Molecular data confirm the presence of Anacolia menziesii (Bartramiaceae, Musci) in Southern Europe and its separation from Anacolia webbii
ISSR (Inter-Simple Sequence Repeat) fingerprint data and nrITS sequences confirm the presence of Anacolia menziesii in Europe. The species is more variable genetically in North America than in Europe. The data show only minor differentiation between the North American and European populations of A. menziesii. Anacolia webbii is morphologically and genetically very similar to Anacolia menziesii, but can be separated from Anacolia menziesii with high confidence based on the ITS and ISSR data. Long distance dispersal is the most likely explanation for the disjunction of Anacolia menziesii between North America and Europe.
