862 SPH^RIACEI. 



AscopnoRE. — Peritliccia produced amongst the conidiophorous 

 threads, numerous, black, shining, globose, scarcely papillate ; 

 asci linear-clavate ; sporidia straight, oblong-lanceolate, pellucid, 

 with two or three nucleoli, at length biseptate. — B. ^ Br. Outl.

On wood. 

 Sporidia "013 m.m. long, *004 m.m. thick. 



2579. Spheeria botryosa. Fr. *' Granular Sphasria." 



Csespitose or conglomerated, rounded ; perithecia globose, 

 connate, rugose, 02:>aque, black, depressed at the apex ; asci 

 clavate, containing an indefinite number of very minute gran- 

 ules. — Fr. S.M. \i.p. 342, Fries, exs. no. 112. Curr. Linn. Trans.

 Germ. p. 34. Fckl. Sym. Myc.p. 234. 



" Granules colourless, about ('0001 in.) '0025 m.m., endowed with Brownian 

 motion. I should have doubted these granules being true sporidia, but I 

 find this fruit coinciding exactly with that of authentic specimens from the 

 Scleromycetes suecice. Fries considers the plant a Sphct;ria, with confluent peri- 

 thecia, but not an Hypoxylon." — F.C Nitschke calls the sporidia ovate, ob- 

 tuse, unequilateral. 



2580. Spheeria pomiformis. Pers. " Apple- shaped Sphseria." 



Rather small, black ; perithecia apple-shaped, even, with an 

 impressed ring round the papilleeform ostiolum ; sporidia ovate, 

 or ovate-oblong, obtuse, bilocular, slightly constricted, hyaline, 

 or pale brown.— P^rs. Syn.p. 65. Ic. Pict. t. b,f. 4, 5. Moug. exs.

On dead wood. [Low. Carolina.] 



Perithecia globose, rather thin, but slightly rigid, and in consequence 

 collapsed only at the apex. 



2581. Sphaexia rhytidodes. B. ^ Br. " Sulcata Sph^ria." 



Gregarious, black ; perithecia seated on a spot-like mycelium, 

 subglobose, rugoso-sulcate ; ostiola papill^form ; asci elongated ; 

 sporidia biseriate 3-6 septate, torulose. — B. ^* Br. Ann. N.H. no. 

 873, MO,/. 21. 



On ash pollards. Jan. Batheaston. 



Mycelium black, forming dark stains, on which are seated subglobose, 

 laterally sulcate perithecia, with a papillseform ostiolum. Asci elongato- 

 clavate. Sporidia biseriate ("OOl-'OOlS in.) •025-*03 m.m. long, cymbiform.
