FIGURE 1 in Verrucaria hunsrueckensis (Verrucariaceae, lichenized Ascomycota), a new rare species with exceptionally slender ascospores from Germany

FIGURE 1. Phylogenetic placement of Verrucaria hunsrueckensis in comparison to other Verrucaria species with similarities in their morphological traits and type specimens of related species resulting from a RaxML-analysis under a GTRGAMMA model of the nuclear ribosomal ITS1-5.8S-ITS2 region. Support values are reported above or below the branches (bootstrap support [BT]/posterior probabilities [PP]). Sequences of Verrucaria nigrescens and V. macrostoma were used to root the tree.
