High-Resolution LC-MS Characterization of Ramaria flavobrunnescens, a Coral Mushroom Toxic to Livestock, Reveals Fungal, Bacterial, and Eucalyptus Tree Metabolites.

ABSTRACT: Ramaria flavobrunnescens is an ectomycorrhizal coral mushroom that is often found growing in eucalyptus forests. The mushroom has been linked to accidental ingestion-associated livestock poisonings in South America, though the toxicological agent has not yet been described. Mushroom samples identified as R. flavobrunnescens were analyzed by liquid chromatography high-resolution mass spectrometry (LC-MS/MS) to determine the potential source of the toxicity, and to provide a metabolomic profile of the species. Previously reported Ramaria secondary metabolites were detected, including ramarins, ramariolides, pistillarin and arsenic-containing compounds. A number of bacterial species were isolated from R. flavobrunnescens that produced iron-chelating cyclic peptides
