Reproductive systems of the myxomycetes Comatricha laxa and Lamproderma arcyrionema
Clark, Jim; Haskins, Edward F.
Four cultures of the myxomycete Comatricha laxa were isolated from woody cactus detritus collected in Arizona. All four isolates were heterothallic and belonged to a single biological species. However, three of the isolates produced myxamoebal clones which were all of the same mating type, thus displaying a modified heterothallic system in which the diploid plasmodia segregate out only a single mating type in their spores. A single isolate of Lamproderma arcyrionema was also cultured, for the first time, and found to be nonheterothallic.
