Pyrenothrix
Sign in to savePyrenothrix is a small genus of lichen-forming fungi in the family Pyrenotrichaceae. It comprises two species of filamentous lichens, which are organisms formed by a symbiotic relationship between fungi and photosynthetic partners. The genus is characterized by its unique structure, featuring densely arranged filaments composed of cyanobacteria (blue-green algae) wrapped in fungal threads. Pyrenothrix species form dark greyish-brown growths on various surfaces, with one species found on tree bark and the other on leaves in tropical forests. The genus was circumscribed in 1917 by American scien

Pyrenothrix is a small genus of lichen-forming fungi in the family Pyrenotrichaceae. It comprises two species of filamentous lichens, which are organisms formed by a symbiotic relationship between fungi and photosynthetic partners. The genus is characterized by its unique structure, featuring densely arranged filaments composed of cyanobacteria (blue-green algae) wrapped in fungal threads. Pyrenothrix species form dark greyish-brown growths on various surfaces, with one species found on tree bark and the other on leaves in tropical forests. The genus was circumscribed in 1917 by American scientist Lincoln Ware Riddle, based on specimens collected in Florida. Pyrenothrix is distinguished from other lichens by its intricate cellular structure and reproductive features, including specialized spore-producing structures.
