Xanthoria elegans
The thallus of this lichen is described as foliose, having the aspect of leaves, although the central portions of the thallus may appear nearly crustose. It is small, typically less than 5 cm (2.0 in) wide, with lobes less than 2 mm broad, appressed to loosely appressed. The upper surface is some shade of orange while the lower surface is white, corticate, with short, sparse hapters. The vegetative propagules called soredia and isidia are absent, although apothecia are common. It has been described as possessing swollen, orange-yellow thalli (in streams), compact orange thalli (on boulders) or dark orange-red thalli on the driest rock faces.
This species grows on rock, both calcareous and siliceous, occasionally overgrowing moss or litter or rock. It is often found on exposed to somewhat sheltered sites, often near bird or small mammal droppings.
Recognized by its bright orange or red pigmentation, this species grows on rocks, often near bird or rodent perches. It has a circumpolar and alpine distribution. It was one of the first lichens to be used for the rock-face dating method known as lichenometry.

Thanks again, Mark
Wonderful discussion here Lars :) and beautiful picture actually. They're fabulous.
Ok, I see what you mean. Thanks Lars!
Smith'sZoo, this is the the Elegant Sunburst; specimen in full sun. The degree of yellow/orange is raised by the ammount of sunlight. I think it's closer to your spotting.

Thank you, arlanda! This is it.
No need to scream at me, Alex...save some "!" please.
And yea, exactly, referring to your argumentation, we would all have to look at the whale as a fish - which it is not. Just like for the Lichen being no fungus.
i changed no slime mold!! and i surely know the fact of slime mold are amoebozoas no fungi, the center of nature is "evolution" for me, i understand that veeery well. You can!: take a look at my facebook- startpage ----> galileo/flatt planet!!! Becaue scientstic taxonomy isn't right now, i think the wale is a fish !!! but let it be, thats also my last comment for this discussion!!
Well, I have all my slime molds in "other" due to the fact that they are Amoebozoae, which are officially not counted to fungi any longer - reported that to you weeks ago - and as far as I remember, you changed some after that. Your choice where to categorize it. If any Ranger proofs me wrong, he is free to change my Lichen or Slimemold categorizations - as for me, I keep them where they belong: Into "others" (since there are no subcategories or new scientific kingdoms/classes)...maybe you need to understand that humans are not the center of nature and nature generates new species with a blink of an eye - keeping nature and it's (human) categorization in a steady change. Hundreds of years ago "scientists" didn't even figure this planet to be a ball...anyone claimed this plantet to be flat as a surfboard - have they been right?
first i thought you had written it wrong: but WHERE is 1 slime mold from me categorized as other, i always categorize slime mold as fungi. if there is 1 slime mold spotting not so, then there have to be a ranger sitting on!!
Erm...no need to make myself clear again; so this is my final stand to that issue:
Lichens are varying strongly from the morphology and physiology of fungi - eventhough if the basis was (!) a fungus, with the symbiosis with the algae both species vary from their former morphology and physiology - which makes clearly (!) a new species. And this new species is wether a fungi nor an alga.
try Xanthoria elegans, maybe ...

i will give you the reason, why i categorize aslo slime mold as "category fungi" , This category "fungi" is as good defined as "others", as clive already said: there need to be subclasses!! As long as that not is, I see this particulary "fungi"category as --> Category "MYCOLOGY". <---> where ascomycota,badsidiomycota,yeasts,oomycetes,Zygomycota,Chytridiomycota,Glomeromycota,lichen,mold and slime moulds all get investigated. I allready comment on this 2 weeks ago : ( http://www.projectnoah.org/spottings/861... ). pn isn't for nice picture it is originally for hard data!!
Sorry, no, Alex. You won't convince me - even less since you categorize as well as me Amoebozoa also not to fungi. And Slime molds are closer to fungi than lichens are. Period.
i said wikipedia because it is the most used reference here, namy/all other site says the same, let me see the references to which you referring to the last time (not found back !!?) . standalone species: where will you set the mudskipper and the wale (as in you previous comments) doesn't matter, what's matters is : even as standalone species and possibly not right (for you) : It is legitime agt kingdom: fungi. They put them there because the mainpart/rol of the lichen goes to the fungi (mostly ascomyceten and some basidomyceten) for mycologist (fungi-science) .
Alex, again - i don't give much on the categorization on wikipedia - it is clearly said that lichens are a standalone species that is categorized to fungi just because there is no idea where to put it else. The discussion about how to categorize lichens are still on - the fact that it is counted to fungi doesn't mean it to be correct. And I don't look to it as being correctly categorized.
lichen belong to fungi, it pains me to see them at "others" (which is so well defined !!! ). even if it is a symbiont, take a look at wikipedia, They are categorized as FUNGI. :)
