Gyalideopsis altamirensis

About

Gyalideopsis altamirensis is a species of corticolous (bark-dwelling) crustose lichen in the family Gomphillaceae, first described in 2006 from specimens collected in Costa Rica as part of the Ticolichen biodiversity inventory project. The pale greenish-grey lichen forms thin, shiny crusts on tree bark in montane rainforest environments, particularly in secondary forests dominated by Cecropia trees, and is known only from three locations in Costa Rica. It reproduces through distinctive brown to purplish-brown disc-shaped structures that produce large, colourless spores, and while specialized reproductive structures called hyphophores have not been observed in this species, it shows morphological similarities to several leaf-dwelling relatives as well as to other bark-dwelling species from which it differs primarily in having lighter-coloured fruiting bodies with more prominent margins.
