crustose lichen

One example of a type of vegetation is a crustose lichen.

The sandstone rocks themselves are lightly covered in crustose lichens.

That scabby stuff on the rock is crustose lichen.

Environmental modifications and the taxonomy of the crustose lichens.

Above 2200 m live only crustose lichens.

Crustose lichen, for instance, made parts of the red plain look as if they were being plated with apple jade.

Crustose lichens.

Cryptothecia is a genus of crustose lichen in the Arthoniaceae family.

Crustose lichens are an additional weathering agent, tending to penetrate and defoliate rock surfaces (Walton, 1985).

Lichen research is carried out on a world-wide collection which is particularly good on European crustose lichens.

Cryptothecia rubrocincta is a crustose lichen, because it grows in the form of a surface crust.

Both nymphs and adults feed primarily on small crustose lichens, but also consume fungi, dead bark and organic debris.

The male paratype from Alert Stack was found amongst crustose lichens, suggesting these may also be fed on by larvae.

Many lichens also grow close to the surface of rocks, tree trunks and other substrata, and are referred to as crustose lichens.

There are a different types of Crustose Lichens including:endolithic, endophloidic and leprose.

J. scotia is a crustose lichen with a varnish-like thallus that grows to a diameter of 1.5 cm.

Most snow-free areas are so steep and subject to frequent avalanches that only crustose lichens and algal formations are sustainable.

Corticolous crustose lichens contribute the greatest number of species to the lichen flora within the NEC.

These factors have influenced the lichen flora of the area which is dominated by crustose lichen species followed by foliose species.

Coccotrema maritimum is a crustose lichen commonly known as volcano lichen, due to the volcano-like appearance of the fruit bodies.

Lichens also sometimes contain structures made from fungal metabolites, for example crustose lichens sometimes have a polysaccharide layer in the cortex.

The thalli of crustose lichens can adhere to the surface of rock and absorb moisture from atmosphere; therefore, these colonize the bare surfaces of rocks first.

Young, smooth-barked hazel stems are colonised by crustose lichens of the Graphidion, including the very rare Graphis alboscripta.

The colouring of this species is very distinctive and the specific name soralia comes from the resemblance of its markings to the vegetative structures on some crustose lichens.

The branches of the needle bushes (Vachellia farnesiana) are particularly rich in coverage with crustose lichen, specially of those species within the Graphidaceae family.
