Description
Tomasellia lichen is a group of lichens that form small, dark patches on tree bark. They have a unique structure where fungal threads grow into algal cells, forming a symbiotic relationship. These lichens are often overlooked due to their inconspicuous appearance. Some species in this group have specialized structures called perithecia that help in spore dispersal.
