NEW OR CRITICAL BRITISH FUNGI. 
41 
Copxinus umbrinus, Cke. Sf Mass. 
Pileus at first conico-hemispherical, then almost plane, finally 
splitting at the margin and revolute, 1-lf in. across, dark umber, 
coarsely sulcate up to the disc. There is usually a large white patch 
of the primary veil persistent at the apex, the remainder with 
scattered, snow-white, floccose scales ; flesh exceedingly thin, 
umber ; gills free, distant from the stem, crowded, 1^ line broad, 
thin, becoming black, margin persistently white ; stem 4-6 in. long, 
3-4 lines thick below, slightly and gradually attenuated upwards, 
hollow, dark umber from the first, polished and shining, base 
bulbous, solid, slightly rooting, sheathed with the persistent white 
volva, the free margin of which is reflexed about |in. from the 
base ; basidia cylindrical, attenuated downwards into a very narrow 
base, apex truncate, 35-40 X 14-15 fx ; spores sooty-black, elliptic- 
oblong, obliquely apiculate; 17-18 x 9 /i ; cystidia absent. 
On manured ground. Kew. 
Distinguished from every other volvate species of Coprinus by 
the umber-coloured stem. When quite young the entire fungus 
is enclosed in a snow- white volva. 
Coprinus oblectus, Fries (=Agaricus oblectas, Bolton t. 142). 
Not seen since Bolton’s time until recently collected in quantity 
by Mr. C. Crossland, at Halifax, Bolton’s original locality. The 
figure by Bolton, t. 142, and reproduced in Cooke’s Illustr. t. 661, 
is very characteristic. Basidia broadly spathuliform, truncate ; 
spores elliptic-oblong with an oblique basal point, 16 x 8-9 jx. 
DLactazius latezitioroseus, Karsten Medd. ad Soc. pro Faun, et FI or. 
Fennica , 1888-91, jp. 15; emend, p. 20. 
Pileus up to 11 c.m. broad, convex with an umbilicus, soon 
depressed, often at length somewhat infun dibuliform and wavy, 
often unequal, zoneless or rarely slightly zoned, flesh up to 1 c.m. 
thick, becoming very thin towards the margin, dry, becoming 
broken up at the disc into minute, granite-like squamules, scales 
larger towards the margin, and disappearing eventually, flesh- 
colour or brick-red with a rosy tinge, becoming pale ; gills de- 
current, rather distant, thin, up to 5 m.m. broad, often furcate and 
connected by veins, becoming yellowish ; stem up to 7 c.m. long 
and 2 c.m. thick, stuffed, sometimes becoming hollow at the base ; 
unequal, incrassated at the base, curved or flexuous, rarely straight, 
very slightly flocculose, colour of the pileus or paler; spores sub- 
globose, echinulate, uniguttulate, white, 8-9 x 6-8 /x ; milk acrid, 
white. 
In woods. 
The British specimen measured 3^in. across the pileus ; stem, 
3in. long, lin. thick.
