Tricholoma eucalypticum

The fruit body is a mushroom with a cap atop a central stem. The cap may be up to 14 centimetres in diameter and is convex to flattened, pinkish brown or buff, smooth (but sometimes cracking to create tiny scales, more so centrally), at least somewhat viscid when fresh or moist and shiny when dry. The gills are white to creamy but with age may develop some brownish spotting. The stem (up to 10 centimetres long and 4 wide) has a colour similar to the cap, though paler, and with a mealy to finely scaly surface

The mushrooms may appear in dense clusters, with mutual pressure deforming the caps. Sometimes the stems are quite short, with caps barely above the ground or even partly buried.   

There is neither a partial nor universal veil, though some descriptions note that a ring of fibrils, suggestive of a cortina remnant, may sometimes be present.

This species is found on the ground near eucalypts in a variety of sclerophyll forests or woodlands.

The original description of this species (by A. Pearson on pages 293-294 of Transactions of the British Mycological Society, vol. 33, 1950) was based on specimens that had been collected in South Africa in 1948 (“in sandy ground under or near gum trees (Eucalyptus sp.)”, to quote from Pearson’s habitat description). Pearson said that J. B. Cleland (Toadstools and Mushrooms of South Australia, Part 1, 1934) had seen this species but had incorrectly identified his specimens as Tricholoma coarctatum, owing to some confusion in the source of information that Cleland had relied on.
