Cladonia furcata (NL: Gevorkt heidestaartje / EN: Cladonia furcata / DE: Vielgestaltige Becherflechte / FR: Cladonia furcata) Like other lichens in the genus Cladonia, the fruiting body of C. furcata is made of a flattened primary thallus and a secondary upright stalk that forms the secondary thallus. The secondary thallus – the podetium – is extensively branched, and may reach up to 10 centimetres tall. The podetia ranges in color from grayish or pale green to brown. The axil, the inner junction of a branchlet with a branch or with another branchlet, is open, with inrolled branches, and frequently with a longitudinal groove that extends down the podetium from the axil. The fertile (reproductive) branches of this lichen are more or less flattened, and often grooved. C. furcata does not have the vegetative reproductive structures soredia and isidia, but instead has apothecia—cup-like ascocarps that contain asci on which ascospores are borne. The apothecia are brown, small, and borne at the end of the branches
