Mustard powder lichen

Chrysothrix candelaris

Description:

Chrysothrix candelaris is a bright yellow crustose lichen that doesn't show any reproductive structures like ascocarps. I thought it was a yellow-painted fence when I first saw it. It needs a few conditions to be met for it to thrive such as a dry shaded area and is usually found on old bark of sycamore, alder, oak, willow, beech, and Pinus species.

Habitat:

Spotted on old fence boards under the shade of a spruce tree.

I've seen patches of these around here but nothing this bright. Nice spotting Brian and good to have an ID.

Hmm.. definitely seems relevant to the presence of that tree.

Thank you Tukup and Neil. Haha, your so funny Neil! I often get that headache before I post them!

Mother nature has chosen her own colour, and it's mustard yellow. A good choice. Cool spotting, Brian, and I'll second Tukup - good job identifying it. Whenever I post any fungus spotting, guaranteed the ÏD "headache" is bound to follow :-/

Jaundiced eye Sukanya??? 😊 Good one.

Interesting Brian. I would have thought some kind of mold. Good job identifying it.

Even though not looking at it with a jaundiced eye, I think Colman's mustard will be edged out ...should this arrive on supermarket shelves. Great spotting Brian and what an extraordinarily appropriate name.
