This came up soon after a processing a burn pile. I use an unusual process for completing the burn in which I disperse the hot charcoal before the pile would otherwise cook the soil. The surface was black char and still had visible undecomposed organic matter in it.

Interestingly, I found this before the fruiting bodies became evident as I was planting native grass plugs at the time. I dug into the crusted burned surface and found a very dry, brittle, and bright orange substrate which I suspected to be fungal. So when I was processing another pile about a week later, it was no surprise to see patches of this obviously fungal surface. I photographed it, sent it to an expert for identification, and he indicated that this was the first observation of this species in Santa Cruz County. There is very little burning here and most of it cooks the soil.

This location was on a sandy ridge that was an overgrown forest that grew out of a chaparral. Nearby plant species are Qurecus shrevii, Q. agrifolia, Arbutus menziesii, Hetermomeles arbitufolia, Toxicodendron diversiloba, Ceanothus papillosus and cuneatis, Arctostaphylos tomentosa, Calamagrostis rubescens, Elymus glaucus, Sanicula crassicaulis, Dichelostema capitatum, and various native forbs.
