Specimen notes
Public Note:
Thurs., May 8, 2003: Collection site at Waihi Beach. The point of land immediately to the North is characterized by a beautiful pohutukawa, macropiper and pouriri coastal forest. Collections were made from a dead but firm, decorticated pohutakawa trunk (part of an old log pile in a park a short walk from Waihi Beach).
Numerous ascomata of both the Tubeufia-like species (collection #870) and Tubeufia helicoma (collection #871) were present on the same log. The former was easily distinguished by its smaller, setose (rather than warted) ascomata and by its smaller, fewer-celled ascospores. The nature of its ascomatal setae, however, remains unclear. These were stout, simple, septate and dematiaceous. Their often lighter or hyaline, blunt apices frequently appeared to give rise to hyaline, septate extentions. Whether the latter were conidial fragments, perhaps of helicosporous conidia, is not clear. To be sure these setae (or conidiophores) are distinctly different than those of Helicosporium pannosum which were found among both types of ascomata (Tubeufia helicoma and the Tubeufia-like sp.) but never on the ascomata. Setae on ascomata of the Tubeufia-like sp. were much smaller than the H. pannosum setose conidiophores and never tapering at their apices. Asci 8-spored. Ascospores 45-60 µm long with (10-)11-12(-13) transverse septa.
