OF 
AUSTRALIAN FUNGI. 
Family I. HYMEBTOMYCETES. 
Mycelium floccose, giving rise at once to a distinct hymenium, 
or producing a variously shaped, naked, or volvate reoeptacle, even, 
or bearing on its upper or under surface various folds, plates, 
prickles, &c., clothed with fertile hymenial cells. Spores naked, 
mostly quaternate, on distinct spicules. Berk. Introd. p. 351. 
Hymenium, normally inferior — 
Fruit-bearing surface lamellose .... Agaricini. 
Fruit-bearing surface porous or tubular . Polyporei. 
Fruit-bearing surface clothed with prickles. Hydnei. 
Fruit-bearing surface even Thelephorei. 
Hymenium, superior or encircling — 
Clavate or branched, rarely lobed . . . Clavariei. 
Lobed, convolute, or disc-like, gelatinous . Tremellini. 
Order 1. AGARICINI. 
Hymenium inferior, spread over easily-divisible gills or plates,, 
radiating from a centre or stem, which may be either simple or 
branched. — Fr. Epicr. p. 2. 
Genus 1. AGARICUS. Linn. Syst. Nat. (1725). 
Spores of various colours ; gills membranaceous, persistent, 
'vith an acute edge : trama tloccose, continent with the inferior 
bymenium. Fleshy fungi, putrifying, and not reviving when once 
dried, hence differing from such genera as are deliquescent, coria- 
ceous, or woody. 
This genns is divided into five series, according to the colour of the 
spores — 1, Leucospori ; 2, Hyporhodii ; 3, Deraiini ; 4, Pratelli; 5, C jpri- 
narii.
