Genus Merulius Fr.

[A separate genus from Phlebia]

Most authors combine Merulius under Phlebia but Binder et al. (2013) and Justo et al. (2017) provide evidence to keep the genera separate. The smallest clade having both Merulius tremellosus and Phlebia radiata also contains Aurantiopileus (three species), Aurantiporus (six to nine species) and the ophan Ceriporiopsis pseudoplacenta. Either we recognize several genera are we lump them under Phlebia.

Merulius tremellosus is a common species. Justo et al. (2017) and Kuuskeri et al. (2015) show species related to Merulius tremellosus; these are listed below. Nakasone & Burdsall (1995) describe P. hydnoidea and P. nantahaliensis (I could not find images for them).

  1. Merulius hydnoideus (Phlebia hydnoidea, Odontia lateritia, eastern and southeastern USA)
  2. Merulius tremellosus (widespread)
  3. Phlebia leptospermi (New Zealand; bright yellow when fresh)
  4. Phlebia nantahaliensis (North Carolina)
  5. Phlebia serialis (Canada, Northern Europe)

Nomenclature
  • Genus Merulius Fr., Systema Mycologicum 1: 326 (1821)
Type
Merulius tremellosus Schrad. 1794.
Taxonomy
Merulius tremellosus is the type for Merulius as it was the first species given by Fries. The concept of Merulius by Fries (1821) is conserved over the earlier Merulius Haller ex Boehm. (1760), which had as type Agaricus cantharellus L. (≡ Cantharellus cibarius).
