Remarks (internal):The species is usually recognized in the field due to its distinct black cuticle and the dark brown pileus, tubes and context. Macroscopically reminiscent of Fomes , but this species has a moresrusty brown context with a granualr mottled core at the base of the basidiocarp.
The closely related species G. applanatum of the temperate zone has similar basidiocarps, but a thinner cuticle, context without black bands and shorter spores.

Description:Ganoderma australe (Fr.) Pat. ,
Bull. Soc. Mycol. Fr. 5:67, 1889. - Polyporus australis Fr., Elench. Fung. 1:108, 1828. - Ganoderma tornatum Pers.
Basidiocarps perennial, applanate, ungulate, often irregular when growing from cracks etc., normally dimidiate and semicircular in outline, variable in size, 4-40 cm long, 4-20 cm wide and up to 10 cm thick in single basidiocarps, woody hard when dry, pileus dull, cocoa-brown to deep umber to black in old specimens, dying or weathered specimens more greyish, surface often covered with a cinnamon to pale cocoa powder of deposited spores, otherwise surface glabrous, smooth, mostly distinctly sulcate in variable zones, somewhat cracking with age and drying, black cuticle present, 0.2-3 mm thick, increasing in thickness towards the base, margin light- coloured in actively growing specimens, whitish to yellowish, pore surface white to cream in actively growing specimens, then dark when bruised, in older and resting species, pale to umber-brown, pores round, entire, quite thick-walled, 3-5 per mm, tubes dark brown in section with light-coloured tube-walls, in older parts often stuffed with white mycelium, weakly stratified, up 6 cm thick, context evenly dark bay brown, rarely with some white spots, in most specimens with one or several horizontal black resinous or melanoid bands above the tubes, but these bands are apparently absent in some specimens.
Hyphal system dimitic, generative hyphae with clamps, thin-wal­led and hyaline, 1.5-3 ?m wide, skeletal hyphae dominat­ing in the basidiocarp, variable brown to yellow, thick-walled to solid, up to 6 ?m wide, branching variable, in lower part unbranched and then arboriform in the top, often irregular, binding hyphae delicate, mostly very thin, 1-2 ?m wide and richly branched, easiest to find in the white mycelium filling the old tubes.
Basidia barrel shaped, 15-20 x 6-10 ?m and with 4 large sterigmata.
Basidiospores truncate, golden-brown, echinulate, 7-12 x 5-8 ?m.
Substrate. On deciduous wood.
Distribution. Pantropical and common in tropical America and because of the long-lived and large basidiocarps it is conspicuous and thus frequently collected.
