A phylogeny for the plant pathogen Piptoporellus baudonii using a multigene data set

Abstract

Piptoporellus baudonii is proposed as a new combination for Laetiporus baudonii in the Polyporales (Basidiomycota) based on morphological and molecular features. This parasitic macrofungus attacks cashew trees, Eucalyptus, cassava, Tectona, and some indigenous trees in southern regions of Tanzania and poses a serious threat to agroforestry and livelihood conditions in the area. Phylogenetic trees were produced from partial sequences of three rDNA gene regions and a portion of translation elongation factor 1-alpha (TEF1) gene of Laetiporus baudonii for comparisons with samples from the antrodia clade. Our results reveal a strongly supported group of L. baudonii with Piptoporellus in Fomitopsidaceae. Piptoporellus baudonii shares many morphological features with other members of Piptoporellus but differs from them in having broadly ellipsoid or rarely ovoid basidiospores. Both morphological and phylogenetic evidence justify the placement of L. baudonii in Piptoporellus together with the three other known species in the genus.

Neotropical Daedalea (Basidiomycota, Fomitopsidaceae) revisited: Daedalea rajchenbergiana sp. nov. from Brazil

“…Bayesian and ML analyses resulted in identical topologies; the Bayesian consensus tree is presented in Figure 1. The topology recovered in our phylogenetic analyses is in general congruent with previous works regarding the 'antrodia' clade (Han et al, 2015(Han et al, , 2016Tibuhwa et al, 2020;Decock et al, 2022). Thirteen main strong supported lineages at genus level were recovered: Fibroporia (1/100), Piptoporellus (1/100), Antrodia s. s. (1/100), Buglossoporus (1/100), Fragifomes (1/100), Rhodofomes (1/100), Niveoporofomes (1/100) Neoantrodia (1/100), Brunneoporus (1/100), Ungulidaedalea, Rhodofomitopsis (1/100), Fomitopsis (1/100) and Daedalea (0.97/90).…”

New records and barcode sequence data of wood-inhabiting polypores in Benin with notes on their phylogenetic placements and distribution

“…Distribution: Widespread in Tropical Africa (Ryvarden & Johansen 1980;Tibuhwa et al 2020). Reported from Burkina-Faso (Guissou et al 2008) and first record in Benin.…”
