Tatraea dumbirensis or T. macrospora
Zuidland Peter,

I find these on the underside of wet wood in areas of Eucalyptus and Acacia and I am having trouble deciding what it might be (I am an amatuer). I am unsure if the spores might be considered to have pointed ends as per T.macrospora, they aren't curved as T.dumbirensis; the length is slightly longer than in other submissions in the forum but in the forum there is some variation.
Asci 150 x 10
Spores: (21-)22 - 29(-31) x 7-9; Q=3.4
Many thanks
Peter

Re : Tatraea dumbirensis or T. macrospora
Hi
this could indeed be T. macrospora and its synonym Ombrophila decolorans, but there are also various collections of straight-spored Tatraea aff. dumbirensis which require clarifiyation by DNA study. Phaeohelotium lilacinum is another such candidate which requires clarification.
Is this possibly the first record for Australia? Who knows if there exist old unclarified decriptions such as those of discomycetes by Rodway?

Re : Tatraea dumbirensis or T. macrospora
Thank you for your response Zotto.
It would be a first recording for T.dumbirensis and the first for T.macrospora with microscopy; there are 3 sightings with images for T. macrospora but their apothecia look different (colour and shape) and no microscopy is provided. I can find no records for the other species you mention.
The spores of T.macrospora in Spooner (1987) look different to my findings but he did that work with a preserved specimen.
I thank you for your insight and time in looking at this.

Re : Tatraea dumbirensis or T. macrospora
I suppose this genus can only be solved with combined morpho-DNA studies, as so often, and it would be helpful to gain a sequence from your sample. Luis Quijada is probably interested. He started a study 6 years ago.
