Volvariella bombycina, commonly known as the silky sheath, silky rosegill, silver-silk straw mushroom, or tree mushroom, is a species of edible mushroom in the family Pluteaceae. It is an uncommon but widespread species, having been reported from Asia, Australia, the Caribbean, Europe, and North America. The fruit body (mushroom) begins developing in a thin, egg-like sac. This ruptures and the stem expands quickly, leaving the sac at the base of the stem as a volva. The cap, which can attain a diameter of up to 20 cm (8 in), is white to slightly yellowish and covered with silky hairs. On the underside of the cap are closely spaced gills, free from attachment to the stem, and initially white before turning pink as the spores mature. The mushroom grows singly or in clusters, often appearing in old knotholes and wounds in elms and maples. V. bombycina contains compounds with antibacterial properties.
The species was first described in 1774 by German naturalist Jacob Christian Schäffer as Agaricus bombycinus. Throughout its taxonomical history, it has been shuffled to several genera, including Pluteus (by Elias Fries in 1836), Volvaria (Paul Kummer, 1871), and Volvariopsis (William Alphonso Murrill, 1911).Rolf Singer placed it in its current genus, Volvariella, in 1951. Other names that have been applied to the species include Jean-Baptiste Lamarck's Amanita calyptrata and August Johann Georg Karl Batsch's Agaricus denudatus (both published in 1783), but these are illegitimate names as Schäffer's earlier 1774 name has priority.
