Scattered or gregarious, sessile, subgloljose and closed at

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

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

 liypothecium and excipulmn minutely parenchymatous, 

 cortical cells irregularly polygonal, running out in irregular 

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

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

 rough with minute particles of lime ; asci clavate, pedicel 

 long, slender, apex narrowed, 8-spored ; si^ores obliquely 

 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 Orhilia, probably 0. leucostigma.
