Habitat

A mycorrhizal fungus that associates with deciduous and coniferous trees, though less often with the latter.

Overall structure and growth

Lilac fibrecap (Inocybe lilacina) fruit body

A small mushroom that appears in groups, which can contain a few to very many specimens.

Cap

The cap of the Lilac fibrecap (Inocybe lilacina)

The lilac cap, which pales with age, starts off conical and flattens with time. It has a pointed central umbo, which is often tinted brown. Fibres radiate out from the centre of the cap. As the fruit body ages, the cap splits along these fibres.

Gills and spores

The gills of the Lilac fibrecap (Inocybe lilacina)

The gills, which can be sinuate or adenexed, are very pale grey, almost white, at first. As they age, they turn clay brown, which is also the colour of the spores.

Stem

The stem of the Lilac fibrecap (Inocybe lilacina)

The stem can be white with a lilac flush or lilac. It often turns clay-brown as it ages. Between 3 and 6mm wide, it can reach 6cm tall. The base is sometimes fibrous.

Flesh, smell and taste

The flesh of the Lilac fibrecap (Inocybe lilacina)

The flesh is grey-white with a lilac flush, with stronger lilac colouring at the margins. Odour is mealy or earthy. Although taste is recorded as mild, it is not advised to taste this mushroom as it is deadly poisonous.

Possible lookalikes

The amethyst deceiver (Laccaria amethystina)

The edible Amethyst deciever (Laccaria amethystina), pictured, could be confused with the Lilac fibrecap due to their similar colouring, growth habit and habitat. However, the Amethyst deceiver has distant (widely spaced) gills, which are a deep purple, not grey-white to clay-brown.

Always stay safe when foraging. You need to be 100% sure of your identification, 100% sure that your foraged item is edible, and 100% sure that you are not allergic to it (it is good practice to always try a small amount of any new food you are consuming). If in doubt, leave it out!
