Megjegyzések:Fungal species identities are often based on morphological features, but current molecular phylogenetic and other approaches almost always lead to the discovery of multiple species in single morpho-species. According to the morphological species concept, the ant-parasitic fungus Rickia wasmannii (Ascomycota, Laboulbeniales) is a single species with pan-European distribution and a wide host range. Since its description, it has been reported from ten species of Myrmica (Hymenoptera, Formicidae), of which two belong to the rubra-group and the other eight to the phylogenetically distinct scabrinodis-group. We found evidence for R. wasmannii being a single phylogenetic species using sequence data from two loci. Apparently, the original morphological description (dating back to 1899) represents a single phylogenetic species. Furthermore, the biology and host-parasite interactions of R. wasmannii are not likely to be affected by genetic divergence among different populations of the fungus, implying comparability among studies conducted on members of different ant populations. We found no differences in total thallus number on workers between Myrmica species, but we did observe differences in the pattern of thallus distribution over the body. The locus of infection is the frontal side of the head in Myrmica rubra and M. sabuleti whereas in M. scabrinodis the locus of infection differs between worker ants from Hungary (gaster tergites) and the Netherlands (frontal head). Possible explanations for these observations are differences among host species and among populations of the same species in (i) how ant workers come into contact with the fungus, (ii) grooming efficacy, and (iii) cuticle surface characteristics.

Cím:Studies of Laboulbeniales on Myrmica ants (III): myrmecophilous arthropods as alternative hosts of Rickia wasmannii / Walter P. Pfliegler, Ferenc Báthori, Danny Haelewaters, András Tartally
Megjegyzések:Myrmecophilous arthropods and their manifold relations to host ants are interesting from an evolutionaryperspective. Rickia wasmannii is an ectoparasitic fungus belonging to the Laboulbeniales order. Here, we show thatinquiline mites can become infected by R. wasmannii, which was thought to be restricted to the genus Myrmica(Hymenoptera: Formicidae). This is the first report of R. wasmannii from an alternative host in another subphylum(Chelicerata). We also found immature fruiting bodies on a larva of Microdon myrmicae (Diptera: Syrphidae), whichrepresents the first report of any Rickia species on flies. This fungus is capable of infecting alternative, unrelated hostspecies as they co-occur in the ant nest "microhabitat". These observations provide direct evidence for ecologicalspecificity in Laboulbeniales. The presence of R. wasmannii on inquilines in Myrmica ant nests suggests that theparasite may have adapted to the ant nest environment and is less dependent on acquiring specific nutrients fromthe hosts. However, the alternative cannot be excluded; these infections might also represent chance events if thefungus is incapable of fulfilling its life cycle.
