appearing fibrous is due to it sticking to the gill edges and ripping apart as the cap expands. Here’s an old post of mine showing a similar example where the specimen represents A. muscaria var persicina.
remnnants are floccose on the margin, and the UV remnants can be pale yellow to tannish and as you can see, it left a ring on the apex of the bulb and on the stipe proper. These morphological featyres match A. guessowii.
The grayish UV deposits on the stipe bulb seem a little dark for muscaria. Also, the partial veil looks to be rather fibrous.
Otherwise, this looks like muscaria var. guessowii.
