Actually, I’ve done a little reading on Melanoleuca today,

and “M. alboflavida” may not be quite the slam – dunk that my manuals have led me to believe. For one, M cognata is now being reported as widespread in NA, as opposed to the western distribution that had been previously reported. Kuo’s comments suggest the genus is due for a NA update.

Here’s a link to a recent MO post of a small specimen with spores smaller than observed in my post (102308) for which the collector currently expresses doubt about an alboflavida ID.


Over the years I’ve seen many examples of what I call M. alboflavida. I’ve even sampled some for edibility, and have found the caps to be pretty good. For the time being I’ll continue to call this type “Melanoleuca alboflavida.” But thanks for stirring my curiosity on this one, Richard.

sorry, just noticed the notes and spore measurements.
L. alboflavida looks good.

Richard, is there something about this mushroom…

that leads you to believe it is other than an example of L. alboflavida? Just wondering because your proposal came in after I had posted my ID.
