Saccomorpha lobata Hook, Campbell, Radtke et Golubić, 2024

Key feature (diagnosis): S. lobata represents a different form of proliferation in which the sporangial cavity widens laterally, forming two to several horizontal lobes (GOLUBIC et al. 1984a, figs. 3D, E). This type of expansion often extends to a point of crowding, forming a layer of expanding sporangial cavities, often occupying a large area. Interconnecting hyphal tunnels are not different from those in S. clava.
