Multiscale Spatial Pigmentation Profiles in Dacrymycetes-like Fruiting Bodies: Raw Images, Shape-Adjusted Profiles, and Spectral Analyses

<p dir="ltr">This dataset contains original scanner images and derived spatial-profile data from two morphologically distinct Dacryopinax/Dacrymyces-like fruiting bodies collected on 20 September 2026 in the author's grandfather's privately owned forest.</p><p dir="ltr">Each biological specimen was represented by two technical scanner views and analyzed along a normalized body axis divided into 100 spatial bins. The dataset includes spatial profiles of hue, saturation, brightness, CIELAB L*, and CIELAB b*, together with image-derived local morphology measurements.</p><p dir="ltr">The accompanying analyses examine technical-view reproducibility, spatial coherence, morphology–pigmentation relationships, shape-adjusted pigmentation residuals, polynomial detrending, high-pass spatial components, and multiscale Fourier decomposition.

Phase-randomized and hierarchical surrogate analyses are also included to evaluate whether observed spatial correspondence can be explained by profile smoothness or technical-view dependence.</p><p dir="ltr">Across the two specimens, pigmentation showed strong spatial correspondence despite substantial differences in gross morphology. After removal of morphology-associated variation and smooth positional trends, residual spatial correspondence remained at selected spatial scales.
