 Sacc, Syll. VIII. n. 2146; Crossl., 'The Naturalist,' Jan. 

 1900, p. 8. 



Gregarious or scattered, very minute, Yi-Yi mm. across, 

 brown ; externally paler, even, glabrous, tawny, immarginate ; 

 disc plane or convex, at length rough with the slightly pro- 

 truding- asci ; asci clavate, octosporous, 140-170 x 13-14 /x ; 

 spores elliptical, violet, at length fuscous, longitudinally striate, 

 striae scarcely anastomosing 13-15 x 7-9 /x; paraphyses hyaline, 

 septate, 5-7 /x thick at the thickened apex, immersed in yellow 

 gluten. 



Hab. — On dogs' dung, Hebden Bridge, J. Needham. 



The spores of this species are amongst the smallest met 

 with in the genus Ascobolus ; in Boudier's specimens they 

 measured 13-15x7*9 f 4 , in ours 1 1-14 x 6*5-7 "5 \u. The asci are 

 comparatively slender for that genus, 140-170 x 13-14 /x Boudier, 

 ours 140-160 x 1 2-13 /x ; as a consequence the spores remain 

 uniseriate until ejected, which is unusual in Ascobolus. 



The cortical cells are horizontally elongated, elliptical, 

 16-24 x 12-16 /x.

 or minutely papillose, grey-brown below, shading off to pale 

 cinereous at the margin, disc dark watery cinerous ; asci cylindric- 

 clavate, 40-50 x 5 /x, apex narrowed and rounded ; spores eight, 

 obliquely biseriate, elliptic-fusiform, or approaching clavate, 

 8-10x2 /X. 



Hab. — On under surface of decaying oak leaves ; mostly 

 on the nerves. Hebden Bridge, J. Needham.

 first, then becoming plane with a delicate border, up to 0*5 mm.
