Taxonomy

The genus was circumscribed by the Czech lichenologist Antonín Vězda in 1972. [3]

Description

Gyalideopsis species have a thin, crust-like thallus that often forms a delicate, almost film-like layer over the substrate. The surface is usually smooth, only rarely becoming finely warted, and the thallus tends to spread diffusely rather than forming discrete rosettes. Many species produce distinctive hyphophores —small, erect, scale-like outgrowths thought to function in asexual reproduction where pycnidia are absent. The photosynthetic partner is a trebouxioid green alga (i.e. minute, single-celled algae of the genus Trebouxia or similar). [4]

The sexual reproductive structures are apothecia, typically round and red-brown to almost black. When wetted they swell and become somewhat translucent, and they show a raised rim formed by fungal tissue; there is no thalline margin (the thallus does not wrap around the disc ). Internally, both the apothecial rim ( true exciple ) and the spore-bearing layer (hymenium) are built from a loose, net-like mesh of very fine, branching hyphae embedded in a jelly-like matrix. The asci contain two to eight ascospores, range from cylindrical-club-shaped to egg-shaped, and have a thickened tip; their contents stain wine red in the K/I iodine test (potassium hydroxide pretreatment followed by iodine). [4]

The ascospores are colourless and vary from simply cross-walled to densely muriform , meaning they are divided by many transverse and longitudinal septa into a brick-like pattern. Around each spore there is a perispore (an outer coat) that can be thin or relatively thick. No secondary metabolites have been detected by thin-layer chromatography, so there are no known diagnostic lichen substances in this genus. [4]

Species

As of March 2025, Species Fungorum (in the Catalogue of Life) accepts 52 species of Gyalideopsis. [5]
