22. STENOCYBE Xyl. Bot. Not. 1854, p. 84, ^.r Stiz. St. Gall. 

 Xat. Ges. (1876) p. 196. — Thallus 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 C'alicium by the surface of the capitulum, wliich is 

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

 more slender and shorter paraphyses. The absence of a maztediura 

 entitles it to rank as a distinct genus, as originally proposed bv Xvlander, 

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

 and inconspicuous.

 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-o-7-sep- 

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

 11 mm. thick; paraphyses thin, 

 crowded. — CaJiciinn ei'sporum

This has hithei-to been confoun- 

 ded by British authors (foUowini^ 

 Mudd) with <S'. trajecta. From this 

 it is distinguished by the smaller 

 and more scattered apothecia and 

 especially by the smaller spores.
