Order Hymenochaetales Oberw.

Beiträge zur Biologie der niederen Pflanzen: 89 (1977)

Type: Hymenochaete Lév. 1846

This is a diverse group of polypores and related fungi. Many of the members are brown-fleshed polypores that turn blackish with KOH. The brown poroid Phellinus and Inonotus types are in the Hymenochaetaceae family. The rest of the members are in several smaller clades that are not well defined and family limits are not set.

  1. Hymenochaetaceae clade
  2. Residual clades
    • Coltricia and Coltriciella (position unresolved)
    • Schizoporaceae, includes Xylodon (Schizopora) and Lyomyces (was part of Hyphodontia)
    • Tubulicrinaceae or Hyphodontia clade (s.s.), includes Tubulicrinis
    • Kneiffiella clade (was part of Hyphodontia)
    • Rickenella clade, includes Peniophorella, many other genera, and Repetobasidiaceae
    • Oxyporus clade, includes Botryodontia
    • Residual genera: Basidioradulum, Cyanotrama, Fibricium, Poriodontia, Trichaptum
DNA phylogenies have shown the traditional families to be artificial. There are some surprising members of this group, such as the small gilled mushroom Rickenella. There are no morphological features that unite this order and exclude fungi outside the order. Glaeser and Nakasone (2010) explain why names change in this order.
Hyphodontia, in the broad sense, was spread over four or more clades. The type species Hyphodontia pallidula is in a clade with Tubulicrinis. Hyphodontia (1958) is a conserved name but not against the earlier Tubulicrinis (1956; it is not rejected). The family Tubulicrinaceae (1982) also apparently has priority over Hyphodontiaceae (1996).
