Observation 49272: Lactarius volemus var. flavus Hesler & A.H. Sm.

When: 2010-07-27

Collection location: Cranberry Lake, Westchester, New York, USA [Click for map]

Who: damon brunette (damonbrunette)

No specimen available

At first glance, i put in a photo next to Hygrophoropsis aurantiaca that i found just inches away. This lactarius had what i thought were forked gills. And the hue was nothing id seen before, a light orange through and through. The rolled margin was really throwing be for a loop. Then i thought i should slice the gills and voila… White latex that stains brown/black. Any ideas?

[admin – Sat Aug 14 01:58:25 +0000 2010]: Changed location name from ‘bedford ny’ to ‘Bedford, New York, USA


Irregular gills noted here.
Reaction of yellow with KOH
Rushing to judgement and placing with Hygrophoropsis aurantiaca

Used references: Keys out to this using Arora’s Mushrooms Demystified. Scant description, though: “…a viscid, pale yellow cap…” I would have expected some note of the pale lime-green gills.

Appears to have been taken in a forest, Noah.

Latex taste?

I think it’s because the picture was taken in the forest on a sunny day with the sun shining through leaves giving everything a green cast

Thank you for Lamoureaux’s photo.

It certainly does look similar in at least the cap coloration.

The problem remains those lime-green gills.

Don’t mistake it with L. volemus. L. volemus var. flavus is most likely a different species but it’s being called a variety of volemus

Here is Yves Lamoureux’s picture of it

I’ll also post an Ob of it

According to Arora

L. volemus should have a “tawny to orange-brown cap and stipe”. I see what appears to be light orange bruising on the cap, probably from handling. But most of the cap has no orange or brown that I can see. Noah, have you found specimens of L. volemus this light colored before?

heres the deal on this one…

went back and took the speciman out of my basket. Applied FEso4 and got a green blue reaction, same as volemus. Plus being that var. flavus is buff yellow not viscid as aspideodes. So im still rolling with noah on this.

oak, beech, maple…

The first and third pics show why i thought a ‘light’ orange, but maybe more yellow.Through and through meant cap gills and stipe all same shades. definately buff and brittle as the description says. I agree with noahs assesment.

Got me stumped. More information?

Did you notice what tree species were nearby? It would definately help in narrowing the field here. I don’t think the latex stains brown/black. It looks more violet/purplish to me, which might suggest L. tominosus, except there is no visible scales near the edge of the cap. Please expand on the comment: “… light orange through and through.” The photos don’t appear to show any hint of orange on your photos. Is the flesh orange?
