Ganoderma australe (Fr.) Pat.
Index Fungorum number: 100745; Faceoffungi number:xxx
Ganoderma australe is a large bracket fungus that grows up to typically 25 cm across but exceptionally 50 cm, and 5 to 25 cm thick, with a pale margin and lower surface, and a dark brown or dark grey upper surface. The tube layer is brilliant white when ready to release spores, but as with other Ganoderma fungi the spores are brown and soon colour the surrounding area, including parts of the top of the bracket, with a dense brown dust. The red-brown tubes of the G. australe are tiered, a new layer being produced each year. The small round pores, typically 3 or 4 per mm, are white when the fruiting body is growing and approaching the time when spores will be released, turning brown with age or when bruised. A new tube layer grows on the lower surface each year. (Fig. 1)
