Proposed Names

28% (4)
Recognized by sight: With pink spores and wood rotting habit, Pluteus as a genus is a good guess, but cervinus isn’t a white mushroom. Barring genetic studies or some serious microscopy, I’d go with the similar to cervinus, white Pluteus sp. pellitus.
Used references: MDM, Arora.

Need to see details…

Excuse, let me put down my book that I just had my nose in… There we go -

But with my limited experience in Pluteus there is a lot of importance put on cystidia shape, and a photo of a cystidia here would answer quite a bit. After that there is details on the hyphae in the cap surface, amount of pigmentation, and existence of clamp connections (I think I remember that…).

It would be good to see these details in any case, if this is P. cervinus it would be interesting to see these details and confirm that P. cervinus can be white. Or if it isn’t, then it would be interesting to know what it is as a white Pluteus, and help us all out. I know I would keep my eyes open for white Pluteus in the field. (Well, when I don’t have my nose in a book that is…)

I think we just saying that this one looks more interesting than just saying it is a P. cervinus.

Ok, back to my book now, where did I put it, ah there it is…

…is a great guy and a fine mycologist, but his Pluteus cervinus page actually shows a white Volvariella, not a white Pluteus cervinus, to show how people can MAKE MISTAKES. Even the best of us.

This is a feedback forum. Expect to have your IDs questioned. I find that it improves my abilities to identify future fungi to have my preconceptions questioned. Don’t take it personally, and don’t expect a pass. And by the way, your exclusive patch of jacksonii could sprout anything, eventually; complacency is a killer, too.

there are pics on his website with this species having the same cap color, i shouldnt have used my flash on this one and should have taken sum pics from above so the dark center of the cap could be seen.

It was the pins that gave it away, classic cervinus im sure of this. The pins have darker caps. Being waterlogged changes the appearance of mushrooms.

Not all species are text book i would think that with the amount of well educated people on here they would know this. Rain has a number of affects on how mushrooms look as well i can show tons of pictures of mushrooms that are the same species but look totally different cuz of being rained on. Maybe people need to take there nose out of books and spend a little more time in the field. I hunt 3-5 hours sometimes more daily, im not saying im better im just saying the more time in the field the more you notice how differnt mushrooms of the same species can look. Substrate, moisture content, sun exposure, exposure to the elements all these things make mushrooms change in appearance.

Cuz of the spore print color, habitat, i also had it Id’d on another website and all things point to that genus species. Gill attachment was free, print was salmon/pinkish color

Why are you calling this Pluteus cervinus?

Gills, spores?

Did you get a shot of the gills? And esp. the gill attachment to the stipe? I thought P. cervinus needs to have pigmented radial hyphae in the cap surface, I don’t see that here.
