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.
Here is a link to some new pictures! I'm also looking at other help with the ID too.....very frustrating as I'm still none the wiser? Can anybody help me with this? Is this is a rare or even a new species based on its habitat?
Thanks again in anticipation.
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.
Thanks for the reply. Neither of the two you mention grow on wood, in fact no Agaricus grows on wood and this is where my ID issue lies. I'm in the process of drying some specimens to send to the Mycology unit at Kew gardens to see if they can help too. I contacted Roger Phillips and it caused him some interest too! Be exciting if I've discovered a new species, or even a new habitat for an existing one! Were the ones that you found also growing on the stump of a tree too??
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!
Hello again Ivan,
One of the pics looks similar. This really has me lost!! I have sent some dried specimens/spore print/photos to the mycology unit at Kew Gardens on the advice of Roger Phillips, as he too was quite interested by this discovery. He has confirmed what I already knew, in that no identified species grows directly on wood itself. If you take a look at these latest pictures (as there has now been 3 separate fruitings since I first posted here) you can see exactly what I mean. As soon as I find out what they are are, I will post something on here.
All the best,
