Patinella olivacea. Sacc., Syll., viii. n! 3167. 



Gregarious, sessile, applanate, at first circular and with a 

 distinct, entire, tumid margin of a greenish-yellow colour; 

 disc even, dingy olive-green then blackish ; during growth 

 the outline often becomes more or less irregular and lobed ; 

 externally blackish, rugulose; excipulum parenchymatous, 

 cells large, very irregular in form, dark, towards the 

 exterior forming parallel, densely packed, cylindric-clavate, 

 3-4-septate, obtuse hairs, 30-50 X 8-10 ju. ; numerous stout, 

 septate, coloured hyphae are given off from the cells of the 

 excipulum near its base ; a dingy purple-red colouring 

 matter is liberated from the tissue of the excipulum when 

 treated with dilute potassic hydrate ; asci narrowly cylin- 

 drical, apex rounded, 8-spored ; spores obliquely uniseriate, 

 elliptic-oblong or sometimes with a tendency to become 

 clavate, continuous (perhaps becoming 1-septate), smooth, 

 2-guttulate, with an olive or bluish-green tinge, 9-12 x 

 4-5 p.; paraphyses filiform, septate, often forked near the 

 base, 1 5-2 p thick, apex clavate, colourless.

On old wood. 



I should consider the spores to be hyaline under normal 

 conditions, the bluish or purplish tinge being a stain derived 

 from the colouring matter present in the excipulum ; the 

 asci are sometimes also stained. Spores constantly con- 

 tinuous in every specimen examined. 



The type specimen of every species given as a synonym 

 has been examined.
