Melampsora laricis-populina Kleb. 1902

Type: Rust and Smut Fungi; Description: Spermagonia circular to lenticular, golden yellow, up to 0.5 mm in diameter, surrounded by a halo of yellow tissue; on needles. Aecia aggregated in groups of two to four, irregularly oval, yellow orange, 0.5–1.5 mm in diameter; on yellow spots on needles. Uredinia single or aggregated in groups, circular, bright orange yellow, 0.5–1 mm in diameter; on both sides of leaves. Urediniospores clavate to broadly ellipsoid, apex rounded, base truncate, 25–50 × 12–28 μm, uniformly echinulate except for a smooth area near the rounded apex. Telia occasionally single but more often aggregated in groups which coalesce, circular, amber brown to dark brown, up to 1 mm in diameter; on both sides of leaves. Teliospores cylindrical to triangular, 20–50 × 7–12 μm, pale.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough Sounds, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Mackenzie, Otago Lakes, Dunedin, Southland.; 1st Record: Anonymous (1973); van Kraayenoord et al. (1974).
Significance: This fungus was first detected in 1973 and spread rapidly, causing considerable damage in the moist areas of New Zealand. Infection leads to early defoliation, which, if repeated, reduces height and diameter growth and delays hardening-off. Shoots become more prone to frost damage and, in highly susceptible varieties (P. nigra ‘Sempervirens’, for example) there is dieback and death. Introduction of rust-resistant varieties has reduced adverse effects considerably. Natural infection of conifers is very rare. An interspecific hybrid between M. larici-populina and M. medusae has been described (Spiers & Hopcroft 1994).; Host(s): Spermagonia and aecia on Larix decidua, L. kaempferi, Pinus radiata. Uredinia and telia on Populus ×canadensis, P. deltoides, P. deltoides var. missouriensis, P. ×generosa, P. ×gileadensis, P. maximowiczii × berolinensis, P. maximowiczii × nigra, P. maximowiczii × trichocarpa, P. nigra, P. trichocarpa, P. yunnanensis.
