description Peccania coralloides Overview
Peccania coralloides is a small lichen in the genus Peccania, a group of lichens associated with cyanobacteria as their photosynthetic partner. It is recognizable by its dark, coralloid growth form, in which short branches or lobes form a compact cushion-like thallus. The species is associated with dry, exposed habitats and is particularly linked with calcareous ground or rock, where its dark thallus contrasts with the substrate.
help Peccania coralloides FAQ
What kind of organism is Peccania coralloides?
Peccania coralloides is a lichen-forming fungus in the genus Peccania and family Phylliscaceae. It is a cyanolichen because its photosynthetic partner is a cyanobacterium.
What does Peccania coralloides look like?
It forms a dark, compact, coralloid cushion made of short branches or lobes. Descriptions give the thallus as roughly 2 centimeters wide and up to about 1.5 centimeters tall.
Where does Peccania coralloides grow?
Peccania species are mainly rock-dwelling lichens found in bright, relatively drought-prone microhabitats. Peccania coralloides can occur on both acidic and calcareous rock substrates.
Why are cyanobacteria important to Peccania coralloides?
The cyanobacteria act as the photosynthetic partner in the lichen association. They provide organic compounds made through photosynthesis while the fungal body supplies structure and protection.
