Family Hymenochaetaceae Imazeki & Toki

Bulletin of the Government Forest Experimental Station Meguro 67: 24 (1954)

Type: Hymenochaete Lév. 1846

This is a group of polypore brackets and poroid crusts. The brown flesh turns blackish with KOH. Molecular phylogenetics has shuffled many species among the various genera and this process is still underway. Unfortunately Index Fungorum and Mycobank have not kept up with all of the name changes and they show contradictory usage of genus names. The primary genera are listed below. The following species have been identified for Chicago Region, though some require better documentation.

  1. Asterodon
  2. Aurificaria (part of Fulvifomes?)
  3. Fomitiporella
  4. Fomitiporia
  5. Fulvifomes (F. johnsonianus, F. robiniae)
  6. Fuscoporia (F. ferruginosa?, F. gilva)
  7. Hymenochaete (H. rubiginosa, and others) [includes Cyclomyces, Hydnochaete s.s.]
  8. Hymenochaetopsis (H. olivacea, H. tabacina) [replacement for Pseudochaete]
  9. Inocutis (I. dryophila, I. rheades)
  10. Inonotopsis
  11. Inonotus (I. cuticularis)
  12. Neomensularia
  13. Onnia
  14. Phellinidium
  15. Phellinopsis (P. conchata)
  16. Phellinus (P. cf. everhartii, P. igniarius group, and unknowns)
  17. Phylloporia
  18. Porodaedalea
  19. Pseudoinonotus (P. dryadeus)
  20. Sanghuangporus
  21. Tropicoporus
  22. Xanthoporia (X. radiata) [Mensularia]
Taxonomy:
The DNA phylogeny of this clade is roughly equivalent to the previous concept for Family Hymenochaetaceae with the exclusion of Coltricia and Coltriciella. For the phylogeny and explanation of segregated genera see Wagner and Fischer (2002). Tura et al. explains why Xanthoporia with inclusion of X. radiata X. nodulosa and notably X. andersonii take priority over Mensularia. Glaeser and Nakasone (2010) explain why names change in this order.
There are three species in this family with the same epithet. Two of them were given new epithets when moved to Hymenochaete. The first species Hymenochaete tabacina (Sowerby) Lév. falls outside of the clade Hymenochaete and was given a new genus name Pseudochaete but this name is illegitimate because there was already a genus Pseudochaete for algae; in 2016 the species was transferred to Hymenochaetopsis tabacina (Sowerby) S.H. He & Jiao Yang. The second species Cyclomyces tabacinus (Mont.) Pat. appears related to Hymenochaete rather than Inonotus and thus given the new name Hymenochaete porioides T. Wagner & M. Fisch. The third species Hydnochaete tabacina (Berk. & M.A. Curtis ex Fr.) Ryvarden was renamed as Hymenochaete odontoides S.H. He & Y.C. Dai.
