Lachnea cinnabarina (Schw.) — Ascophores g-reg'arious or 

 scattered, sessile, at first subglobose, then expanded, ii-3 lines, 

 across, fleshy, |^-line thick, disc flat, scarlet, tending- to Vermillion, 

 margin obtuse, bordered by rows of subclavate cells 40-50 x 

 20-25 /x, exterior ochre, almost glabrous, only a few slightly 

 thick walled hairs being present, the basal cells give rise to a 

 few flexuous, hyaline, aseptate hyphae 7 fi thick, which penetrate 

 the substratum ; excipulum of irregularly inflated loosely inter- 

 woven, septate hyphae, regular and parallel at the cortex which 

 is 3-4 cells deep, cells 40-50 x 25-30 /x, outermost layer globose 

 30-35 fi. Asci cylindrical, base gradually narrowed into a curved 

 foot, 200-220 X 12 ju, apex subtruncate ; spores 8, obliquely 

 i-seriate, elliptical, ends obtuse, hyaline, continuous, eguttulate, 

 minutely verrucose, 15-18 X 18 /x ; paraphyses abundant, 

 septate, apex clavate, 8 /x thick, filled with red granules 3.5-4 ^ 

 thick below.

Lachnella cinnabarina S'ACC. Syl., viii., n. 1643. 



On dry, muddy settlings of old dye tanks, Hebden Bridge, 

 September, 1905. Crossland and Needham. First British 

 record. Previously recorded for America only. Closely allied 

 to L. Hfubraia, but diflFers in the distinctly but minutely verrucose 

 spores and almost glabrous exterior and margin. 



Acetic iodine turns contents of paraphyses blue-black, no 

 effect on asci. 



Lachnea gilva (Boud.) Sacc. Syl., n. 747. — Ascophores 

 scattered or gregarious, often contorted through mutual 

 pressure, sessile, at first subglobose, finally expanded, fleshy, 

 disc sometimes undulate and lobed, dingy pale reddish-ochre, 

 5-8 lines across, exterior brown, margin clothed with pale 

 yellow-brown, 6-9 septate, gradually tapering, obtuse hairs, 

 250-300 X 6-8 jx (midway), mostly in tufts of 30-40, sparse 

 below the margin ; flexuous, almost colourless, septate hyphae, 

 5-6 ju, thick spring from the basal cells ; excipulum of stout, 

 irregularly swollen hyphae, cortical cells brown, subglobose, 

 15-20 /xdiam. ; Asci cylindrical, 8 spored, 200-220 x 12-14 /^> 

 apex rounded ; spores obliquely i-seriate, hyaline, elliptical, 

 smooth, continuous, eguttulate, 16-17 ^ 9-10 /x ; paraphyses 

 hyaline, septate, 5 /x, slightly thickened upward.
