The fruit body is a mushroom in which, at maturity the cap is funnel-shaped, often with a somewhat wavy margin and the margin is slightly inrolled. The cap is some shade of yellow brown and may reach a diameter of around 10 centimetres.
The stem may be central or off centre and has a colour similar to that of the cap. It may be up to 5 cm long and 2 cm in diameter.
The gill colour is similar to that of the cap, or a little paler, and the gills are forked.
There is neither a partial nor universal veil.
Spore print: brown.
The mushrooms are found on the ground near native trees. Another 'paxilloid' species that is common near northern hemisphere trees in suburban Canberra is the introduced Paxillus involutus.
The species Austropaxillus infundibuliformis was first described in 1927 (as Paxillus infundibuliformis) based on specimens collected in SA and Victoria. Austropaxillus muelleri is a visually similar species but differs in microscopic features (and some have argued that the two species identical).
Austropaxillus infundibuliformis group is listed in the following regions:
