Allantophomopsiella pseudotsugae (M. Wilson) Crous 2014

Notes: Distinct from Apostrasseria and Allantophomopsis in that it lacks percurrent proliferation on its conidiogenous cells, and has inequilaterally fusiform or naviculate conidia.
Both fungus and host plants are introduced; Birch (1935) stated that this fungus attacked stems of wounded trees one to ten years old, particularly after late frost injury. He noted that it destroyed many thousands of acres of Pinus radiata planted in unfavourable sites in 1925-35. Gilmour (1966a) noted that it is still common and widespread in its occurence in New Zealand pine forests.
Type: Caulicolous Fungi; Description: Conidiomata stromatic, pycnidial, scattered to gregarious, at first immersed, later erumpent, dark brown to black, 0.1–0.7 mm in diameter, ostiolate; on cankers on young shoots and on needles. Conidia ellipsoid, 0-septate, 5–7 × 2–4 μm, smooth, hyaline, with an irregular mucoid appendage at the apex.
Distribution: Bay of Plenty, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough Sounds, Marlborough, North Canterbury, Mid Canterbury, Dunedin, Southland.; 1st Record: Birch (1935: as Phomopsis strobi).
Significance: Although it is not a primary parasite, this fungus aggravates damage caused by frost. The resulting dieback of branches and terminal shoots often leads to malformation but rarely causes mortality, except in young seedlings. Between 1925 and 1935 the fungus caused considerable damage to young (1–10 years old) Pinus radiata plantations on frost flats at altitudes of 600 m and above in central North Island (Birch 1935). Changes in silvicultural practices have reduced the incidence of frost damage and the fungus is now only of minor importance. It is occasionally reported from sites subject to heavy frosts in late spring, particularly those where windrowing has been carried out or hardening-off of nursery stock has been neglected.; Host(s): Pinus canariensis, P. muricata, P. radiata, Pseudotsuga menziesii.
