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.
