210 FUNGUS-FLOKA. 



Peziza mercurialis, Fckl., Fung. Rhen., n. 1593. 



Mollisia atrata, var. mercurialis, Phil., Brit. Disc., p. 183. 



On dead stems of mercury (Mercurialis pcrennis) 



Specimen examined in Fuckel's Fung. Rhen., n. 1503, and 

 Phil., Elv. Brit, n. 1 80. 



Closely allied to M. atrata ; differing more especially in 

 the margin and exterior of the ascophore, the structure of 

 which leans towards Dasyscyplia. 



Mollisia teucrii. Phil., Brit. Disc., p. 176. 



Gregarious or crowded and sometimes several specimens 

 run into each other, sessile, translucent, white with a tinge 

 of yellow or ochre, soon plane, the margin very delicately 

 pruinose at first; excipulum parenchymatous, cortical cell* 

 almost colourless, polygonal and about 7 /x diameter near the 

 base, becoming narrower upwards and running out into 

 rows of parallel septate hyphae at the margin; },-! mm. 

 across ; pale yellow and almost transparent when dry ; asci 

 narrowly clavate, apex narrowed, pedicel short, slender, 

 8-spored ; spores irregularly 2-seriate, hyaline narrowly 

 cylindrical, ends rather pointed, usually slightly curved, 

 8 x I '5-2 /JL; paraph} ses slender, hyaline, tips very slightly 

 thickened. 



Niptera teucrii, Fckl., S.ymb. Myc., App., i. p. 47. 



Pseudohelotium teucrii, Sacc., Syll., viii. n. 1228. 



On dead stems of Teucrium scorodonia. 



The appearance of the fungus under a lens suggests the 

 genus Calloria, and it becomes very thin, and almost trans- 

 parent, retaining its pale colour when dry. The above 

 description is drawn up from specimens in Fuckel's Fung. 

 Rhen., n. 2378 with which Rohm's Ascom. n. 757 is 

 identical. 1 am not certain that Phillips had the right 

 fungus in view ; his own remarks " when dry nearly black : 

 asci with a subglobose base," do not agree with Fuckel's 

 specimens. Unfortunately I cannot find ascophores in either 

 of the two sets of Phil.'s Elv. Brit., n. 177, said to bo tho 

 present species. 



Mollisia urticicola. Phil., Brit. Disc., p. 177 ; Sacc. 

 Syll., viii. n. 134]. 



Gregarious, sessile, at first globose and closed, final ly 

 becoming almost plane, glabrous ; disc greyish or pale
