Pirex is a fungal genus in the family Meruliaceae. It is a monotypic genus, containing the single crust fungus Pirex concentricus. It is found in the Pacific Northwest region of North America, where it causes a white rot in woody hardwood and conifer debris generated by timber harvesting.[1]
Taxonomy
[edit]The species Pirex concentricus was originally described by Mordecai Cubitt Cooke and Job Bicknell Ellis in 1885 as Radulum concentricum. Ellis collected the type specimens from Oregon.[4] A century after Cooke's publication, Kurt Hjortstam and Leif Ryvarden circumscribed the new genus Pirex to contain this fungus, as they believed it to have a unique combination of traits that would not adequately fit into any other known genera. The name Pirex is an anagram of the fungal genus Irpex.[5]
In 1995, Hjortstam considered Pirex to be a synonym of Pseudolagarobasidium, and proposed the new combination Pseudolagarobasidium concentricum. Modern systematics considers the two genera to be distinct;[6] Pseudolagarobasidium is classified in the family Phanerochaetaceae. Hjortstam added Hydnum subvinosum Berk. & Broome to Pirex in 1987,[7] but this fungus is considered now a species of Radulodon.[8]
