Collection location: Sweet Valley, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

Notes:
Edge of grove of Virginia pine (possibly also Scotch pine). One small Norway spruce close to where this mushroom was found. Absolutely no hemlock in this area.

Spores mostly globose to subglobose, a few broadly ellipsoid. Approximately 8-10 × 8-9.5.

Absence of any evidence of partial veil suggests A. albocreata as a possibility, and the relatively long marginal striations (~0.3r) support albocreata. But this specimen lacks the distinct basal collar on the stipe that is expected with albocreata. Also, spores are a bit larger than for albocreata. Occurrence early in the season supports praecox.

I suspect that A. praecox, which is primarily associated with native eastern hemlock, has spread to planted Norway spruce. This location is only about one mile from my home. I’ll check for newer fruit bodies in a couple days.
