Dictyonema giganteum

Dictyonema giganteum is a species of lichen-forming fungus in the family Hygrophoraceae. It is a basidiolichen—its fungal partner belongs to the Basidiomycota rather than the more typical Ascomycota. The species was discovered and described in 2014 from specimens collected in the cloud forests of Colombia's eastern Andes. As its name suggests, it forms unusually large, shelf-like lobes that can reach up to 12 cm (4.7 in) across. The lichen is covered with dense white hairs that give it a frosted appearance and is known only from a small area of sub-montane cloud forest in Casanare Department, Colombia....read more on Wikipedia.
