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.

Short notes: First report of the lignivorous fungus Paecilomyces maximus in Cedrus atlantica M. In Morocco

This study is interested in isolating fungi from the wood parts of cedar trunks withered and identifying these lignivorous fungi. A sample was isolated from the cedar grove of Tazekka National Park located south of the city of Taza in Morocco. The culture and purification of the isolated fungus were done on a water agar medium and then on a PDA medium. After the purification of the fungus, a morphological study by scanning electron microscope allowed us to identify the pathogen Paecilomyces. A molecular characterization identified Paecilomyces maximus with a coverage percentage of 99% and an identity of 98.77%. To our knowledge, this is the first report of P. maximus in decayed cedar wood.
