Yeah, the yellow…

reminded me more of Validae than anything in Lepidella. But the tapered rooting stipe base doesn’t bring to my mind anything from Validae. I attempted to get a spore drop, with the intention of bringing some spores home to view under the scope. But that didn’t work out.

Looks like this one will remain a mystery… at least for the time being. It’s likely I’ll return to this area some year in the future, likely at a similar time of year.

Flavorubens with an atypical stipe base seems to make the most sense here.

The cap…

looks like yellow pigment might have been washed out by rain. That’s not uncommon with flavorubens


Well, this is unusual…

Yellow volval warts similar to those on a number of species such as flavoconia and flavorubens (and their ilk) and remnants of a membranous partial veil on a species with a notably elongate or even radicating bulb on the stem base together suggest section Validae to me.

I hope you see another one of these one day.

Very best,
