Genus Gloeoporus Mont.

[separate from Gelatoporia]

Effused or effused-reflexed poroid crust with a separable gelationous pore layer that stretches when fresh. Jung et al. (2018) have established the following species in Gloeoporus, but did not mention Gl. ambiguus.

  1. Gloeoporus africanus, Africa.
  2. Gloeoporus ambiguus, throughout North America.
  3. Gloeoporus citrinoalbus, tropical China.
  4. Gloeoporus dichrous, Cosmopolitan, but reports from tropics may be other species.
  5. Gloeoporus hainanensis, tropical China.
  6. Gloeoporus orientalis, Asia.
  7. Gloeoporus pannocinctus, circumpolar, across North America, less common in Europe.
  8. Gloeoporus thelephoroides, Pantropic, South America, widespread in Africa. Distribution in North America unknown because of synonymy errors and missapplied names before 1970 (very few recent records); known for Florida.

Dispostion of some other taxon names.

  1. Gloeoporus adustus ==> Bjerkandera adusta.
  2. Gloeoporus amorphus ==> Skeletocutis amorpha.
  3. Gloeoporus crispus ==> Bjerkandera adusta.
  4. Gloeoporus fumosus ==> Bjerkandera fumosa.
  5. Gloeoporus taxicola ==> Meruliopsis taxicola.
  6. Gloeoporus cystidiatus ==> Meruliopsis cystidiata.
  7. Gloeoporus guerreroanus ==> Meruliopsis cystidiata.

Taxon Details and Links

  • Gloeoporus Mont., Annales des Sciences Naturelles Botanique 17: 126 (1842). Type: Gloeoporus conchoides Mont., Annales des Sciences Naturelles Botanique 17: 126 (1842); a later synonym of Boletus thelephoroides Hook., Synopsis Plantarum 1: 10 (1822).
The other members of this group require DNA phylogeny work to determine who stays and who goes. The species M. taxicola is the type for Meruliopsis, a genus separate from Gloeoporus. Gloeoporus dichrous is confirmed to be a Gloeoporus and it is not in Gelatoporia.
Gloeoporus has a continuous hymenial layer over the pores, a feature shared with some other phlebioid taxa, unlike Gelatoporia subvermispora that has differentiated dissepiment edges (tube mouths). This feature is part of the reason Niemelä (1985) could not place Ge. subvermispora in Gloeoporus.
My comments previously, before 2018: The phylogenetic work of Binder et al. (2013) and earlier papers shows Gelatoporia subvermispora (type species of that genus) to be outside the phlebioid clade far removed from Gl. taxicola and Gl. dichrous. Justo et al. (2017) made Gelatoporiaceae. However Gl. dichrous is not apparently directly related to Gl. taxicola but instead next to Gloeoporus pannocinctus (another taxon that cannot be kept in Gelatoporia). This was pointed out in Rajchenberg (2011, p. 696). Further work is needed to sort out relationships. The type species for Gloeoporus, Gl. thelephoroides, needs to be included in DNA phylogenies to see its placement.
