Leptogium marcellii

Leptogium marcellii is a species of gelatinous lichen in the family Collemataceae. It was described in 2018 from the South Shetland Islands, Antarctica. It has overlapping lobes with small, flattened lobules (little flap-like outgrowths used for vegetative reproductio), a distinctly hairy underside, and a soft, gelatinous interior that swells when wet. Internally, its fungal threads (hyphae) are arranged in a loose, sponge-like network around the cyanobacteria rather than as neat vertical "columns", a key trait used to separate it from similar Antarctic species. Apothecia, when present, have rims that are ornamented when young and develop lobules with age....read more on Wikipedia.
