Descriptions
Meria laricis Vuill. 1896
Both fungus and host species are introduced. Weston (1957) stated that the needle cast fungus Meria laricis is widespread in New Zealand on Larix decidua; he also noted that L. kaempferi (syn. L. leptolepis) was more resistant to the needle cast fungus than L.decirlua. It can be of considerable economic importance.
Meria laricis Vuill. 1896
Type: Foliicolous Fungi; Description: Mycelium internal, substomatal. Conidiophores emerging from stomata in dense tufts, simple or branched, frequently curved, hyaline, up to 45 μm long. Conidia cylindrical with a median constriction, 0-septate, 9–13 × 3–4 μm, smooth, hyaline. Leaf spots absent. The fungus is very difficult to see on the needles unless stained with aniline blue.
Distribution: Waikato, Bay of Plenty, Taupo, Rangitikei, Wellington, Hawkes Bay, Nelson, Westland, Marlborough, Kaikoura, North Canterbury, Mid Canterbury, South Canterbury, Dunedin, Southland.; 1st Record: Weston (1957).
Significance: The cause of premature needle cast in larch. Infected needles turn yellow, then red brown and are cast, usually in midsummer. Nursery seedlings and young plantations of Larix decidua are highly susceptible; L. kaempferi is regarded as relatively resistant. The disease is of minor significance.; Host(s): Larix decidua, L. kaempferi.
