Amongst pine would be an unusual place to find Melanoleuca melaleuca. – It’s more of a grassland species.
Did you do a spore print? – Should be pale cream colour: –
NB: I find that doing spore prints on microscope slides gives best results as you can then put different coloured paper behind the print so as to better see it.
When determining colour, the spore print should be scraped together into a small pile, and then pressed flat to give a solid colour to work from. (Using the edge of another microscope slide for this, and then pressing the pile between two microscope slides is ideal)”
