Mycena urania, also known as the Violet Bonnet, is a small and delicate mushroom that captivates with its striking colours and ethereal beauty. Found primarily in moist, shaded environments, this species features a translucent cap that ranges from violet to pale lavender hues, often appearing almost luminescent under the right lighting conditions. Its slender, fragile stem adds to its enchanting appearance, making it an interesting find among mushroom enthusiasts and photographers. The mushroom is known to occur in various regions across Europe in late fall.

Cap initially conic in shape, and expands to hemispheric in maturity, with sulcate and translucent-striate characteristics. Initially pruinose and glabrescent, it starts as a blackish violet and gradually changes to bluish grey or greyish, sometimes with a subtle violet tint. The centre remains dark grey, eventually shifting to shades of grey or grey-brown. The flesh is whitish and thin. Gills extend to the stipe, ascending, and are narrowly adnate to slightly broader adnate, but not decurrent with a tooth. In young specimens, they may appear violet-blue, later turning white to grey, sometimes with a brownish tint. Stem hollow, straight to slightly curved, cylindrical, and uniform in thickness. It is pruinose and smooths out with age, except for the pruinose apex. The colour ranges from lilac-grey to slate-grey, becoming darker towards the base. It has no ring. Spore print white or very pale buff.

Microscopic Features: Spores measure 7-10.2 x 3.5-5 μm. They are pip-shaped, smooth, and amyloid.
