California Black Trumpet

The edible but less common Craterellus atrocinereus has a very similar appearance. It differs most obviously in that the outside/underside of the fruiting body is strongly veined rather than smooth. It also differs in that it is not tubular when young and it grows in association with coast live oak in the spring. The edible Craterellus tubaeformis is superficially similar to the rare yellow variety of this species. It differs most obviously in that it has a discrete stem section and the underside of the cap bears false gills.
