The natural environment of Prague Castle and its surroundings in the Early Middle Ages: Evidence provided by a pollen analysis of sediments from the Third courtyard.
Fungi (Ascomycota, Basidiomycota) form crystals of various inorganic and organic compounds on their mycelium and fruitbodies. Crystals are formed either when fungal metabolites released into the surrounding environment react with compounds already present and then crystallise, or when the metabolites produced in sufficient quantities crystallise directly at optimal conditions. Both examples were observed in nature and also under labora - tory conditions and show a wide spectra of metabolites produced by fungi. and Ondřej Koukol.
