Argentina Kosmimatamyces alatophylus (incl. gen. nov.) soil. Australia Aspergillus banksianus kumbius luteorubrus malvicolor and nanangensis soil, Erysiphe medicaginis leaves Medicago polymorpha Hymenotorrendiella communis on leaf litter Eucalyptus bicostata Lactifluus albopicri austropiperatus Macalpinomyces collinsiae Eriachne benthamii...
Paracoccidioidomycosis (PCM) is a systemic mycosis, widespread in Latin America. PCM granulomatous disease characterized by polymorphism of lesions depending on the pathogen's virulence, immune status host and its genetic susceptibility. The thermodimorphic fungus Paracoccidioides brasiliensis was considered only etiologic agent PCM, yet recent works have shown significant diversity among different strains P. brasiliensis. Therefore, it has been proposed for new species within genus, named...
Objetivou-se avaliar a incidência de fungos e nematoides em sementes Brachiaria sp. Panicum maximum produzidas nos estados Mato Grosso do Sul (MS), (MT), Goiás (GO), Minas Gerais (MG) São Paulo (SP). Os principais encontrados nas foram Bipolaris sp., Curvularia Phoma sp.. As menores incidências destes encontradas das cultivares BRS Piatã Xaraés brizantha decumbens cv. Basilisk, oriundas dos GO, MG MS, respectivamente. Marandu Piatã, provenientes várias regiões, apresentaram elevada...
Fruit rots caused by distinct fungal pathogens are commonly observed on tomatoes (Solanum lycopersicum L.) throughout all major production areas in Brazil. Samples of fruits displaying white mycelial growth associated with a profuse salmon-color sporulation were collected greenhouse-grown Brasília-DF February 2011. The isolated fungus displayed pink-to-white colonies containing several conidiophores conidia. Mycelia hyaline hyphae as much 4 μm diameter; simple or branched, 112 to 300 (360)...
Tectona grandis (teak) is currently expanding as a commercial timber crop in tropical Brazil. Teak trees displaying unusual canker lesions with abundant exudation of viscous resin were observed field inspections Cáceres, Mato Grosso (MT) State, Other symptoms the presence brownish vascular tissue discoloration, heartwood rot (Fig. 1) and dieback. The incidence affected ranged from 5 to 10% across all inspected fields. Affected segments cultivated water agar medium aiming isolate organism...
Four new Asterolibertia species and a variety of Cirsosia splendida, all found on native Cerrado plants, belonging to three host families are described, illustrated named as: A. bahiensis sp. nov. Erythroxylum (Erythroxylaceae); barrinhensis Diospyros burchellii (Ebenaceae); campograndensis Hirtella glandulosa (Chrysobalanaceae); parinaricola Parinari obtusifolia splendida var. laevigata nov., showing both sexual asexual morphs, H. gracilipes (Chrysobalanaceae). Finally, licaniae is reported...
Abstract Hymenaea stigonocarpa , popularly known as ‘jatobá’ or ‘jatobá‐do‐cerrado’, is a native plant widely distributed across Brazilian Cerrado areas. This used for urban afforestation, human and animal feeding, industry. Foliar lesions resembling anthracnose symptoms were observed on H. in natural habitats nurseries. Microscopic examination of acervuli indicated Colletotrichum species the cause symptoms. Based multilocus phylogenetic analyses including data from APN2, APN2‐MAT/IGS, CAL,...
