Appears to be based in the ruins of a previous basidiocarp emerging from the top of a large cut stump- likely a tropical rainforest tree. Red guttation but quickly bruised grey then black. Pyrrhoderma?

Phaeolus? Coltricia? 14cm wide and 9cm high above ground. Cap brown, appearing more red-brown under artificial light. Thin yellow margin, more visible on pore side. Velvet lighter coloured stipe; ovoid in cross section. Pore surface, tubes and context brown; white patches on pore surface may be a mould. Pores irregular. Growing on and through small sticks and grasses beneath 2 dead trees. May have extended deeper to tree roots but structure fragmented by other materials and white ant activity. (I think this is the 5th one of these I have seen this season)

This was a relatively long lived fungi living in this condition for over 3 months. Back in 2018. It was-still visible where it has been by having a thin leathery form with quite fibrous appearance 2 years later finally decomposing to a gue like grey mass.
Note one photo also shows a Fistulinella mollis in the photo.
