A description is provided for Mycogone rosea . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cultivated mushrooms, Amanita rubescens, A. caesaraea, Inocybe sp., Trichloma terreum , termite fungus garden. DISEASE: A disease of mushroom similar to 'wet bubble' in some respects. Causes dark brown discoloration of caps with underlying tissues stained yellow.
