No specimen available

Growing out of south shoulder (bladed) of dirt road (Swift Trail) after several days of rain (6"+); mixed spruce-fir-pine association with some hardwoods. Note very robust size, thick context. Mild odor, no yellowing at stipe base (nor pileus edge) or other distinct staining after slicing/rubbing, although a small bit of “scales” at the side of the bulbous stipe base (1 specimen) was yellowed (bright, but very small area) when picked. Taste fresh was mild; edible and very good cooked. All of the images were from a single “string” ~1m long. Saved partial specimens to be dried and placed in the Univ. of AZ collection.


two specimens with opened partial veils, the smaller had darker spores (i.e. more mature).

Per Rick Kerrigan to whom I sent photo’s shortly after collection, this is probably undescribed.
