Taxonomy

In a 2012 publication, Miettinen and Mario Rajchenberg introduced the name "Cinereomyces

from the Polyporaceae. 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.

Habitat and distribution

Gelatoporiaceae fungi are saprophytic, and cause white-rot in coarse woody debris. Many of the species have been reported frequently from burned wood, although none absolutely require it as a
