A survey was conducted in Khartoum State to collect 150 samples of wild mushrooms from different areas. The identified specimens were Agaricus bernardii, Agaricus arvensis, Agaricus bisporus, Agaricus porphyrocephalus, Agaricus silvicola, Coprinus comatus and Lepiota cristata. Petroleum ether, ethanol and aqueous extracts of the mushrooms were screened for their antimicrobial activity against different pathogenic bacteria and fungi. These were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Aspergillus niger and Candida albicans using the cup plate agar diffusion method. All of the ethanol extracts were exhibited inhibitory effects against three or more of the tested organisms. The Minimum Inhibitory Concentrations (MICs) of the most active ethanolic extracts of the six mushrooms against standard bacteria were also determined. All of the mushroom extracts were phytochemically screened and carbohydrates, reduced sugar, flavonoids, alkaloids, saponins, sterols, coumarins and triterpenes were present in all of the mushroom samples.
