Melampsora epitea Thüm. 1879

Description

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 solitary or confluent in groups of two to four, subcuticular, orange yellow to pale yellow, 0.4–1.5 mm in diameter. Uredinia erumpent, globose to oval, orange yellow, 0.5 mm in diameter; on the lower surfaces of leaves. Urediniospores globose to ellipsoid, 12–19 × 10–16 μm, uniformly echinulate. Telia subepidermal, chestnut brown to light brown, 0.1–0.7 mm in diameter, often confluent; mainly on the lower surfaces of leaves. Teliospores rectangular to triangular, 16–40 × 7–16 μm, brown.

Distribution

Distribution: Auckland, Coromandel, Waikato, Bay of Plenty, Taupo, Rangitikei, Wanganui, Hawkes Bay, Wairarapa, Nelson, Mid Canterbury, Dunedin.; 1st Record: Dingley (1977).

Notes

Pathogenicity

Significance: Leaf rusts caused by this and other Melampsora species cause premature defoliation in willows and are regarded as important diseases limiting growth of susceptible cultivars. Species cannot be distinguished by gross morpho-logical characters in the field. Natural infection of conifers not known.; Host(s): Spermagonia and aecia on Larix decidua, L. kaempferi. Uredinia and telia on Salix aegyptiaca, S. aurita, S. ×calodendron, S. caprea, S. cinerea, S. ×dichroa, S. ×mollissima, S. ×mollissima var. hippophaeifolia, S. muscina, S. pontederana × gracilistyla, S. purpurea, S. ×reichardtii, S. ×rubra, S. ×sericans, S. ×seringeana, S. silesiaca.
