PATINELLA. Sacc. (figs. 32-35, p. 91.) 



Ascophore minute, sessile, scutellate or applanate, circular, 

 or irregular, rarely elongated, furnished with a parenchy- 

 matous excipuluni which forms a delicate margin ; black or 

 dark-coloured ; asci clavate, apex rounded and thick- 

 walled, 8-spored ; spores elongated, hyaline, continuous, not 

 guttulate, irregularly 2-seriate; paraphyses septate, apex 

 coloured.

Patellaria, of many authors. 



The hyaline, continuous, biseriate spores and patellate 

 ascophore characterise the present genus. 



Patinella rubro-tingens. Sacc, Syll., viii. n. 3182. 

 Usually densely crowded and forming long narrow 

 blackish streaks 2-3 cm. long, rarely scattered towards the 

 ends of the groups; ascophore circular or usually irregular 

 from mutual pressure, sessile, rather fleshy, at first closed, 

 then gradually expanding, black, minutely wrinkled outside, 

 otherwise glabrous ; margin with a reddish tinge, irregular, 

 remaining slightly incurved, 1-1 '5 mm. diameter; ex- 

 cipulum compact, grumous, indistinctly parenchymatous ; 

 asci narrowly clavate, 8-spored; spores 2-seriate, narrowly
