The first enumeration of members of the Teloschistaceae status of which hitherto confirmed
by three gene phylogeny based on nrITS, nrLSU and mtSSU sequences is provided. The
enumeration includes also taxa for which minimum two nuclear (nrITS or/and nrLSU)
and mitochondrial DNA sequences hitherto available with references to publications
where they are published. The enumeration including 590 species is alphabetically
arranged after 115 accepted generic names within five subfamilies, i.e.: Xanthorioideae
(271 species), Caloplacoideae (217 species), Teloschistoideae (69 species), Brownlielloideae
(23 species), and Ikaerioideae (10 species). Accepted names are provided in bold and
in italics, while synonymous names previously included in the genera Caloplaca, Xanthoria
or Teloschistes as well as some taxa of the genera Polycauliona, Gyalolechia, Dufourea
are provided in italics only. Recently described or combined taxa within genera segregated
aft er molecular phylogeny data are briefly discussed. Six new combinations are proposed
for the following taxa: Huriella osseophila (for Squamulea osseophila Søchting et
Bungartz), Huriella phyllidizans (for Caloplaca phyllidizans Wetmore), Loekoeslaszloa
catillarioides (for Caloplaca catillarioides Arup et van den Boom), Pyrenodesmia areolata
(for Caloplaca cerina var. areolata Zahlbr.), Pyrenodesmia emilii (for Caloplaca emilii
Vondrák, Khodos., Cl. Roux et V. Wirth), Pyrenodesmia fuscoatroides (for Caloplaca
fuscoatroides J. Steiner). Position of taxa hitherto identified only on the basis
of ITS phylogeny, or on incomplete set of gene sequences are briefly discussed too.
