Over 4,000 species of fungi have been recorded from Slovakia. Of these, nearly 1,500 are lichen-forming species. Some of these fungi are undoubtedly endemic, but not enough is known to say how many. Of the lichen-forming species, about 40% have been classified as threatened in some way. About 7% are apparently extinct, 9% endangered, 17% vulnerable, and 7% rare. The conservation status of non-lichen-forming fungi in Slovakia is not well documented, but there is a red list for its larger fungi.
