Observe pigmentation of the pileipellis hyphae in water mounts (some pigmentation dissolves in alkali solutions). Encrustations of hyphae are generally referred to as 'pigment' whether or not they are coloured.

If terminal elements of the pileipellis have large outgrowths, see Pileipellis terminal elements (surface).

Pigment may be present in other structures, such as cheilocystidia. This feature refers specifically to the hyphae of the pileipellis.

Choose this state if: there are fine to coarse encrustations on the exterior of the hyphae. Encrustations can be spiny, warty or peg-like. They can be arranged in more or less continuous rings or spirals. Encrustations are also referred to as epimembranary pigments.
