 The gleba typically has sharply defined basidia-bearing sectors, which are partitioned from one another by sterile veins, and in which the basidia are regularly scattered through the tissue.The gleba, which is brown or white in young specimens, turns dark purple to brownish purple in age, and crumbles to a powder of spores and disintegrating tissues at maturity.The basidia are roughly clavate (club-shaped).
