The note, often referred to as oakmoss, presents a complex olfactory tapestry that is at once earthy, damp, green, and slightly woody. Its initial impression can be sharp and bracing, reminiscent of cold, mineralic stone in a deep forest. This quickly softens into a velvety, mossy texture, evoking the rich, loamy soil beneath ancient trees, often with a subtle hint of dampness or petrichor. There's a profound greenness, not the bright, effervescent green of spring leaves, but a deep, somber, almost inky verdancy. As it evolves, it often reveals leathery nuances, a touch of dry, almost papery dustiness, and a melancholic sweetness akin to decaying leaves. Its projection is moderate but its longevity is exceptional, anchoring compositions with its tenacious, grounding presence. It functions almost exclusively as a base note, providing an unparalleled depth and a sophisticated, slightly bitter-green counterpoint to lighter elements.
