Nose to the ground

 Two mosses, two lichens:

On top of a rock

The mosses are: the Juniper haircap moss (Polytrichum juniperinum), the little spiky "trees" with red stems and their sporophytes, tall, orange spore cases; and the Roadside rock moss, (Racomitrium canescens), with white hairy tips.

The tall(ish) (1 cm.) lichens are Cladonia sp., aka cup lichens. I don't know what that little brown lichen on the right is; I can tell it's a lichen by the apothecia, the dark dots on the tips.

Con la cara en el suelo: dos musgos, dos líquenes.

Los musgos son el musgo birrete, el que parece un arbolito, y un musgo lanudo (Racomitrium canescens). Los líquenes son del género Cladonia; los grandes (aunque solo miden como 1 cm. de alto) son de los llamados "líquenes taza). No pude identificar el pequeño liquen a la derecha.

Goblets and towers

This is a pixie cup lichen.

Cladonia sp., possibly C. gracilis.

Cup lichen growing with mosses. The flattish "leaves", called thalli, are another stage of the same lichen.

Thalli of the Cladonias are composed of two parts – the squamulose primary thallus, developed on the substratum, and the secondary thallus consisting of erect podetia - pointed or cup-forming outgrows, occuring on the upper surface of the primary thallus. (Lichens in the Pieniny)

And I've found a match for the towering cup lichen that I posted a few days ago.

Cladonia verticillata.

And, following a comment on that day, I'm renaming it for my private memory bank as the "Dr. Seuss lichen".

See what I mean? Image from The Architecture of Dr. Seuss.

Lichen found here.
