Ag. hematocephalus, Mont. and A. atrorubens, Berk., but is 
very distinct from either, being a much smaller species, with 
a differently coloured pileus. The stem is precisely like that 
of Ag. hematocephalus. The nearest ally amongst European 
species is, perhaps, Ag. juncicola. Ag. bambusinus, Fr. is 
too imperfectly described to form an accurate opinion as to 
its affinities. 
5. Ag. (Marasmius) mitiusculus, n. s., pileo plano-umbilicato 
albido rugoso ; stipite gracili cinereo-velutino supra incrassato 
glabrescente rufo; lamellis pallidis, acute decurrentibus, 
interstitiis plerumque levibus. 
On rootlets with the foregoing species. Minas. 
Pileus 4 of an inch broad, plane depressed and umbilicate, 
or even somewhat infundibuliform, dirty white, rugose. 
Stem about 2 of an inch high, 3 of a line thick, not rooting, 
but attached denii as in Ag. stipitarius; clothed with very 
short cinereous velvety down, slightly incrassated above, 
where it is at length smooth and rufous. 
Gills pallid, acutely decurrent, with their interstices, for 
the most part, even. 
Allied to Ag. (Marasmius) fetidus. The specimens are 
few, and not in so good condition as might be wished, but 
the characters are so marked, that there will be little diffculty 
in distinguishing this species.

Bot., vol. 2. p. 497.

pulverulento brunneolo; lamellis 3-6 ventricosis luteo-pal- 
lidis, interstitiis levibus.
