Pleurotus, Redwood East Bay Regional Park, Oakland, California
Oyster mushroom (I think) on California laurel (Umbellularia californica). I am not a fungi expert so please me know if you disagree.
Tentatively identifying as Oyster Caps. Would appreciate confirmation. The colony is about 12" across, so each cap is a bit less than half that. Caps are very firm, but not woody. The whole group can be wiggled easily. They give a little, especially at the edges, and I have the impression I could break them with my hands. Gills below. Apparently growing directly on the ground in the woods, but there could easily be a decaying stump down there.
Seen growing on a dead Douglas fir along the lower dirt trail. The largest specimen was approximately twenty cm across. The fruiting body was not so stiff as, for example, Trametes.
Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world.Pleurotus fungi have been used in mycoremediation of pollutants such as petroleum and polycyclic aromatic hydrocarbons.
