This article is the ninth in series of Fungal Diversity Notes, where 107 taxa distributed three phyla, nine classes, 31 orders and 57 families are described illustrated. Taxa present study include 12 new genera, 74 species, combinations, two reference specimens, a re-circumscription epitype, 15 records sexual-asexual morph connections, hosts geographical distributions. Twelve genera comprise Brunneofusispora, Brunneomurispora, Liua, Lonicericola, Neoeutypella, Paratrimmatostroma,...

Until now, only Lasiodiplodia theobromae has been reported in association with gummosis and dieback of cashew plants other tropical fruit northeastern Brazil. This study aims to identify characterize species associated on grown Ceará, Paraíba, Pernambuco, Piauí Rio Grande do Norte States Brazil a description two new species: caatinguensis sp. nov. pontae Fungal identification was accomplished using combination morphophysiological pathogenic characteristics, together phylogenetic analyses...
Bat caves are very special roosts that harbour thousands of bats one or more species. Such sites may hold an incredible “dark fungal diversity” which is still underestimated. We explored the culturable richness in air, on bats, and guano a bat cave Brazil’s Caatinga dry forest. Fungal abundance was 683 colony-forming units (CFU) guano, 673 CFU 105 bats. Based morphological phylogenetic analysis ITS, LSU, TUB2 sequences, isolates 59 taxa belonging to 37 genera phyla Ascomycota (28 genera,...
The authors describe ten new taxa for science using mostly both morphological and molecular data. In Ascomycota, descriptions are provided Bambusistroma didymosporum gen. et spec. nov. (Pleosporales), Neodeightonia licuriensis sp. (Botryosphaeriales) Camposporium himalayanum (Fungi imperfecti). Zygomycota, Gongronella guangdongensis (Mucorales) is described. Finally, in Basidiomycota Boidinia parva Russula katarinae (Russsulales), Gloiocephala parvinelumbonifolia (Agaricales), Hypochnicium...
Coconut palm (Cocos nucifera L.) is one of the most important perennial tropical crops. Stem-end rot major postharvest disease coconut in Brazil. The fungus Lasiodiplodia theobromae only species that has been reported to be associated with this disease. However, a comprehensive study elucidating true identity pathogen molecular tools never conducted. In recent years, new have proposed after studies were performed, indicating existence complex. aims research etiology stem-end immature based...
Despite the occurrence of several diseases cassava, cassava black root rot (CBR) represents one main limiting factor for crop rentability in world. However, etiology CBR is complex and it needs to be revised based on current molecular analysis. On this work, morphological studies allowed identification three species Botryosphaeriaceae causing disease states Maranhão Paraíba, Brazil, namely: Lasiodiplodia euphorbicola, pseudotheobromae Neoscytalidium hyalinum. This first report these fungal...
Here, Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated endophyte Mimosa tenuiflora causing post-harvest rot disease on fruits of Psidium guajava, respectively. Diaporthe inconspicua is emended to include a more detailed morphological description. egyptiaca reported the Americas while Umbelopsis isabellina endophyte.
Abstract The sweet potato is of great socioeconomic importance in Brazil and throughout the world. Among fungal pathogens associated with root diseases this crop, Fusarium particular due to diversity species, pathogenic potential their various hosts ability survive inside plants as endophytes without apparently causing damage. objective work was identify fusarioid genera from stems roots symptomatic asymptomatic plants. identification species based on multilocus phylogenetic analysis...
In Brazil, the Annonaceae species Annona muricata , A. squamosa cherimola and atemoya (a hybrid of ) are cultivated in several regions, produce fruits that highly appreciated by consumers great economic importance. Among diseases can affect these crops, dieback is one most important, causing damage and, severe cases, death plants. Due to lack suitable diagnostic studies up now, this work aimed identify Botryosphaeriaceae cause on Brazil. Based combined phylogenetic analyses ITS, TEF‐1α TUB2...
Abstract The sweet potato ( Ipomoea batatas ) is characterized by the production of tuberous roots rich in starch and one most produced consumed vegetables Brazil. Botryosphaeriaceae, among other fungi, are known to cause root stem rot potato. However, no representative accurate study has been performed for correct identification these fungal species Therefore, this aimed identify Botryosphaeriaceae associated with confirm their pathogenicity. Tuberous stems symptoms were collected fields...
Seventy-eight Rhizoctonia isolates were obtained from brassicas in five Brazilian states between 2015 and 2017. The identified by phylogenetic analysis of the rDNA internal transcribed spacer region (ITS) tested for pathogenicity aggressiveness. Sixty-eight as R. solani 10 binucleate Rhizoctonia. most prevalent anastomosis group (AG) was AG-4 HG-I (83.3% isolates), followed AG-A (7.7%), AG-1 IB (2.6%), AG-G AG-R (2.6%) AG-2-2 IIIB (1.3%). widely distributed recovered all sampled, including...
Physic nut (Jatropha curcas L.; Euphorbiaeae) has become important in Brazil due to its potential as a feedstock for biodiesel production. In October 2010, during routine monitoring of fields the state Piauí, several plants were observed with symptoms collar and root rot. Initially, appeared withered chlorotic, later became defoliated. Roots collars affected also rotten black fungal structures directly observed. Symptomatic tissue fragments 5 mm diameter washed 70% ethanol, 1% sodium...
