Fungal collection inspectors do not have microscopical skills or medical knowledge, so that emergency experts, with the help of microscopy, and especially spore analysis, are needed to determine which of the 18 poisoning-syndromes conforms to initial symptoms and latency period The purpose of this course is to further interdisciplinary co-operation between medicine and mycology, and to demonstrate possibilities and limitations of mycological emergency diagnoses. Often one must be satisfied by only circumstantial evidence, even when knowledgeable mycologists are involved.
