Frozen rock carpet

This is the most prevalent moss I saw on those mossy rocks (from yesterday's post). 

Tiny green moss with frozen tips.

In the shade and along the edges, where the sun had just managed to reach the moss, each little plant carried this fringe of ice crystals on the thread-like tips of the leaves. As it dries, it starts to turn brown, and wears a fringe of white fur.

Sun-warmed moss.

This, I think, is Hoary rock moss, aka Woolly Fringe-moss, Racomitrium lanuginosum. The leaves are up to 3 mm. long, and each ends in a short, clear bristle, which gives it that wooly look.

One moss plant, one pixie-cup lichen,

Zooming in, about half the length of each leaf is green; the rest is that white bristle tip.

Lichens tomorrow.

Estos son los musgos más comunes que cubren las rocas de las fotos que subí ayer.
  1. Un musgo muy pequeño, aquí con las puntas de las hojas congeladas. En la sombra, y a los bordes, donde el sol apenas les había llegado a alumbrar, cada plantita llevaba cristales de hielo en los hilos que forman la punta de cada hojita.
  2. Aquí, ya les calentó el sol. Esto, creo, es el musgo "Lanudo" Racomitrium lanuginosum. Las hojas miden hasta los 3mm. y cada una termina con un pelo semi-transparente, lo que da al conjunto esa apariencia como de lana.
  3. Muy de cerca: una plantita de musgo, una taza de liquen "copa de duende".
Mañana, sigo con los líquenes.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
