3. ^ Threatened comprises CR, EN and VU. Upper estimate additionally includes DD.

As of December 2019^[update], the International Union for Conservation of Nature (IUCN) has evaluated the conservation status of 280 fungus species.^[1]

Previously in the 2017-3 release, the IUCN evaluated the conservation status of 56 fungus species.^[2] One subspecies, that of Pleurotus nebrodensis, also was evaluated but has since been removed. At the time no subpopulations were evaluated.

As of October 2002^[update], the New Zealand Threat Classification System listed 1512 species and 39 subspecies of fungi, with 65 species considered Threatened.^[3][4]
