Szaferomyces pliocenicus nov. gen., nov. sp. from the Upper Pliocene deposits of Mizerna (Poland), a fossil fungus showing close resemblance to modern powdery mildews
A fungal chasmothecium-like structure resembling those of the contemporary members of the Erysiphaceae was found during palynological investigations of Upper Pliocene deposits from Mizerna (borehole Mizerna-Nowa), southern Poland. This chasmothecium-like remain, preserved without any asci, ascospores and mycelium attached, is morphologically most similar to the chasmothecia of modern powdery mildews from the genera Erysiphe, Neoerysiphe, Podosphaera, and Salmonomyces. It differs from hitherto described fossil or modern fungi producing globose, closed ascomata with appendage-like setae. Therefore, a new fossil-genus and species name, Szaferomyces pliocenicus, is introduced for the fossil remains from Mizerna. Contrary to all previous putative fossils of powdery mildews, Szaferomyces pliocenicus nov. gen., nov. sp. is the most probable fossil of spore-producing organs of the Erysiphaceae found so far. However, due to the absence of some diagnostic morphological structures (other than presumptive chasmothecium) and DNA data, the affinity of this fungal fossil remains unclear.
期刊介绍：
Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils.
Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
