Massee and Crossland : New British Discomycetes. 181 



across ; disc pale reddish-white, outside smooth, yellowish or 

 brownish; asci cylindric-clavate, apex slightly narrowed, plug- 

 blue with iodine, 50-60x9-10 /x ; spores 8, irregularly 2-seriate, 

 narrowly elliptical, ends obtuse, straight, hyaline, continuous, 

 9-12x3 /x ; paraphyses filiform, cortical cells subcircular, tinged 

 brown, becoming smaller towards the margin, where they run 

 out into rows of short, parallel cells. 



On fallen decaying birch leaves, Hebden Bridge (J. Needham). 



Although the asci and spores in our specimens are rather 

 smaller than in Rehm's, there is no doubt as to the identity 

 of the species. Rehm's asci are 50-60x9-10 /x, and spores 

 9-12x3 /x. Saccardo gives them as 56x8 /x and 8-10x3 /x 

 respectively. In the Hebden Bridge specimens the asci are 

 40-45 x 6-7 /x, spores 8-10 x 2*5 /x, occasionally approaching 3 /x.

 On decaying fern stipes, High Greenwood, Heptonstall, 

 near Halifax. 



In the British specimens the exterior of the ascophore is 

 minutely reticulated with black ridges. 



Belonidium Clarkei Mass. & Crossl. (sp. now). Figs. 1-6, PI. 1. 



Gregarious, sessile on a broad base, pulvinate or convex, 

 margin not in the least raised, pale yellowish-green, soft, up 

 to 1 mm. across ; asci clavate, apex rounded, not blue with 

 iodine, 90 x 8 /x ; spores 8, 2-seriate, hyaline, narrowly elliptical, 

 4-guttulate, then 3-septate, slightly constricted at the septa, 

 12x3 /x ; paraphyses filiform, tips not thickened; cortex paren- 

 chymatous, cells 8-12 /x diameter. 



On damp, rotten wood, Mulgrave Woods, Whitby, Y.N.U. 

 Foray, September 1900 (A. Clarke, Huddersfield). 



A very pretty and distinct species, allied to Belonidium 

 ventosum Phil., but distinguished by the pulvinate, immarginate, 

 green ascophore and the smaller spores.
