Massee and Cross land : New British Discomycetes. 183 



Readily distinguished among the red species of Lachnea by 

 the almost cylindrical and nearly colourless multiseptate, thin- 

 walled marginal hairs and the large spores. Most nearly allied 

 to L. umbrata Phill., which differs in having much smaller 

 spores and less crowded habit of growth. 



Lachnea Lojkseana Rehm, Kr. Fl. Disc, p. 1045. 



Scattered, sessile, at first globose and closed, finally almost 

 plane with an upraised margin, 3-5 mm. across ; disc dingy 

 yellowish-brown, sometimes with a flesh-coloured tinge ; ex- 

 ternally furnished with pointed, pale yellow T -brown septate hairs 

 100-150x6-8 /x ; asci cylindrical, apex obtuse; 8-spored, 180- 

 200x12-14 fx ; spores obliquely i-seriate, broadly elliptical, 

 smooth, hyaline, eguttulate, averaging 16 x 9 /x, paraphyses 

 slender, scarcely thickened at the pale-coloured tips ; cortex 

 parenchymatous, cells 15-18 /x diam., brownish.

Neottiella luteopallens Sacc, Syll. VIII., p. 191. 



On the ground, Hebden Bridge, Yorkshire. 



Allied to L. cretea ;n general structure and in the thin-walled 

 hairs, but differing in colour and other features. 



Dasyscypha inquilina Winter, in Fung. Eur. Exs., n. 2841. 



Scattered, sessile or narrowed to a stem-like base, sub- 

 globose at .first, then expanded, disc slightly concave, margin 

 raised, 1 mm. across, white, externally shortly pilose, hairs deli- 

 cate, hyaline, septate, 40-50 x 4-5 /x, apex rounded or subclavate, 

 scattered or tufted ; asci cylindric-clavate, apex narrowed, 35- 

 40 x 5 /x ; spores S, obliquely subbiseriate, hyaline, continuous, 

 eguttulate, narrowly oblong-fusiform, straight, 6-9 x 1*5-2 \x ; 

 paraphyses narrowly lanceolate, rather longer than the asci, 

 40-50x2*5-3 /x at broadest part; flesh white, very thin; hypo- 

 thecium of densely interlaced hyaline hyphae 3-4 /x thick; cortical 

 cells 10-16x4-5 /x below, shorter and broader above, narrowing 

 towards the margin. 



On Equisetum sylvaticum , Hebden Bridge, J. Needham. 



The above diagnosis is drawn up from the British specimens. 

 The ascophores are a little larger than in Continental specimens. 



Dasyscypha vitreola Massee. PI. 2, figs. 12-16. 



Gregarious, sessile, concave, becoming almost plane, sub- 

 stance very thin, watery, translucent, white, becoming more or 

 less tinged with yellow when dry, up to 0*5 mm. across ; margin 

 and for a short distance down the outside minutely pilose, 

 marginal hairs largest, 30-40x3 /x ; cortex minutely parenchy-
