Found in manured soil in a box garden. Physical morphology fits within the extremely variable Panaeolus cinctulus with only a few minor inconsistencies: The pileus seems thinner and does not darken noticeably near the margin, rather it remains watery-striatulate, The lamellae are distinctly reddish brown in immature specimens (will update with photo), and the stipe is a very light tan color beneath the pruinescence and completely lacks longitudinal striations.
