Have had a number of these fungi over a fairly small patch (the same area as the Chiloglottis patch). Appears to grow as a 'standard' brown gill fungi with a yellowish ring, then white ?hyphae completely cover the fungus.
80mm diameter, very solid. I cut open a damaged one - they have gills developing. Growing in mixed Kanuka-Broadleaf-Podocarp forest with one beech tree nearby. Will go and have another look next weekend to see how they have developed.
Abundant on fallen branches in a patch of radius roughly 1–2 m. These had appeared within the last 11 days and are the first I've seen along the track this autumn.
