Pediastrum and Botryococcus are very well known objects in palynology. Beside them Coelastrum (UG-1233), Tetraedron (HdV-66, HdV-371) and Scenedesmus (HdV-770, UG-1239) occur in pollen slides. Different species of Pediastrum demonstrate different responses to environmental parameters such as turbidity, water chemistry, nutrient status, pH and geography, making Pediastrum a good indicator for recording changes in the trophic status of a lake (e.g. Nielsen and Sørensen 1992, Jankovská and Komárek 2000). Identification and palaeoecological interpretation of the fossil green algae can be done using overview works of Komarek and Marvan (1992), Jankovská and Komárek (2000) and Komárek and Jankovská (2001).

Cyanobacteria (formerly blue green algae) are photosynthetic prokaryotes able to produce oxygen and to fix nitrogen. They can be found in terrestrial and aquatic habitats and are known for causing blooms, which can be toxic. In fossil material, cyanobacteria, especially akinetes of Aphanizomenon (HdV-600) and Anabaena (HdV-601), showed phosphate-eutrophication of a Medieval lake as a consequence of intensification of farming and fertilization of the area around the lake (van Geel et al. 1994, 1996). There is no identification key for fossil Cyanobacteria and they can be identified with help of the descriptions in Ralska-Jasiewiczowa and van Geel (1992), van der Wiel (1982), van Geel et al. (1983b, 1994, 1996).

Desmidiales are the unicellular green algae of Conjugatophyceae. They inhabit mostly freshwater and may be found between Sphagnum mosses in peat bogs. Their cells are divided in two symmetrical parts separated by an isthmus. However, in the fossil stage they are represented by a half of the cell: Closterium idiosporum-type (HdV 60), Closterium cf. rostratum (HdV 372), Staurastrum (HdV 983). Together with other algal palynomorphs, desmids can be used as proxies of human impact on lacustrine ecosystem (McCarthy et al. 2018). Identification of the fossil remains to genus or species level is possible by using algological literature (Coesel and Meesters 2007, 2013 and Šťastný, 2010, 2013).

Cysts of dinoflagellates (dinocysts) are found mostly in marine sediments but also in freshwater. They represent resting stages in the life cycle of dinoflagellates that are microscopic unicellular algae belonging to the phylum Dinoflagellata. Two systems exist for identification of the dinoflagellates: (1) for biologists based on motile cells and (2) for palaeontologists based on resting stages. Since only 10-20% of dinoflagellate species produce cysts composed of highly resistant dinosporin, dinocyst assemblages provide only limited information about the former ecological community. Nevertheless, numerous studies on the distribution of dinocysts highlight their usefulness for reconstruction of salinity, temperature, ice-cover and productivity or eutrophication (de Vernal and Marret 2007, Marret and Zonneveld 2003, Zonneveld et al. 2013). There are several NPP types from dinocysts: Lingulodinium machaerophorum (HdV 704A), HdV 703A, HdV 703B, HdV 703C, HdV 704B, HdV 704C. Dinocyst studies belong to a special branch of palynology and several common identification keys for Quaternary dinocysts exist as papers or on-line resources (Rochon et al. 1999; Mudie et al. 2017; https://www.marum.de/Karin-Zonneveld/dinocystkey.html ).

Zygnemataceae are unbranched filamentous green algae of Conjugatophyceae, inhabiting shallow, stagnant, oxygen-rich freshwater lakes, ponds, small pools or wet soils. A few species inhabit salt water, but there are no marine representatives. During the sexual reproduction, Zygnemataceae produce thick-walled zygospores, which can fossilize and be found in the sediment archives. Apart from zygospores, asexual resting spores (aplanospores) can also be formed. The spores allow the algae to overcome unfavourable conditions such as drying of the sediment surface during summer or freezing during winter. In most cases the morphological characteristics of zygospores and aplanospores are necessary for identification to the species level. For information on extant Zygnemataceae, reference is made to Transeau (1951), Randhawa (1959), Kadlubowska (1984), and Hoshaw and McCourt (1988). Fossil spores recorded in pollen slides are: Mougeotia (HdV 61, HdV 133, HdV 134, HdV 135, HdV 136, HdV 141, HdV 313, HdV 373, HdV 711, HdV 772, HdV A, HdV B, t micro 418), Zygnema-type (HdV 213, HdV 314, t micro 419), Spirogyra (HdV 130, HdV 131, HdV 132, HdV 210, HdV 211, HdV 212, HdV 315, HdV 342, HdV 773, HdV D1, t micro 417, Tmic 19, UG 1240), Debarya (HdV 214). They have been described and their use as palaeoenvironmetal indicators was started by van Geel (1976). However, until now there is no formal identification key for spores of Zygnemataceae and the reference for fossil spores is made to a couple of papers with original descriptions and photographs of the types such as Ellis-Adam & van Geel (1978), van Geel and van der Hammen (1978), van Geel and Grenfell (1996), van Geel (1976, 1979, 2001), van Geel et al. (1989, 1994).

Helminth eggs are often found in sediments, indicating presence of parasitic worms, their host and the disease in the area. In palynological studies, especially very resistant eggs such as of Trichuris (HdV-531), Ascaris (Brinkkemper and van Haaster 2012), Capillaria (Shumilovskikh et al. 2016b), Dicrocoelium (Shumilovskikh et al. 2016a) occur. While harsh palynological laboratory treatments might change the morphology of the eggs, identification of resistant helminth eggs is still possible (e.g. Lardín and Pacheco 2015). Studies on helminths eggs from sediments and latrines has developed to a special field of palaeoparasitology, where gentle methods of sample preparation are used.

Testate amoebae are a group of eukaryotic microorganisms with a decay-resistant shell, which can get fossilized. While studies on testate amoebae are a subject of specialized analysis (Charman et al. 2000; Mitchell et al. 2008), the shells can be identified from pollen slides and used for reconstructions of hydrological changes, eutrophication or pollution (Grospietsch 1952; Mazei and Tsyganov 2006; Payne et al. 2012; Swindles and Roe 2007). Several NPP types were assigned to testate amoeba such as Amphitrema flavum (HdV-31A), A. wrightianum (HdV 31B, HdV 186, t 22), Assulina muscorum (HdV 32A) and A. seminulum (HdV-32B).

Fungal remains often occur in the pollen samples in form of thick-walled normally dark-coloured spores or dark-coloured hyphae. While hyphae cannot be identified morphologically, the variety of the fungal spores have distinct morphological characteristics. Fossil fungi are known since the Proterozoic (Taylor et al. 2015) and they are actively studied in geology (e.g. Elsik 1976, Graham 1962, Taylor and Osborn 1996). A special system has been developed for the description of fossil fungal remains (Elsik 1983) summarized by Kalgutkar and Jansonius (2000), presented in the on-line database of fossil fungi: https://advance.science.sfu.ca/fungi/fossils/Kalgutkar_and_Jansonius/. While working with deep-time geology it is difficult to establish the connection of fossil finds to the modern mycoflora, but this is possible to do with Quaternary material. Taxonomically the majority of fungal spores recorded in palaeoecological studies belong to Ascomycetes, Basidiomycetes and Hyphomycetes (van Geel 2001), in rare cases to Zygomycetes (e.g. zygospores of Mucor sp. described by Shumilovskikh et al. 2015a). However, for interpretation purposes they are usually grouped by their nutritional strategies rather than by taxonomy: (1) saprotrophs, general or specialized on dung (coprophilous fungi), wood (lignicolous fungi), charred material (carbonicolous fungi) or soil, (2) parasites such as rusts and smuts, and 3) mycorrhizal fungi (Webster and Weber 2007).
