The first fossil record of the anamorphic genus Zygosporium Mont. from the Oligocene of Csolnok (N Hungary)

Remains of a fungus with unique morphological characters were found on the leaf cuticle of a fossil leaf preserved in Oligocene deposits from Csolnok, Hungary. Vesicular conidiophores with characteristic, darkly pigmented, incurved vesicles were compared with those of the modern representatives of t...

Description
Summary:Remains of a fungus with unique morphological characters were found on the leaf cuticle of a fossil leaf preserved in Oligocene deposits from Csolnok, Hungary. Vesicular conidiophores with characteristic, darkly pigmented, incurved vesicles were compared with those of the modern representatives of the anamorphic genus Zygosporium . Based on the fossil find, a new fossil-species, Zygosporium oligocenicum G. Worobiec sp. nov., having vesicular conidiophores that arise directly from the mycelium, was described. The fossil Zygosporium oligocenicum presumably preferred warm climate and, similarly to most modern members of the genus, was a saprophyte on fallen, decaying leaves.
