Mosses, Lichens, Liverworts etc: under-recorded groups

[Robert]

Hypogymnia species, most likely heterophylla.  A foliose species found growing on Pinus jeffreyi, Gerle Creek, El Dorado County, California.



Umbillicaria hyerborea. A foliose species, on metamorphic rock, Gerle Creek, El Dorado County, California. The same species can be found on the same metamorphic rock at Loon Lake, a bit higher up the mountain.



Rhizocarpon species, most likely R. lecanorinum (convex, curved areoles that partially surround the black apothecia). Metamorphic rock, Gerle Creek, El Dorado County, California. Also seen on the same metamorphic rock at Loon Lake.

A good way to spend my birthday.

Happy birthday, Robert!

[Maggi Young]

Yes!  Many happy returns of the day, dear Robert!!

[Robert]

Ralph, Maggi,

Thank you!     

[David Nicholson]

Happy Birthday from me too Robert.

[David Lyttle]

Here is a landscape in miniature mosses and lichens on a rock outcrop in my garden. I have been trying out a new macro lens. These resized jpegs are not as sharp as the originals.

[Maggi Young]

Fascinating - truly a landscape in miniature!

The air in our area is still too polluted for many lichen species. I wish I had a garden like David.

[Leucogenes]

I wished this also... in every regard. What for spectacular photos. Brilliantly.

Some mosses on the local patch. First is Cryphaea heteromalla. Second is Dicranoweisia cirrata. Third is Plagiothecium undulatum and fourth is Sphagnum squarrosum.

[ian mcdonald]

A tiny liverwort. The "large" frond is less than 5mm long. Lophocolea bidentata.

[ian mcdonald]

Thuidium tamariscinum, found today.

[Gabriela]

Thuidium tamariscinum, found today.

How delicate this Thuidium Ian. Admiring mosses on snowless periods is all one can do here in the winter. I got a bit lazy with posting so a few images taken in mid January, if I remember well.
Except Rhodobryum, I am not very sure about the other names
Rhodobryum ontariense


Neckera (complanata maybe)


Plagiothecium


A Thuidium maybe

[ Specified attachment is not available ]Hello,

I organize a botanical outing in the dunes (Pas de Calais France) in June.
can anyone tell me this beautiful licken?
high of 20 to 30 cm. it is present in some hollow dunes.
sometimes it grows into a ball (10 to 20 cm) in diameter and rolls with the wind: an astonishing landscape with a small sound of rolling licken balls ...

[ian mcdonald]

Hello Veronique, lichens are a difficult group to identify, especially for a novice like me. Your lichen looks like a Cladonia species. Those that grow on sand dunes include Cladonia furcata and C. rangiformis. There are others which look similar. I found a paper on the internet by Raphael Jun and Francoise Roze, "Monitoring Bryophytes and Lichen Dynamics in Sand Dunes: example on the French Atlantic Coast."  email raphael.jun@univ-rennes1.fr  Maybe if you email Raphael he may be able to help. The paper is written as an academic study and may be less understood by ordinary people? At least it gives the names of lichens found on dunes during the study.
