SPH^EIACEI. 895 



2688. Sphaeria hyphenis. Coolie. " Hyphen Fern Sphaeria." 



Forming: short parallel lines ; perithecia minute, subglobose, 

 raising and at length cracking the cuticle, black, in short lines ; 

 ostiola acute, sometimes piercing the cuticle ; sporidia biseriate, 

 or clustered, elliptic, uniseptate, slightly constricted, the upper 

 cell somewhat swollen, hyaline. 



On stems of Pteris aquilina. May. Shere. (Dr. C.) 



Easily confounded with small forms of Dothidea ftlicina, but the lines are 

 less distinct, and, on removing the cuticle the perithecia are decided. Quite 

 distinct from S.pantherina, to which it is allied. 



2689. Sphaeria pantherina. Berk. " Panther- spot Sphteria." 



Spot-like, bounded by a flexuous, subelliptic line ; perithecia 

 immersed, furnished with a long neck and slightly prominent os- 

 tiolum ; asci lanceolate ; sporidia oblong, subfusiform, with two 

 or more obscure septa. — Berk.exs. no. 34. Mag. Zool. ^' Bot.no.

On Pteris aquilina. 



At first sight resembling S. pardalota. It differs, however, in the immersed 

 p*^rithecia and the elongated neck. The line is not always visible externally, 

 but it may always be found on making a transverse section, being in fact the 

 edge of a true conceptaculum. When the line is visible externally the cuticle 

 is nearly unaltered, when, on the contrary, it is obscure the cuticle has a 

 brown burnt appearance. — M. J. B. 



The stylospores of this species are fusiform and extremely narrow, *0008- 

 '001 in. long (see Curr. Linn. Tram, xxii./j. 285). 



2690. Sphaeria pardalota. Mont, " Leopard-spot Sphsria." 



Spot-like, limited by a flexuous line, covered by the cinereous 

 cuticle ; perithecia scattered, hemisphserico- compressed, black ; 

 stroma cinereous, incumbent, soon rimosely erumpent ; asci cla- 

 yate ; sporidia fusiform, biseptate. — Mont. Ann. Sc. JVat. i. p.

 Zool. ^. Bot. no. 99. Diaporthe pardalota, Fckl. Sym. Myc.p. 206. 



On dead stems of Convallaria multijlora. 



The stylospores of this species are colourless, rather narrowly elliptical 

 (•0002-'00U4 in.) 'OOS'-Ol m.m. long (see Curr. Linn. Tram. xxii. p. 285). 



2691. Sphaeria ceuthosporoides. Berk. "Two-faced 



Sphaeria." 



Stroma formed of the parenchyma of the matrix, suborbicular, 

 reddish-brown, circumscribed by a narrow distinct black line 

 penetrating the leaf; perithecia 6-10 scattered, covered, project- 

 ing on either surface, their apices seated on the upper surface of
