DESCRIPTION: This species is parasitic on Erythroglossum laciniatum (Lightfoot) Maggs & Hommersand (1993) . The protologue description can be found in Feldmann & Feldmann (1951) . BASIONYM: Asterocolax erythroglossi Feldmann & Feldmann (1951) Comptes rendus des séances de l’Académie des Sciences t. 233, p. 1139. TYPE LOCALITY : Brest, France (coll. J .Feldmann & G . Feldmann, 1951 , Feldmann 8008) NEOTYPE : Astan, baie de Roscoff , France (coll. Maggs & Hommersand, 1993 , Feldmann 9204) ETYMOLOGY: The specific epithet refers to the organism’s host and uses “-cola” (dweller or inhabitant, always treated as feminine despite gender of genus [ Stearn 1992 ]) to maintain recognition of the parasitic nature of the organism. REFERENCES: Feldmann & Feldmann 1951 , 1958 ; Maggs & Hommersand 1993 ; Goff et al. 1997 DNA SEQUENCES: GenBank accession number U59789 , Goff et al. 1997 , Wales , United Kingdom REMARKS: The original type species of Asterocolax was collected on Erythroglossum sandrianum (Kütz.) Kylin from ‘rade de Brest’, France , but the herbarium material is missing. A neotype was collected by Maggs and Hommersand (1993) on Erythroglossum laciniatum in Astan, baie de Roscoff, France . The specific epithet for Asterocolax erythroglossi was changed in order to prevent the creation of a tautonym ( Turland et al. 2018 , Article 23.4).
