Peel bark and see what you can find.

As an exercise, look under the bark around the next clump of velvet foot that you identify and find. Not many seem to take this kind of photo. Here is another one — look at the smaller ones to the left:

(from Tom Volk’s website) show light colored stems that appear to have been covered by bark, which is the reason suggested by Patrick for the paleness of the stems in this obs.

There’s no problem with the stems

As you can see in my obs. http://mushroomobserver.org/120695?q=1CwV3 they can be even all yellow when young (mine were on a dark place).

The problem (if any!) is the color of the caps that is to brown to the color of the stems, perhaps weather could be responsible for that (sudden sunny days).

It’s always more complicated to ID pulled mushrooms, isn’t it?

Here’s an obs that I had IDed as F. velutipes.

One similarity to 132296 is the “tap root.” I believe my collection was partially fruiting from buried wood. The tree type was elm, a favorite host for F. velutipes. The stipes on my collection (linked above) are not all that dark below. Perhaps we should consider another species name within Flammulina. I recall a few discussions about this… but I forget which exact observations.

formation caused by high CO2 concentration (see Stamets, Mushroom Cultivator) AND low light AND crowding (= small growing space).

The stipe color remains the problem. What would cause the cap to turn brown, but the stipe to remain light colored instead of turning dark velvet? Where is the clumping seen so readily in enokitake? You state they are “very young”. Perhaps add shots taken later when specimens more mature?

These are very young

These are very young, and were just starting to emerge from
beneath the bark (caps are about 1/4 inch — macro shot). They do
not turn dark and velvety until they are older and exposed to the
light. This paleness is the same effect that is desired
by cultivators in Japan who keep enoki (F. velutipes) in
the dark.

Still don’t look like F. velutipes, aka Velvet Foot.

Where’s the velvet on the base of the stipe? Compare to obs. 119560, 122338, 118678, 116008, 113918.

There is something else which has been identified as F. velutipes on MO, but I find that name suspect. F. velutipes should have a velvety stipe base, hence the occasional common name of Velvet Foot.

Substrate and locale seem right. Just saying the mushroom doesn’t look right.

That is a mossy log

— very likely cottonwood or possibly maple, in the river bottoms.

which I’ve only found on wood. These look like they were growing on the ground. Were they?
