Loweomyces is a genus of six species of poroid fungi in the family Steccherinaceae (formerly placed in the Meruliaceae).[2]

Taxonomy[edit]

It was originally circumscribed as a subgenus of Spongipellis by the Czech mycologists František Kotlaba and Zdeněk Pouzar in 1976.[3] Swiss mycologist Walter Jülich promoted it to a genus segregate from Spongipellis in 1982, with two species: L. fractipes (the type), and L. wynneae. Jülich thought the genus should be distinct from Spongipellis based on the larger basidia, the absence of skeletal hyphae, and smaller tubes.[4] L. fractipes and L. wynneae have had their generic positions confirmed with molecular phylogenetics, and both group in the "residual polyploid clade", one of four main lineages of the Polyporales.[2][5] The genus is named in honour of American mycologist and polypore specialist Josiah Lincoln Lowe.[6]

Description[edit]

Loweomyces is distinguished by the ease of spore germination in growth media, larger basidia, the absence of skeletal hyphae, and smaller tubes, plates or spines, compared with European Spongipellis species.[4] Fruit bodies are either crust-like or have a cap and stipe. The hyphal system is either monomitic (possessing only generative hyphae) or dimitic (having both generative and pseudo-skeletal hyphae).[7]

Species[edit]

The genus contained four species as of January 2015.[8] Two new species from Brazil were described in 2016.[7]
