A NEW COPRINUS. 



THOMAS GIBBS. 

 Witkswoitli. 



CoPRiNUS CORDISPORUS, Gibbs, n. sp. 



Pileus at first cylindric-ovate," then expanded, at length 

 upturned, very thin, phcate-sulcate, sphtting along the backs 

 of the gills, margin crenate, 6-9 mm.' across, whitish or pallid 

 ochraceous, disc sprinkled wdth tawny furfuraceous papillae. 

 Gills free, but ending close to the stem, rather narrow, 25-30 

 in number in the larger pilei, intermediate shorter ones few or 

 none. Stem 2 cm. long, filiform, hollow, whitish-hyaline^ 

 glabrous except at the base, which is slightly thickened and 

 densely strigose-squamulose. Spores dark brown purple, 

 laterally compressed, front view- obtusely cordate 9-10 f^. 

 diameter, side view elliptical, 5-6 /x, thick, Cystidia cylindric- 

 fusiform 50 x 10 



On dung of Horse, Sheep, Rabbit, etc, Sheffield, Farnley 

 Tyas and Buckden, West Yorkshire ; Wirks worth, Derbyshire. 



This pretty little species was first found by me in April 

 1904, near Sheffield. In April 1906, it turned up in this 

 (Wirksworth) district, and since that date I have had it more 

 or less constantly under observation. The features whick 

 specially distinguish it from other nearly related small species 

 are the persistent furfuraceous papillse on the disc, the densely 

 squamulose foot, and the obtusely heart-shaped compressed 

 spores. 



Sometimes the squamulose area at the foot of the stem 

 ends definitely in a sort of strigose ring.
