Id is a guess
Resupinate-hydnoid white fungus on oak wood in mixed forest. Hymenium white to tan, densely toothed.
Growing on Pseudotsuga menziesii wood. Orange, fuzzy resupinate crust with racing mycelium.
Duff-dwelling mushroom in Hesperocyparis sargentii forest. Pileus wavy-planar, silky greyish brown. Lamellae light pinkish beige, narrowly attached. Stipe whitish-beige, fibrillose.
Growing on plum tree in garden. White and tan zonate pileus with different bands of hair, furled upward to the attachment points forming a semi cone. Hymenium consisting of light tan pores.
Growing on well-rotted Pseudotsuga menziesii wood. Resupinate white fungus with irregular, mazelike pores and transparent guttation.
Growing on wood in log jam. Pileus broadly convex, brown, darkest at the umbo, mottled-hygrophanous. Lamellae burnt umber brown, widely attached. Stipe off-white, fragile, contorted and twisted up.
On the oak that fell in Feb 2022. Very soft, flexible. No taste. Spore print brown. . . spores smooth, very light brown in KOH . . . length range 7.7 to 10 microns, mean 8.5 width range 5 to 6.6 mean 5.4 Q = 1.57 "ellipsoid" This squares with Kuo's description for C calolepis "spores 7–10 x 5–6 µm; ellipsoid to subamygdaliform; virtually smooth; yellowish to brownish in KOH." Kuo cautions that C. mollis is so like C. calolepsis that they can only be told apart by microscopy that I can't do. Therefore I will hold at the Genus level where Sigrid had left it.
In Pinus jeffreyi and Calocedrus decurrens forest on ultramafic soil. Pileus grey-scaly, upturned at margins. Lamellae white, free. Stipe white, widest at the base.
Tan clitocyboid mushrooms in leaf litter under Sequoia sempervirens and Notholithocarpus densiflorus. Pileus depressed, tacky-shiny, light tan. Lamellae whitish, decurrent. Stipe whitish, fibrous, with copious thick white rhizoids extending from base.
Growing from Pinus ponderosa leaf litter in lightly burned forest. Pileus umber-ochre brown, hygrophanous, hemispheric. Lamellae narrowly attached, brown, lightest at the margins. Stipe whitish-silvery-brown, widest at base
