Megalospora gompholoma ssp. gompholoma is the most widely collected species of the genus in New Zealand. It is known from a wide variety of bark substrata: Dacrydium cupressinum, Griselinia littoralis, Hoheria populnea, Melicytus ramiflorus, Metrosideros spp., Myrsine australis and Nothofagus menziesii. It is characterised by: the presence of pannarin; atrorubicans -type ascospores (1-septate, 1 per ascus, 80–165 × 25–43 μm); dull, not glossy apothecial disc and with pruina developed in young fruits, characters which distinguish it from both M. atrorubicans ssp. australis and M. campylospora.
