(sclerocarp) is the predominantly sclerenchymatous layer that includes and surrounds the locular envelope(s), uniting them into a common structure known as the "stone." This tissue, composed mainly of tortuous tracts of fibers, but sometimes also of brachyselereids, forms the main part of the septa as well as the external wall of the stone.
