Inocybe mixtilis

The fruitbody is a mushroom, with a cap atop a central stem. The cap is up to 3 centimetres wide, brownish orange to medium brown, with radially orientated fibrils flat against the surface (giving the cap a radially striate appearance) . Initially the cap is more or less conical and with age opens out but always keeps a noticeable central hump (or umbo). The gills are initially whiteish but as the spores mature they turn greyish brown. The stem is white (to slightly brownish with age), may grow to a few centimetres long and half a centimetre wide and has a bulbous base with a slight circular ridge around the top.  

Spore print: greyish brown.

There are no clear veils, though wispy traces may appear in very young specimens.   

This species is widespread in the northern hemisphere and in Australia is found in association with introduced tree species.

Look-alikes

This is likely to be a fairly distinctive species when found growing alongside introduced tree species. However, since the colours are fairly common, if native trees or shrubs are nearby or you are in a treeless area, be wary of assuming you are seeing this species.
