102 DECADES OF FUNGI. 
This is evidently a Mycena, but the pileus is strongly umbilicate. 
The peculiar form of the gills will not allow of its being placed in Om- 
Phalia, and the nature of the stem excludes it from Pleurotus and Cli- 
tocybe, from the latter of which it is removed by its ligneous habitat. 
369. 4. (Mycena) incommiscibilis, n. s. ; pileo conico subcarnoso 
levi; carne fuliginea ; stipite elongato deorsum incrassato; lamellis 
ventricosis postice attenuatis adnatis pallido-flavis. Hook. fil., Ser. 2, 
No. 11. 
Has. In pine-woods. Sikkim, 11,000 feet. 1849. 
Dry, inodorous, brittle. Pileus scarcely $ of an inch broad, conical, 
ochraceous, scarcely striate, subcarnose. Stem 4 inches high, 13 line 
thick, incrassated below, where there are a few rooting fibres, fistulose, 
nearly white. Gills ventricose, attenuated behind, adnate, shaded with 
yellow. 
This clearly belongs to the same section with 4. metatus, but it is 
inodorous.- I cannot point out any species to which it bears a very close 
affinity. 
370. A. (Mycena) dentosus, n. s. ; pileo sicco campanulato umbonato 
pulverulento sericellove, margine striato laciniato dentato; stipite elon- 
gato deorsum incrassato; lamellis latis adnatis incarnatis acie candida 
undulata. Hook. fil., Ser. 3, No. 29. 
Has. In pine-woods. Sikkim, 11,000 feet. 
Dry, brittle; odour faint. Pileus $ of an inch broad, campanulate, 
' umbonate or subacute, greyish-green, pulverulent or slightly sericeo- 
striate. Stem 3—4 inches high, scarce a line thick, more or less curved, 
dirty white, incrassated below and tomentose, fistulose. Gills broad, 
ventricose, adnate, flesh-coloured, with a broad white margin, which is 
undulated. 
A well marked species, to which I can point out no very near ally. 
It is intermediate between the groupes Frayilipedes and Filopedes of 
Fries's ‘ Epicrisis.’ 
371. 4. (Mycena) puberulus, n. s. ; pileo late campanulato obtuso 
griseo sericello; stipite gracili deorsum incrassato; lamellis latiusculis 
postice rotundatis subliberis. Hook. fil., Ser. 2, No. 19. 
. Has. In pine-woods. Sikkim, 11,000 feet. 1849. 
Dry,inodorous; delicate.  Pileus + an inch broad, campanulate, ob- 
tuse, grey, minutely silky. Stem 2 inches high, scarce a line thick, in- 
incrassated below, downy at the base, fistulose. Gills rather broad,
