Microscopy:
Pileipellis: Consists of 3 layers:- an upper layer consisting of thin interwoven hyphae, followed by a layer of thick parallel hyphae and a lower layer of thick interwoven hyphae, several crystals embedded between hyphae.
Gill trama: Regular.
Cheilocystidia: Absent.
Pleurocystidia: Chrysocystidia present.
Caulocystidia: Uncommon filamentous.
