In the foregoing table the names of the genera are printed in small 
capitals, and those of the subgenera in italics. 
From the Agaricini we pass to the Polyporei, in which, whilst 
the hymenium is still inferior, it is no longer spread over a 
folded membrane, hut lines the interior of pores, which are 
parallel to each other, and at right angles to the plane of the 
pileus. There are but few genera, and these sufficiently distinct 
to require no elaborate description. The only genera in which 
the whole substance is fleshy are Boletus and its immediate 
allies, Strobilomyces and Fistulina , at least in so far as the 
Australian Flora is concerned. Between Boletus and Strobilo- 
tuyeos there is very little difference, save that in the latter the 
Pileus is broken up into large scales, whereas in the former the 
pileus is even. Fistulina differs from both those in the pores 
being the perforations of distinct separable tubes, and not 
closely adnate and confluent tubes, as in Boletus, Strobilomyces, 
and Polyporus. The residue of the genera, the substance, even 
when it is rather soft and fleshy at the first, soon becomes firm 
ft nd hard, often leathery or woody. The old genus long known 
^Polyporus has been broken up into four genera, in all of which 
the hymenium is similar, the difference being that in Polyporus, 
as now limited, the pileus is at first fleshy, but tough, becoming 
hardened, rarely fragile, without furrows or zones on the pileus, 
and with only a single stratum of pores. In Fames the pileus 
18 Woody, with a hard crust, concentrically sulcate, and, being 
perennial, usually with more than one stratum of pores, each 
stratum being the growth of a single year. In Polystictus the 
pileus is more or less leathery, with a zoned, usually somewhat 
hairy or velvety surface, a fibrilloso internal stratum, and only 
°ne series of pores. In the fourth genus, or Poria, there is no 
Ihue pileus, the whole fungus being spread upon, and adnate to 
the matrix, so that it appears as a stratum of pores seated upon 
a kind of subiculum. Trametes differs from Polyporus and its
