Two lichenicolous fungi, one growing on the thallus of in the United Kingdom (Scotland) and the other in apothecia of and in northwestern North America (Alaska and British Columbia) and northeast Asia (Russian Far East, Khabarovsk Krai), show similarities to the species originally described as (later transferred to s. lat and ) from a s. lat. species in Central America. Critical morphological comparison showed that, despite the superficial resemblance between Alaskan, Canadian, Russian, and Scottish collections and the holotype of , they can be distinguished by detailed microscopic analyses. Using three molecular markers, sequences of the nuc 18S, 28S, and internal transcribed spacer (ITS) rDNA regions of the recent Scottish and Alaskan collections were obtained. Phylogenetic analyses confirmed separation of the species and revealed them as a new lineage in Pleosporales, for which the new generic name is introduced for the three species: , sp. nov., , comb. nov. (syn. ), and , sp. nov.

Article Synopsis
- The study describes numerous new species of fungi discovered across various environments, including leaf spots, dead insects, soil, and wood from diverse locations around the world.
- The fungi were isolated from multiple substrates, such as decaying organic matter, living plants, and even specific habitats like semi-desert montane areas and mixed forests.
- Morphological traits and genetic analysis through DNA barcoding confirm the classification and distinct characteristics of these fungal species.

Over the decades our understanding of lichens has shifted to the fact that they are multiorganismic, symbiotic microecosystems, with their complex interactions coming to the fore due to recent advances in microbiomics. Here, we present a mutualistic-parasitic continuum dynamics scenario between an orange lichen and a lichenicolous fungus from the Atacama Desert leading to the decay of the lichen's photobiont and leaving behind a black lichen thallus. Based on isolation, sequencing, and ecophysiological approaches including metabolic screenings of the symbionts, we depict consequences upon infection with the lichenicolous fungus.

Acrospermales represent one of the least studied lineages of Dothideomycetes and are characterized by diverse ecological strategies, including saprotrophic, epiphytic, fungicolous, lichenicolous, and bryophilous lifestyles. The order is composed of two teleomorphic genera, and , and five anamorphic genera of unclear relationships. The objectives of the study were to establish the phylogenetic position of species collected from lichens in the tropical forest of Bolivia and to infer the evolution of the lichenicolous lifestyle in Acrospermales.
