Gyrocollema is a small genus of cyanolichens placed in the family Porocyphaceae. A 2024 multilocus study of the class Lichinomycetes emended Porocyphaceae and provisionally included Gyrocollema in that family; earlier sources classified it in Lichinaceae. Species are tiny, dark lichens associated with cyanobacteria and typically occur on rock in well-lit sites that are intermittently wet. Two names are widely cited, though the circumscription and family placement remain tentative pending additional sampling.[1]
The genus, which was originally erected by the Finnish lichenologist Edvard August Vainio in 1929,[2] comprises two species:[3]
- Gyrocollema rupestrinum (Zahlbr.) Henssen (1986)
- Gyrocollema scyphuliferum Vain. (1929)
