Unidentified Agaricus Mushroom?

Hi,

 

I have come across some Agaricus family mushrooms that are growing on wood? I can't seem to find any references to a member of this genus growing in this habitat? Any help would be appreciated in identifying this mushroom. Cap; up to 12 cm across, becoming buff coloured and cracking with age. Stipe; non-bulbous, with a large persistent ring. Gills; pale pink initially then dark brown with age. Flesh turns yellow quickly when handled. Growing on a very old and rotten tree stump, no idea what type of tree.

 

Many thanks.

      Hi,  I'm not sure if this helps but I found some similar Agaricus mushrooms recently and had lots of trouble getting a positive ID.

       

      If you haven't already - I'd take a look at Agaricus xanthoderma var.lepiotoides and Agaricus moelleri as possible options.

       

      Good luck!

      Ivan

          Hi Ash,

           

          The mushrooms I was referring to were growing in woodland, and close  to trees, but not directly on wood. I'm wondering if perhaps some  Agaricus that are used to growing on wood debris aren't that fussy and  can grow directly on a stump...? I've attached some pictures here. It looks like from your picture 7 that the stipe is bulbous at the bottom, but I'm not sure how that helps the ID.

          I'd be interested to know what you find out!

           

          Ivan

                Ah mystery solved, congratulations!  You can see some evidence of the yellow staining in pictures 7 & 8.
                The scaly cap confused me, though I understand that may make it the variation Agaricus xanthoderma var.lepiotoides rather than the standard
                Agaricus xanthoderma yellow stainer.
