With that mulberry look - another possibility is a species of Bertia. I've seen the genus once , a collection sent from coastal northern NSW.

Thanks Heino, it appears regularly but its one I usually ignore, and I've not heard of 'Wood Mulberry' before.

If you are able to collect some and look at the spores you'd see if Bertia is likely. Hypoxylon spores are black (or very dark brown) when mature and are not septate. Bertia spores are colourless, have at least one septum , have rounded ends and may be kinked. Of course, life's not always simple and I have read of some relatives (e.g. a Lasiobertia in which the spore ends are pointed). AVH shows only two herbarium collections of Bertia. So, if it's Bertia (or a relative) a herbarium collection would be worthwhile.
