A couple of jaunty sea-side lichens having a tussle. I think I've got Xanothoria aureola in yellow and Anaptychia runcinata in brown (it goes a lovely avocado green colour when well hydrated.)

Xanthoria stiligera
Lichen reproduction and dispersal is a big, complicated, tangled-up mystery (like a lot of things about lichens, TBH). We don't quite understand why certain lichens employ one or more reproductive strategies over another, but clearly it has some advantage or that strategy wouldn't still persist. Like some lichens like X. stiligera make asexual, clonal propagules called isidia, which are made to break off and grow into a new lichen. The isidia that X. stiligera produces are relatively large (0.05-0.1 mm thick), and vary from globose to clavate to branching and coralloid in structure. These structures seem difficult to disperse, but maybe are able to persist over a longer period of time and through harsher conditions than other propagule types? I really want to know.

i made this transparent Xanthoria parietina instead of doing my homework. side blog idea? transparent lichen pngs? what do we think.
I collected some (what I think is) Sunburst Lichen (xanthoria sp.) and have attempted to extract the dye. I gathered quite a bit from fallen branches in the yard. Trying the water method first but I know I'll have to get ammonia at some point. Been day dreaming of harvesting "grandpa blackthorn's lichen" since I was a wee girl.

#2474 - Dufourea ligulata - Strap Flame Lichen
Originally described as Physcia ligulata in 1862, transferred to Xanthoria in 1983, Jackelixia in 2009 and finally Dufourea in 2013 after researchers got a look at its genetics.
On top of a stone fence at the B&B in Hāwera - absolutely typical habitat for the species, which grows on coastal rocks.
