MID CANTERBURY: Christchurch Botanical Garden, dead stems of Dicksonia squarrosa, 9 Oct 2001, PDD 74776, ICMP 14385

Conidiophores brown, septate, 130–250 × 5–6 µm at apex, arising from dark brown septate mycelium. Conidiogenesis enteroblastic, phialidic from a single locus. Collarette slightly flared, conidiophore proliferating. Conidia cylindrical with inconspicuous detachment scar, hyaline to pale yellow, 15–30 × 6–10 µm.

New record from New Zealand. This species has previously been recorded on Dicksonia antarctica in England by Kirk (1986) who noted the presence of a Trichosphaeria teleomorph. Dischloridium belongs to the Gongromeriza-Chloridium group described by Réblová (2000) and the associated chaetosphaeriaceous teleomorph should be looked for on New Zealand tree ferns. Dischloridium camelliae and its teleomorph Australiasca queenslandica were recently described from Camellia sinensis from Queensland, Australia (Sivanesan & Alcorn 2002). Both Matushima (1971) and Sutton (1976) described the conidiophores of D. laeënse as fasciculate, but this feature is not mentioned in Kirk (1981) or observed in the taxon reported here. D. regenerans is non-fasciculate but has larger conidia, 25–38 × 12–16 µm. Sivanesan & Alcorn (2002) stated that D. camelliae differs in having longer conidia and more robust conidiophores. Rong & Gams (2000) and Sivanesan & Alcorn (2002) provided keys and discussions of Dischloridium and related genera.
