Frosty fibrecap

The crowded gills have a finely toothed edge and an adnate attachment to the stem. Inocybe maculata has a conical or bell-shaped cap which is up to 8 centimetres (3.1 in) in diameter. As the mushrooms age, the cap becomes flatter, and the broad umbo becomes prominent. The centre of the cap has white remains of the universal veil, especially on younger mushrooms. The cap is covered in fibres which extend from the centre of the cap to the margin (which is usually split). The cap is typically a chestnut brown in colour, though it is paler towards the margin. As well as chestnut, the camp has been described as "Buckthorn brown", "snuff brown", "tawny olive" and "Saccardo's umber". Both cap colour and the presences of veil remnants are known to be very variable. In appearance, Inocybe maculata f. fulva has a lighter cap colour (typically more yellow to reddish-brown) and less (or even no) remnants of the veil on the cap. The gill attachment is adnate, meaning that the gills are attached to the stem along their entire depth. The gills are crowded, with white edges that are finely toothed. Younger mushrooms have gills that are greyish-white that eventually mature to an olive-brown colour. The stem is up to 8 cm (3.1 in) in length, and generally cylindrical in shape, though it is often thicker towards the base. While the stem is initially solid, it later becomes hollow. There is often a small bulb at the base of the stem. The stem has cream colouration, becoming gradually browner with age. The base sometimes white and powdery. The flesh is white.
