This looks very like an Armillaria sp we saw yesterday further south from your sighting, yet ageing growing in a similar manner from wood, some living and some dead - I hesitate to try for species, sorry
I've just had a look at your page again - your photos and recordings of fungi are spectacular! A really stunning collection reflecting the beauty, diversity and strangeness of this kingdom.
Thanks Lisa, the Eurobodalla has an extremely rich biodiversity, specially in this kingdom, which many folk are totally unaware of. Even after all the years of looking at this field, we still find ones we haven't seen before; always so exciting. T
