On various kinds of dead herbaceous stems. 



Specimens examined in Cooke, Fung. Brit., exs., n. 379, 

 and Fuck el's Fung. Rhen., n. 1183. 



Readily distinguished from C. peristomalis by the bristle - 

 like marginal teeth, which are incurved when dry. 



Cyathicula petiolorum. Sacc., Syll., viii. n. 1273. 



Ascophore stipitate, scattered or solitar}', closed at first, then 

 concave, finally plane, margin minutely toothed, glabrous; 

 disc yellowish brown or tawny, externally except the margin 

 paler, 1-2 5 mm. across ; stem slender 2-6 mm. long, smooth ; 

 hy pothecium tinged brown ; cortex composed of slightly wavy, 

 septate hypliae that radiate from base to margin, where they 

 become free, tinged brown, obtuse, or inclined to clavate, 

 septate, and form the irregularly triangular marginal teeth ; 

 asci subcylindrical, apex slightly narrowed, 8-spored ; spores 

 usually 1-seriate, hyaline, continuous, narrowly cylindric- 

 oblong or sausage-shaped, rather strongly curved, 16-18 X 4/x; 

 paraphyses hyaline, about 2 p. thick, apex only very slightly

 1158. 



Hymenoscypha petiolorum, Phil., Brit. Disc., p. 132. 



On petioles of fallen beech and oak leaves. 



The margin is furnished with minute, somewhat triangular 

 teeth, easily overlooked in dried specimens. (Phil.} 



Specimen sent by Eoberge to Berkeley, and now in Herb. 

 Kew., examined; also specimen in Desm., Cr. Fr., ed. i. 

 n. 1158. 



Readily distinguished from C. coronata by the broadly 

 triangular teeth, which are formed of rather stout, septate, 

 more or less clavate hyphae. 



Cyathicula peristomalis. Sacc., Syll., viii. n. 1284. 

 Ascophores subcylindrical, base somewhat narrowed, solid, 

 glabrous except the margin, which is surrounded by 10-18 

 spreading, white, acuminate teeth, 25-35 long, by 8-10 /JL 

 broad at the base ; whitish, disc plane, about i mm. high 

 by mm. broad ; hypotheciuin and excipulum composed of 

 aseptate, hyaline hyphae very intricately interwoven, the 

 cortex is similar, and the hyphae run out to form the marginal 

 teeth ; asci fusoid, apex narrowed, widest portion sometime s
