Observation 219856: Ischnoderma resinosum (Schrad.) P. Karst.
When: 2015-10-10
No herbarium specimen

Notes: Two overlapping fruit bodies growing on a very soggy downed log. The specimens were fresh, moist, and fleshy. Largest specimen was 10 cm. across and 2 cm. thick at the base. Upper surface felt-like, concentrically zoned shades of black and rusty browns with black resinous deposits in the ridges and near point of attachment, ridged and wrinkled. Rim of bracket is white, thick, and rounded. Pore surface initially whitish but instantly bruised brown upon handling. This specimen was found during a MOMS foray and handled by many as you can tell from the photo of the fertile surface. 4 round pores per mm. Flesh soft, moist, pale buff or light cinnamon. KOH black on upper and pore surfaces after about 1 minute. Please see photo captions for additional info.
