Quantitative integrative taxonomy informs species delimitation in Teloschistaceae (lichenized Ascomycota): the genus Wetmoreana as a case study

The genus Wetmoreana was studied using quantitative integrative taxonomy methods to resolve the genus delimitation and explore its taxonomy diversity at the species level.

As a result, the genus Fulgogasparrea is synonymized with Wetmoreana , and the latter includes 15 formally described species, one subspecies, and three further, thus far undescribed species: W. appressa , W. awasthii comb.

nov., W. bahiensis sp. nov., W. brachyloba comb.

nov., W. brouardii , W. chapadensis comb.

nov., W. circumlobata sp. nov., W. decipioides , W. intensa comb.

nov., W. ochraceofulva comb.

nov., W. rubra sp. nov., W. sliwae sp. nov., W. sliwae ssp. subparviloba subsp. nov., W. subnitida comb.

nov., W. texana , and W. variegata sp. nov.

Eleven of 19 examined taxa are newly placed within this genus or confirmed to belong to it.

Two species, W. awasthii and W. intensa , are transferred to Wetmoreana without additional analysis but based on previous studies.

The W. brouardii and W. ochraceofulva species complexes are discussed in detail .

Additionally, Caloplaca muelleri and C. rubina var. evolutior are transferred to Squamulea , and the latter is elevated to the species rank.
