Erdei, Boglárka; Lesiak, Maria: A study of dispersed cuticles, fossil seeds and cones from Sarmatian (Upper Miocene) deposits of Sopron-Piusz puszta (W Hungary)

Small amounts of plant debris after having been washed out were placed in ce. HF for a day or more ifit was required. Then fragments were treated due to poor preservation with HNO3 (cc. or sometimes diluted solution) instead of Schultze's solution and then with a 5% solution of KOH. Finally they were mounted in glycerine. By the morphological descriptions DlLCHER's (1974) and ELSlK's (1983) terminology was followed. SYSTEMATIC PART MYCOPHYTA (Ascomycetes) Trichothyriaceae Trichothyrites sp. (Fig. 5) 1978 Trichothyrites sp.; ELSIK, p. 336, Text-fig. 3. L. Material: BP 99.511.1. Description: The stroma attached to a dispersed cuticle is radially constructed with ostiolum in the centre. Its diameter is 180 urn. Hyphae and spores were not found. The cuticle is rather degraded. Because of the absence of stomata its closer affinities cannot be defined. Discussion: Fossil remains of the Trichothyrites genus represent a new taxon in our Sarmatian floras. Fossil remains of the genus are known from deposits ranging from Eocene to Pleistocene (ELSIK 1978). Trichothyrites fruiting bodies often occur on Buxus pliocenica Sap. et Mar. leaves coming from the Pliocene flora of Gerce (W Hungary). Most recent species of the family are tropical and parasitic on the stroma or mycelium of other microscopic epiphyllous fungi (BÁNHEGYI et al. 1985). GYMNOSPERMATOPHYTA Taxodiaceae Taxodiaceae gen. et sp. 1 Material: BP 99.496.1. Description: Cuticle is of medium thickness. Cells are isodiametric, only marginal cells seem to be a bit elongated. Length of cells is 43.7-87.5 urn, width is
