The sequenced strain of Cladorrhinum sp. PSN259 was isolated from soil collected near Picos de Europa in Spain. Cladorrhinum was initially defined as an asexual genus, but recently it was re-attributed to some species of the Podosporaceae family, including sexual ones, while the Podospora genus was attributed to other species from a distinct lineage. However, there is an ongoing proposal to change the type of Podospora, which will impact nomenclature of Podosporaceae. Pending resolution of the actual type for Podospora, Cladorrhinum has thus been kept to name isolate PSN259 since it does not produce sexual structures in culture. PSN259 is likely heterothallic and thus needs to be mated to a compatible isolate to reproduce sexually. Cladorrhinum species are frequent in soil. ITS sequencing showed that PSN259 is distantly related to Cladorrhinum australe.
