Cultures were prepared and maintained as described previously (Jaklitsch 2009 (link)) except that 2 % malt extract agar (MEA; 2 % w/v malt extract, 2 % w/v agar-agar; Merck, Darmstadt, Germany) was used as the isolation medium. Cultures used for the determination of growth rates and study of asexual morph micro-morphology were grown on CMD, 2 % MEA or potato dextrose agar (PDA, 39 g/l; Merck, Darmstadt, Germany) at 22–25 °C in darkness. Microscopic observations were made in tap water except where noted. Morphological analyses of microscopic characters were carried out as described earlier (Jaklitsch 2009 (link)). Data were gathered using a Nikon Coolpix 995 or Coolpix 4500 or a Nikon DS-U2 digital camera and measured with NIS-Elements D v. 3.0, or with a Zeiss Axiocam 506 colour digital camera and measured with Zeiss ZEN Blue Edition software. Methods of microscopy included stereomicroscopy using an Olympus SZ 60 or Nikon SMZ 1500 and Nomarski differential interference contrast (DIC) using the compound microscopes Nikon Eclipse E600 or Zeiss Axio Imager.A1. For certain images of ascomata the stacking software Zerene Stacker v. 1.04 (Zerene Systems LLC, Richland, WA, USA) was used. Measurements are reported as maximum and minimum in parentheses and the range representing the mean plus and minus the standard deviation of a number of measurements given in parentheses.
