Hi Walt,

Thanks for your comment, from which I conclude that maybe the id of these specimens was a bit precipitate. At first I made no ideia what it could be. When I saw the spores, looked very similar to those of Pleurotus and searching for similar photos I end up with P dryinus. The dimensions are correct, but it seem that that species has more irregularly shaped spores than those observed. Regarding the morphology, the yellow colour is present at the gills and also appeared at the border of stem when cutted. On the other hand, these were found after two week without rain, so they looked a bit too dried.
I will try to go back to microscopy to observe further details and for now I upload some photos from the cuticle obtained before.
Thanks again and best regards,
zaca

I am not familiar with the species you have photographed. It reminds me of Neolentinus or Lentinus.

This is our Pleurotus dryinus but a bit more yellow than normal. It has a partial veil which soon disappears and the cap can have a glazed appearance.

So,
