Epiphytic lichens are used broadly as bioindicators, as they are sessile organisms with slow growth and different species display a wide range of environmental sensitivity. Most studies on epiphytic lichens focus on their use as indicators of the present environmental conditions, but few studies assess the changes that occur over decades. Comparati...

Powdery mildews are the subject of intense research due to their negative impact on agriculture or horticulture. The genetic diversity of these ascomycete fungi has only been surveyed in the last decades to investigate phylogenetic relationships and species boundaries, to propose new taxa, and to assess their biogeographic history. However, many of...

In coastal areas saxicolous lichens follow a gradi-ent which is determined by the distance from the sea. There have been previous gradient studies along a horizontal plane. In our case we wanted to study in a vertical plane so we studied La Falcon-era cliff. We identified 31 species, of which nine are first recordings in Catalonia: Collema aff. eut...
