Graphis alboscripta

White Script Lichen (Graphis alboscripta), known only from a few Scottish west coast hazelwoods.
 

Graphis scripta

Common Script Lichen (Graphis scripta) on the left and Pyrenula occidentalis on the right.  These are crustose lichens of the smooth bark found on young hazel stems before they become overgrown with mosses and liverworts.
 

Pyrenula laevigata

Pyrenula laevigata, another lichen of smooth young hazel stems, its edges marked by rows of small black dots.
 

Collema fasciculare

Octopus Suckers (Collema fasciculare), a jelly lichen that swells up when wet, as here.
 

Leptogium burgessii

Frilly-fruited Jelly Lichen (Leptogium burgessii), one of the commonest and most easily-recognised jelly lichens.
 

Leptogium hibernicum

Leptogium hibernicum, a rare oceanic jelly lichen.
 

Leptogium coralloideum

Another rare jelly lichen, Leptogium coralloideum.
 

Fuscopannaria sampaiana

Fuscopannaria sampaiana.  Smells of Juicy Fruit chewing gum.
 

Parmeliella triptophylla

Parmeliella triptophylla.  The orange blobs are fruitbodies, which are unusual in this species.
 

Parmotrema crinitum

Another species that rarely fruits is Desperate Dan (Parmotrema crinitum) which was abundant on hazel in the wood, and here has a fruit surrounded by the stubble which gives the lichen its English name.
 

Pseudocyphellaira norvegica

Norwegian Specklebelly (Pseudocyphellaira norvegica)
 

Peltigera praetextata

Rough Dog Lichen (Peltigera praetextata)
 

Nephroma laevigatum

Nephroma laevigatum


Lobaria amplissima

Lobaria amplissima.  This lichen contains both a green alga (in the smooth green areas) and a cyanobacterium (in the bushy brown growths).
 

Polyporus brumalis

Among the few fungi seen were Winter Polypore (Polyporus brumalis) on a partly buried hazel stick...
 

Tremella foliacea

...and Leafy Brain Fungus (Tremella foliacea) on old standing hazel bark.
 

Rhytidiadelphus triquetrus

Finally, LNHG's Species of the Month, Teddy-bear Moss (Rhytidiadelphus triquetrus), was abundant on the woodland floor.
