Found in an Eucalyptus globulus dominant urban forest on the edge of a golf course in the Presidio, Golden Gate National Recreation Area
Growing on mixed substrates (woody material and dead grasses) under Eucalyptus globulus
Pileus bight red/orange, appearing slightly velutinous. Lamellae white, subdistant to distant, broadly to narrowly attached. Stipe elongate, white and opaque at apex, becoming tomentose and brown at base

On hardwood. Several caps were seen. 4-5 pores per mm, with an irpicoid aspect. Pore length a bit less than 2mm. Pores look grey but up close they really look gelatinous and glassy. Strong fungal smell, a bit sweet. Fruitbody is spongy and flexible. Specimen examined was 2.5 cm wide. Shady woods. C. populus or C. caesiosimulans.

Growing on dead Quercus agrifolia leaves in an area with low severity burn, Quercus agrifolia, Arbutus menziesii and Sequoia sempervirens dominant
Sporocarops about the size of mustard seed, covered in white strongly filaments. Some sporocarps have pseudo-lamellae which express themselves as distant, smooth ridges (see in photo 1-3)

Growing along roadcut in redwood forest. Pileus brown, minutely granular-scaly. Lamellae thick, widely spaced; yellow to white, widely attached to decurrent. Stipe bright yellow, brittle, dry, ornamented with white granular chevrons at the apex and bright white farina at base.

Odor is like a mixture of rubber and cleaner, an odor reminiscent of a garage; I smelled it again hours later and it was cheesy,

However the next day I found ones ~5-8 m away that didn't seem associated with those roots
