very Barrow, running out into parallel hyphae at the margin, 

 the free portion of which measures about 25-30 x 3-4 p. ;

 spores irregularly 2-seriate, continuous, hyaline, straight

 p. 124. 



Scattered or gregarious, sessile, subglobose and closed at 

 first, then becoming hemispherical, the slightly irregular 

 margin remaining more or less erect, very thin, soft and 

 watery, whitish, or with a yellow tinge, about \ mm. diameter; 

 hypothecium and excipulum minutely parenchymatous, 

 cortical cells irregularly polygonal, running out in irregular 

 grotips to form the toothed border, and passing into parallel, 

 obtuse hyphae at the margin 25-40 x 4-5 p., sometimes 

 rough with minute particles of lime; asci clavate, pedicel 

 long, slender, apex narrowed, 8-spored ; spores obliqiiely 

 1-seriate, or 2-seriate at the apex, hyaline, continuous,

The species described by Phillips, Brit. Disc., p. 334, as 

 Calloria rubella, Pers., is certainly not the fungus intended 

 by Persoon. The specimen accepted by Phillips is from 

 " Herb. Berkeley," and the only specimen in Berkeley's 

 herbarium under the name of Peziza dentata, Pers., is an im- 

 perfectly developed Orbilia, probably 0. leucostigma.
