Abstract and Figures

During preparation of an inventory of dematiaceous hyphomycetes from dead plant material in six areas of extreme biological importance of Caatinga biome, some species of Dictyochaeta were found. Dictyochaeta caatingae and D. intermedia are proposed as new species. Dictyochaeta britannica, D. microcylindrospora, D. obesispora, and D. setosa are new records to the American continent, while D. heteroderae is new to the neotropics and D. triseptata is new to Brazil. These species are described, discussed and illustrated. A key to known species collected in Brazil is provided.

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 .

The genus Codinaea is a phialidic, dematiaceous hyphomycete known for its intriguing morphology and turbulent taxonomic history. This polyphasic study represents a new, comprehensive view on the taxonomy, systematics, and biogeography of Codinaea and its relatives. Phylogenetic analyses of three nuclear loci confirmed that Codinaea is polyphyletic. The generic concept was emended; it includes four morphotypes that contribute to its morphological complexity. Ancestral inference showed that the evolution of some traits is correlated and that these traits previously used to delimit taxa at the generic level occur in species that were shown to be congeneric. Five lineages of Codinaea-like fungi were recognized and introduced as new genera: Codinaeella, Nimesporella, Stilbochaeta, Tainosphaeriella, and Xyladelphia. Dual DNA barcoding facilitated identification at the species level. Codinaea and its segregates thrive on decaying plants, rarely occurring as endophytes or plant pathogens. Environmental ITS sequences indicate that they are common in bulk soil. The geographic distribution found using GlobalFungi database was consistent with known data. Most species are distributed in either the Holarctic realm or tropical geographic regions. The ancestral climatic zone was temperate, followed by transitions to the tropics; these fungi evolved primarily in Eurasia and Americas, with subsequent transitions to Africa and Australasia.

Delimitation and phylogeny of Dictyochaeta, and introduction of Achrochaeta and Tubulicolla, genera nova
Article
Dictyochaeta (Chaetosphaeriaceae) is a phialidic dematiaceous hyphomycete with teleomorphs classified in Chaetosphaeria. It is associated with significant variability of asexual morphological traits, which led to its broad delimitation. In the present study, six loci: nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode), nuc 18S rDNA (18S), nuc 28S rDNA (28S), DNA-directed RNA polymerase II second largest subunit gene (RPB2), translation elongation factor 1-α (TEF1-α), and β-tubulin (TUB2), along with comparative morphological and cultivation studies, are used to reevaluate the concept of Dictyochaeta and establish species boundaries. Based on revised species, morphological characteristics of conidia (shape, septation, absence or presence of setulae), collarettes (shape), and setae (presence or absence) and an extension of the conidiogenous cell proved to be important at the generic level. The dual DNA barcoding using ITS and TEF1-α, together with TUB2, facilitated accurate identification of Dictyochaeta species. Thirteen species are accepted, of which seven are characterized in this study; an identification key is provided. It was revealed that D. fuegiana, the type species, is a complex of three distinct species including D. querna and the newly described D. stratosa. Besides, a new species, D. detriticola, and two new combinations, D. callimorpha and D. montana, are proposed. An epitype of D. montana is selected. Dictyochaeta includes saprobes on decaying wood, bark, woody fruits, and fallen leaves. Dictyochaeta is shown to be distantly related to the morphologically similar Codinaea, which is resolved as paraphyletic. Chaetosphaeria talbotii with a Dictyochaeta anamorph represents a novel lineage in the Chaetosphaeriaceae; it is segregated from Dictyochaeta, and a new genus Achrochaeta is proposed. Multigene phylogenetic analysis revealed that D. cylindrospora belongs to the Vermiculariopsiellales, and a new genus Tubulicolla is introduced.

Communities of Fungi in Black Cherry Stumps and Effects of Herbicide
Article
Full-text available
  • Aug 2020
So far, there have been no studies on fungal communities in Prunus serotina (black cherry) wood. Our objectives were to characterize fungal communities from P. serotina wood and to evaluate effects of glyphosate (Glifocyd 360 SL) used on P. serotina stumps on abundance, species richness and diversity of those communities. In August 2016, in the Podanin Forest District, stumps of black cherry trees left after felling were treated with the herbicide. Control stumps were treated with water. Wood discs were cut from the surface of the stumps in May and July–August 2017. Eight treatment combinations (2 herbicide treatments × 2 disc sizes × 2 sample times) were tested. Sub-samples were pooled and ground in an acryogenic mill. Environmental DNA was extracted with a Plant Genomic DNA Purification Kit. The ITS1, 5.8S rDNA region was used to identify fungal species, using primers ITS1FI2 5′-GAACCWGCGGARGGATCA-3′ and 5.8S 5′-CGCTGCGTT CTTCATCG-3′. The amplicons were sequenced using the Illumina system. The results were subjected to bioinformatic analysis. Sequences were compared with reference sequences from the NCBI database using the BLASTn 2.8.0 algorithm. Abundance of fungi was defined as the number of Operational Taxonomic Units (OTUs), and diversity as the number of species in a sample. Differences between the number of OTUs and taxa were analyzed using the chi-squared test (χ2). Diversity in microbial communities was compared using diversity indices. A total of 54,644 OTUs were obtained. Culturable fungi produced 49,808 OTUs (91.15%), fungi not known from culture had 2571 OTUs (4.70%), non-fungal organisms had 1333 (2.44%) and organisms with no reference sequence in NCBI, 934 OTUs (1.71%). The total number of taxa ranged from 120 to 319. Fungi in stump wood were significantly more abundant in July–August than in May, in stumps > 5 cm diameter than in stumps < 5 cm diameter, in glyphosate-treated than in untreated stumps when sampled in May, and in untreated than in glyphosate-treated stumps when sampled in July–August. Species richness was significantly greater in July–August than in May, and in stumps > 5 cm diameter than in stumps < 5 cm diameter, either treated or untreated, depending on size. Herbicides can therefore affect the abundance and diversity of fungal communities in deciduous tree wood. The greater frequency of Ascomycota in herbicide-treated than in untreated stumps indicates their greater tolerance of glyphosate.

Anamorphic chaetosphaeriaceous fungi from China
Article
Full-text available
  • Sep 2022
Chaetosphaeriaceae is one of the largest families in Sordariomycetes with its members 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 1100 living strains). The family Chaetosphaeriaceae is expanded to accommodate 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 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 narrower concept, acceptance of the 16 established genera, and finally introduction of 10 new genera. Chloridium is phylogenetically redefined as monophyletic genus with narrower concept as typified by the type species, but a systematic review in both generic and species level is still needed. For biodiversity of chaetosphaeriaceous fungi, a total of 369 species in 76 genera, including 119 new species, 47 new combinations, and one new name, are documented. The identification keys are provided for most genera, especially the large genera such as Codinaea s. str., Codinaeella , Stilbochaeta , Cryptophiale , Thozetella , Dinemasporium and Pseudolachnella . In addition, ten known species were excluded from the family and reclassified. Systematic revision of several relatively large polyphyletic genera should be conducted in future studies, including Bahusutrabeeja , Ellisembia , Stanjehughesia , Cacumisporium , Chaetosphaeria , Chloridium , Craspedodidymum , Cryptophiale , Cryptophialoidea , Dictyochaetopsis , Minimidochium , and many published species of Codinaea and Dictyochaeta .

Freshwater fungi in the Amazon as a potential source of antimicrobials
Chapter
  • Jun 2022
Little is known about aquatic mycobiota present in the Amazon, but it is estimated that there are several fungi capable of producing compounds with antimicrobial activity. This review attempts to discuss the diversity of fungi in freshwater environments, especially in the Amazon and review the potential of aquatic fungi to produce compounds with antimicrobial activity. The emergence of drug-resistant pathogenic strains, especially in hospital settings, has become a major public health problem since antibiotics used to treat infections caused by these microorganisms lose their microbicidal action. Therefore, it is emphasised that antibiotics of microbial origin are an essential alternative for controlling these pathogens. For this, a bibliographic survey was carried out on the existing literature from sources such as Pubmed, Researchgate, Science Direct, Google Scholar, and Scielo, using the descriptors “fungal freshwater, fungal biodiversity, and fungal antimicrobial”. This review provides information on the diversity of the Amazon, the types of regional hydrography, the diversity of aquatic fungi, and the production of antimicrobials by aquatic fungi. The potential for discovering new antimicrobial compounds in the Amazon exists; however, this potential is limited by the low number of specialists dedicated to this field.

  • Sep 2020
This paper reviews and determines the fungi growing on seeds and fruits of wild plants in various habitats. Such fungi colonise a wide range of substrates with most reported from cones, cupules, and leguminous pods that are high in cellulose and lignin content. There are 1348 fungal species (belonging to 230 families and 609 genera) reported from wild seeds and fruits in 84 countries, listed in this paper. Of these, 300 fungi were described from wild seeds and fruit substrates. Members of the Fabaceae support the highest number of taxa, namely 19% of the novel wild fruit fungi. Twenty-eight genera, including 5 fossil fungal genera have been described from wild seeds and fruits: Agarwalomyces, Amorocoelophoma, Anisogenispora, Archephoma, Centrolepidosporium, Cylindroaseptospora, Cylindromyces, Davidhawksworthia, Delonicicola, Discotubeufia, Glaxoa, Kionocephala, Leucaenicola, Naranus, Neolindgomyces, Pleohelicoon, Quercicola, Remotididymella, Repetoblastiella, Restilago, Soloacrosporiella, Strobiloscypha and Tainosphaeria. Archephoma, Meniscoideisporites, Palaeodiplodites, Palaeopericonia and Xylohyphites are the new fossil fungal genera. Fungal asexual morphs predominate on wild seeds and fruits rather than the sexual morphs. The dominant fungal genera on wild seeds and fruits include Alternaria, Aspergillus, Candida, Chaetomium, Cladosporium, Colletotrichum, Curvularia, Diaporthe, Drechslera, Fusarium, Mucor, Penicillium, Pestalotiopsis, Restiosporium, Rhizopus, Talaromyces, Trichoderma and Xylaria. Certain assemblages of fungi have specific and distinct relationships with their hosts, especially Xylaria species (e.g., Xylaria magnoliae on Magnolia fruits; X. xanthinovelutina (= X. ianthino-velutina) on Fabaceae pods; X. carpophila on Fagus cupules; X. persicaria on liquidambar fruits). Whether these species occur as endophytes and become saprobes following fruit fall requires further investigation. In this study, we also made several sexual morph collections of sordariomycetous taxa from different seed and fruit substrates mainly from Thailand, with a few from the UK. These include 15 new species, 13 new host records and 1 new geographical record. The new species are described and illustrated.

Os microfungos, especialmente do filo Ascomycota (anamórficos e teleomórficos), podem ser encontrados colonizando uma ampla gama de hospedeiros botânicos, por isso, Hawksworth em 1991 propôs a razão planta: fungo de 1:6. Estudos sistematizados sobre fungos que colonizam espécies de Arecaceae apontam uma razão bem mais elevada de 1:26. Se considerarmos que o número de fungos que ocorrem em palmeiras é grande, pesquisas nesse sentido precisam ser realizadas a fim de ampliarmos o conhecimento. Syagrus coronata (Mart.) Becc. (licuri), espécie adaptada a regiões secas e áridas, é uma Arecaceae de alto valor nutritivo e de grande relevância socioeconômica para as comunidades do semiárido nordestino. O licurizeiro por ser uma planta totalmente aproveitável, vem sendo amplamente explorada e, essa extração tem causado a destruição do mesmo. Esta forma de exploração pode levar a uma diminuição das populações naturais. Neste trabalho, a palmeira S. coronata (licuri) foi escolhida para ser estudada devido a sua grande valia e também pela escassez de pesquisas micológicas para este hospedeiro.
