erecto, gracili, subrufo, glabro; basi disciformi strigoso-to- 
mentoso. (Tas. XIV 
On bark, New Ireland; July. On cocoa leaves, Mar- 
quesas; Jan. 1840. 
Pileus § of an inch broad in the largest specimen, convex, 
membranaceous, very delicate, forming at first a convex wart 
upon the bark, without any appearance of a stem, clothed 
with short scattered curved rather obtuse prickles, which at 
length entirely vanish; margin slightly striate. When dry, 
the sides are much contracted, so as to give the pileus the 
appearance of being strongly umbonate. Gills ascending, 
slightly ventricose, free, brown like the pileus, but paler. 
Stem $ an inch high, scarce 3 a line thick, even, obscurely 
fibrillose, attached by an orbicular dise which is clothed with 
recurved strigose down.—Allied to Ag. stylobates. 
Tas. XIV. a. Ag. echinulatus, nat. size.; b. two indi- 
viduals, magnified; c. section, magnified; d. prickles from the 
ES plant ; magnified. 
3. Ag. (Marasmius) zerophyllon, n. s. ; pileo campanulato, 
RE reticulato-rugoso, umbilicato, flavo- 
fusco; lamellis paucis, interstitiis reticulatis; stipite equali 
compresso subtilissime velutino. (Tas. XIV 
n wood, New Guinea, Aug. 
Pileus 2 of an inch broad, coriaceous, membranaceous, of 
a beautiful yellow brown, at first convex, at length broadly 
campanulate, with a rugose umbilicus; borders deeply reti- 
culato-rugose, with a velvety lustre, waved but not lobed. 
Stem $ of an inch high, } a line thick, equal, of the same 
color as the pileus, very obscurely velvety, at length nearly 
smooth. Gills grey, about 10 in number, slightly adnate, 
with shorter ones either free or branching from the longer ; 
their interstices strongly reticulated. 
This is a very well marked species, but allied to none with 
which I am acquainted. It has the form of Ag. fetidus, 
Sow. 'The specific name is intended to express the peculiar 
appearance of the pileus, like that of some dry leaf.
