Entoloma duplocoloratum

The fruitbody is a mushroom, with a cap atop a central stem. The cap is 10-30 millimetres in diameter, initially conical to hemispherical, but later flat or somewhat undulating. It is mostly medium-brown but with a much darker brown central area and is markedly striate in the outer half. The cap has radial fibrils that may aggregate to create minute scales. The gills are greyish pink with irregular edges that may be coloured brown. The stem may reach 40 millimetres in length and is 1-4 millimetres in diameter. It is smooth, dry and bluish-grey with a short, fluffy white coating near the base.    

Spore print: brownish-pink.

There is neither a partial nor a universal veil. 

The first published description of this species was published in 2008, based on material collected in New Zealand, and it is found also in Tasmania. It occurs in various forest types.

Look-alikes

This is probably a fairly distinctive species. Entoloma purpureofuscum has the closest resemblance but the cap is dark purplish brown centrally and the gill edge, if different from the face, is pale purple brown. The stem is pale blue-grey fading to grey or brown-purple. The cap of Entoloma melanophthalmum has a distinct lilac-violet hue at the margin (sometimes also over the whole cap) and the gill face and edge are concolorous. My information about those two species comes from the reference listed below. A look through that book shows a few other blue-stemmed/brown-capped species. However, careful attention to all the features of Entoloma duplocoloratum noted above should remove any chance of confusion.
