Uncovering cryptic species diversity of () associated with from Thailand.

This study advances our understanding of , an extensively studied entomopathogenic fungus within the , particularly in Thailand. We introduce seven novel species associated with - , , , , , , and . Remarkably, , , and exhibit ascomata on the subterminal region of the stromata, with the asexual form appearing at the apex of the stipe, reminiscent of .

Integrative taxonomy of Metarhizium anisopliae species complex, based on phylogenomics combined with morphometrics, metabolomics, and virulence data.

Metarhizium anisopliae (Clavicipitaceae, Hypocreales) is a globally distributed entomopathogenic fungus, which has been largely studied and used in agriculture for its potent entomopathogenicity. Since its taxonomic establishment as a member of Metarhizium, many closely related taxa have been described with highly similar morphology (cryptic species). A holotype specimen of M.

Novel species of fungi described in this study include those from various countries as follows: , in leaves of , among deep leaf litter, from uredinium of on , on well-rotted twigs and litter in mixed wet sclerophyll and subtropical rainforest. , on twigs of , on bark, in savannas with shrubs and trees. , on leaves of , (incl.

Bioactive Bioxanthracene and Cyclodepsipeptides from the Entomopathogenic Fungus BCC56290.

In the course of our ongoing research targeting the identification of potential biocontrol agents from entomopathogenic fungi (EPF), we explored a solid-state rice fungal extract of BCC56290 derived from infected lepidopteran larvae. Chemical and biological prospections afforded four unprecedentedly reported natural products differentiated into a dimeric naphthopyran bioxanthracene ES-242 derivative () and three cyclodepsipeptides (-) in addition to two known cyclodepsipeptides, cardinalisamides B () and C (). Chemical structures of the isolated compounds were elucidated through comprehensive 1D/2D NMR and HR-ESI-MS data together with comparisons to the reported literature.
