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 PSN332 since it does not produce sexual structures in culture. It is likely heterothallic and PSN332 needs thus to be mated to a compatible isolate to reproduce sexually. Cladorrhinum species are frequent in soil, especially those of organic gardens. ITS sequencing showed that PSN332 is distantly related to “Cladorrhinum bulbillosum” and “Podospora fimicola”. The sequenced strain Cladorrhinum sp. PSN332 has been isolated from soil collected in an organic garden in Amiens, France.
