Marasmius equicrinis has a specialized pellicle on the pileus, 
the cells being simple, up to 20 jjl broad, echinulate at the 
upper end. 
Agaricus ramentaceus Berk, is apparently a nomen nudum. 
Lé veillé, in Zollinger, “ Systematisches Verzeichnis der im 
Indischen Archipel gesammelten sowie der aus Japan 1842/48 
empfangen Pflanzen,” p. 16, lists “ A. ramentaceus Berk., H. 
1144. Ad ramos et folia pr. Tjikoya/’ without any descrip- 
tion. This is the reference cited by Patouillard. Zollinger’s 
list was published 1854-55, but the same list of fungi was pub- 
lished previously in Moritzi, Systematisches Verzeichniss,” 
&c., 1845-46 ; in the latter the record is ''Agaricus ramenta- 
ceus Berk., No. 1144.” In Hooker’s London Journal of 
Botany, III. (1844), p. 329, Berkeley described specimens of 
Zollinger’s collection which had been sent him by Montagne, 
but he did not describe A. ramentaceus, nor is there any 
description under another name which would apply to Patouil- 
lard’s species. Berkeley’s earlier lists appear to be equally 
blank, and hence it would seem that the description was 
never published. The first effective publication of Agaricus 
ramentaceus in this sense is therefore Patouillard’s in 1897. 
There is a previous Agaricus ramentaceus Bull., which is an 
Armillaria. 
In ‘‘ Fragmenta Brasilica ” (Ann. MycoL, Vol. VI., 1908, 
page 531) F. Theissen re-describes Marasmius trichorrhizus 
Speg. He states that it is identical with M. equicrinis Mull., 
M. Balansae Pat., M. polycladus Mont., and M. repens P. 
Henn., while M. Baumanni P. Henn. is only a variety. The 
pileus is 0*5-5 mm., in diameter, light to dark brown, flat 
or depressed in the centre, wdth or without a papiUa ; the 
gills are at first white, very narrow, but generally become 
brown and broad, even ventricose ; the spores are somewhat 
pear-shaped, 8-13 X 4*5-6 (x. He notes that the fructi- 
fication arises either from the rhizomorphoid mycelium or 
independently from twigs. 
Rick (Ann. Myc., IX., page 176) also states that M. trichor- 
rhizus Speg. = M. polycladus Mont.; that M. Balansæ Pat. is a 
form with a larger pileus ; and that M. equicrinis Mull, and 
M. repens P. Henn. are not ‘‘ spezifisch verschieden.”
