<p><strong><em>Ganoderma bambusicola</em></strong><strong> sp. nov. (Polyporales, Basidiomycota) from southern Asia</strong></p>

Abstract

Ganoderma bambusicola sp. nov. is described and illustrated from tropical Taiwan; it is also found in Laos and Myamar. The species is recognized as new based on morphological study and phylogenetic analyses using three gene regions: ITS, rpb2 and tef1-α. Ganoderma bambusicola has been incorrectly identified as G. neojaponicum in Taiwan for several decades on account of it having a similar shiny dark reddish brown to purplish black pileus surface and a blackish long stipe, but it differs from the latter species in having a homogeneous pileal context. Ganoderma bambusicola is, to date, only known from southern Asia and grows on bamboo roots, while G. neojaponicum occurs on roots or trunks of conifers in Japan, China and Korea. These two species do not have a close relationship according to the present phylogenetic study.

Phylogenetic analyses and morphological characters reveal two new species of Ganoderma from Yunnan province, China

“…It is easy to distinguish them from the morphological characteristics. Gano-derma bambusicola has a longer pileipellis (35-65 × 8-16 μm) and wider basidiospores than those of G. esculentum (10.0-13.0 × 6.5-8.0 μm, Wu et al 2020). Ganoderma aridicola can be easily distinguished from G. esculentum by the sessile basidiomata and a fuscous to black pileus surface (Xing et al 2016).…”

“…Species diversity of Ganoderma is abundant in China and more than 30 species have been described (Zhao et al 2000;Wang et al 2009;Cao et al 2012;Li et al 2015;Xing et al 2016;Hapuarachchi et al 2018;Liu et al 2019;He et al 2019;Wu et al 2020). Yunnan province is considered as one of the hot-spots for studying biodiversity of polypores, and some new Ganoderma species have been described (Zhao 1989;Wang et al 2010;Cao and Yuan 2013).…”

Taxonomy and phylogeny of Sanguinoderma rugosum complex with descriptions of a new species and a new combination

“…Besides, the rise of species diversity is impressive but uneven. Ganoderma , as the biggest genus in this family, has expanded to 188 species based on credible morphological and phylogenetic evidence; however, the sum of species number of the other 13 genera is only half of that of Ganoderma (Ryvarden, 2020 ; Wu et al, 2020 ; Decock and Ryvarden, 2021 ; He et al, 2022 ; Sun et al, 2022b ; Vinjusha and Kumar, 2022 ).…”
