A list of myxozoan genera is presented in the current taxonomical scheme. These genera are defined; their type species and most important pathogens along with their hosts are listed. Simultaneously, definitions of actinospore stages representing sexual stages of the myxosporean life cycle are given; altogether, 17 actinospore collective groups with 180 types have been described. Life cycles of the two classes of the phylum Myxozoa, Malacosporea and Myxosporea, are briefly outlined with specification of the appropriate terms. Up to now, 4 malacosporean and 2,180 myxosporean species assigned to a total of 62 genera, have been established. The surviving classification of myxosporeans, based on spore morphology, is discussed in the context of the still fragmentary data resulting from SSU rDNA sequence analyses. The main task for the future is a rigorous, detailed morphological description combined with molecular techniques in establishment of new species and in revision of the existing ones. Establishment of a classification acceptable from morphological, biological and phylogenetical viewpoints is necessary.
The paper studies the typology of the initials following the way of construction of their corpus in the mutual ties in the development – departing from the late antique, considering the Byzantine and Pre-Romanesque and Romanesque types. The modifications of the initials are studied together with the changes of their function in the decoration system and in the cultural-historical context. The contribution also studies the changes of the terminology connected with the typology of the initials.
The paper is engaged with a definition of the typolotgy and modifications fo the caligraphic initials, compared with the typology of painted initials, and also with a comparative study of the terminoloty used in different languages for the specific compositions. The interest is also focused on relations among countries, regions and workshops that participated in the transformations of the caligrafic initials. The subject is studied on a broad period, from the Late Antiquity till the 16th century, but without a typology of fleuronée, only compositions of the body of the initials have been taken into consideration.
