The Tender Nesting Polypore (Hapalopilus rutilans) is a decomposer of wood which is common on fallen Hickory (Carya sp.). It can be found from the spring through the fall. The cap is colored orangish to brownish and does not have a stem (sessile). There are angular pores underneath the cap. A distinctive feature of this mushroom is the vivid purple color that is displayed when a drop of KOH or Ammonia is applied on the surface (both are strong chemical bases that change the pigmentation).

Also known as Hapalopilus nidulans.

Ethnomycology

Due to this mushroom's vibrant colors in combination with chemicals, it is a common source of pigment for dying natural fibers (yarn, thread, etc.) making it a valuable mushroom for mycocrafting. (Bloom & Dye, 2024)
