In Alter | Altar, Bryson provides an immersive sculptural environment to act as a platform through which viewers may physically step into and be a part of the process of mycoremediation. This 9’ x 7’ x 12’ sculpture was built out of wooden hexagonal frames and glazed in waxed and naturally-dyed canvas, and polyethylene sheeting. The exterior materials were tightly stretched over the wooden frame so that the interior was sealed, making it humid and hospitable for the biological materials living within. Bryson collected mine-waste from an abandoned coal mine from Madrid, New Mexico to bring into the sculpture to be remediated by the saprophytic mushroom Pleutrous ostreatus, or pearl oyster. This waste was laden with heavy metals such as lead, arsenic, and cadmium. Slowly, several oyster mushrooms fruited from these tailings. The interior of the piece was built with layered shelves and included plants and insects to show the range of diversity of the fungal ecosystem as well as point to the necessity of creating a remediation team to not only provide a healthy and diverse habitat, but also allow for series of biochemical processes to ensue within and feed the microbial masses. Within the framework of the sculpture the materials transformed daily.
