Descriptions
Marssonina castagnei (Desm. & Mont.) Magnus 1906
Type: Foliicolous Fungi; Description: Conidiomata acervular, scattered, intraepidermal, up to 400 m in diameter; on roughly circular to irregular, chestnut brown leaf spots up to 5 mm wide with whitish centres on upper surfaces of leaves, spots often becoming confluent and covering large areas of the leaf. Conidia obovoid to pyriform, straight or slightly curved, unequally 1-septate, 15–18 × 5–8 μm, smooth, hyaline. Microconidia ellipsoid, 0-septate, 3–6 × 2 μm, hyaline.
Distribution: Auckland, Bay of Plenty, Taranaki, Taupo, Gisborne, Rangitikei, Wellington, Wanganui, Hawkes Bay, Wairarapa, Nelson, North Canterbury, Otago Lakes, Southland.; 1st Record: Anonymous (1986).
Significance: The widely-used Populus alba ‘Silver Poplar’ is particularly susceptible to attack and many trees of this cultivar have been killed since the fungus was introduced into New Zealand sometime between 1984 and 1986 (Spiers 1998). Most other cultivars of P. alba are resistant.; Host(s): Populus alba.
