MATERIAL EXAMINED: NEW ZEALAND, North Island, Kapiti Coast, north of Paraparaumu, Nikau Reserve, on decaying leaves of Freycinetia banksii, 1 May 1997, S.R. Whitton HKU(M)5063 (IFRD212-002). NOTES: Hydropisphaera erubescens is characterised by sessile, orange to orange-brown, globose ascomata and 55–84 × 9–15 µm asci. The ascospores are 17–29 × 3.5–5 µm, 3–4-septate, smooth, slightly constricted at the septa and hyaline (Samuels, 1978). Specimens HKU(M)5063, HKU(M)12800 and HKU(M)14049 are faintly ornamented and none of the collections have spores with constricted septa. These differences aside, ascomata morphology and ascospores size, septation and shape all agree with the description given by Samuels (1978) for H. erubescens. The faint ascospore ornamentation is thought to represent natural variation amongst specimens.
