FUNGUS-FLORA. 



OCELLABIA. Tulasne. (figs. 34, 35, p. 22.) 



Ascophore with or without a distinct margin, emmpent, 

 surrounded by a torn edge formed by the bark of the host 

 .plant, when a true margin is present it is more or less 

 connate with the spurious bark margin ; disc almost plane, 

 clear - coloure d ; asci cylindric-clavate, 8-spored ; spores 

 elongated, straight or slightly curved, biseriate, smooth, 

 hyaline, continuous; paraphyses usually thickened and 

 coloured above.

Stictis, of some old authors. 



Growing on branches covered with bark, or on wood. 

 Distinguished by the spurious, irregular margin formed by 

 .the torn and raised bark, surrounding the ascophore ; when 

 a true raised margin is present, it is within, and closely 

 applied to the spurious margin ; sometimes the latter falls 

 away, leaving the true margin only, when the. fungus 

 superficially resembles a Stictis, but is distinguished by the 

 very diiferent, shorter and thicker spores. 



* Spores elliptical.

 Eehm, Krypt.-Flor., Disc., p. 134; Sacc., Syll., 2690. (figs.

Scattered, gregarious, or sometimes confluent, circular or 

 oblong, J 1 ; mm. across, globoso-depressed, erumpent, sur- 

 rounded by the torn bark, which forms a fringe, disc plane, 

 patelliform, golden-yellow then brownish, soft at first, 

 then firm ; asci cylindric-clavate, thick-walled, apex obtuse, 

 8-spored; spores biseriate, elliptic-oblong, ends obtuse, 

 straight or very slightly curved, continuous, hyaline, smooth, 

 with 1-2 large or several small guttulae, 20-30 X 10-12 p. ; 

 paraphyses filiform, septate, thickened at the summit, often 

 curved, yellow.
