Assessment Notes

Justification

Craterellus palmatus is a fungus species only known from western Ohio, USA, with the type collected at Oxford. This appears to be the only specimen, and there is a paucity of information regarding this species, including about the correct genus for it to be placed in. Given the high level of uncertainty and lack of information, C. palmatus is assessed as Data Deficient.
