Evidence for the existence of an intramycelial morphogenetic factor controlling the development of coremia of Doratomyces purpureofuscus

Abstract

Development of excised coremia of Doratomyces purpureofuscus (Fries) Morton and Smith requires the presence of living mycelium at the coremium base. Relations between the vegetative hyphae and the synnema are established by means of anastomosis. Coremial development is controlled by an intramycelial factor which is one or several small thermostable molecules.
