Contribution to the Study of Lichenicolous Fungi from Northwest Iberian Peninsula (León and Lugo Provinces).

We have found 117 taxa of lichenicolous fungi in the studied area. In this paper, we describe five taxa: on , on , on , on and ssp. on .

Floristic Similarities between the Lichen Flora of Both Sides of the Drake Passage: A Biogeographical Approach.

This paper analyses the lichen flora of Navarino Island (Tierra del Fuego, Cape Horn Region, Chile), identifying species shared with the South Shetland Islands (Antarctic Peninsula). In this common flora, species are grouped by their biogeographic origin (Antarctic-subantarctic endemic, austral, bipolar, and cosmopolitan), their habitat on Navarino Island (coastal, forest, and alpine), their morphotype (crustaceous, foliaceous, fruticulose, and cladonioid), and the substrate from which they were collected (epiphytic, terricolous and humicolous, and saxicolous). A total of 124 species have been recognised as common on both sides of the Drake Passage, predominantly bipolar, crustaceous, and saxicolous species, and with an alpine distribution on Navarino Island.

A new genus, , and a novel nutritional mode revealed in the family Malmideaceae (Lecanoromycetes, Ascomycota).

Lichen-inhabiting fungi are highly specialized mycoparasites, commensals or rarely saprotrophs, that are common components of almost every ecosystem, where they develop obligate associations with lichens. Their relevance, however, contrasts with the relatively small number of these fungi described so far. Recent estimates and ongoing studies indicate that a significant fraction of their diversity remains undiscovered and may be expected in tropical regions, in particular in hyperdiverse fog-exposed montane forests.
