Short notes: First Report of the Phytopathogenic Fungus Alternaria tenuissima in cedarwood (Cedrus atlantica M.) in Morocco

Our research focuses on identifying lignivorous fungus from decayed cedarwood. A sample was taken from Azrou forest’s cedar grove, which is a part of Morocco’s Ifrane National Park. On a water agar medium first, and subsequently a PDA medium, the isolated fungus was cultured and purified. After the fungus was purified, an optical microscope morphological analysis allowed us to identify the pathogen Alternaria tenuissima. These findings were confirmed by a molecular characterisation, which had a coverage rate of 94% and an identity of 94,88%. This is the first report of A. tenuissima in decomposing cedarwood that we are knowledge of.
