Abstract
This review summarizes the present taxonomic knowledge of the polyphyletic family Pucciniosiraceae (Uredinales) and its genera. It shows that the genera are often imprecisely or arbitrarily delimited from each other. The situation is exemplified by the genus Cionothrix for which the presence of intercalary cells is reported for the first time.
The members of Pucciniosiraceae descended most likely from heteroecious species of the Puccinia-Uromyces complex (PUc) but the relationships are still largely unknown. Molecular analyses have not helped so far to remedy this situation because a reasonably complete phylogeny of the PUc to which the members of the Pucciniosiraceae could be linked is unavailable.
It is attempted, therefore, to relate members of Pucciniosiraceae with possible heteroecious progenitors by analysing host relationships, especially by the application of ‘Tranzschel’s rule’. The power and restrictions of this approach are discussed mainly by examples from the genus Endophyllum. It is concluded that the analysis of host relationships is an effective method to identify possible heteroecious relatives of endocyclic rust fungi. Molecular studies that include such wisely selected candidate species may produce more reliable phylogenies even if only a restricted number of species are analysed. Show more
