LEUCOSPORI. 121 



ground, and among moss, inodorous, single (not caespitose), pileus fuscous Mycena. 

 becoming somewhat pale, not hygrophanous, in the last species orange. 



These differ from their nearest allies the Rigipedes by their mode of growth, 

 their stature, their flaccid stem, with its very narrow tube, and their gills 

 which are scarcely connected by veins. But species with a filiform stem also 

 occur in the remaining sections, and therefore the other marks must be at- 

 tended to ; there are also slender forms among the Fragilipedes. 



VI. Lactipedes (milky -stemmed). Gills milky when broken as well as the 

 rooted, dry stem. 



VII. Glutinipedes (glutinous-stemmed). Stem juiceless, but viscous with 

 gluten. Gills at length decurrent with a tooth. Some of the species in the 

 foregoing sections, which are only slippery to the touch when moist, must be 

 duly separated from this group. 



VIII. Basipedes (stem furnished with a base). Stem dry, rootless, the base 

 naked and dilated into a disc, or strigose and swollen into a little bulb. Ten- 

 der, growing singly, becoming flaccid. 



IX. Insititiee (insero, to insert or graft). Stem very thin, inserted (i.e. 

 growing on other plants without a root or tubercle or flocci at the base), dry. 

 Gills adnate, uncinate with a small decurrent tooth (and not as in the Om- 

 phalian Integrelli truly decurrent). Very tender, becoming flaccid as soon as 

 the sun touches them. (A. roridus Fr. is the only species in the foregoing sec- 

 tions which is inserted, but it is very glutinous.) 



I. CALODONTES. Edge of gills darker, denticulate, &>c. 



248. A. pelianthinus Fr. Pileus 4 cent. (\y z in.) broad, pale 

 Purple livid, becoming pale and rather whitish when dry, diaphan- 

 ous, convex, obtuse or obsoletely umbonate, fleshy and even at the 

 disc, membranaceous and striate at the margin ; flesh of the 

 disc moderately thick, white. Stem 5-7.5 cent. (2-3 in.) long, 2-4 

 mm. (1-2 lin.) thick, fistulose, equal, sometimes incurved at the 

 base, round, slightly firm, of the same colour as the pileus but 

 paler, even, smooth wcfibrillose upwards, naked. Gills truncato- 

 adnexed, remarkably sinuate, distant, very elegantly connected by 

 a network of veins, quaternate, more than 2 mm. (i lin.) broad, 

 dark violaceous, edge remarkably black-toothed. 



Departing from the rest especially in its unusual colour ; from its more 

 fleshy, convex (not campanulate) pileus it holds a doubtful place between 

 Collybice and Mycenes. The spores are wholly white, though the colour of the 

 srills is that of PratellfB. 



Among dead leaves in woods. Uncommon. Sept. 



The edge of the gills at once distinguishes it from A. purus. M.J.B.
