Observation 171593: Bondarzewia berkeleyi (Fr.) Bondartsev & Singer

Habitat: Found at the base of a living oak tree.

Notes: Diameter of pileus measured to be 20 cm. Stalk measured to be 5 cm while measurement of stalk and pileus was near 18 cm. Top surface of the pileus was wrinkly and white in color. Undersurface of the pileus had angular pores that are about 1.27 mm wide. The pores were elongated and some torn while getting closer to the stalk. With maturity the cap turned from whitish to brown in color. This singular fruiting body was found amongst other caps with a shelf like overlapping pattern.

Rationale for ID: This specimen was determined to be Bondarzeai berkeleyi because of the habitat, location on the tree, pores and the spore measurements. Spore print for this specimen was white and found to be 7 µm wide. Spores were round, warted and amyloid (turned blue when tested). Specimen also had a hint of odor. This specimen is also known to be found at the base of a living broadleaf tree, in this case an oak tree and in compound clusters. The angular pores underneath the pileus and the flesh turning yellow brown with age matched the morphological description of published worked.
