Taxonomy and Phylogeny of the Fomitopsis pinicola Complex With Descriptions of Six New Species From East Asia

Abstract

Fomitopsis pinicola is a common brown-rot fungal species found in northern hemisphere. It grows on many different gymnosperm and angiosperm trees. Recent studies show that it is a species complex; three species from North America and one species from Europe have been recognized in this complex. In the current study, six new species in the Fomitopsis pinicola complex were discovered from East Asia, based on morphological characters and phylogenetic analyses inferred from the sequence data of the internal transcribed spacer (ITS) regions, the second subunit of RNA polymerase II (RPB2), and the translation elongation factor 1-α gene (TEF). Detailed descriptions of the six new species are provided. Our results also indicates that species of the F. pinicola complex from East Asia usually have limited distribution areas and host specialization.

Species Diversity, Molecular Phylogeny, and Ecological Habits of Fomitopsis (Polyporales, Basidiomycota)

“…Cui & Shun Liu formed separate lineages, respectively ( Figure 1 ). In addition, the current phylogenetic analyses also showed that Fomitopsis and other related brown-rot fungal genera clustered together within the antrodia clade, which are consistent with previous studies ( Ortiz-Santana et al, 2013 ; Han et al, 2016 ; Liu et al, 2019 , 2021a ; Zhou et al, 2021 ).…”

“…Subsequently, phylogenetic analyses indicated that Fomitopsis is polyphyletic and the taxonomic position of Fomitopsis is still problematic ( Kim et al, 2005 , 2007 ; Justo and Hibbett, 2011 ; Ortiz-Santana et al, 2013 ). Recently, taxonomic and phylogenetic studies on Fomitopsis have been carried out and several new species have been described ( Li et al, 2013 ; Han et al, 2014 , 2016 ; Han and Cui, 2015 ; Soares et al, 2017 ; Haight et al, 2019 ; Liu et al, 2019 , 2021a ; Zhou et al, 2021 ). Han et al (2016) investigated phylogenetic relationships of Fomitopsis and its related genera and reported that species previously placed in Fomitopsis were divided into seven lineages: Fomitopsis s. s., Fragifomes B.K.…”

Two new brown rot polypores from tropical China

“…The phylogeny of Oligoporus, combined 7-gene (ITS, nLSU, nuSSU, mtSSU, RPB1, RPB2, TEF1) dataset, included sequences from 43 fungal samples representing 21 taxa. They were downloaded from GenBank and generated in the present study ( Liu et al (2021) were variable and parsimony-uninformative and 1516 were parsimony informative. Maximum parsimony analysis yielded four equally-parsimonious trees (TL = 3925, CI = 0.600, RI = 0.784, RC = 0.471, HI = 0.400) and a strict consensus tree of these trees is shown in Fig.…”

“…Soares & Gibertoni was proposed as a new combination ( Soares et al 2017 ; Tibpromma et al 2017 ; Liu et al 2019 ). In the latest study, ten species have been recognised in the Fomitopsis pinicola complex ( Haight et al 2019 ; Liu et al 2021 ). So far, 25 species have been accepted in Fomitopsis sensu stricto (s.…”

Taxonomy and Phylogeny of the Favolaschia calocera Complex (Mycenaceae) with Descriptions of Four New Species

“…The PCR cycling schedules for different DNA sequences used in this study followed those used in Zhou et al and Liu et al [23,24] with some modifications. The PCR procedure for ITS, mt-SSU, and TEF1 was as follows: initial denaturation at 95 • C for 3 min, followed by 35 cycles at 94 • C for 40 s, 54 • C for 45 s, and 72 • C for 1 min, and a final extension of 72 • C for 10 min.…”
