Tricholoma aurantium, commonly known as the golden orange tricholoma, is a species of agaric fungus in the genus Tricholoma.
Originally described by Jacob Christian Schäffer in 1774,[2] it was transferred to the genus Tricholoma by Adalbert Ricken in 1915.[3]
Description
The cap is broadly convex to more or less flat, measuring 3–10 cm (1.2–3.9 in) wide with a margin that is initially rolled inward. Fresh specimens are sticky or slimy. The cap color is orange to dull reddish-orange.[4] Parts that have been handled bruise dark red.[citation needed] The initially smooth surface can break into a matrix of fibrils and scales.[4] The closely spaced gills are whitish, but develop brownish to reddish-brown stains in maturity. They are adnate to adnexed, sometimes notched.[4] The often hollow stipe measures 4–8 cm (1.6–3.1 in) long by 1–2 cm (0.4–0.8 in) thick, and is either roughly the same width throughout,[4] or tapers slightly to the base. Its surface is covered with dense orangish scales that terminate in a line near the top of the stipe, where it is white. The white, mealy tasting flesh does not change color with injury.[5] The odour is unpleasantly farinaceous.[4]
The spore print is white.[4] The spores are smooth, ellipsoid, and inamyloid, measuring 5–6 by 3–4 μm.[5] The mushroom is inedible[6] due to its extreme unpalatibility.[4]
Habitat and distribution
The fruit bodies grow scattered or in groups or clusters on the ground with various species of conifers, with which it has a mycorrhizal relationship.[4]
It is widely distributed in North America.[5] It is found in Asia (India,[7] Pakistan).[8] The ectomycorrhizae of T. aurantium has been reported with Pinus wallichiana and Abies pindrow in Pakistan,[8] and with Abies alba (silver fir) in Italy.[9]
