Notes: Overall, to my eye, the cap is white with the slightest tinge of purple/grey. Forked and abruptly ending gill patterns. Growing solitary in a hard packed soil amongst pine and leaves in a pine tree plantation.
cap 8.5cm in diameter, striations to 1.8cm.
stem 12cm in length and 1.5cm wide at apex to 2.8cm at base.
Scaly at base, smooth apex.

Thanks for you notes here, I never found anything that looked close enough to suggest.
Marginal striations as ratio of radius are 1.8/4.25 or 0.4 – 0.45R. In A. protecta, this ratio is quite a bit smaller — 0.1 – 0.25R. In A. protecta, you usually find gray to nearly black fibrils rather densely covering much of the stem. The volval remnants are rather hard (often rather like an eggshell’s texture). The whole fruiting body is very liable to ochraceous staining as well.
In the present case, not only is there a well-formed calyptra on the cap, but the volva is soft enough so that the expansion of the cap has stretched it outward and pulled it upward…tearing it from the base of the stem…at least in part.
I noticed that there is reverse forking present on at least one gill (forking with the open arms of the “Y” pointing TOWARD (rather than away from) the stem. Let me see what PNW Vaginatae have “reverse forking” reported…if any.
