Plant material
Mushroom samples of boletus mushroom (Boletus edulis), champignon white (Agaricus bisporus), champignon brown (Agaricus bisporus var. Avellaneus), oyster mushroom (Pleurotus ostreatus), shiitake (Lentinula edodes) were collected in Bosnian market. Identification was done by comparing their morphological, anatomical and physiological characteristics and monographs with descriptions given in the manual (Moser, 1983; Bessette et al., 2000; Uzelac, 2009). The investigated mushrooms are five of the most commercially cultivated ones available in Bosnia.
