Observation 198516: Lactarius hibbardae var. hibbardae
When: 2014-10-22
No herbarium specimen

Notes: Medium sized mushrooms found in an open field near Pinus virginiana. Gills attached with some forking near the stipe. Latex white, unchanging, not staining tissues. Considered L. hibbardae var. hibbardae, and L griseus, but I found no mention of forked gills in those species.

Yes there are numerous short and intermediate lamellulae near the margin. Also some longer ones. There is also some forking near the stipe. I zoomed in at full size and I noticed this on my home computer at various magnifications. I Should have done an odor/taste test in the field bur it was a very cold day and I just made it back to my car when it began to rain. Have to make a note to do this in the future. Also chemical test would be useful. Thanks for your input.

Looking at you photo at full size I see many Lamellulae (short gills)at the margin and possibly a couple forks. Can’t tell. Next time you find this, note the odor. Same as Lactarius mammosus.

think so. If the gills were single during their growth period, how and why would they start to fork? Again, I find no author stating that L. hibbardae…..has gills that are forked in any manner. As you say; mushroom identification is not always with certainty. Sais la vie. Not really sure what this may be, but perhaps I’ll find it again to study it further.

Second thoughts…

I think the possibility of L. hibbardae var. hibbardae occurring with forked gills should be considered. I wonder if the gill morphology changes as this type ages?

Phil, when I just glance at this…

my first thought was also L. hibbardae. But like you say, the gills on hibbaradae are different… not only the lack of forking, but these are too pale, too thick, and a bit widely spaced for hibbaradae. I find a lot of hibbardae. It seems to favor areas with species of birch. Almost always smells like coconut.

I also agree about ruling out L. griseus. This species is usually found in low-lying wet areas. It’s a small fairly fragile mushroom with decurrent gills.

I’m guessing that you made this collection in a spot that I also check occasionally… the rove of Virginia Pine adjacent to the baseball field in SV. I find a lot of interesting material there, especially late in the season.
