Observation 26424: Armillaria mellea (Vahl) P. Kumm.

This was growing on an old stump that was fallen over leaving a mound of dirt many years ago. It looks some what like a honey mushroom but there is a very yellow tent to this . This yellowing will stain your hands. These Specimens are immature but it looks like they will develop a annulus ring when opening.. The stems measure from 3 in to 7 in tall. somewhat fibrous.

Pointed bases, smooth cap, and yellow coloration are the key to ID of A mellea. A solidipes also has pointed bases, but has fibrils n the top of the cap and tends to be brown and paler.

usually has a very hairy or warty cap. The color is right in this observation but I still think it is A. mellea. A. sinapina usually ocurs singly or in twos or threes. This complex is very difficult.
