/s. Myc. ii., 487. 



On oak twigs. Castle Rising. (C. B. Plowriglit.) 



Allied to Sphceria clypeata, N., with which it is associated by 

 some authors. Sporidia very variable in length, sometimes pseudo- 

 septate (-0008--001 in.) '02- -025 m.m. long. 



Ceratostoma Helvellae. Cooke. " Peziza Ceratostoma." 



Perithecia soft, membranaceous, ovate, smooth, pale brown, at 

 first semi-immersed ; neck scarcely equal in length to the diameter 

 of the perithecia, ending in a somewhat erect fringe of hairs. Asci 

 clavate, fasciculate, soon disappearing. (Sporidia lemon-shaped, 

 simple, dark-brown ; epispore smooth. 

 On the hjmeniumof Peziza hemnpherica. Eastbourne. (C.J.Muller.) 



Sporidia -OOOO-'OOOl in. long, about two-thirds as broad. This 

 belongs to Corda's genus M elanospora, which seems scarcely 

 capable of separation from Ceratostoma of Fries. 



Venturia atramentaxia. Choke. u Inky spot Ventnria." 



Hypophyllous, gregarious, forming irregular patches upon dis- 

 coloured spots. Perithecia subglobose, clad with short, dense, 

 patent hairs, black. Asci cylindrical ; sporidia uniseriate, elliptic 

 (probably septate when mature). — Scottish Naturalist, March, 1872.

 On living leaves of Vaccinium uliginosum. Lochnagar. (Dr.B. White.) 



Differs from Ventnria myrtilli in the larger perithecia, gregarious 

 habit, and shorter and denser hairs, as well as in other particulars. 

 Capnodium salicinum. ''Willow Capnodium." 



Forming a thin velvety black stratum; mycelium moniliform, 

 the articulations containing asingle nucleus. Peridia rather short, 

 often obtuse, but sometimes lageniform and acuminate; sparingly 

 forked, sometimes fringed. Asci broad, obtuse ; sporidia oblong, 

 Blightly curved or oblique, oblong, triseptate, with one or two lon- 

 gitudinal septa, constricted at the articulations. — Mont. Ann. Nat.
