Observation 210705: Lactifluus subgenus Lactifluus
When: 2015-07-19
No herbarium specimen

Notes: Smooth, white, convex, 3" cap with eccentrically attached stem. No gills at all on one side. Non-staining on cap and context of cap and stipe 6 hours later. Gills thin (to 5 mm), regularly forked, also non-staining. Context slowly very bitter like Lactarius piperatus. Latex white, non-staining.

Found beside trail beside Lactarius piperatus without any forking of gills.

for a hike in 90+ temps and high humidity and was thus reminded of an for hike for a mush hike in SNP and again recognized an apparent truism: It is very difficult to observe mushrooms and talk with a group, even participate with a group, which I was obliged to do. There were a lot of big white mushrooms around. From the trail, they looked vaguely like L. piperatus. In fact, one of them was very hot, though the gills were not as close as in some of the photos in field guides. I was attracted to this one by the solid ‘velutinous’ appearance from above and by it’s location very close to the trail. The predominately oak leaf litter was several inches thick, but the cap was clearly visible. No way to see under it though, so I flipped it over. I have never seen gills with that level of ‘promiscuous’ forking. I don’t remember an odor, but I can try again tonight. It appears well preserved as of this morning. The taste was not as quickly hot as L. piperatus.

Hah hah

You got me! I got a collection of M. ochricompacta in the Smokies this past week. I guess I’m really stoked on Multifurca right now. What a crazy genus!

What a strange one

The promiscuous forking and dark shade of the gills with a white cap does suggest Multifurca, however M. ochricompacta is described and reported as having no milk. Hence its original placement in Russula. The cap is also laking zonations that typically extend into the context, which is typical for members of Multifurca. I would also expect the cap surface to be far less velutinous, though this may be because of the seeming immaturity of this fruitbody. I am unaware of any Lactarius or Lactifluus that would typically have this sort of forking. This might be an aberrant fruitbody. Why is it lacking gills on one side? Is there any evidence of gastroidization? Another tell-tale sign of M. ochricompacta is the distinct odor of citronella or a lemony cleaner, which is not mentioned. You also mention that the taste is bitter like in L. piperatus. L. piperatus is extremely acrid, which you are likely to notice when you taste the milk. L. deceptivus is a member of subgenus Lactifluus that is reported as occasionally mild, though I don’t know about bitter.

GibbiPicasso, you are amazing!

I thought you might never see it and you caught it in less than an hours. Thanks!
