The Gelatoporiaceae are a small family of crust fungi in the order Polyporales. The family was circumscribed in 2017 by mycologists Otto Miettinen, Alfredo Justo and David Hibbett to contain the type genus Gelatoporia and three other related genera, Cinereomyces, Obba, and Sebipora.
In a 2012 publication, Miettinen and Mario Rajchenberg introduced the name "Cinereomyces clade" to accommodate a small group of white-rot polypores of uncertain position in the order Polyporales.[1] Further analyses confirmed that this clade represents a separate lineage from the Polyporaceae.[2][3] The genus Gelatoporia, upon which the family is based, was defined by Tuomo Niemelä in 1985 to contain poroid crust fungi with a monomitic hyphal structure, clamped hyphae, and producing white rot.[4]
Description
The fruit bodies of the Gelatoporiaceae are crust-like (resupinate), and have a poroid hymenophore. The hyphal system is typically monomitic (containing only generative hyphae), although in genus Cinereomyces it is dimitic (containing both generative and skeletal hyphae). Clamp connections are present in the hyphae. Spores made by the family are hyaline, smooth, and usually thin-walled but they are somewhat thick-walled in genus Obba. They are non-amyloid and non-dextrinoid. Cystidia are absent from the hymenium, although cystidioles may be present. The mating system is heterothallic, bipolar or tetrapolar, while the nuclear behavior is astatocoenocytic.[3]
