Resupinate polypore on Pinus rigidus. Park. Growing again on old self. 4-6 pores per mm. Pores have a sugary aspect. When younger pores are white and at maturity they take a grayish color. It has a stink bug smell. Skeletocystidia of various widths ~ 4.9 um. A second type of hypha was seen 2.4 um wide, with simple septa. No spores or basidia spotted.

Fruiting on top of a cut hardwood- oak, honey locust and cottonwood in the canopy.

Elevation: 1500ft.

Temp: mid 60’s.

UPDATED 3/26/15-New images of this aged, blackened sporophore in situ below(approximately 5 months from the original post).

Location: Cottonwood creek bottom, 10 mile creek near Spring Meadow State Park

Weather: Cold, 27*F, mostly clear and still, back waters are icing up

Habitat: grassy creek bottom, forested with cottonwoods

Substrate: Populus angustifolia log

Nearby Species: P. angustifolia, P. trichocarpa, Rosa sp., graminoids, Verbascum thapsus, sharing log with Daedaleopsis confragosa.

Phenology: rose hips present, no non-polypore fruiting bodies found, many plants still have green leaves despite the cold temps, maybe they were frozen too early?

Features: perrenial, very firm, almost rubbery, pores mostly circular but some irregular, white spores, KOH- or slightly brown, slightly pleasant odor, no red banding

Huge resupinate polypore on a giant hollow deciduous tree. Gloeocystidia present and several types of cystidia. No spores or basidia seen. KOH turned it some sort of brown. Even touching it bruised it. Exudation present. Velutinous aspect of pores and margin. 1 pore per mm. Very fragrant smell. Park.

2 pores per mm. Flesh is marbled. Polypore seems perennial. Lighter tones of flesh fill up space between layers of pores. KOH turned dark brown-honey pore surface. Cap surface is not cottony but appressed chocolate hyphae. Its aspect reminds of cliffs or rock formations that are eroded. The tallest cap was 2.3 cm. Caps look like miniature hooves. Spores ~ 10.2-12.8 x 3.8-5.1 um. Skeletocystidia ~3.8 um wide and some kind of cystidia with broader tip and simple septa with thick walls. Clamps were seen. Melzer reaction amyloid. On beech. Park.

Growing on a Pinus twig. All structures inamyloid. Generative hyphae clamped. Lamprocystidia abundant in the spines. Spores smooth, inamyloid and thin-walled. Spore measurements: (3.7) 3.9 – 4.7 (5) × (1.6) 1.7 – 2.5 (2.9) µm, Q = (1.6) 1.65 – 2.6 (2.7); N = 22, Me = 4.3 × 2.2 µm; Qe = 2
