The fruiting bodies of Rhizopogon rubescens grow semi‐buried in sandy soil under Pinus pinea in the western mountain ranges of Lebanon. The immature fruiting bodies of this fungus were collected in autumn and early winter. The collected material was cut into 1 mm‐thick slices, dried in the shade at room temperature and extracted with 95% ethanol for 2 days in a Soxhlet apparatus. The alcoholic solution was evaporated under vacuum. Disks were prepared to contain 4, 8 and 16 mg of R. rubescens extract. Antimicrobial testing was performed using the Disk Diffusion method using blood Muller‐Hinton agar media against the following organisms (obtained from ATCC): Staphylococcus aureus , Streptococcus Gp A, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa and Candida albicans. Streptococcus Gp A . The R. rubescens extract was found to be effective against Staphylococcus aureus and Streptococcus Gp A and caused at MIC of 16 mg/disk, the following growth inhibition zones; Staphylococcus aureus 10 mm, Streptococcus Gp A 12mm. No growth inhibition was noticed with the following spp. E. coli, P. vulgaris, P. aeruginosa , and C. albicans . Our results indicate a potential antimicrobial activity of R. rubescens ; however, further work is needed to identify the active agent.
