That’s a very good point.

Indeed, as a novice mycophile, I have found that all the variations among mushrooms of the same species, the frequent name changes (due to much needed research by the professionals), and the rapid metamorphosis mushrooms go through as they fruit and mature are the biggest challenges for me in making an accurate ID. On the other hand, those challenges keep the endeavor exciting. I’m indebted to you again for the education. THNX

I wonder if…

similar to the ringed Armillarias, perhaps A. tabescens also represents more than one species? On the other hand, what I have IDed as A. mellea exhibits variable stature and cap color.

How ironic, Dave.

I just entered another observation (195886)which I ID’d as A. tabescens. Could these possibly be the same mushroom in different environments and at different developmental stages? I will attach a few more photos showing the caps more clearly and a spore print I have for this obs. THNX
