444 Rev. M. .T. Berkeley on some Fungi collected 



liar obligation to my friend Dr. Montagne, who has not only 

 supplied me with specimens of the greater part of his pub- 

 lished species, but has communicated many novelties of the 

 greatest interest before publication. 



1. Agaricus salebrosus, n. s. Sordide flavus, pallidus ; pileo 

 subreniformi lobato subplicato subcarnoso, sulcis brevibus ra- 

 diantibus notato, pellucido-striato ; lamellis latis subdistanti- 

 bus, acie subdentata ; stipite nullo. Darw. No. 216. 



On sticks, covered with bark. Rio Janeiro. May 1832. 



One to two inches or more broad, of a pale dirty yellow. Pilei at 

 first entirely resupinate, reniform, sometimes somewhat confluent ; 

 at length reflexed and free, more or less orbicular, smooth, more or 

 less lobed and almost plicate, marked with short distinct radiating 

 shallow furrows ; margin thin, acute, pellucido-striate. Gills broad, 

 rather distant, their edge slightly toothed. Stem none, but the por- 

 tion of the pileus by which it is attached is thickened. 



Allied to the species of the first section of Fries' division 

 Resupinati in the tribe Pleurotus, in which it will range next 

 to Ag. porrigens. The upper stratum of the pileus does not 

 appear to be gelatinous.

Tahiti. November. 



Pileus 3 inches broad, 2 \ inches long, reniform, thin but coriaceous 

 and rigid, subimbricated, very concave above, marked with many con- 

 centric grooves, most of which are shallow, and a few obscure radia- 

 ting ribs scarcely visible except towards the margin, where they form 

 small vaulted knobs, with corresponding depressions in the hymenium, 

 smooth, very minutely rugose, of a tawny wood colour, with nume- 

 rous darker zones. Hymenium and substance wood-coloured. Pores
