“…Published data of members of Zanclospora suggest a worldwide geographical distribution. Species were recorded from the tropics of Brazil, Brunei, Cuba, India, Ecuador, Ivory Coast, Kenya, Nigeria, Seychelles, Taiwan and Vietnam, but also from the temperate and subtropical climate zones of the Southern and Northern Hemispheres in Japan, New Zealand, South Africa, Spain and the USA [1][2][3][4][5][6][7][8][9][10][11][12][20][21][22][23][24][25][26][27][28]. Almost all published records were from decaying bark and wood, less often from fallen leaves, and were obtained by direct observation on natural substrates.…”

Phylogeny, Global Biogeography and Pleomorphism of Zanclospora

et al. 2021

Zanclospora (Chaetosphaeriaceae) is a neglected, phialidic dematiaceous hyphomycete with striking phenotypic heterogeneity among its species. Little is known about its global biogeography due to its extreme scarcity and lack of records verified by molecular data. Phylogenetic analyses of six nuclear loci, supported by phenotypic data, revealed Zanclospora as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes. Zanclospora is a pleomorphic genus with multiple anamorphic stages, of which phaeostalagmus-like and stanjehughesia-like are newly discovered. The associated teleomorphs were previously classified in Chaetosphaeria. The generic concept is emended, and 17 species are accepted, 12 of which have been verified with DNA sequence data. Zanclospora thrives on decaying plant matter, but it also occurs in soil or as root endophytes. Its global diversity is inferred from metabarcoding data and published records based on field observations. Phylogenies of the environmental ITS1 and ITS2 sequences derived from soil, dead wood and root samples revealed seven and 15 phylotypes. The field records verified by DNA data indicate two main diversity centres in Australasia and Caribbean/Central America. In addition, environmental ITS data have shown that Southeast Asia represents a third hotspot of Zanclospora diversity. Our data confirm that Zanclospora is a rare genus.

“…Saprobic fungi have recently attracted special attention as biological control agents and potential resistance inducers (22) since, like plant pathogenic fungi, they are capable of secreting pectinases, inducing the release of oligogalacturonides and activating the plant defense response. Fungal biodiversity prospecting has been conducted in semiarid areas and various saprobic fungi were identified in the litter of the Caatinga forest in northeastern Brazil (3,6,14,16). Within the framework of the SISBIOTA Program (CNPq/FAPESP), some of these fungi were tested for their ability to control some infectious diseases in various crops.…”

Biocontrol of Sclerotinia sclerotiorum and white mold of soybean using saprobic fungi from semi-arid areas of Northeastern Brazil

et al. 2015

The incidence and the levels of yield loss caused by the white mold of soybean (caused by the fungus Sclerotinia sclerotiorum) have increased in areas of higher altitude at Cerrado and Southern Brazil, causing yield losses of up to 60%. The aim of this study was to select saprobic fungi with the potential to control the white mold of soybean. First, in vitro antagonism screening was carried out to test eight saprobic fungi against S. sclerotiorum. Assessment of S. sclerotiorum mycelial growth was done at four and seven days after its placement on the culture medium. The isolate showing greatest antagonistic effect in all tests/assessments was Barros, D.C.M.; Fonseca, I.C.B; Balbi-Peña, M.I.; Pascholati, S.F.; Peitl, D.C. Biocontrol of Sclerotinia sclerotiorum and white mold of soybean using saprobic fungi from semi-arid areas of Northeastern Brazil. Summa Phytopathologica, v.41, n.4, p.251-255, 2015.Myrothecium sp. An in vivo experiment was conducted in a greenhouse and growth chamber, where plants previously treated with eight saprobic fungi were artificially inoculated with S. sclerotiorum. The fungal culture medium (potato-dextrose) and the commercial resistance inducer acibenzolar-Smethyl were used as controls. In the in vivo tests, severity of the white mold was assessed at 8, 14 and 21 days after inoculation. The highest reduction percentage in the lesion length was observed for the treatment with Myrothecium sp. (70%), which has the greater potential to be used as biocontrol agent of soybean under the conditions of this experiment. ARTIGOSBiocontrol of Sclerotinia sclerotiorum and white mold of soybean using saprobic fungi from semi-arid areas of Northeastern Brazil A incidência e os níveis de dano do mofo branco da soja (causado pelo fungo Sclerotinia sclerotiorum) têm aumentado nas áreas de maior altitude do cerrado e da região sul do Brasil, causando reduções de produtividade de até 60%. O trabalho objetivou selecionar fungos sapróbios com potencial de controle do mofo-branco da soja. Primeiramente, realizou-se teste de antagonismo in vitro onde testaram-se oito espécies de fungos sapróbios em confrontação com S. sclerotiorum. A avaliação do crescimento micelial de S. sclerotiorum foi realizada aos quatro e sete dias após a repicagem. O isolado de maior efeito antagônico em todos os ensaios/avaliações foi Myrothecium sp. RESUMORealizou-se ensaio em casa de vegetação e fitotron onde plantas tratadas com oito fungos sapróbios foram artificialmente inoculadas com S. sclerotiorum. Como controle foram utilizados o meio de cultura dos fungos (batata-dextrose) e o indutor comercial de resistência Acibenzolar-S-metílico. No teste in vivo, a severidade do mofo branco foi avaliada aos 8, 14 e 21 dias após a inoculação. A maior porcentagem de redução do comprimento da lesão foi observada para o tratamento com Myrothecium sp. (70%); o qual apresenta o maior potencial de utilização como biocontrolador de S. sclerotiorum nas condições do experimento. Keywords: biological control, Glycine max, white moldWhit...

“…Its occurrence in Taiwan was also reported (Matsushima 1980). The species has been recorded from many countries, but their identity to the type specimen needs to be confirmed by comparative study on morphology and phylogeny (Hughes and Kendrick 1968;Matsushima , 1980Matsushima , 1989Matsushima , 1993Mercado-Sierra et al 1997;Delgado-Rodriguez et al 2002;Arias et al 2010;Almeida et al 2011;Cruz et al 2014).…”

Chaetosphaeriaceae is one of the largest families in Sordariomycetes that commonly found on decaying leaf, fruit, branch, bark and wood in both terrestrial and submerged environment in nature. This paper reports our research result of diversity, taxonomy and phylogeny of anamorphic Chaetosphaeriaceae in China, which is based on a systematic study with an integrated approach of morphological observation and phylogenetic analysis for a large collection (>1300 herbarium specimens and 1177 living strains). The family Chaetosphaeriaceae is further expanded to accomendate 89 accepted genera, including 22 new genera and 10 newly assigned genera. Most of these genera (except for Chaetosphaeria and several other relatively large genera) are delimitated as monophyletic genera with well-defined diagnostic characters in morphology. The phylogenetic connection of non-phialidic Sporidesmium -like fungi with the family is further confirmed and expanded to 10 different genera. The polyphyletic Codinaea / Dictyochaeta/Tainosphaeria complex is further resolved with a taxonomic framework of 28 monophyletic genera by redelimitation of Codinaea and Dictyochaeta with narrow concept, acceptance of the 16 established genera, and finally introduction of 10 new genera. Chloridium is phylogenetically redefined as monophyletic genus with narrow concept as typified by the type species, a systematic review in both generic and species level is still needed. For biodiversity of chaetosphaeriaceous fungi, a total of 372 species in 76 genera, including 126 new species, 48 new combinations, and 1 new name, are documented. The identification keys are provided for most genera, especially the large genera such as Codinaea , Codinaeella , Stilbochaeta , Cryptophiale , Thozetella , Dinemasporium and Pseudolachnella . In addition, ten known species were excluded from the family and reclassified. One of the future research area for this family should be the systematic revision of several relatively large polyphyletic genera, including Bahusutrabeeja , Ellisembia , Stanjehughesia , Cacumisporium , Chaetosphaeria , Chloridium , Craspedodidymum , Cryptophiale, Cryptophialoidea , Dictyochaetopsis , Minimidochium , and many published species of Codinaea and Dictyochaeta .
