Genus Hapalopilus P. Karst.

[related to Phaeophlebiopsis and Rhizochaete]

Gilbertson and Ryvarden (1986) describe five species for North America, but all but H. rutilans have been excluded from the genus based on DNA analysis and three other species added by Miettinen et al. (2016). Polyporic acid makes these species poisonous. The reaction with KOH is reddish to violet, also seen in the related Rhizochaete.

  1. Hapalopilus eupatorii, temperate Europe
  2. Hapalopilus percoctus, Botswana
  3. Hapalopilus ribicola, North Europe
  4. Hapalopilus rutilans (H. nidulans ), holarctic, fairly common in Midwest.

Taxonomy
Tradition places it in the Polyporaceae but DNA phylogenies reveal it is in the phlebioid clade. Hapalopilus croceus is now Aurantiporus croceus in the Meruliaceae.
