Interest in "Labyrinthula" started when it was defined as the cause of the "wasting disease". An epidemic happened in the 1930s in the North American and European coasts, killing over 90% of the seagrass ("Zostera marina") population. The first description of similar symptoms in terrestrial grasses happened in 1995 in California. The target organism is turfgrass and the pathogen identified by the Koch's postulates is "L. terrestris". Both seagrass and turfgrass can be infected by organisms of the "Labyrinthula" genera, but from different species, one marine and one terrestrial one, respectively.
