Amanita subpallidorosea is a mushroom of the large genus Amanita, which occurs under oaks in southern China and Taiwan.
Similar species
Amanita subpallidorosea is a medium-sized mushroom, and predominantly white. The cap is initially conical, before becoming more convex and flattening, sometimes with a central boss. Measuring 3 to 6.5 centimetres (1+1⁄4 to 2+1⁄2 inches) in diameter, the cap is white initially, before developing a pale pink, more prominently in the centre and paler at the margins. It can be slightly sticky when wet. The flesh is white. The crowded gills are free and around 4 millimetres (1⁄8 in) deep. The stipe is 7 to 12 cm (2+3⁄4 to 4+3⁄4 in) high and 0.6 to 1.4 cm (1⁄4 to 1⁄2 in) thick, is white, cream or pale buff in colour and bears a thin white membranous ring. The bulb at the base is 1.5 to 3 cm (1⁄2 to 1+1⁄4 in) across. The spore print is white, and the round amyloid spores are 8–12 x 8–12 μm viewed under a microscope. Their surface is smooth. The mushroom turns yellow when potassium hydroxide is applied to it.[1]
It can be distinguished from Amanita pallidorosea as the latter's cap has a pronounced boss and its spores are smaller when viewed under a microscope. Other lethal amanitas in China are generally white.[1]
It is closely related to the destroying angel mushrooms A. virosa and A. ocreata.[2]
Distribution and habitat
A. subpallidorosea is found under oaks of the genera Quercus and Cyclobalanopsis in Guizhou province as well as Taiwan.[1]
