Hohenbuehelia mastrucata
Lilloa 22: 255. 1951.
Common Name: none
For description see Siegel et al. & Siegel & Schwarz.
Solitary to scattered to gregarious on decaying wood; rare in California, known from Tanoak (Notholithocarpus densiflorus), Black Oak (Quercus kelloggii), and willow (Salix sp.); fall and winter.
Unknown, far to rare to be considered for the table.
Hohenbuehelia mastrucata can be distinguished by its pleurotoid shape, brownish-grey to greyish cap covered with a tomentum of white to cream colored scales, white spores, and a distinct gelatinous layer under the cap cuticle. Hohenbuehelia grisea is smaller, with a dark grey patchy-tomentose cap.
