Notes: Large barrels, golden to reddish brown. Surface sometimes even, but usually with numerous irregular, finger-shaped, pyramidal or lamellated projections. Top usually thin-walled, usually also with projections. Interior of atria rough, as a bubble-like pattern. Zea (1987) synonymized X. rampa (de Laubenfels, 1934) with this species, but more recently Rützler et al. (2014) described it as a good, separate species.
