Genus Lopharia Kalchbr. & MacOwan

in Kalchbrenner, Grevillea 10(no. 54): 58 (1881)

Type species: Lopharia lirellosa Kalchbr. & MacOwan, Grevillea 10 (54): 58 (1881); a later synonym of Radulum mirabile Berk. & Broome, J. Linn. Soc., Bot. 14(no. 73): 61 (1873); ≡ Lopharia mirabilis (Berk. & Broome) Pat., Bulletin de la Société Mycologique de France 11: 14 (1895)

Lopharia are stereoid fungi, effused-reflexed or resupinate, with dimitic hyphal system, generative hyphae with clamps, and hymenium with large encrusted thick-walled cystidia. The upper surface, when present, is velvety to tomentose. The hymenium is smooth or sometimes with bumps or teeth or with somewhat shallow pores. With some species transferred to Hjortstamia, Phanerochaete and Porostereum, this genus is now treated in a more restricted sense. Lopharia cinerascens is a widespread species in USA and Canada. There is a record of Lopharia rugulosa in California. There are other species in Mexico and the tropics.

  1. Lopharia cinerascens is a stereoid crust with hairy upper surface.
Taxonomy:
The genus Lopharia has been classified in the Phanerochaetaceae and the Stereaceae, but is currently in the Polyporaceae. If that family gets split up, there is another legitimate family name available: Lophariaceae Boidin, Mugnier & Canales 1998. Binder et al. 2013 says that the clade comprised of Lopharia cinerascens and Dentocorticium sulphurellum is very likely the earliest diverging lineage in the core polyporoid clade; this is outside of the trametoid clade, which is Trametes in the sense of Justo and Hibbett (2011), and the large polyporus clade.
