Common Names: Veiled oyster
Sub-category: Oyster Mushrooms
The cap, growing to about 13 cm, is pale, beige or (in variety tephrotrichus) greyish; later it can turn yellowish. Veil remnants may adhere to the edge. At first it is velvety (tomentose) and the tomentum can develop into grey-brown scales; in old specimens the surface becomes bare and may crack. The whitish or pale brownish lateral stem may be very short or up to about 8 cm long, generally with a membranous ring. The gills are decurrent well down the stipe and may anastomose (criss-cross) at the lower extreme. They are white or cream.
This mushroom is saprobic on dead wood and can also be a weak parasite of trees. It occurs especially on oak (from which it derives its name), but also on beech, other broad-leaved trees, and occasionally on conifers. It is often solitary or may grow in small groups. Appearing from summer to autumn.
