DASYSCYPHA. 333 



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

 elliptical, or inclined to be clavate, 7-10 X 1*5 /x; parapkyses 

 lanceolate, acute, 5-6 /x broad at the widest part, hyaline, 

 continuous.

Lachnella bicolor, Phil., Brit. Disc, p. 249, pi. viii. f. 46. 



On dead branches of oak, hazel, hawthorn, &c. 



The bairs appear io be continuous, as a rule, when 

 examined in water, but when treated with white potassic 

 hydrate, followed by iodine, the very thick walls and septa 

 show very distinctly. Known from D. calycina and D. re- 

 sinaria in not growing on conifers. D. patula differs in the 

 very long hairs, and in growing on leaves. 



Specimens examined in Berk., Brit. Fung., n. 155, and 

 Kunze, Fung. Sel., n. 182. 



Dasyscypha patula. Sacc, Syll., viii. n. 1844. 



Gregarious ; furnished with a very short stem, clavate 

 then expanded, thin ; excipulum composed of very long, 

 narrow cells about 4 /n broad, arranged more or less parallel 

 and radiating from the stem to the margin ; externally white 

 and densely covered with long, slender, slightly wavy, 

 colourless, cylindrical, sharp pointed hairs, wall very thick 

 and the lumen almost obliterated, 70-120 x 4-5 fx, longest 

 and most numerous at the margin ; disc concave, pale yellow, 

 up to J mm. broad and high ; asci cylindric-clavate, base 

 thickish, 8-spored ; spores irregularly biseriate, slenderly 

 fusiform, 8-12 X 1*5-2 /x, hyaline, continuous; paraphyses 

 lanceolate, apex pointed, about half as long again as the 

 asci, colourless, about 4 /x thick.

Lachnum patulum, Eehm, Krypt.-Flora, Disc, p. 875. 



On dry fallen oak leaves. 



A very beautiful, but minute species, when examined in 

 the dry condition under a low power, resembling a minute 

 ball of loose floss silk. The hairs are longer, and slenderer 

 than in any other British species, slightly wavy, and more 

 or less interwoven ; the wall is very thick and the lumen — 

 central cavity — almost obliterated, hence they appear to be 

 without septa — continuous — but if treated with dilute potassic
