Contributions on the ecology of the Central European Leucobryum taxa and their determination

We characterise Leucobryum juniperoideum regarding its morphology and ecology based on own collections and data from the literature. We classify features to separate it from other Leucobryum taxa used in common identification keys according to their actual suitability to distinguish these taxa. Sporophytes, lamina, hyalocytes, and colour of the cushions provide helpful features for determination. A discussion of the favoured substrates of L. juniperoideum is given. We compare Leucobryum glaucum, including two small-leaved forms with L. juniperoideum and L. albidum, and provide identification keys.
