no DNA confirmation that this mushroom IS acutoconica.

slimy (“extremely slimy,” according to Alan) stem not typical of H. acutoconica, no traces of its normal coloration, just a pale green color (I have also found this unknown species at JMP, but it was not with typical orange forms of acutoconica nearby).

but it was growing next to acutoconica. gosh, that proves it, then. and b’god, it has a conic cap, too!

I suggest that we not ASSUME and dig a big deeper.

odds are that they are just a white acutoconica, then.

but it’d be good to KNOW.

I put it into the PCR

I haven’t checked to see if the PCR reaction worked yet. They did not change color in the 24 hours I had them before they went into the dryer.

did you run the DNA on these Alan?

hopefully NOT while driving?

did you keep them in a fresh state? did they darken with time? because certainly a white form is possible for any mushroom, but these did indeed have a mere tinge of GREEN at the cap apex in hand, not the expected orange/yellow of acutoconica.

DNA confirmation of species would be interesting and useful here.

They certainly have the aspect of acutoconica though, not to mention that “guilt by association.” I can see the typical splitting of the stipe base here. In your photos, they do look a bit yellowish on the cap, rather than that ghostly white with a hunt of green in hand in daylight that I observed.

White Hygrocybes

Hygrocybe albinella, which was described from Bolder Creek looks like this, has spores over 12 um long and a dry to moist stipe.

Humidicutis pura (=Hygrophorus purus) has a viscid stipe and spores under 10 um long, on average.

BUT… I think that some Hygrocybe have “albino” forms; and that this is H. acutoconica… I have found white singeri before.
