272 FUNGUS-FLORA. 



teeth round the margin ; hypothecium and excipulum formed 

 of intricately interwoven hyphae, cortex similar, the hyphae 

 running out in a more or less parallel manner to form 

 the marginal teeth ; asci 8-spored ; spores 2-seriate, smooth, 

 hyaline, elongated, continuous or septate ; paraphyses absent 

 in some species.

The distinctly toothed margin of the ascophore is the 

 most eharacteristic feature of the present genus. The hypo- 

 thecium, excipulum, and cortex being entirely composed of 

 interwoven hyphae is also remarkable. In all probability 

 the spores of G. coronata will prove to be septate when quite 

 mature. C. dentata is not a typical species, and connects the 

 present genus with Mollisia.

Scattered, stipitate, closed and subglobose at first; then 

 expanding and becoming cup-shaped; glabrous except the 

 margin, which is surrounded by 12-18 elongated, slender 

 teeth, 25-40 p. long, 15-18 p. broad at the base and soon 

 narrowing down to an elongated, bristle-like spine 812 p. 

 broad, more or less incurved, and strongly so when dry; 

 pallid or with a tinge of yellow, l|-3 mm. across, teeth 

 sometimes whitish ; hypothecium and excipulum formed of 

 continuous intricately interwoven hyaline hyphae, cortex 

 similar, the hyphae running out to form the marginal teeth ; 

 stem slender, 2-3 mm. long; asci elongated, narrowly 

 cylindric-clavate, pedicel long and slender, 8-spored ; spores 

 biseriate near the tip, uniseriate below, smooth, hyaline, con- 

 tinuous, narrowly elliptical, ends acute, straight or slightly 

 curved, 15-20 X 4 p.; paraphyses slender, hyaline, not 

 thickened at the tip.
