“…A large number of names synonymous with P.umbrina have been illegitimately or superfluously published. Fries himself (1847), as well as Quélet (1888) and Burt (1916), seem to have overlooked Wallroth’s (1833) combination of Hypochnusumbrinus (Alb. & Schwein.)…”

“…Our interpretation of Thelephoraumbrina Fr. as the basionym follows Burt (1916), Litschauer (1933), Svrcek (1958) and Larsen (1967), although Rogers and Jackson (1943) considered it to be a synonym of Coniophoraolivacea . The name is not used here in the sense of what we today interpret as C.olivacea , but in the sense of Burt’s (1916) type selection.…”

P.tristis is an ectomycorrhizal, corticioid fungus whose name is frequently assigned to collections of basidiomata as well as root tip and soil samples from a wide range of habitats and hosts across the northern hemisphere. Despite this, its identity is unclear; eight heterotypic taxa have in major reviews of the species been considered synonymous with or morphologically similar to P.tristis, but no sequence data from type specimens have been available. With the aim to clarify the taxonomy, systematics, morphology, ecology and geographical distribution of P.tristis and its morphologically similar species, we studied their type specimens as well as 147 basidiomata collections of mostly North European material. We used gene trees generated in BEAST 2 and PhyML and species trees estimated in STACEY and ASTRAL to delimit species based on the ITS, LSU, Tef1α and mtSSU regions. We enriched our sampling with environmental ITS sequences from the UNITE database. We found the P.tristis group to contain 13 molecularly and morphologically distinct species. Three of these, P.tristis, P.umbrina and P.atrofusca, are already known to science, while ten species are here described as new: P.sciastrasp. nov., P.tristoidessp. nov., P.umbrinascenssp. nov., P.pinophilasp. nov., P.alnophilasp. nov., P.alobatasp. nov., P.plurilobasp. nov., P.abundilobasp. nov., P.rotundisporasp. nov. and P.mediasp. nov. We discovered P.rhizopunctata and P.atrofusca to form a sister clade to all other species in P.tristis s.l. These two species, unlike all other species in the P.tristis complex, are dimitic. In this study, we designate epitypes for P.tristis, P.umbrina and Hypochnopsisfuscata and lectotypes for Auriculariaphylacteris and Thelephorabiennis. We show that the holotype of Hypochnussitnensis and the lectotype of Hypochnopsisfuscata are conspecific with P.tristis, but in the absence of molecular information we regard Pseudotomentellalongisterigmata and Hypochnusrhacodium as doubtful taxa due to their aberrant morphology. We confirm A.phylacteris, Tomentellabiennis and Septobasidiumarachnoideum as excluded taxa, since their morphology clearly show that they belong to other genera. A key to the species of the P.tristis group is provided. We found P.umbrina to be a common species with a wide, Holarctic distribution, forming ectomycorrhiza with a large number of host species in habitats ranging from tropical forests to the Arctic tundra. The other species in the P.tristis group were found to be less common and have narrower ecological niches.

“…Christiansen's T. luteomarginata is based on a mature and well formed specimen of T. microspora; the most striking difference between nomenclatural types of the two names is the larger spore size of T. luteomarginata. Burt's (1916) MAcRoscoPIc-Basidiocarps annual, resupinate, effused up to 5 X 3 cm, up to 0.5 mm thick, arachnoid, somewhat adherent to becoming separable; fertile areas discontinuous, dull pinkish buff (near 5.0 YR 6/6); hymenial surface smooth to mostly granulose; subiculum scanty, arachnoid, paler than the fertile areas; margin narrow, arachnoid, paler than the fertile areas. MIcRoscoPIc-Hyphal system monomitic.…”
