Luminoradiata Mysticopsis, named for its distinctive glowing radiance, features a robust basidiocarp with a convex to flaring cap (10-25 cm) that is smooth with a bluish tinge and scattered orange pustules. Its dense, adnate gills emit a bright blue-green bioluminescent glow (450-495 nm). The sturdy, semi-translucent stipe with longitudinal striations shows faint luminescence from luciferin oxidation by luciferase. Thriving in temperate forest understories at 5-25°C, it colonizes decomposing leaf litter and woody substrates. As a member of Aetherium Arborescens (Mycophyllaceae, Agaricales), it shares luminescent traits. Spores disperse passively via wind through prominent gills. The extensive white mycelial network supports saprotrophic nutrient cycling and decomposition. Data deficient due to limited observations, L. Mysticopsis provides insights into fungal bioluminescence and forest ecosystems.
