[2] The genus name of Mairetis is in honour of René Maire (1878–1949), a French botanist and mycologist.

[3] The Latin specific epithet of microsperma means 'micro' meaning small and 'sperma' the Greek word for seed.

[4] Both the genus and species were first described and published in J. Arnold Arbor.
