A new species of Globulisebacina from Taiwan and new record of Chaetospermum camelliae with Efibulobasidium teleomorph (Sebacinales) from Panama

Abstract

Two specimens of Sebacinales from Panama and Taiwan were identified based on morphology and partial LSU rDNA sequences. A specimen on oak fruits from Panama was identified as Chaetospermum camelliae, which contained an Efibulobasidium teleomorph. Conidiogenesis in this species is classified as postsomatogamic and sympodial. For a specimen from Taiwan, a new species of Globulisebacina is described based on its placement in a molecular phylogeny of partial LSU rDNA sequences, two-celled basidia and lack of a Chaetospermum anamorph. Nomenclatural errors of two recently newly combined Sebacina species are corrected.

Competing sexual-asexual generic names in Agaricomycotina (Basidiomycota) with recommendations for use

“…Kirschner and Oberwinkler ( 2009 ) noted that conidia of C. gossypinum were associated with specimens of E. albescens , the type of Efibulobasidium , thus Chaetospermum and Efibulobasidium are most likely synonyms as accepted by Wells and Bandoni ( 2001 ) and Crous et al ( 2014 ). In addition, Chaetospermum camelliae was studied by Kirschner et al ( 2017 ) who placed its sexual morph in Efibulobasidium . Thirteen species have been accepted in Chaetospermum while only four names have been described in Ebifulobasidium , one of which has since been transferred to Globulisebacina (Oberwinkler et al 2014 ) and two of which are invalid (Kirk 2020 ).…”
