The Recently Extinct Fungi Database
The conservation status assigned to each entry should be taken as, to varying degrees, tentative. Cases where there is no suitable habitat left are rare, and they may still persist in captivity (knowingly or not). Thus an airtight case for extinction is very difficult to build. While most cases of rediscovery are due to a failure to have previously surveyed significant parts of known or suitable habitat. Or the organism was not, or at least should not, have been feared extinct in the first place. Decades without a record means absolutely nothing in and of itself. While the taxonomic validity or synonymy of a given taxon is somewhat subjective, and there is the very slight risk that a taxon will be (consciously or subconsciously) synonymised in order to reduce the number of extinctions.
Please use the Contact form to report any hyperlinks that no longer work ("deadlinks"). The internet is a dynamic place, and websites come and go all the time. As a single individual I cannot constantly check to make sure every single hyperlink still works, as there are 10,000's of them on the website.

Notes:
1 Taxonomic ranks encompassed by square brackets (i.e. "[" and "]") have no relevant subordinate taxa. That is, none of the species or subspecies included therein both a) survived at least until the late Pleistocene and b) are considered missing, extinct, rediscovered, or have been removed from these former categories due to taxonomic invalidity. This juxtaposition of non-empty and empty taxonomic units helps to identify potential instances of taxonomic bias in recent extinctions, and by extension those groups of organisms that may have an innate buffer against extinction.
