The most frequent parasitic and saprophytic fungi on black alder (Alnus glutinosa Gaertn.) and grey alder (Alnus incana Mnch.) trees

Abstract

The parasitic and saprophytic mycoflora occurring on black alder and grey alder trees was studied. On black alder 28 species of fungi were identified, of which: on the leaves 3 species, on the bark of dead branches 3 species, on wood (wood rotting fungi) 20 species, and 2 species on the ground. On gray alder 21 species of fungi were identified, of which: on the leaves 3 species, on male flowers 1 species, on female fl owers 1 species, on the bark of dead branches 4 species, and on wood 12 fungi. Some fungi occur on both host plants, and among them the most frequent and the most significant are: Armillaria mellea, Fomes fomentarius, Fomitopsis pinicola, Inonotus radiatus and Laetiporus sulphureus.
