摘要:Geastrum hirsutum was described in 2006 and synonymized with G. trichiferum in 2012 . Reevaluating the nomenclature and the typification of the two Geastrum species, it was found that G. trichiferum cannot be used since its basionym Geaster trichifer is a nomen nudum as it was published without description or reference to a previous effectively published description. Attempting to validate the name G. trichifer , a lectotypification was made in 2012, which does not resolve G. trichifer ’s situation, since G. hirsutum has publication date priority over the lectotypification. As a nomen nudum , Geastrum trichiferum becomes unavailable and can no longer be used, since it was not validly published
