Abstract

Despite their importance in bio-deterioration, the taxonomy of the calcicolous endolithic genus Bagliettoa is still problematic, mostly because of difficult identifications and unsettled species concepts. In this study, the traditional morphology-based species and genus delimitations were tested using the phylogenetic markers ITS, mcm7 and mtSSU. Bayesian and Maximum Likelihood approaches were used on a dataset of 82 taxa to reconstruct phylogenetic relationships between the eight most common species of Bagliettoa. Molecular data confirmed the placement of B. limborioides, the generic type, within the clade including species usually considered as part of the genus Bagliettoa. Five other species were monophyletic and well supported (B. baldensis, B. calciseda, B. cazzae, B. marmorea and B. parmigerella). Relationships within a clade including B. parmigera, B. steineri and specimens with intermediate characters (here referred to as B. cf. suzaeana) are not resolved and weakly supported. This species complex (also called B. parmigera s.l.) is in need of a further revision. After revision of the type material, a lectotype is chosen for Bagliettoa parmigerella (Zahlbr.) Vězda & Poelt. Additionally, the new combinations Bagliettoa rubrocincta (Breuss) Gueidan & Cl. Roux and Bagliettoa suzaeana (Serv?t) Gueidan & Cl. Roux are proposed based on their morphological similarity to other species of Bagliettoa. A key to the 12 currently recognised species are provided, which will hopefully help ecologists and biogeologists to identify species from this difficult genus of endolithic lichens.
