366 FUNGUS-PLOKA. 



Pseudohelotium Scrupulosmn, Saco., SylL, viii. n. 1222. 

 On dead thorn, and Biibus idaeus. 



Very minute, when fully expanded more or less cylindrical, 

 margin erect and acute. 



Specimen in Karsten, Fnng. Fenn., n. 648, examined. 



Dasyseypha Bullii. Mass. 



Ascophores gregarious or sometimes clustered in small 

 ■groups, very minute, rarely measuring more than J mm. 

 across, stipitate, clavate or turbinate and closed at first, then 

 expanding until almost plane, margin often wavy, whitish, 

 stem very short, expanding upwards, brown, attached to the 

 substratum by brown, septate hyphae, 3-4 fi. thick ; sub- 

 stance very thin, excipulum parenchymatous, cortical cells 

 very narrow and elongated in the direction from stem to 

 margin, and terminating at the margin in delicate hyphae, 

 15-25 X S fjL; similar scattered hyphae springing from the 

 cortical cells cause the outside to be slightly pubescent ; asci 

 clavate, apex rather narrowed, 8-spored ; spores irregularly 

 2-seriate, hyaline, continuous, narrowly elliptical, ends rather 

 pointed, or one end sometimes rounded, 6-8 x 1 ' 5 /a para- 

 physes slender, hj'aline, apex very slightly clavate.

Mollisia Bullii, Phil., Brit, Disc, p. 194, pi. 6, f. 35. 



Pseudohelotium Bullii, Sacc. Syll., viii. n. 1218. 



On a wooden cistern. 



Authentic specimen from author examined. 



The present species cannot hQ&Mollisia; the pilose exterior 

 and very short stem gradually expanding into the turbinate 

 ascophore, as also the structure of the excipulum, point to 

 Dasyseypha, of which it must be considered as a degraded 

 form. It is at the same time closely allied to such species of 

 Mollisia as M. mali, and may be looked upon as connecting 

 Mollisia and Dasyseypha. 



Dasyseypha elaphines. Mass. 



Gregarious, sessile, base somewhat narrowed, subglobose and 



closed, then expanding and becomiiig saucer-shaped ; disc 



pale grey, externally pale buff, margin paler, everywhere 



covered with cylindrical, septate, obtuse, somewhat flexuous
