“…The Kongor core was obtained from the temporary lake Kongor, located in the Artemisia-steppe of the eastern Gorgan Plain, NE Iran. Samples from the core were treated with standard palynological laboratory procedures and studied for pollen and non-pollen palynomorphs including microscopic plant, animal and fungal remains (details in Shumilovskikh et al, 2016). For the purpose of this paper we present an abbreviated version of the palynological diagram with freshwater fungi, arboreal pollen and tree and shrub macroremains (Fig.…”

“…Interestingly, the continuous presence of woody vegetation on the Kongor site is neither indicated by pollen nor by macroremains (Fig. 1), but by insects, strongly suggesting the presence of riverine forests with Alnus or Salix close to the site (Shumilovskikh et al, 2016). In fact, pollen of woody vegetation is present in the pollen diagram (4-20%), but due to possible long-distance transport it is not possible to infer local vegetation (Fig.…”

“…During palynological investigations of a sediment core from Kongor (NE Iran), covering the last 6000 years (Shumilovskikh et al, 2016), fungal spores of Megalohypha aqua-dulces Ferrer et Shearer were documented (Plate I) and identified using mycological literature (Ferrer et al, 2007). These spores share similar characteristics to additional fossilised spores from geological records described as Fusiformisporites Rouse, 1962.…”

The first Holocene record of the freshwater ascomycete Megalohypha aqua-dulces from the sediment core Kongor (NE Iran) is presented here. Based on the similarity of the spore morphology with the fossil form genus Fusiformisporites, we establish a link between extant and fossil taxa. Comparative analysis of morphological characteristics of fossil spores of Fusiformisporites indicates that several different fungal groups might be included in this form genus. At least five species of Fusiformisporites share similar morphology with spores of Megalohypha aqua-dulces: Fusiformisporites annafrancescae, Fusiformisporites crabbii, Fusiformisporites keralensis, Fusiformisporites paucistriatus, and Fusiformisporites pseudocrabbii. Based on Fusiformisporites, the evolution of Megalohypha aqua-dulces can be traced to the late Cretaceous, corresponding with diversification of the flowering plants and pointing to a co-evolution of both groups. Megalohypha aqua-dulces has a tropical to subtropical distribution but also occurs in the semi-arid steppe environments of Kongor together with other freshwater fungal genera such as Xylomyces, Dictyosporium, and Sporoschisma, which spores we describe here. The ecological requirements of Megalohypha indicate that its spores can be used for the palaeoecological sign of dead submerged wood as well as of tropical to subtropical conditions.

Palynological and geochemical analyses provide valuable information about modern and past climatic regimes and vegetation. The impact of climate and humans on past vegetation in the semi‐arid areas of northwestern Iran has received increased interest in the wake of warming temperatures in the Middle East. Palynological and down‐core XRF elemental abundances from a peat core from Lake Neor enabled a reconstruction of vegetational changes of the past 7000 years over the highlands of northwestern Iran. Periods of increased arboreal pollen (AP) types and high (Artemisia + Poaceae)/Chenopodiaceae ratios along with low titanium abundances, high percentages of total organic carbon, more negative δD values, and higher carbon accumulation rates suggest a relatively wet climate. These conditions have persisted during the periods 6700–6200, 5200–4450 and 3200–2200 cal a bp. The overall low AP values, substantial rise of Chenopodiaceae, high Ti abundances and low values of palaeo‐redox proxies, are all evidences of a drier climate, as has been reconstructed for the periods 6200–5200 and 4030–3150 cal a bp and the last 2200 years. An important feature of the last centuries is the increase of anthropogenic and pastoral indicator pollen types. Our results may provide basic data to predict future trends in vegetation dynamics under future climate change in western Asia.
