Oligotrophic fungi from a carbonate cave, with three new species of Cephalotrichum
Oligotrophs are microorganisms that can grow in environments where concentrations of nutrients are low or even absent. Caves are typical oligotrophic environments distinctly characterised by constant low temperature, high humidity, scarcity of organic matter and darkness, which encompass a high dive...
