258 FOLIICOLOUS SPHJERLE. 
27. SPHERELLA RECUTITA.  Hypophyllous. Perithecia aggregate, 
innate, slightly prominent, very minute, black, forming long parallel 
stri. Asci clavate. Sporidia linear, or narrowly fusiform with five 
septa, ‘015 mm. (0006 in.) long.—Spheria recutita, Fr. Sys. Myc. ii. 
p. 524; Berk. Eng. Fl. v. pt. ii. p. 278; Berk. Outl. p. 401.—On 
grasses. (Pl. L. Fig. 30.) Note. Not having by me an authentic 
specimen of S. recutita, the description of fruit, and figures, have been 
given from specimen published in Rabenhorst’s Fungi Eur. Exs. no. 
140, which appears to be doubtful (see * Hedwigia,’ 1865, p. 154). 
Spheria duplex, Sow., may belong to this series, but at present I 
have not had the opportunity of examining specimens 
28, SPHJERELLA LINEOLATA. Amphigenous, erumpent, with a 
brownish stroma. Perithecia very small, disposed in lines. Asci 
clavate. Sporidia oblong, with from three to five sporules or nuclei. 
'0125 mm.—Spheria lineolata, Roberge in Desm. Pl. Crypt. n. 1263; 
Berk. and Br. Ann. Nat. Hist. n. 616 ; Berk. Outl. p. 399; Cooke, 
Index, n. 2331. Spherella lineolata, De Not. Schema, p. 63.—On 
Ammophila arundinacea. (PI. L. Fig. 31.)
