Abstract
Some fruiting body fungi, such as mushrooms, have valuable nutritional and medicinal properties. The present study aimed to report some mushroom species for the first time in several regions of Saudi Arabia: Abha, Al-Baha, Al-Taif, and Jeddah. Morphological and microscopic features, the internal transcribed spacer (ITS) region, and a Basic Local Alignment Search Tool (BLAST) analysis were studied to identify Crinipellis scabella, Parasola conopilea, Agrocybe pediades, Pyrofomes demidoffii, and Tulostoma fimbriatum in Al-Baha, and Conocybe macrospora, and Chlorophyllum palaeotropicum throughout Saudi Arabia. All mushrooms identified in this present work were Agaricomycotina mushrooms recorded for the first time in Saudi Arabia.
