The genetic diversity of the only known population of Pohlia bolanderi (Lesq.) Broth. in Europe was studied by ISSR molecular markers. A few samples of a putative P. andalusica (Höhn.) Broth., growing mixed with P. bolanderi in one of the studied patches, were included in the analysis. The results show that P. andalusica is clearly distinct from P. bolanderi. The inter-species values for pairwise genetic distance obtained by using the Jaccard index are in the range 0.72-0.79. The intra-species values found using the same index are between 0.03 and 0.38 in the case of P. andalusica and between 0.00 (genetically identical) and 0.47 in the case of P. bolanderi. This range points to the high genetic diversity of P. bolanderi, which is considered as a rare species. According to IUCN criteria, the available data suggest that P. bolanderi, which is mainly threatened by air pollution and tourist development, should be accepted as a vulnerable species in Europe.
