First of the year for me.

Retuclations on stipe, most notable on larger one.

Colors are likely faded/altered after two days of hot dry weather.

Edge of a mossy lawn, hemlock, oak, and birch present.

Ammonia dark on cap surface, pale orange on cap context.
KOH: dark mahogany on cap surface, rusty orange on cap context (and tubes), dark on stipe surface.

Spores ~ 12-16 × 4.5-6.


Top row ammonia: cap surface, cap context, stipe surface
Bottom row KOH: same sequence.

I don’t recall finding any red-pores. (Several found in other hemlock areas of Ricketts.)

Maybe this is something other than subvelutipes, but there have been observations with reticulate stipes for which evidence suggests subvelutipes, eg. obs 248500. However, the fine netting on 248500 looks much different than the coarse reticulations on this one (278840). Actually, only one side of the stipe on the larger mushroom seen here had the netting. Third photo down shows the punctate/ribbed pattern on the other side of the same mushroom.

I’ll modify my subvelutipes confidence here. But the idea of subvelutipes as exhibiting highly variable morphology seems increasingly plausible to me.

The darkened cap surface is fairly common in hot/dry weather. Here’s another example, obs 245072.

I dunno, Dave

Too much reticulation for subvelutipes (could be a developmental oddity rather than a species trait), the cap colors are off a bit, but this collection surely fits the ‘group’ pretty well. Can you think of anything you found at this spot in 2016 and posted to MO?

I will be SO happy when we can stop using the word “group”!

I know we have to do it. I get the reasons. But it feels like cheating.

BTW, were these really young? That’s a lot of yellow in the pores compared to what I see in Pittsburgh. Ours will have a yellow ring at the edge when young, but the pores usually mature in solid colors moving outward from the stem rather than this kind of mixed darkening. How important a feature is that?

P.S. Great shot of the yellow velvet down at the bottom!
