GEOPYXIS. 377 



glabrous ; stem usually slender, often tapering at the base 

 and rooting, not longitudinally grooved or lacunose ; asci 

 cylindrical, 8-spored ; spores obliquely 1-seiiate, hyaline, 

 continuous, elongated; paraphyses present.

Growing on the ground or among dead leaves, rarely on 

 wood. 



The leading characters of the genus as here understood are : 

 ascophore large, never less than 1 cm. across, stipitate ; stem 

 even, that is not grooved or lacunose. In Dasyscypha the 

 ascophore is always much smaller, rarely more than 12 mm. 

 across, the exterior more distinctly pilose, and the stem very 

 short or absent. Acetabula differs in the stout, grooved or 

 lacunose stem ; finally the species of Sclerotinia agree in the 

 more or less elongated, slender stem, but differ in being 

 absolutely glabrous, and in springing from a sclerotium. 



* Externally tomentose or downy. 



Geopyxis majalis. Sacc., Syll., viii. n. 247. 



Scattered, stipitate, margin incurved and closed when 

 young, then expanded and cup -shaped, narrowed down- 

 wards into the short, stout stem, rather fleshy, up to | cm. 

 broad; disc orange-yellow, externally and the stem white 

 and minutely downy; cortex parenchymatous, cells irregularly 

 polygonal, 56 p. diameter ; asci cylindrical, apex narrowed, 

 8-spored ; spores smooth, continuous, hyaline, elliptical, ends 

 rather acute, 10-12 x 6 /*, obliquely 1-seriate ; paraphyses 

 very slender, cylindrical, hyaline.

The above description is drawn up from a specimen in

Geopyxis coccinea. Mass. 



Scattered or in groups of 2-3 specimens, stipitate ; at first 

 closed, then expanding and becoming shallowly cup-shaped,
