22. STENOCYBE Nyl. Bot. Not. 1854, p. 84, ex Stiz. St. Gall. 

 Nat. Ges. (1876) p. 196. ThaUus macular, thin, usually obsolete, 

 or probably none proper. Apothecia stipitate, scattered, black, the 

 capitulum turbinato-clavate ; paraphyses slender, short ; sporal mass 

 none ; spores oblongo-fusiform, normally 3-septate, dark-brown or 

 blackish ; hymenial gelatine pale-bluish with iodine. Spermogones 

 not rightly known. 



Distinguished from Calicium by the surface of the capitulum, which is 

 without any accumulated sporal mass, the pluriseptate spores, and the 

 more slender aud shorter paraphyses. The absence of a mazsedium 

 entitles it to rank as a distinct genus, as originally proposed by Nylander, 

 a position to which he has again restored it. All the plants are minute 

 and inconspicuous. 



1. S. euspora Nyl. ex Cromb. 

 Journ. Bot. 1882, p. 272. Thal- 

 lus scarcely any proper, or very 

 diffuse and obsolete. Apothecia 

 distantly scattered, very small, 

 black ; stipes slender ; capitu- 

 lum clavate ; spores 3-5-7-sep- 

 tate, 0,018-36 mm. long, 0,007- 

 11 mm. thick; paraphyses thin, 

 crowded. Calicium eusporum 

 Nyl. Bull. Soc. Bot. Fr. xv. 

 (1856) p. 549; Carroll, Journ. 

 Bot. 1865, p. 287, pro parte. 

 Stenocybe major Nyl. Bot. Not. 

 1854, p. 84 (nomeu ineptum). 



This has hitherto been confoun- 

 ded by British authors (following 

 Mudd) with S. trajecta. From this 

 it is distinguished by the smaller 

 and more scattered apothecia and 

 especially by the smaller spores.
