Type species

Palliocystidium chlamydatum .

Diagnosis

Differs from the genus Subulicystidium by cystidial encrustation pattern: regular chains of rectangular crystals absent but plate-like to irregular oblong crystals present.

Etymology

Pallium (Latin, noun) – cloak, and cyst - (new Latin) + - idium. Referring to flat oblong crystals covering cystidium, resembling the way the cloak covered the body of the ancient Roman.

Notes

In both species currently recognised as Palliocystidium , clamped septa on the cystidia were found. These septa are especially easily observed on cystidia nearly devoid of crystals, i. e. due to young age. On the contrary, the crystalline coat of older cystidia hinders the observation of septa and clamps.
