asci scarcely stipitate, cylindrical ; sporidia biseriate, lanceolate, 

 sometimes curved, multinucleate, hyaline ; paraphyses filiform, not 

 thickened at the tips. Coryne purpurea, Fckl. Sym. Myc., p. 284. 

 Fckl. Fungi Bhen., No. 1136. 



On rotten wood. Epping. 



Sporidia ("0007 in.) -02 m.m. long, whereas in B. sarcoides they 

 are only half that length. The cups exceed 1 inch in diameter. 



Dothidea filicina. Fr. Cooke's "Handbook of British Fungi," 

 No. 2427. 



The description of the fruit in the work above quoted is erro- 

 neous, as I find upon re- examination. It should be as follows : — 



Asci elliptical ; sporidia biseriate, broadly fusiform, straight or 

 curved, 3-5 septate, constricted, with a short apiculus at either end, 

 amber- coloured, -0014 in. long. 



Nectria citrino-aurantia. Leer. 



Caespitose, pale orange ; perithecia very minute. — Leer, in Desm. 

 exs. it., No. 778. Rabh. Fung. Eur., No. 325. Tul. Sel. Fung.

On sticks. Batheaston (C. E. Broome). 



Remarkable for the exceedingly minute perithecia. 

 Sphaeria (Pertusae) paedida. B. $. Br. 



Perithecia ovate, rugose, opaque, free, brownish- black ; ostiolum 

 conical, at length deciduous ; asci linear ; sporidia uniseriate, con- 

 tracted in the middle.— 5. £ Br. Ann. N. H. } No. 1396, pi. x., 

 /. 13. 



On beech. April. 



Quite superficial, confluent ; sporidia -0005--0006 in. X -0002- 

 '0003 in.

 Sphaeria (macrospora) Scirpi. Fckl. (Grevillea, ii.,p. 48.) 



On Typha. May. 



Sphaeria (Immexsae) nigxofactae. Cooke. 



Gregarious, on blackened spots. Perithecia globose, opaque 

 black, rough, immersed or semi-immersed, ostiola thick, prominent, 

 sometimes alone appearing above the surface of the matrix ; asci 

 cylindrical, tetra^porous, sporidia linear, multiseptate, yellowish. 

 Paraphyses slender, hyaline, simple. 



On old cabbage stems. Eastbourne (C. J. Muller). April. 



Allied to Sphceria bacillata, C, but perithecia nearly double the 

 size, the sporidia are not much more than half as long (-0045 in.) 

 and appear to be always limited to four in an ascus. 

 Schizotuyrium. Desm. 



Perithecia sessile, simple, rather fleshy, rounded or ovate, flat- 

 tened or slightly convex, minute, punctilorm, dehiscing by a longi- 

 tudinal fissure; nucleus gelatinous; asci fixed, erect; sporidia 

 ovoid. — Desm. Ann. Set. Nat. (1849), xi., 360. 



Schizothyxium Ftazxnicae. Desm. 

 Innate, black, somewhat shining, rounded or ovate. Asci cylin-
