Phanerochaete australis Jülich View in CoL

Basidiome resupinate, membranaceous, white to isabelline when young, or cream to pale brown when old, hymenial surface smooth or slightly tuberculate, margin abrupt. Hyphal system monomitic, all hyphae with simple-septa, subicular hyphae thick-walled, 4–7 µm in diam., not encrusted, subhymenial hyphae thinwalled, 2–3.5 µm in diam. Cystidia more or less fusiform, with a tapered or obtuse apex, not acute, 40–55 × 9–12 µm, distinctly thick-walled, walls thickened up to 3 µm, hyaline, usually smooth or encrusted only in the apical part. Basidia clavate, 20–25 × 3–4 µm, with four sterigmata, simple-septate at the base. Basidiospores narrowly ellipsoid, 4–5.5 × 2–2.5 µm, smooth, thin-walled, IKI- ( Fig. 13 View FIGURE 13–16 ).

The species is easily distinguished by the thick-walled cystidia with a variable encrusted apical part, small basidiospores, and simple-septate hyphae.
