Number of days of sporocarp occurrences (Yes or No) out of the 28 survey days for (A) Amanita species; (B) Russula species. The output of occurrences is binary (1 or 0), e.g. in the case of Amanita mairei there were found fruitbodies 4 times out of the 28 survey days and there were not found any fruitodies 24 times out of the 28 survey days. The exact number of fruitbodies were not used for the calculations. The sample size (28 fungal data per ANN calculation) was appropriate for the ANN method (Haykin, 2009).
