A rock shield lichen (Xanthoparmelia sp.) on a rock face in meltwater

A wet, flat, round, grey-blue rock shield lichen (Xanthoparmelia sp.) on a black rock face in meltwater.
The lichen is covered with fruiting bodies (apothecia) and surrounded by a few thin, old branches and brown leaves.

The #Tucson botanic gardens is currently hosting a watercolor exhibit called Curious Allies that originated at the NY one. (https://www.nybg.org/event/wonderland-curious-nature/wonderland-curious-nature-programs/asba-curious-allies/). There was a lecture today on the topic of mutualism in nature, so in addition to seeing all the cool art, I learned about lots of neat lichen, fungus, and carnivorous plants. Maybe it will come near you! (https://asba-art.org/ExhibitionCuriousAllies)

The fungi, lichens, and plants featured in this show rely on ingenious mechanisms of symbiosis—sometimes mutual, sometimes parasitic—to get what they…

A special Cladonia lichen, the Rosette Pixie-cup lichen (Cladonia pocillum) on a rock face

The side view of the Rosette Pixie-cup lichen (Cladonia pocillum).
A rosette of large, almost upright leaves (squamules) of a Cladonia lichen grows on moss on a rock face.
The squamules are green-brown on the upper side and white o the underside.
A grey-brown, cup-shaped lichen structure (podetium) grows from these squamules.
Light brown pebbles can be seen inside and on the stem of the podetium.

In dutch lichen is called "korstmos", so I'm considering it a moss here.

You've convinced me! Bringing back extinct lichen is a great way to do proof of concept for bringing back extinct organisms,

Found a nice vitricolous lichen yesterday in New York. I'm assuming it's some sort of rock shield (Xanthoparmelia) but not sure which one. Per Harris (2004) there are 15 different species in the state. #lichen #glass #nature #fungi #algae #inaturalist https://www.inaturalist.org/observations/269613876

The many orange tips of this ground lichen were impossible to miss as I climbed up the trail, as if the lichen was hoping to be noticed. I didn't want to let this organism down, and here we are

The image shows a cluster of small, orange-tipped lichen growing on a dark, slimy base in a forest floor setting. There are also bits of greenery, such as moss, and leaf litter surrounding the mushrooms. It looks like a damp, natural environment typical of places where fungi and lichen thrive.

The Star Rosette lichen (Physcia stellaris) and the Rosette lichen (Physcia millegrana) on a tree bark

Two different leaf lichens of the same genus on a tree bark, the Star Rosette lichen (Physcia stellaris) and the Rosette lichen (Physcia millegrana).
The upper, large and round Star Rosette lichen has grey-blue lobes that are almost completely covered with round, flat fruiting bodies (apothecia).
The apothecia have black discs and white margins.
Directly below this lichen grows the Rosette lichen, which has lighter-coloured lobes and yellowish, powdery soredia* on the edges of the lobes.
*Soredia are small granules of fungal hyphae and algae for the reproduction of the lichen.

Smooth-footed Powderhorn lichen (Cladonia ochrochlora) among mosses

Close-up of an old tree stump overgrown with mosses.
A Smooth-footed Powderhorn lichen (Cladonia ochrochlora) grows in the centre of these mosses.
This lichen consists of upright growing small leaflets (squamules), which are smooth and white on the underside and green on the upper side.
Two upright horn-shaped parts (podetia) grow from these squamules.
The surface of these podetia is partially covered with a light green powder (soredia*).
Here it looks as if the surface of the podetia is damaged, but this is not the case.
This is a particular characteristic of this type of powderhorn lichen.
*Soredia are small granules of fungal hyphae and algae for the reproduction of the lichen.

Another from my Ginko Petrified Forest collection. The orange on this one was just so vibrant. I come back and find this one every time I pass through.

If anyone knows the species of the lichen I post, I'd love to know.
