looks VERY different from Oregon. Difference in climate niche?

In Oregon, NATS has collected several over the ridge from Falls City. True rainforest (over 210"/yr) has many other relatively rare hypogeous species, including Fischerula subcaulis.

These remain important collections, Thea. Glad you have preserved it.

I have the specimen…

It’s dried and will be scoped soon. It’s consistent with my observation 76776, as well as the other A. crassa observations – which should be transferred to G. crassus; we’re only about ten years behind the literature on this one. Oops. It’s quite common some years, some places in the California mountains. Sure, it is mostly hypogeous, but one finds it in the same way as one finds most mushrooms in the Sierras in summer – by looking for small bumps or cracks in the duff.
Fresh specimen was roughly 5 cm in diameter, 1.5 cm in height including stipe, which extended a little more than 0.5 cm past lamellae/gleba.
There was white latex, but it was so scanty as to be practically nonexistent, as would be expected in a dry year such as this. Some brownish-yellowish staining developed slowly on broken/cut surfaces. Acrid as hell. The odor to me was faintly sweet-fruity in a similar way to many acrid Lactarius and Russula. Certainly not benzaldehyde/maraschino like R. fragrantissima and its ilk, nor fenugreek/maple syrup like L. rubidus, etc.

How large was the pseudostipe?

Another 1/2"? Doesn’t appear to have been predated on by animals yet. How did you happen to discover it?

It was about two and half by a little over half an inch. The friend I gave it to is a far better taxonomist than I and hopefully was able to preserve it.

the approximate height and width of the specimen, Christopher?

Good questions

This was a pretty old and dry specimen when collected. It does have a pseudostipe, my pics of it got accidentally deleted and I already passed this collection on to a friend. If She still has it i will grab some clear pics for you and will try and get some microscopy done on this. The sweet smell was faintly of cherry lip balm scent . I’ll get some more opinions on odor as well.

I said ground when truly it was woody debris mixed with soil that was very dry and airy.

Thanks for the help dan!

Where’s

the latex? Where’s the stipe or pseudostipe? Gastrolactarius should have both features. The “slightly sweet” scent makes sense, sort of. Sweet like Marachino cherries? Or raspberries? Or lime jello? Or something else?

Wouldn’t be Arcangeliella. That species has copious white latex when sliced, is never is found “several inches underground”. Also, Arcangeliella would be tiny: about 1/2" across and about the same high. At least that’s what I’ve found in Oregon. One reason they are so rarely reported. A super-large specimen might be 2-3 inches across, but would rarely be found.

I like the name

Gastrolactarius, it makes much more sense. Also forgot to mention the slightly sweet scent similar to species in the genus Lactarius.
