Dear Kaveh, these are not fongi. These are some plant-like creatures classified as hepatica (in persian:Jegar vash ha). Liverworts are a division of plants commonly called hepatics, Marchantiophyta or liverworts. They are typically small plants that are often overlooked. They frequently have the appearance of small irregular leaf-like plaques, often covering large areas of the ground but they may also occur on rocks, trees or any other reasonably firm substrate. They can also take on a form very much like flattened mosses. They most often occur in damp locations and are typically found in moderate to deep shade. Some species can be a nuisance in shady green-houses. They do not have flowers or seeds.You can find more information here!
Excuse me!
