186 DECADES OF FUNGI. 
On the ground. Swan River. Mr. Drummond. 
Pileus forming a cup 6 inches deep, 16 inches broad from 
margin to margin following the concavity of the cup, fleshy 
except at the lobed incised margin which is very thin and 
acute, perfectly smooth, reddish brown. Stem central irregu- 
lar, 13 inch high and thick, collecting by its mycelium a mass 
of small pebbles, compressed smooth of the same colour as the 
pileus. Gills very broad in the centre, distant, thick at the 
base, thin and acute at the edge, now and then branched, 
running down to the base of the stem, ochraceous with the 
edge umber when dry; interstices either perfectly even or 
remarkably reticulate in the same individual. 
Allied to Ag. ostreatus, but a far more magnificent species ; 
when fresh it must be one of the finest of the genus. —

2. Bolbitius mitreformis; Harv., pileo membranaceo 
mitreformi acuminato, supra medium striato; stipite gracili 
flexuoso candido minutissime albo-farinaceo, ismen adscen- 
dentibus valde attenuatis angustissimis anastomosantibus, 
subinde furcatis. (Tam. VI. B.) 
On tenacious clay containing a little iron. Devil's Mount, 
C.B.S. W. H. Harvey, Esq., 1841. 
Gregarious. Pileus 1 inch high, 3 of an inch broad, mem- 
branaceous, mitreform, much acuminated, becoming more 
so as the plant advances in age, finely striated more than 
half way up, margin very thin, ragged. Stem fistulose, nearly 
21 inches high, 1 line thick, white, often twisted, flexuous, 
BARET with very fine white meal. Gills, extremely nar- 
row, ascending, much acuminated, anastomosing, sometimes 
forked, argillaceous. Spores broadly cymbiform with a 
minute, lateral peduncle, 
Resembling in form Ag. callosus, but evidently allied to - E 
Ag. titubans, Boltonii, &c., now separated under the name
