Green smears

In the dark of the little museum woods, lichens on the lower trunks shine out a pale, ghostly green.

Lichen on a tree on the very edge of the woods, where the light was better.

Lichen and moss.

I collected a few pieces of loose bark and brought it home for a better look, under the microscope.

This is Cladonia. The white blobs at the edges of the leafy structures (squamules) are asexual reproductive structures.

A closer look.

And these are the sexual fruiting bodies. The red spots on top are apothecia, containing fungal spores.

En la oscuridad del bosquecito del museo, los líquenes se destacan por su color verde claro, fantasmal.

Fotos:
  1. Liquen en un tronco al borde del bosque, donde la luz está mejor.
  2. Liquen y musgos más adentro del bosque.
  3. Recogí algunos pedazos de corteza que estaban flojos y los traje a casa para verlos bajo el microscopio. Estos líquenes son del género Cladonia. Aquí, las bolitas blancas a los bordes de los talos, (escamas) son estructuras reproductivas asexuales.
  4. Mirando más de cerca.
  5. Y estos son los cuerpos reproductivos sexuales. Las partes rojas son apotecios, y contienen esporas del hongo que forma parte del liquen..

  1. Neat, I wouldn't have guessed Cladonia until you got closer.

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!
