Specimen notes
Public Note:
Peziza autrogeaster was described by Rifai from Tasmania with spores 23.6-27.3 x 14-16.3 and with apicular adherent material staining in cotton blue. P. ammophilla has spores 14-16x10 [14-21 x 10-12 in some texts] and spores without apicular material. Other collections of P. ammophila from NZ have spores around 19 x 11 and with or without apicular elements thus questionably either species. Certainly NZ material has sequences different to European material but, morphologically, do not fit P. austrogeaster. In this material the spores are smooth, without apicular material and length=17.1–19.9µm (µ=18.5, σ=0.66), width=9.0–11.3µm (µ=10.0, σ=0.59), Q=1.7–2.0µm (µ=1.85, σ=0.09), n=20. The material is not P. austrogeaster in the sense of Rifai's description and the spores fall within the range of other NZ P. ammophilla aff. collections. Rifai's observations require checking because it is still possible P. austrogaster provides the correct name for this taxon if it can be shown he overestimated spore size and apicular material inconsistently present. The packet has an annotation slip from Peter Johnston referring to PDD23558.

Public Note:
In addition to P. oceanica current sequence data indicate an additional species for which the name P. austrogeaster may be appropriate, albeit with spores that are smaller than Rifai's description. The species is co-present with P. oceanica in Canterbury, and is possibly distinguished by a pronounced gastroid habitat and narrow apothecial opening.
