Flavomyces D.G. Knapp, Kovács, J.Z. Groenew. & Crous, Persoonia 35: 93 (2015).

Index Fungorum number: IF 810758; Facesoffungi number: FoF 06659, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.

Endophytic in roots. Colonies covering the Petri dish after 2 weeks at 24 °C. Colonies on MMN submerged, white to pale yellow with sparse hyaline aerial mycelium, with diffuse pale yellow-eosine pigment forming in media. After years of storage the ability to stain the medium can be lost and colonies become flat with lobate marginal zone. Colonies on MEA submerged, white with more aerial hyaline mycelium (Adapted from Knapp 2015).


Type species: Flavomyces fulophazii D.G. Knapp, Kovács, Groenewald & Crous


Notes: Flavomyces was introduced by Knapp (2015) with F. fulophazii as type species. Flavomyces lacks a complete morphological character as it is a root endophyte and is known only from cultural or hyphal morphology. Flavomyces is characterized by white to pale yellow hyphae which diffuse aerial mycelium, with diffuse pale yellow-eosine pigment in MMN media. On maturity, the hyphae lose ability to diffuse pigment. on MEA, the hyphae are more hyaline.  Flavomyces is a distinct genus in Periconiaceae. Molecular data available for Flavomyces are LSU and SSU.
