I took this picture because I liked the forms and textures of these growths on a tree trunk. Here I am totally out of my depth when it comes to ID. Hopefully the mycologists on TN will be able to lend me a hand. Thank you in advance.

Lichen

If the other fungi (such as mushrooms) are nature's recyclers, lichens are nature's pioneers. Lichens find their homes in some of the most barren and inhospitable parts of the world. From there they slowly begin the process of creating a foundation for habitation by others.

Lichens are among the most fascinating organisms on this planet. Their very structure is unique: a symbioses of two organisms -- a fungus and algae -- so complete that they behave and look like an entirely new being. A lichen can literally eat stones, survive severe cold, and remain dormant for long periods without harm.

Lichens rank among the least well known forms of life. Common names, when available, typically apply to the entire genus rather than to indvidual species. Classification of lichens is undergoing change as well. In fact, mycologists now suggest eliminating the Lichens as a Phylum and, instead, reclassifying each invidual lichen according to its fungal component -- mostly Sac Fungi (Ascomycota). Nevertheless, lichens look so different from other fungi that they deserve separate treatment.

Lichens can be divided into three basic forms: crustose, or crust-like; foliose or leaf-like; and fruticoseor stalked.

All lichens are believed to be edible (or at least not poisonous) except for Wolf Moss. Rock-tripe Lichens are even considered a delicacy by the Japanese.

Hi Manyee,
Very nice capture, the colors are cool and POv is nice. Satish.h

What a nice shot you have composed of these lichen formations on an old tree trunk, Manyee!
The purplish BG offers a lovely contrast to the white lichen "flowers", as it were.
TFS.

I like them too, but nevere can take good shot. All my pictures are far away from what they are. Good picture!

Hi ManYee,

This is a nice image. Where in San Mateo did you take it? If it were my image I would tone down the green in upper right corner. I think it may have over-responded to the enhancements you did for the rest of the image. I think you could tone down the glare a little with Highlights and Shadows and sharpen a little more. It is an interesting shot with great textures. It's nice having you identify the plants, fungi and wildlife I grew up with and lived with for decades and didn't know the names of : /

Hi Manyee,
A bit of a late one last night (work not fun!!). Just time for a very quick visit.
Thanks for posting, well worth a big smiley.
