You already know the image above is Lichen. But perhaps someone will ask, why was lichen submitted as a post to the community of fungi lovers? My reason is that the organisms that look like in the picture above and some of the other pictures below, would not be formed like that, if two organisms did not live together (a complex organism) in a symbiotic relationship mutualism, i.e. the fungus as mycobiont with photosynthetic partners. : green algae or cyanobacteria. Fungi benefit from carbohydrates produced by algae or cyanobacteria through photosynthesis, while the fungal partners with their filaments protect the algae by retaining water, collecting moisture, so that it can provide a larger capture area for mineral nutrients (Wikipedia). So, these pictures are about living together in a symbiotic relationship, about a partnership that allows Foliose lichen to live in a very diverse climate.
When these organisms cling to plants, it seems like they live as parasites, but that's not the case, Lichen only uses plants as substrates (Wikipedia).
But in order not to disappoint the fungus lovers, I have also hunted several fungi:
Coral fungus
Yes, it does look a bit like an aquatic coral. But it has several other names including spaghetti mushroom. The family name of the fungus is Clavariaceae, and here are pictures of the Mucronella species.
Pictures of Foliose lichen and Mucronella I took from the same location, here:
Nameko
A fleshy fungus that is often found living on wood, the genus Pholiota, and this one appears to be the nameko or Pholiota microspora.
And lastly, Gerigit
Gerigit is the name in Indonesia for mushrooms which is a unique culinary there. Scientifically it is called Schizophyllum commune.
