Dark stains on rock surfaces in Driny Cave (Little Carpathian Mountains, Slovakia).
Mycobiota are important in underground ecology. In 2014, we discovered dark stains on clayey sediments on the walls of Driny Cave, Slovakia. Our description is based on the morphology of the fungus and the phylogenetic relationships of the internal transcribed spacer (ITS) region. In addition, data on its capacity for the production of extracellular enzymes, growth, and survival in vitro at different temperatures are reported. Our analyses revealed that this dark stains on the wall was produced by Penicillium glandicola. The fungus was able to synthesize amylases, proteases and cellulases, but not pectinases and keratinases. The vegetative structures of mycelium of this fungus are viable in vitro after storage at cool temperatures (from -72 to 5 °C), and show active growth at temperatures from 5 to 25 °C, but without spore germination, and without active growth at 30 and 37 °C. Penicillium glandicola is a psychrotolerant species and belong to var. glandicola.
