Field Notes - A large clustered mass (100-150) of bracket-like fungi fruit bodies, spotted next to Lorna Pass in Lane Cove National Park after days of rain. They were growing on a decaying small branch on the ground on top of leaf litter. Each fruit body was up to 1cm x 1cm in size, and a very flat rounded kidney shape. They had a creamy white cap, darker towards the stipe. The stipe was attached to the underside, which had creamy white pores. I think this fungus is the Little Ping Pong Bats - Dictyopanus pusillus.

This is the common 'Fomitiporia robusta' on tea-tree. I finally managed to get a sequence. As we might expect (based on micromorphology at least) it is quite unrelated to Fomitiporia robusta associated with northern hemisphere oaks. This is closely related to F. eucalypti - which makes sense. It probably needs a new name, although there are some older names of species described on Australian myrtaceous hosts that haven't been investigated recently.

Growing on the underside and sides of a rotting log in a native bush remnant. Mostly resupinate, but forming narrow, firm-leathery, shelves up to 14 cm wide on the side of the log which project out up to 35 mm and are up to 20 mm thick. Upper surface dark brown but with a wide, pinkish-white margin. Lower surface pinkish-fawn, covered with small pores (7-9 per mm) except for a narrow sterile margin. Fruit bodies readily sliced with a knife, context yellowish-brown overlying a chocolate-brown pore layer up to 6mm thick. Fresh fruit body with strong mushroomy odour.

Soft white bracket on fallen beech, to 15 cm diam, fragile. Single layer of tubes. 6 pores per mm, sweetish smell, no taste. Tube layer to 1cm thick. Tissue dimitic, clamped. Spores hyaline, not dextrinoid 3um.
This is Tyromyces guttulatus sensu Cunningham, which is not the same as the northern hemisphere original (-Calcipostia guttulata). This is undescribed and perhaps related to Aurantiporus pulcherrimus. The genus Aurantiporus is probably not appropriate. The type species has not yet been sequenced. An appropriate genus is probably Pappia, based on P. (Tyromyces) fissilis, which is also related.

Substrate Beilschmeidia tarairi. Forest type: mature taraire dominant hardwood forest. White above, below and within, bruising brownish. Spines up to 7mm toward the centre on the underside. Easily torn. Seemed to have a stipe (photos 1, 7 and 9). Photo 8 shows pileus surface.

Mucked up a little, thought I took a photo in situ but took a photo of a totally different species..
On fallen, well decayed pine. Leathery flesh, woody stipe. Smell very much like fresh A. bisporus. Taste vaguely mealy/woody.

Sapromamanita galerumgandalfi (ined.), aka Noddy Flycap (Amanita 2 Ridley). Photos taken by Wael Abbas and posted here as a record with his permission. Unfortunately, the Sydney herbarium said it was unimportant so it was not kept for scientific study.

Growing on a fallen beech log in beech-dominant native forest. Up to 10 cm across, dark brown woody brackets with numerous layers stacked vertically. Pore surface white which marks slightly when scratched (see third photo) but does not leave a dark brown mark as with Ganoderma. The fourth photo shows a larger and much older specimen of presumably the same thing on a nearby stump, covered in brown spores.
