Coral Slime

Ceratiomyxa fruticulosa

Slime moulds require damp and humid conditions for their growth and mobility. The moving phase of a slime mould, referred to as plasmodium, is predominantly composed of water and will rapidly dehydrate and perish if humidity decreases. Active slime moulds are seldom seen during dry spells. In excessively dry conditions, some enter a dormant state by developing a hardened, dried structure known as a sclerotium. This enables them to endure extended periods of drought until moisture returns. Their spores can survive for many years in extreme dry environments until rainfall occurs, prompting new growth. Following September's rain plasmodium appeared on logs. An identification cannot be made at the plasmodial stage and a return visit was necessary to determine the species.
