Firstly, I understood that Jason knows portuguese: Yes, “Rei Zaca” is the correct expression.
Secondly, it is J-Dar that wants to know details about portuguese habitats: No, I’m not bored today; On the contrary, I’m doing some microscopy … So, you have to wait a bit more, but was already my intention to document with photos the locations I’m used to visit, in addition to the photos that I post in specific observations.

They’re in there

You might have to scroll through a lot of his observations, but zaca does post habitat photos frequently. I’m so jealous. :)

Yeah what’s up with that?

All of Zaca’s photos are of gorgeous museum worthy specimens! I’d love to see some habitat shots of your Portuguese oak woodlands, Zaca, if you are bored today :)

Oops, my comment came way out of order, sorry!

Collection: yes, no way to avoid taking a chunk of the tree. :(

We can’t all be blessed with big, perfect, beautiful specimens

every time we walk out of the door. Some day I hope you see what we’re dealing with in southern California, ha! Count your blessings Rei Zaca. :)

How do you collect something like this that is so continuously attached? Cut into the bark and lift a section out?

The whitish marks on the thallus that are not related with soredia.

Yes, that will be my choice too, Jason,

though the eroded zones are much more developed than I’m used to see here.

Good test for me, too

Does Pertusaria albescens sound right to you, too, zaca?

Come on Zaca
