to light brown, tlie lower white. Stipe inesopodial, r. to 21in. (2 to 6 cm.) long, 
5 to 1.5 mm. thick. Pores small, roundisli or irregular, 2 to .3 mm. long. Spores 
abundant, cylindrical, smootli, hyaline, (i x 2 ft.’’ — Lloyil. New South Wales.

31(i. Polyporus tumulosus Cooke (L., tumulosus, bearing a hillock or lump). — 
In sandy Kucalyptus forest laml which has been recently burnt, a Polyporus has 
been found in New South Wales, South Australia, and Tasmania after late 
summer or autumnal lains, even wlien mere sprinkling, which we attidbute to this 
species originally descrilKMl from Queensland. We have only found specimens in 
country which I'las been recently l>urnt but on such areas the fruiting bodies 
rapidly emerge after the rain, ap])earing witliin a fortnight of the burn and 
consequently less since the rain. The pileus emei'ges from a false sclerotium of 
myclium-impregnated sand, roughly delimited by' a. thin indefinite fragile blackish 
crust. It would seem as if, in the absence of fire, tlie mycelium over perhaps 
manv years merely' vegetates in the humus, laying up food-stores which are 
conc'enti-ate{l in the false sclerotium. For the latter to translate these into 
fruiting bodies (tlie stem and pileus bearing the spores), fire would appear to 
tie necessary', eitlier on account of tlie heat or more likelv' as the result of the 
potasli and other salts and chemical sulistances set free bv the blaze and carried 
down by the rain. The stem often only emerges above the ground for lin. to 
lin. (1.2 to 2.5 cm.), a longer portion (2in., 5 cm.) being buried and sand- 
incrusted. Tliis is carried on for perhaps another 2in. (5 cm.) as mvcelium- 
impiegnated sand to end in the false sclerotium an inch (2.5 cm.) or considerably 
more in diameter. From the shortness of the stem above ground, the pilei are 
but little above tlie ground-level and are often dirt-bespattered. March and 
■Vliril. 
Houtli Australian specimens, collected on March .31 and April 1, 1929, in 
country burnt on Alarcli 12, followed a few days later by slight rain, near 
lllackwood (iiillv, Kuit ])0 district, are described as follows: — Pileus 2 to .3in. 
(5 to 7.5 cm.), convex, rather irregular, edge sometimes with irregular bays, 
smooth, not apparently' viscid when moist, with a cuticle which tends to crack, 
near Saccardo ’s rmiier (xxix.). Tubes 2 to 3 mm. long, slightly decurrent, 
dingv creamv white, sometimes becoming stained brownish when old, orifices 
rather irregular, aliout 11 in 1 mm., di.ssepiments thin, somewliat compressed, 
wanting in j)laces. iStem central, i to 2in. (1.2 to 5 cm.) abo\'e ground, about 
lin. (2.5 cm.) buried and sand-incrustod, moderately stout to stout (1 to lin., 1.2 
to 2.5 cm.) , a little fibidllose, white, later sometimes with brownish stains, passing 
below into a core of mycelium and sand, leading to a false sclerotium, lin. 
(2.5 cm.) or more in size, composed of sand and mycelium suirounded bv a thin 
dai'ker crust. Spores elongate<l, obli(iue, mummy'-shaped, white, 10 to 15 x 5 to 
() y, usually' 13 x 5.5 y. Specimens were also collected in l)uvnt stringy-bark 
(A', obliqiia L’llerit.) country at Alount Lofty' on Ma.rch 27, 1929. 
3,17. Polyporus Schweinitzii Pr. (After Ludwig David von Schweinitz, an 
American my'cologist) . — Wuiablc, often deformed, at the base of stumps, usually 
with an excentric or nearly lateral stem or stem-like attachment, rarelv with 
the stem nearly' central. Pileus up to 3 to (iin. (7.5 to 15 cm.), nearly plane 
or dej)ressed in the centre, irregulai’, sometimes with deformed secondary' pilei, 
rarely as a rosette, surface \'illous, irregularly I'ugose or coarsely' tubercular or 
lacerated, edge a little irregular or even lobed, often with incor))orate<l leaves or 
grass-stems, becoming smooth when old, Tawny' to Ochraceous Tawny- (xv. ) or 
sometimes near Raw Sienna (iil.), the edge sometimes Cream Buff (xxx.) or 
pallid, when young Yellow Oclue (AV.) to Chamois (xxx.) and pale yellow, w'hen 
old very' dark brown, llymenial surface concavo-convex, decurrent, often dee))ly 
so, on tlie stem, nearly- vertical in young plants when their shape is that of an 
inverteil cone, at first pallhl whitish, jiassing througli Warm Buff (xv.) to dark 
brown (Dresden Brown, xv.) with a yellowisli or greenish-vellow glint; pore 
orifices minute, 3 to 5 in 1 mm., varying a little in size, often partly- sealed, 
dissepiments thin; tubes 2 to 4 mm. deep. Tawny- Olive (xxix.) to glaucous 
brown. Context up to over lin. (2.5 cm.) thick in the centre, tapering outwards, 
ratlier radiating, light in weight, tough, punky-firm, Ochraceous Tawny- (xv.) to 
Cinnamon Brown near the base. 8tem lin. (2.5 cm.) or less to 2in. (5 cm.), 
stout (lin., 2.5 cm.) to rather slender, very irregular, often knobby and distorted, 
attenuated downwards, villous, near Yellow Ochre to Ochraceous Tawnv and 
Cinnamon Brown (xv.). Spores sulispherical to elliptical, white, 8 x 5 to <i.5 y, 
8 y (in New- South Wales specimens the spores are mostly smaller, 5.2 x 3.5 y.
