Abstract english

We present the methods for phenotype evaluation, which give good chances to identify taxa larger according to the anatomical and morphological features. The basic idea is to evaluate characters having regard to completeness and reproducibility. We composed a list of about 100 basic characters and propose standardized ways of measuring them. We also present a list of morphological and anatomical terms with their standardized meaning. Basic rules for collecting, preparing and measuring lichen material are described. The proposed phenotypic evaluation process has two levels: (1) a pilot study is carried out on a restricted number of samples, but all available characters are evaluated; (2) a detailed study of a large number of samples that includes only potentially diagnostic features that are chosen for the pilot study according to their discriminatory weight.
