Phialomustin A–D (1–4), four new bioactive metabolites, with an unprecedented azaphilone derived skeleton, were isolated and characterized from an endophytic fungus isolated from Crocus sativus. The ITS-5.8S-ITS2 ribosomal gene sequence of the endophyte displayed a sequence similarity of more than 99% with Phialophora mustea. The structural determinations of compounds (1–4) were authenticated by spectroscopic
