 5-7 X 3-4 fj. ; asci small, apex slightly narrowed, base short, 

 stout, 8-spored ; spores 2-seriate hyaline, smooth, continuous,

Lachnella acuum, Phil., Brit. Disc, p 246. 



On fallen, decaying pine leaves. 



A very minute species, recognised by the very short, 

 iBxternal hairs, the minute spores, and the habitat. The 

 paraphyses are not 1-seriate as described by Phillips, neither 

 are the paraphyses diffluent in water, as stated by the same 

 author, but they are very difficult to see until shown up by a 

 solution of iodine. 



Specimens examined in Phil., Elv. Brit., n. 163 and 

 Fuckel, Fung. Ehen., n. 1153.

 or slightly clavate, often minutely rough, 25-35 X 3-4 /jl;
