A mid-Cretaceous fungus, Philothysanus burmanicus gen. et sp. nov. (Ascomycota: Spheciophilaceae), on a thrip (Thysanoptera) in Burmese amber
Keyword(s):
Male and female thalli of a mid-Cretaceous fungus attached to a thrip (Thysanoptera) in Burmese amber are described as Philothysanus burmanicus gen. et sp. nov. in the family Spheciophilaceae (Ascomycota). Both spermatia and ascospores are present. Currently, Philothysanus burmanicus gen. et sp. nov., together with the previously described Spheciophilia adercia Poinar, represent the oldest known ectoparasitic fungi of insects and their age can be used as a reference point in future phylogenetic studies on the origin of fungi with this life style.
