“…In the abandoned dual name nomenclature system, the genus Basipetospora was found to be the asexual morph of Monascus and was characterised by the production of aleurioconidia in a basipetal manner from undifferentiated conidiogenous cells that progressively shorten (retrogression, Cole & Samson 1979 ). The name Monascus was recommended over Basipetospora ( Rossman et al. 2016 ).…”

The Eurotiales is a relatively large order of Ascomycetes with members frequently having positive and negative impact on human activities. Species within this order gain attention from various research fields such as food, indoor and medical mycology and biotechnology. In this article we give an overview of families and genera present in the Eurotiales and introduce an updated subgeneric, sectional and series classification for Aspergillus and Penicillium . Finally, a comprehensive list of accepted species in the Eurotiales is given. The classification of the Eurotiales at family and genus level is traditionally based on phenotypic characters, and this classification has since been challenged using sequence-based approaches. Here, we re-evaluated the relationships between families and genera of the Eurotiales using a nine-gene sequence dataset. Based on this analysis, the new family Penicillaginaceae is introduced and four known families are accepted: Aspergillaceae , Elaphomycetaceae , Thermoascaceae and Trichocomaceae . The Eurotiales includes 28 genera: 15 genera are accommodated in the Aspergillaceae ( Aspergillago , Aspergillus , Evansstolkia , Hamigera , Leiothecium , Monascus , Penicilliopsis , Penicillium , Phialomyces , Pseudohamigera , Pseudopenicillium , Sclerocleista , Warcupiella , Xerochrysium and Xeromyces ), eight in the Trichocomaceae ( Acidotalaromyces , Ascospirella , Dendrosphaera , Rasamsonia , Sagenomella , Talaromyces , Thermomyces , Trichocoma ), two in the Thermoascaceae ( Paecilomyces , Thermoascus ) and one in the Penicillaginaceae ( Penicillago ). The classification of the Elaphomycetaceae was not part of this study, but according to literature two genera are present in this family ( Elaphomyces and Pseudotulostoma ). The use of an infrageneric classification system has a long tradition in Aspergillus and Penicillium . Most recent taxonomic studies focused on the sectional l...

“…The diversity of trophic and reproductive strategies of fungi and their often complex lifecycles add further complications. What is perceived as phenotypically distinct entities may be manifestations of one and the same fungus, often representing sexual versus asexual forms (Kendrick 1979 ; Aoki and O'Donnell 1999 ; Covert et al 2007 ; Wingfield et al 2012 ; Rossman et al 2016 ; Tanaka and Honda 2017 ; Tanney and Miller 2017 ). Exemplar cases are the rust fungi (Aime et al 2018 ; Kolmer et al 2018 ), which can produce up to seven morphologically and functionally distinct types of spores (Bruckart et al 2010 ).…”

Unambiguous identification of fungi: where do we stand and how accurate and precise is fungal DNA barcoding?

True fungi (Fungi) and fungus-like organisms (e.g. Mycetozoa, Oomycota) constitute the second largest group of organisms based on global richness estimates, with around 3 million predicted species. Compared to plants and animals, fungi have simple body plans with often morphologically and ecologically obscure structures. This poses challenges for accurate and precise identifications. Here we provide a conceptual framework for the identification of fungi, encouraging the approach of integrative (polyphasic) taxonomy for species delimitation, i.e. the combination of genealogy (phylogeny), phenotype (including autecology), and reproductive biology (when feasible). This allows objective evaluation of diagnostic characters, either phenotypic or molecular or both. Verification of identifications is crucial but often neglected. Because of clade-specific evolutionary histories, there is currently no single tool for the identification of fungi, although DNA barcoding using the internal transcribed spacer (ITS) remains a first diagnosis, particularly in metabarcoding studies. Secondary DNA barcodes are increasingly implemented for groups where ITS does not provide sufficient precision. Issues of pairwise sequence similarity-based identifications and OTU clustering are discussed, and multiple sequence alignment-based phylogenetic approaches with subsequent verification are recommended as more accurate alternatives. In metabarcoding approaches, the trade-off between speed and accuracy and precision of molecular identifications must be carefully considered. Intragenomic variation of the ITS and other barcoding markers should be properly documented, as phylotype diversity is not necessarily a proxy of species richness. Important strategies to improve molecular identification of fungi are: (1) broadly document intraspecific and intragenomic variation of barcoding markers; (2) substantially expand sequence repositories, focusing on undersampled clades and missing taxa; (3) improve curation of sequence labels in primary repositories and substantially increase the number of sequences based on verified material; (4) link sequence data to digital information of voucher specimens including imagery. In parallel, technological improvements to genome sequencing offer promising alternatives to DNA barcoding in the future. Despite the prevalence of DNA-based fungal taxonomy, phenotype-based approaches remain an important strategy to catalog the global diversity of fungi and establish initial species hypotheses.

“…59.1, is applicable to this fungus. Thus, although its sexual morph is still unknown, it is assignable to Golovinomyces, which has priority over the anamorph-typified genus Euoidium that is now a heterotypic synonym of Golovinomyces (Rossman et al 2016), and the name Oidium ocimi is used for this species (see above).…”

Records of Golovinomyces species new to Thailand are described on the hosts Ageratum conyzoides, Bidens pilosa, Dahlia pinnata, D. × hortensis, Helianthus annuus, Lactuca indica, Laggera crispata, Sonchus oleraceus (Asteraceae), Lygisma inflexum (Asclepiadaceae), Myosotis scopioides (Boraginaceae), Coccinia indica, Coccinia grandis (Cucurbitaceae), Vigna umbellata (Fabaceae), Torenia fournieri (Linderniaceae), Plantago major (Plantaginaceae) and Verbena × hybrida (Verbenaceae). The identifications of the particular Golovinomyces species have been performed by means of morphological examinations supplemented by molecular sequence analyses. On the basis of molecular analyses, the powdery mildew on Ocimum tenuiflorum (Lamiaceae) proved to represent a species of its own, which is referred to as Golovinomyces ocimi comb. nov. The application of Oidium ocimi, the basionym of this combination, is determined by lecto-and epitypification. Lygisma inflexum, Laggera crispata and Vigna umbellata are new host records for Golovinomyces worldwide.
