Observation 72663: Lactarius Pers.

When: 2011-07-24

Collection location: Ringle, Marathon Co., Wisconsin, USA [Click for map]

Who: arebella (arebella)

Specimen available

These were growing on the ground, but appeared to be attached to the roots of the nearby Basswood tree. No Poplar around the immediate area, so I don’t think it’s a Pleurotus Populinus. Nothing was growing ON the tree itself, but the tree is dying and has decay at the base of the tree.

The mushrooms were lined up fairly tightly, some were still sprouting up and some were fully mature and approaching past their prime. The largest was about the size of my hand. Distinct heavy gills, hearty looking mushroom.

Smell is a pleasant, pungent but not typical mushroom smell. It didn’t smell like licorice. The flesh was solid and was a cream color, slightly bruised probably due to aging. When removed it took some effort as it was attached to wood. The stem is very short.

It doesn’t fit the profiles I have seen, not so pristine, perfectly shaped and obviously on a vertical surface like an oyster, but it looks like that’s what it is with it’s fan shape.

I’m not sure of the species, I’ll throw in a guess and I’m sure to be wrong!

Thank you for being so kind. I’m really trying to get this stuff. Don’t know why, but I like to research mushrooms and see if I’m right. So far, not doing so well, but I’m learning.

I have these in my refrigerator. Of course, not in an area where anyone gets to!

I cut the sample, no liquid, milk, nothing. It could be that it has dried out.

I remember my daughter wanted to trample them and started to kick it. One of them she knocked the top off of and I did examine it. I didn’t see any liquid.

I still don’t know jack, if I can, I’m only going to pick your brain a little so I can learn more. Does this mean anything classifying as Lactarius if it doesn’t bleed from damage? I should say, if all signs point to Lactarius, but my sample might not be the best because it’s not milky/watery, then it still could be?

I might send my parents out and make them beat up a fresh one just to see for sure. It’s in their yard.

Thanks again for your time!

Good documentation on this one! Especially when you are not that familiar with identification,looking to see what it was growing on, and adding everything you observed at the time.

My ID comes from the fact that if you blow up the second picture, you can see some white droplets on the gills near the bottom of the mushroom. This is an attribute of the milk mushrooms (lactarius). If you damage the gills or slice them, they often lactate. You can taste the liquid to see how hot, or acrid it is, and sometimes it will stain the gills a different color after some time.

There is cross veining on this one (in between the gills) so that should be a good ID tool.
