Fig 2.
Phylogenetic tree of Plagiothecium taxa with Isopterygiopsis pulchella as the outgroup taxa based on concatenated nuclear (ITS1-5.8S-ITS2) and chloroplast (matK and rpl16) DNA markers (total 4127 bp).
The tree presents the position of Wolski morphotypes of Plagiothecium among the Plagiothecium group. Numbers on branches indicate posterior probabilities from BI analysis followed by bootstrap values from ML. Asterisk (*) indicates 1.00 (BI) and 100 (ML), while minus (-) indicates values below 0.9 (BI) and 90 (ML). The topology of the tree was based on ML analysis.
