1The numbers of fungi: is the descriptive curve flattening?显示文摘The recent realistic estimate of fungal numbers which used various algorithms was between 2.2 and 3.8 million.There are nearly 100,000 accepted species of Fungi and fungus-like taxa,which is between 2.6 and 4.5%of the estimated species.Several forums such as Botanica Marina series,Fungal Diversity notes,Fungal Biodiversity Profiles,Fungal Systematics and Evolution-New and Interesting Fungi,Mycosphere notes and Fungal Planet have enhanced the introduction of new taxa and nearly 2000 species have been introduced in these publications in the last decade.The need to define a fungal species more accurately has been recognized,but there is much research needed before this can be better clarified.We address the evidence that is needed to estimate the numbers of fungi and address the various advances that have been made towards its understanding.Some genera are barely known,whereas some plant pathogens comprise numerous species complexes and numbers are steadily increasing.In this paper,we examine ten genera as case studies to establish trends in fungal description and introduce new species in each genus.The genera are the ascomycetes Colletotrichum and Pestalotiopsis(with many species or complexes),Atrocalyx,Dothiora,Lignosphaeria,Okeanomyces,Rhamphoriopsis,Thozetella,Thyrostroma(rela-tively poorly studied genera)and the basidiomycete genus Lepiota.We provide examples where knowledge is incomplete or lacking and suggest areas needing further research.These include(1)the need to establish what is a species,(2)the need to establish how host-specific fungi are,not in highly disturbed urban areas,but in pristine or relatively undisturbed forests,and(3)the need to establish if species in different continents,islands,countries or regions are different,or if the same fungi occur worldwide?Finally,we conclude whether we are anywhere near to flattening the curve in new species description.Kevin D.Hyde Rajesh Jeewon Yi-Jyun Chen Chitrabhanu S.Bhunjun Mark S.Calabon Hong-Bo Jiang Chuan-Gen Lin Chada Norphanphoun Phongeun Sysouphanthong Dhandevi Pem Saowaluck Tibpromma Qian Zhang Mingkwan Doilom Ruvishika S.Jayawardena Jian-Kui Liu Sajeewa S.N.Maharachchikumbura Chayanard Phukhamsakda Rungtiwa Phookamsak Abdullah M.Al-Sadi Naritsada Thongklang Yong Wang Yusufjon Gafforov E.B.Gareth Jones Saisamorn Lumyong 2020Fungal Diversity2020,,4:3

10Predicting global numbers of teleomorphic ascomycetes显示文摘Sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi.The global diversity of teleomorphic species in Ascomycota has not been estimated.This paper estimates the species number for sexual ascomycetes based on five different estimation approaches,viz.by numbers of described fungi,by fungus:substrate ratio,by ecological distribution,by meta-DNA barcoding or culture-independent studies and by previous estimates of species in Ascomycota.The assumptions were made with the currently most accepted,“2.2–3.8 million”species estimate and results of previous studies concluding that 90%of the described ascomycetes reproduce sexually.The Catalogue of Life,Species Fungorum and published research were used for data procurement.The average value of teleomorphic species in Ascomycota from all methods is 1.86 million,ranging from 1.37 to 2.56 million.However,only around 83,000 teleomorphic species have been described in Ascomycota and deposited in data repositories.The ratio between described teleomorphic ascomycetes to predicted teleomorphic ascomycetes is 1:22.Therefore,where are the undiscovered teleomorphic ascomycetes?The undescribed species are no doubt to be found in biodiversity hot spots,poorly-studied areas and species complexes.Other poorly studied niches include extremophiles,lichenicolous fungi,human pathogens,marine fungi,and fungicolous fungi.Undescribed species are present in unexamined collections in specimen repositories or incompletely described earlier spe-cies.Nomenclatural issues,such as the use of separate names for teleomorph and anamorphs,synonyms,conspecific names,illegitimate and invalid names also affect the number of described species.Interspecies introgression results in new species,while species numbers are reduced by extinctions.Indunil C.Senanayake Dhandevi Pem Achala R.Rathnayaka Subodini N.Wijesinghe Saowaluck Tibpromma Dhanushka N.Wanasinghe Rungtiwa Phookamsak Nuwan D.Kularathnage Deecksha Gomdola Dulanjalee Harishchandra Lakmali S.Dissanayake Mei-mei Xiang Anusha H.Ekanayaka Eric H.C.McKenzie Kevin D.Hyde Hao-xing Zhang Ning Xie 2022Fungal Diversity2022,,3:1
