Descriptions
Phragmocephala stemphylioides (Corda) S. Hughes 1958
MID CANTERBURY: Christchurch Botanical Garden, dead twig of Quercus ilex, 9 Sep 2001, PDD 74769.
Conidiophores 110–120 × 7–10 µm at base, dark brown-black, paler towards apex, fasciculate (frequently in pairs). Conidiogenesis holoblastic, rhexolytic, producing secondary conidia. Primary conidia 4-septate, centre bands darker, base with frill, 25–30 × 11 µm, 4 µm wide at scar. Secondary conidia ellipsoid 13 × 10 µm.
New record from New Zealand. Phragmocephala stemphylioides and P. prolifera are similar species that may be distinguished by the dimensions of the primary and secondary conidia (Hughes 1979). In P. stemphylioides primary conidia are 22–30 × 11.5–14.5 µm, and secondary conidia ellipsoid 12.5–14.5 µm. In P. prolifera primary conidia are 29–36 × 16–20 µm, and secondary conidia subglobose 16–20 µm diam.
