specimen are deoperculate. A mean value of d was then computed for each species separately and the difference in mean was tested for statistical significance using Student's t-test. Nomenclature of mosses follows CORLEY et al

. ( 1981 ) and CORLEY and CRUNDWELL ( 1991 ), that of liverworts GROLLE and LONG (2000). RESULTS Of the 98 specimens obtained from BP one did not represent a species of the Funaria muhlenbergii group. Of the remaining 97 specimens, 45 (37 after correction for duplicates) were F. muhlenbergii and 52 (39) F. pulchella. 70 out of these 97 specimens (72.2%) were collected by Boros, the outstanding personality in Hungarian bryology of the 20th century. A list of the specimens studied, together with the results of the revision, is given in Appendix 1. It was in all cases possible to name species unambiguously; no intermediates were encountered. The following morphological characters proved to be the most useful with the Hungarian material (Table 1, Fig. 1): (i) the denticulation of the leaf margin in the upper part of the leaf (Fig. 1 A, D); (ii) the size and shape of the ripe theca (Fig. IB, E); (iii) the ornamentation of the spore surface (Fig. IC, F). Table 1. Morphological characters useful in distinguishing between F. muhlenbergii and F. pulchella (CRUNDWELL and NYHOLM 1974, LlMPRICHT 1859 and own observations). Funaria muhlenbergii Funaria pulchella Leaf margin sharply serrate in upper half nearly entire to bluntly of leaf by projecting cells; denticulate by slightly promarginal cells usually longer jecting cell ends; and narrower than adjacent marginal cells similar to adcells jacent cells Spore surface coarsely papillose finely papillose to vermiculate Size and shape of ripe theca ca 3 mm, oblong-pyriform ca 2 mm, subglobular-pyriform Stomatal number (mean + s.e.) 71.2+2.9 30.0±1.5 Length of terminal cell of leaf up to 450 urn up to 280 urn, but often apex shorter Length of seta 7-11 mm 5-8 mm
