Tree Hair

Technically the first two attached spottings are Lichen which are both fungi and plant working together in a symbiotic relationship. The third appears to be a cup fungi of some sorts, where the link at the bottom may help you identify your spotting. As for the last spotting, a search unveiled that it is a member of the Dikarya sub-kingdom which means that it is a fungus.

Thank you so much LuckyLogan! I am very happy to add this to your mission. May I ask which one of my other spotting should add to your mission? I am little confused to identify which one is "mold." How about these attached, or are these fungi group?

Nice find RiekoS. It would be great if you could add this spotting and other slime mold spottings you have to my mission http://www.projectnoah.org/missions/4357...

Thank you very much Mark Ridgway. I was not quite sure if I would post it or not, but I am glad I did. And thanks to KarenL for posting this to "Fun fact"! I got over 400 votes! I am very happy :-)

Beautiful cluster Reiko.

Thank you very much for your comment KathleenMcEachern. I did not know what this was, so I am learning :-)

There are many cool slime molds! this is a pretty one.

Thank you so much Reza Hashemizadeh!

Thank you so much KarenL for the " Fun fact!"
I truly appreciate it.

Awesome !

Fun fact! Slime molds are not fungi but often form fungus-like fruiting bodies. Although many slime molds fruit on wood, they do not actually penetrate the surface but form structures called plasmodia - masses of protoplasm that lack cell walls and have the ability to creep around engulfing bacteria, spores of fungi and plants, protozoa, and
particles of nonliving organic matter.

Thank you so much Leonardo! I thought this was not interesting enough and I was not quite sure if I would post it or not. So, thank you again.

Very, very interesting. Great work!

@chesterbperry: So, I did. Thank you so much for y our help!

Yes Rieko, other is the correct category, "slime mold" is a bit of a misnomer since true mold is a fungus.

Thank you very much for your comment Jemma.

Thank you very much for your help chesterbperry. So, which category shall I use for "mold"? "Other"?

I like the second picture because it puts the organism into perspective .It gives us a clue as to what to look for.

Well it is neither, it is a slime mold.
