Phaeobotryon negundinis sp. nov. (Botryosphaeriales) from Russia

Abstract

A new species of Phaeobotryon was collected from Acer negundo, Forsythia × intermedia and Ligustrum vulgare from European Russia. Morphological and phylogenetic analyses of combined ITS, β-tubulin and EF1-α sequence data revealed that these collections differ from all other species in the genus. Therefore it is introduced here as Phaeobotryon negundinis sp. nov. It is characterized by immersed-erumpent, uniloculate conidiomata, bearing brown, ovoid, aseptate conidia, with broadly rounded apices and truncate bases. Conidia form a single septum at germination. Phaeobotryon negundinis is morphologically similar to P. cupressi, but has smaller conidia. This is the first time a Phaeobotryon species is reported on Acer negundo, Ligustrum vulgare and Forsythia × intermedia.

Identification of endophytic fungi from leaves of Pandanaceae based on their morphotypes and DNA sequence data from southern Thailand

“…Botryosphaeriales is a diverse order with a worldwide distribution, comprising species that vary from endophytes to pathogens (Slippers and Wingfield 2007; Phillips et al 2013; Chethana et al 2016; Daranagama et al 2016; Dissanayake et al 2016; Konta et al 2016a, b; Linaldeddu et al 2016a, b, c; Manawasinghe et al 2016; Zhang et al 2017). Currently, nine families are recognised, namely, Aplosporellaceae, Botryosphaeriaceae, Endomelanconiopsisaceae, Melanopsaceae, Phyllostictaceae, Planistromellaceae, Pseudofusicoccumaceae, Saccharataceae and Septorioideaceae (Schoch et al 2006; Minnis et al 2012; Wikee et al 2013; Slippers et al 2013; Wyka and Broders 2016; Dissanayake et al 2016; Yang et al 2017).…”

“…The order Botryosphaeriales was introduced by Schoch et al (2006) with Botryosphaeriaceae as the type family. Botryosphaeriales is a diverse order with a worldwide distribution, comprising species that vary from endophytes to pathogens (Slippers and Wingfield 2007;Phillips et al 2013;Chethana et al 2016;Daranagama et al 2016;Dissanayake et al 2016;Konta et al 2016a, b;Linaldeddu et al 2016a, b, c;Manawasinghe et al 2016;Zhang et al 2017).

Morphology and molecular analyses reveal three new species of Botryosphaeriales isolated from diseased plant branches in China

“…However, both the Phaeobotryon aplosporum observed in this study and the one described by Pan et al (2019) have pigmented but without septa. Phaeobotryon rhoinum also shows pigmented and aseptate conidia ( Daranagama et al 2016 ). Other species of Phaeobotryon with pigmented and septate conidia are either saprobic or pathogenic, but Ph.…”
