MOLLISIA. 217 



Mollisia fallax. Gillet, Champ. Fr. Disc., p. 119-; 

 Phil., Brit. Disc., p. 175; Sacc., Syll., viii. n. 1374. 



Gregarious or crowded, sessile, at first closed and almost 

 globose, then expanding and becoming plane and discoid, 

 margin more or less incurved when dry, disc grey then 

 brownish, externally blackish-brown, about | mm. across; 

 excipulum formed of interwoven hyphae, running out into 

 brownish pseudoparenchyma at the surface and margin ; 

 asci narrowly clavate, apex slightly narrowed, 8-spored ; 

 spores irregularly 2-seriate above, 1-seriate below, hyaline, 

 elliptic-fusiform, or the apex sometimes obtuse, continuous 

 at first, then distinctly 1-septate, 9-11 x 3 /u, ; paraphyses 

 very slender, tips not thickened, often branched. 



Peziza fallax, Desm., Ann. Sci. Nat., 1845, p. 367. 



On scales of the cones, also on branches of Scotch fir. 



Specimen in Desm., Cr. Fr., ser. i., n. 1420, examined. 



The spores are distinctly 1-septate at maturity, as stated 

 by Phillips, and I think they will prove to be 3-septate 

 when quite mature ; if so, the fungus will go into the genus 

 Belonidium. 



**** On ferns. 



Mollisia filicum. Phil., Brit. Disc., p. 19. 



Ascophore very minute, up to mm. high and as much 

 across when expanded, at first clavate, then globose and 

 substipitate, finally expanding and rcore or less funnel- 

 shaped, translucent, very thin, white or with just a tinge of 

 straw-colour, rigid and pallid when dry; excipulum con- 

 sisting of hyphae about 3 p. thick and sparsely septate, lying 

 parallel and radiating from root to margin, absolutely 

 glabrous, margin entire ; asci narrowly clavate, narrowed into 

 a long, slender base, spores 8, uniseriats, hyaline, smooth, 

 elliptic- oblong, ends rather acute, often 2-3-guttulate, 

 9-13 x 3 p.; paraphyses filiform, about 1-5 thick, apex not 

 thickened.

Pezizella filicum (Phil.), Sacc., Syll., n. 116(3. 



On dead stems of Lastraea filix-mas. 



Gregarious, very minute, almost transparent when moist. 

 Almost cylindrical when quite young, and with a minute
