[ 1 ] - گزارشی از قارچ های ماکروسکوپی چوبزی غیر آگاریک در استان همدان (راسته‌های Hymenochaetales، Polyporales، Russulales)

اغلب قارچ‌های چوبزی باعث بیماری و ضعف درختان و درختچه‌ها گردیده و یا پوسیدگی درختان افتاده بر کف رویشگاه‌ها یا کنده‌های آن‌ها را سبب می‌شوند و همچنین به صورت همزیست موجب تقویت درختان می-گردند. بنابراین شناسایی و تفکیک مفید یا مضر بودن آن‌ها امری ضروری می‌باشد. با در نظر گرفتن وسعت جغرافیایی و تنوع اقلیمی غرب کشور، اطلاعات محدودتری در مورد تنوع تاکسونومیکی این گروه از قارچ‌ها در این مناطق، در مق...
