Observation 211376: Tricholoma (Fr.) Staude

When: 2015-07-26

Collection location: Westford, Middlesex Co., Massachusetts, USA [Click for map]

Who: Jim B (yakhunter)

No specimen available

I found this mushroom while looking for Chanterelles in a mixed hardwood/softwood stand of mature white pine and red and white oak. It was in an area of a lot of rotting stumps, but was not on dead wood that I could see. It was growing singly, in pine needle/leaf litter.

Soils are very well drained, and along the edge of a beaver pond, but several feet above water level.

Gills did not leak any latex or anything noticeable when scored.

Smells earthy (and mushroomy and like it may be delicious!). I left it for two days on white, pink, and blue paper and there is NO noticeable spore print.


You can see where I scored it to see if it leaked anything. The brown line to the right of the stem. It bruised this color after a while.

Notched gill attachment…

supports the Tricholoma proposal. Also, it appears that the gills show a bit of brown staining, which also supports Tricholoma. I usually don’t see the brown-staining Trichs until mid autumn. But this summer I have seen other mushroom types that generally don’t appear until fall. Cap surface on the on seen here does not look like Tricholoma to me.

Thanks Dave W. Like I said, the gills on this one are pretty firmly attached but it is not fresh. Perhaps they tore more easily when fresh. Other differences I see from your specimen are the 2-colored stem, the non-central stem (mine is on one side of the cap, but perhaps that is just individual variation), my gills have a pretty distinct notch where they connect to the stem. Also, you can see the splits int eh cap on mine. Those were there when I found it growing. It looks like when bread or muffins bake and the outside doesn’t expand as fast as the inside, and it splits.

Also, the smell is quite strong and pleasant.

Leucopaxillus species…

are all terrestrial, as far as I know. Gills that are easily peeled/scraped away from the cap is a good diagnostic trait. Here’s one I just found last weekend obs 211581 that reminds me a bit of the mushroom seen in this obs.

The specimen is getting older and dried, but at this point, no, the gills do not separate from the cap flesh easily. Also, it does not key out well under Leucopaxillus. I get all the way to the end and the last 2 choices talk about the size of the pores and the mycelium on hardwood or softwood. I found it on the ground.

Fracticum has a slimy cap anyway, right?

Looks a little like Tricholoma fracticum

but you don’t get that in the east.
