Resumen del Libro
The volume presents a detailed and illustrated (many high quality microcraphs and drawings) study of lichenicolous fungi collected in Isla Navarino (S Chile) and surroundings has resulted in 696 parasited lichen samples, representing 240 taxa of lichenicolous fungi. In this paper 189 species are reported. Six new genera are described: Atronectria gen. nov., similar to Pronectria but with brown, K+ blackish green ascomata, Macrographa gen. nov., with large ascomata and three septate spores of unknown affinities, Pseudostigmidium gen. nov., related to Stigmidium, but generally with I+ red hymenium and 3-septate spores, with five species living on Pseudocyphellaria and Nephroma, Sarcoexcipula gen. nov. of thick and complex perithecial wall and large and septate ascospores, Umbilithecium gen. nov., Arthonia similar genus with diferent hymenial structure and simples spores and Umushamyces gen. nov. similar in habitus to Arthonia but with Biatora or Bacidia-type asci. sp. nov. on Nephroma antarcticum, Merismatium coccotremicola sp. nov. on Coccotrema cucurbitula and perhaps Cladonia, Microsphaeropsis lichenicola sp. nov. on Pannaria and Hypotrachyna, Minutoexcipula beaglei sp. nov. on Lecanora sp. (sterile), Muellerella antarctica sp. nov. on Hypogymnia antarctica and Pannoparmelia, Nanostictis nephromatis sp. nov. on Nephroma antarcticum, Nectriopsis silvaustralis sp. nov. on Pseudocyphellaria vaccina, Neobarya darwiniana sp. nov. on Nephroma antarcticum, Niesslia yaganae sp. nov. on Nephroma antarcticum, Odontotrema navarinoi sp. nov. probably on a terricolous lichen: Micarea magellanica, Phaeosporobolus minutus sp. nov. on Coccotrema and Pertusaria, Phoma rozziana sp. nov. on Pseudocyphellaria guillemini, Plectocarpon gayanum sp. nov. on cf. Siphula, Polycoccum longisporum sp. nov. on Pseudocyphellaria freycinetii, Ph. guilleminii, Nephroma antarcticum and Pannaria sp., Pronectria fragmospora sp. nov. on Usnea, Pronectria invisibilis sp. nov. on Nephroma antarcticum,…
