文摘Yeasts,usually defined as unicellular fungi,occur in various fungal lineages.Hence,they are not a taxonomic unit,but rather represent a fungal lifestyle shared by several unrelated lineages.Although the discovery of new yeast species occurs at an increasing speed,at the current rate it will likely take hundreds of years,if ever,before they will all be documented.Many parts of the earth,including many threatened habitats,remain unsampled for yeasts and many others are only superficially studied.Cold habitats,such as glaciers,are home to a specific community of cold-adapted yeasts,and,hence,there is some urgency to study such environments at locations where they might disappear soon due to anthropogenic climate change.The same is true for yeast communities in various natural forests that are impacted by deforestation and forest conversion.Many countries of the so-called Global South have not been sampled for yeasts,despite their economic promise.However,extensive research activity in Asia,especially China,has yielded many taxonomic novelties.Comparative genomics stud-ies have demonstrated the presence of yeast species with a hybrid origin,many of them isolated from clinical or industrial environments.DNA-metabarcoding studies have demonstrated the prevalence,and in some cases dominance,of yeast species in soils and marine waters worldwide,including some surprising distributions,such as the unexpected and likely common presence of Malassezia yeasts in marine habitats.

文摘Asexually reproducing fungi play a significant role in essential processes in managed and wild ecosystems such as nutrients cycling and multitrophic interactions.A large number of such taxa are among the most notorious plant and animal pathogens.In addition,they have a key role in food production,biotechnology and medicine.Taxa without or rare sexual reproduction are distinguished based on their sporulating structures and conidiomata in traditional morphology-based taxonomy.The number,variation and diversity of asexually reproducing taxa are insufficiently known,even though fungi capable of asexual reproduction may provide an untapped,rich biological resource for future exploitation.Currently,ca.30,000 asexual species belonging to ca.3800 genera have been reported(including 1388 coelomycetous and 2265 hyphomycetous genera).Recent reports(2017–2020)reiterate that the number of asexually producing fungi is higher than the number of frequently sexually-reproducing fungi.With the advent of molecular tools and the abandonment of the dual nomenclature system for pleomorphic fungi,priority criteria were established and revisited in the latest outline of fungi and fungus-like taxa.However,species numbers and taxonomic boundaries of pleomorphic taxa and their synanamorphs or synasexual morphs have yet to be addressed.The number of species of speciose genera(e.g.Alternaria,Aspergillus,Cercospora,Fusarium,Phoma and Pseudocercospora),cryptic species,species of pleomorphic genera,less studied life modes(such as lichenicolous taxa,taxa from extreme environments)and species from biodiversity-rich areas still need evaluation to achieve more reliable estimates of their diversity.This paper discusses the current knowledge on the matter,with diversity estimates,and potential obstacles in several chapters on(1)speciose genera;(2)pleomorphic genera;(3)cryptic species;(4)well-studied but insufficiently resolved taxa,e.g.leaf inhabiting species,marine fungi,(5)less studied life modes,e.g.lichenicolous,rock-inhabiting fungi,insect-associated and yeast-forming taxa and(6)species from biodiversity-rich areas.

文摘Index Fungorum,Species Fungorum and MycoBank are the key fungal nomenclature and taxonomic databases that can be sourced to find taxonomic details concerning fungi,while DNA sequence data can be sourced from the NCBI,EBI and UNITE databases.Nomenclature and ecological data on freshwater fungi can be accessed on http://fungi.life.illinois.edu/,while http://www.marinespecies.org/provides a comprehensive list of names of marine organisms,including information on their synonymy.Previous websites however have little information on marine fungi and their ecology,beside articles that deal with marine fungi,especially those published in the nineteenth and early twentieth centuries may not be accessible to those working in third world countries.To address this problem,a new website www.marinefungi.org was set up and is introduced in this paper.This website provides a search facility to genera of marine fungi,full species descriptions,key to species and illustrations,an up to date classification of all recorded marine fungi which includes all fungal groups(Ascomycota,Basidiomycota,Blastocladiomycota,Chytridiomycota,Mucoromycota and fungus-like organisms e.g.Thraustochytriales),and listing recent publications.Currently,1257 species are listed in the marine fungi website(www.marinefungi.org),in 539 genera,74 orders,168 families,20 classes and five phyla,with new taxa continuing to be described.The website has curators with specialist mycological expertise who help to provide update data on the classification of marine fungi.This article also reviews knowledge of marine fungi covering a wide range of topics:their higher classification,ecology and world distribution,role in energy transfer in the oceans,origin and new chemical structures.An updated classification of marine fungi is also included.We would like to invite all mycologists to contribute to this innovative website.
