Description
Sanghuangporus weirianus is a parasite and decomposer of Black Walnut (Juglans nigra) and can be found year-round. The top of the cap is black with fissures that look similar to the way bark splits on a tree. This conk is hard, perennial, and exclusively favors Walnut (Juglans). The top of the cap is black, and the bottom pore surface is cream to orange-brown with tiny pores with an iridescent shine. It has a pale-yellow spore print.
Also known as Phellinus weirianus.
Compare to Fulvifomes robiniae which grows on Black Locust (Robinia pseudoacacia).

#145
Two separate specimens growing about 12 ft up on large Black Walnut tree on north-facing oak woodland slope near woodland edge.
Hymenium iridescent. Orange-brown. Pores small. Bruises dark brown.
Smell: Strong earthy and sweet. Taste: Faintly bitter.
Spore print: pale yellow.
KOH: Instantly black on all surfaces. Ammonia: Instantly reddish brown on fresh hymenium and black on other surfaces.
Microscopy: Spores and hyphal tissues dextrinoid in KOH. Spores appear to be somewhat red blood cell-shaped, some more sickled then others (see 3rd microscopy photo).
