HPLC-UV profiles at 210 nm derived from stromal extracts of strains H. rubiginosum (GUM 1586), H. guilanense (from holotype) and Hypoxylon aff. rubiginosum GUM 1587 and GUM 1588. UV/Vis spectra are shown for orsellinic acid (1), mitorubrinol acetate (2), rubiginosin A (3), an unknown rubiginosin A – like derivative (URg) and rubiginosin – like derivatives (UC 2 and UC 3). ESI mass spectra are shown for compounds URg and 2.
