This distinctively warty lichen is Melanohalea exasperata (with several friends) on a lushly populated oak twig.

It can be tricky to find as it mostly grows high up in the tree canopy - so far I've only enountered it on branches that have recently fallen to the ground.

Lichens change quite dramatically as they dry out. Here is a lichen-covered stick that I 3d-scanned three times over the course of 24hours. Played back as a crude 3d animation in VR.

Melanohalea exasperata

Warty-camouflage lichen

I mean, where to start, right? So much going on here. M. exasperata is a foliose lichen has rounded lobes which are shiny green-brown to red-brown on top, and pale-brown on the bottom. The upper surface is covered in volcano-shaped papillae tipped with white pseudocyphella. It produces lots of bowl-shaped apothecia which have a concolorous, indented disk surrounded in a warty, papillate covered exciple. M. exasperata is rare, and grows on deciduous trees in the northern hemisphere.
