Sclerophoma pithyophila (Corda) Höhn. 1909

Description

Type: Caulicolous Fungi; Description: Conidiomata pycnidial, scattered or gregarious, immersed, becoming erumpent, globose to irregular, black, 0.1–0.3 mm in diameter; on young shoots and less commonly on needles. Conidia ovate, 0-septate, 4–8 × 2–3 μm, smooth, hyaline. In culture, this fungus produces a Hormonema state (Hormonema dematioides Lagerberg & Melin) which is a smooth, black colony covered with a whitish slimy mass of conidia. The appearance is very similar to that of colonies of Aureobasidium pullulans (de Bary) G.Arnaud.

Distribution

Distribution: Northland, Auckland, Coromandel, Bay of Plenty, Rangitikei, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Westland, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Mackenzie, Central Otago, Dunedin, Southland.; 1st Record: Gadgil (1971).

Notes

Pathogenicity

Significance: Although it is not a primary pathogen, this fungus colonises tissues killed by frost and then invades healthy tissues, causing dieback, cankers, and needle blight (Gadgil 1971). It can be a problem after unseasonable frosts.; Host(s): Pinus contorta, P. radiata.
