LEUCOSPORI. 63 



whitish ; flesh becoming fuscous. Gills easily separating from the Tricholoma. 

 hymenophore, rounded-free, crowded, broad, 4-6 mm. (2-3 lin.), 

 fragile, white then becoming cinereous, darker than the pileus. 



Very various in stature. Gregarious. The stem is sheathed at the base in a 

 peculiar manner with the floccose, compact, white mycelium. It might perhaps 

 be regarded as a species of Paxillus, on account of the gills easily separating 

 from the hymenophore. 



In woods. Frequent. Aug. 



Smell rather disagreeable, pungent ; the stem, however, when broken smells 

 like new meal. B. & Br. Spores 5 mk. ll'.P. Name cinis, ashes. Be-

 cinereous-fuliginous, variegated with grey-pruinose spots and often 

 guttate, fleshy, not thick, but firm, convex then becoming plane or

 centric, even; flesh alike of the pileus and stem spongy, absorb- 

 ing moisture, 'white when dry, but the pileus by no means hygro- 

 phanous. Stem 2.5 cent, (i in.) or little more long, 12 mm. 

 (/4 in.) thick, solid, tough, clastic, externally fibrous, internally 

 spongy, smooth, naked, unpolished, whitish-grey. Gills emargi- 

 nate or rounded, at length somewhat decurrent when the pileus 

 is depressed, very crowded, quite entire, plane, 4 mm. (2 lin.) broad,
