Observation 142766: Morchella tomentosa Kuo

When: 2013-08-06

Collection location: Clearwater National Forest, Idaho, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

My idea is that the blackness is a coating produced as the mushroom pushes up through the burnt ground. Rainfall and other erosion, as well as expansion of the mushroom, reduces the blackness and thus reveals the true color of the “grays” as being tannish-yellow (which accounts for the use of the name “blondes”). So, according to this idea, the “fuzzy foot” is the product of the combination of a grainy stipe surface and an ashy coating.

As the yellowish fruit body dries, the blackness on the stipe increases as a result of the ashy grains compressing.
