Gyalectidium fantasticum is a species of lichen-forming fungus in the family Gomphillaceae.[1] It is a leaf-dwelling lichen known from widely separated locations in tropical America, including Paraguay and Costa Rica. The species is distinguished by its unusually broad, flat reproductive structures that lie pressed against the thallus surface and are considerably wider than they are long, with a distinctive color pattern that grades from dark grayish-brown at the base to whitish-translucent above.
Gyalectidium fantasticum was described as a new species in 2001 by Lidia Ferraro and Robert Lücking. The type was collected from the Itabo Private Reserve near Colonia Nueva Esperanza (Canendiyu, Paraguay) at an elevation of 260 m (850 ft). In the original account, it was set apart from other members of the genus by its unusually broad, adnate hyphophores (asexual reproductive structures), which are only slightly raised above the thallus surface.[2]
