What is Porodaedalea anyway? Jessie A. Glaeser and Karen Nakasone Center of Forest Mycology Research Northern Research Station, Madison, WI Biosystematics Studies Goal: to create a system hierarchy that reflects evolution and provides instant information about a fungus. Create monophyletic groups - arising from a single ancestral lineage. A Fungus of Many Names Boletus pini (1803) Cryptoderma pini (1943) Daedalea pini (1821) Fomes pini (1882) Inonotus pini (1992) Ochroporus pini (1888) Phellinus pini (1941) Polyporus pini (1825) Porodaedalea pini (1905) Trametes pini (1836) Jim Worrall The Genus Phellinus - Macroscopic Huge cosmopolitan genus. Brown, poroid, white-rot fungi, perennial, dark in KOH. Host specific or broad host range. The Genus Phellinus - Microscopic Microscopically – Dimitic hyphal system with skeletal hyphae. Often with setae. Microscopic and macroscopic morphological and physiological characteristics can be deceptive! Fiasson and Niemala - 1984 o Reassessed European o Split genus into species of Phellinus 7 genera, Morphology including Chemotaxonomy Porodaedalea. Protein electrophoresis o Europeans Nuclear conditions started using Cultural studies this name. “Numerical taxonomy” Molecular Techniques – DNA Sequencing . Sequenced 5.8S and nucLSU rDNA of Phellinus, Inonotus, other genera. .No selection pressure – changes reflect evolution. Hymenochaetoid Clade Phellinus Inonotus Trichaptum Oxyporus Hyphodontia Gilled mushrooms, polypores, toothed, corticioid fungi. Porodaedalea cluster Any Latin name is a hypothesis. Will people start to use it? Porodaedalea pini is being used in the literature! Especially in Europe but more common in U.S. A Time of Change • Major revisions among all fungal groups. • Better understanding of relationships within the fungal world and better understandings of fungal physiology and pathology..
