Known from trees and the tropics: new insights into the species complex.

The species complex (FLSC) currently comprises 11 phylogenetic species, including accepted names such as , , and , which have mostly been reported in association with citrus and coffee. Many varieties were documented by Wollenweber & Reinking (1935), which is indicative of a wider diversity of species within this group. The lack of type material in some cases, especially for the older names, means that definition by molecular phylogeny is very difficult.

Fusarioid keratitis and other superficial infections: A 10-years prospective study from Northeastern Brazil.

Background: Fusarium and allied genera (fusarioid) species are common colonizers of roots and aerial plant parts, or act as phytopathogens in forestry and horticultural or grain crops. However, they can also cause a wide range of infections in humans, including onychomycosis, cutaneous and invasive infections. Fusarioid keratitis is characterized by an infection of the cornea with a suppurative and ulcerative appearance, which may cause damage to vision and permanent blindness.

The genus includes numerous important plant and human pathogens, as well as many industrially and commercially important species. During our investigation of fungal diversity in China, a total of 356 fusarioid isolates were obtained and identified from diverse diseased and healthy plants, or different environmental habitats, i.e.

Citizen science project reveals novel fusarioid fungi () from urban soils.

Soil fungi play a crucial role in soil quality and fertility in being able to break down organic matter but are frequently also observed to play a role as important plant pathogens. As part of a Citizen Science Project initiated by the Westerdijk Fungal Biodiversity Institute and the Utrecht University Museum, which aimed to describe novel fungal species from Dutch garden soil, the diversity of fusarioid fungi ( and other fusarioid genera), which are members of () was investigated. Preliminary analyses of ITS and LSU sequences from more than 4 750 isolates obtained indicated that 109 strains belong to this generic complex.

: more than a node or a foot-shaped basal cell.

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family . Thus, an alternate hypothesis, namely a very broad concept of the genus was proposed. In doing so, however, a significant body of data that supports distinct genera in based on morphology, biology, and phylogeny is disregarded.

Human infectious fungal diseases are increasing, despite improved hygienic conditions. We present a case of gastrointestinal basidiobolomycosis (GIB) in a 20-year-old male with a history of progressively worsening abdominal pain. The causative agent was identified as a novel species.

Redefining species limits in the species complex.

The species complex (FFSC) includes more than 60 phylogenetic species (phylospecies) with both phytopathological and clinical importance. Because of their economical relevance, a stable taxonomy and nomenclature is crucial for species in the FFSC. To attain this goal, we examined type specimens and representative cultures of several species by employing morphology and phylogenetic analyses based on partial gene fragments of the translation elongation factor 1-alpha (), beta-tubulin (), calmodulin (), RNA polymerase largest subunit () and RNA polymerase II second largest subunit ().

Diversity and toxigenicity of fungi and description of sp. nov. from cereals, legumes and soils in north-central Nigeria.

Mycological investigation of various foods (mainly cowpea, groundnut, maize, rice, sorghum) and agricultural soils from two states in north-central Nigeria (Nasarawa and Niger), was conducted in order to understand the role of filamentous fungi in food contamination and public health. A total of 839 fungal isolates were recovered from 84% of the 250 food and all 30 soil samples. Preliminary identifications were made, based on macro- and micromorphological characters.

, a new potential pathogen from a human respiratory sample.

We describe the isolation and characterization of from a bronchoalveolar lavage (BAL) sample of a female patient living in French Guiana with underlying pulmonary infections. Phylogenetic analysis of fragments of the calmodulin (), translation elongation factor (), RNA polymerase second largest subunit (), and β-tubulin () loci revealed that strain CBS 143874 was closely related to isolate NRRL 25615, a known but undescribed phylogenetic species belonging to the African clade of the species complex. The fungus differed phylogenetically and morphologically from related known species, and is therefore described as the new taxon .

The series provides morphological descriptions, information about the pathology, distribution, hosts and disease symptoms for the treated genera, as well as primary and secondary DNA barcodes for the currently accepted species included in these. This third paper in the GOPHY series treats 21 genera of phytopathogenic fungi and their relatives including: , , , , , , , , , , , , , , , , , , , and .

sp. nov. and sp. nov., isolated from marine waters of the Arabian Gulf surrounding Qatar.

The Arabian Gulf surrounding Qatar is distinct from other marine ecosystems due to its high salinity (35-75 PSU) and extreme water temperature fluctuations (11-40 °C). Furthermore, in the last decade, Qatar has been witnessing an industrial boom as well as extensive infrastructure construction activities. Marine micro-organisms, including fungi, remain largely unexplored in the Arabian Gulf.

Removing chaos from confusion: assigning names to common human and animal pathogens in .

The genus encompasses highly prevalent and aggressive human and animal fungal pathogens. Here we assign formal descriptions and Latin binomials to some of the most clinically relevant phylogenetic species of the genus. Three new species, named , and (previously assigned to the informal names '' species complex (FSSC) lineages, FSSC 43, FSSC 7 and FSSC 20, respectively) are described on the basis of multilocus phylogenetic analyses (using , ITS, LSU and loci) and morphological characters.

Numbers to names - restyling the species complex.

The species complex (FIESC) is a phylogenetically species-rich complex that includes over 30 cryptic phylogenetic species, making identification based on phenotypic characters problematic. Several established species known to reside in the FIESC lack type material, further complicating the use of Latin binomials for this complex. To overcome this problem, an informal classification system based on a haplotype nomenclature was introduced to improve communication between researchers in various fields.

Back to the roots: a reappraisal of .

The genus ( species complex) contains saprobes, plant endophytes and pathogens of major economic significance as well as opportunistic animal pathogens. Advances in biological and phylogenetic species recognition revealed a rich species diversity which has largely remained understudied. Most of the currently recognised species lack formal descriptions and Latin names, while the taxonomic utility of old names is hampered by the lack of nomenclatural type specimens.

New endemic species hitch-hiking with pathogenic strains causing Panama disease in small-holder banana plots in Indonesia.

species are well known for their abundance, diversity and cosmopolitan life style. Many members of the genus are associated with plant hosts, either as plant pathogens, secondary invaders, saprotrophs, and/or endophytes. We previously studied the diversity of species in the species complex (FOSC) associated with Fusarium wilt of banana in Indonesia.
