Observation 191557: Hebeloma (Fr.) P. Kumm.
When: 2014-11-26
No herbarium specimen

Notes: Biggest Hebeloma I’ve ever seen. Described and dried for future donation to Henry Beker’s Hebeloma insanity project.

Pileus: 5.5cm-14cm in diam, glabrous to slightly greasy; cream to light tan with some faint rosy/blushing areas; broadly convex to uplifted in age; margin inrolled when young/fresh, exceeding lamellae minutely at maturity; context white, up to 1.5cm thick at center, tapering toward margin; some FBs with a gelatinus, clear, subhymenial later just beneath gills (≤ 1mm thick); flesh delicate, breaking cleanly; odor and taste mildly raphanoid, fresh.

Lamellae: broadly adnate to adnexed to receeding at maturity; closely spaced; up to 1.3cm in breadth; edges uneven/undulating but otherwise undifferentiated; lamellulae in ~3-4 series; pale whitish to pinkish brown to tobacco brown at maturity; spores tobacco brown in deposit.

Stipe: ~1cm-2.5cm thick x ~9cm-15cm long; centrally attached; equal with slightly to moderately enlarged base (~1.6cm-3cm); straight or slightly curved, often “hooking” just above the base; longitudinally striate with scattered brown fibrils along lower two thirds and fine, appressed, white, cottony flecks along upper third; pearlescent white/off-white overlaid with said fibrils and dingy yellow brown areas which darken with handling and age; context pearlescent white, fibrous, stuffed (?); considerably firmer in consistency than pileus tissue.

Habit(at): growing singly or in clusters of two to eight in soil beneath Douglas fir, Oregon grape, madrone, incense cedar, black oak and ponderosa pine.
