ResumoSerpula lacrimans can produce under certain conditions surface mycelium which grows from discrete points on and at a markedly faster rate than the parent mycelium. The difference in growth rates is maintained after subculturing on to fresh medium of the same composition. The two types of mycelia differ in pigment production and response to staling conditions. Mycelia with or without clamp connexions exhibit the phenomenon. It appears to be different from true sectoring, since the mycelium undergoes some differentiation but not apparently genetic change. The phenomenon is termed point growth and is similar to flushing and to strand formation; all are stimulated by a change to less favourable growth conditions.
