Thanks … I have also tested antimicrobial activity of a big number of fleshy fungi and found good antifungal as well as antibacterial activity. Specially I wanted to use these fleshy fungi as the substitute of fungicides. I performed some trials against Phytophthora nicotiana var parasitica a pathogen of leaf rot and foot rot diseases of Piper betle but could not get satisfactory results.
