Amphichorda monjolensis sp. nov., a new fungal species isolated from a Brazilian limestone cave, with an update on acremonium-like species in Bionectriaceae

Multi-locus molecular phylogenetic analysis reveals two new species of Amphichorda (Bionectriaceae, Hypocreales)

“… monjolensis were found in caves, especially A. felina , which was widely distributed in caves ( Vanderwolf et al 2013 ; Zhang et al 2017 , 2021 ; Vanderwolf et al 2018; Leão et al 2024 ). Amphichorda littoralis was found in Mediterranean coast sediments at 20 m depth ( Guerra-Mateo et al 2023 ).…”

“…However, Guerra-Mateo et al (2023) conducted the phylogenetic analysis based on the nuclear ribosomal internal transcribed spacer region ( ITS ) and the nuclear ribosomal large subunit (nr LSU ), considered Amphichorda to belong to the family Bionectriaceae and determined Amphichorda has close phylogenetic relationships with the genera Hapsidospora and Nigrosabulum . Leão et al (2024) also proving the genus Amphichorda belongs to the family Bionectriaceae .…”

“…The DNA sequences newly generated have been submitted to GenBank. The sequences downloaded from the GenBank database were based on a previous study by Hou et al (2023) and Leão et al (2024) . The taxonomic information and corresponding GenBank accession numbers used are provided in Table 1 .…”

“…Fr., which was isolated from cat dung and previously classified in the genus Clavaria ( Lamarck 1815 ; Fries 1825 ). At the present, seven species of the Amphichorda are now validly published ( Zhang et al 2017 , 2021 ; Guerra-Mateo et al 2023 ; Liu et al 2023 ; Leão et al 2024 ). The traditional phylogenetic placement of the genus Amphichorda was considered in the family Cordycipitaceae ( Hypocreales ).…”
