Specimen notes
Public Note:
Apothecia forming within the leaf tomentum on the undersides of living leaves of alpine Asteraceae. Apothecia very small, sessile, cupulate to globose, margin rolled in across the top of the hymenium. Wall mostly pale, darker around edge of cup, where the excipular elements are thickly encrusted with dark brown material. Cells of excipulum thick-walled, wall hyaline, becoming long-cylindric and somewhat free towards the edge of the cup, otherwise short and broad cylindric. Asci broad-cylindric to subfusoid, tapering to small, slightly thickened, J+ apex. Paraphyses undifferentiated at apex.
Based on ascospore morphology there are at least four macromorphologically similar species in New Zealand:
PDD 119633 - ascospores narrow-cylindric, 10-12 x 1.5 µm
PRJ D210 - ascospores broad-elliptic, 1-septate, 15 x 5 µm
PDD 48934, PRJ D234 - ascospores short-cylindric, 3-septate, 12-18 x 3-3.5 µm
PRJ D222, PRJ D226, PRJ D236 - ascospores acicular, 3-6 septate, 30-50 x 1.5 µm
Based on an ITS sequence from dried specimen of PDD 119633, these fungi have an isolated position within Helotiales.
