Curator Response

Hi Rick,

We direct all our fungal queries to Bob Cummings, who teaches in the Botany Department at Santa Barbara City College in the Biological Sciences. Here's his response:

"This looks like an oyster mushroom, Pleurotus ostreatus. It's a saprophyte on hardwoods, common on our dead and downed live oak logs. Grows shelf-like, with reduced, eccentric stipe, gills and spores are white. It is listed in field guides as a good edible, but in my experience it needs to be well cooked, and even then might cause mild gastrointestinal symptoms."
