Abstract It is now a decade since The International Commission on the Taxonomy of Fungi (ICTF) produced an overview requirements and best practices for describing new fungal species. In meantime Code Nomenclature algae, fungi, plants (ICNafp) has changed from its former name (the Botanical ) introduced formal valid publication species scientific names, including separation provisions specific to organisms treated as fungi in Chapter F. Equally transformative have been changes data...

Molecular phylogenies using 1–4 gene regions and information on ecology, morphology pigment chemistry were used in a partial revision of the agaric family Hygro- phoraceae. The phylogenetically supported genera we recognize here Hygrophoraceae based these previous analyses are: Acantholichen, Ampulloclitocybe, Arrhenia, Cantharellula, Cantharocybe, Chromosera, Chrysomphalina, Cora, Corella, Cuphophyllus, Cyphellostereum, Dictyonema, Eonema, Gliophorus, Haasiella, Humidicutis, Hygroaster,...

The genus Pythium (nom. cons.) sensu lato (s.l.) is composed of many important species plant pathogens. Early molecular phylogenetic studies suggested paraphyly Pythium, which led to a formal proposal by Uzuhashi and colleagues in 2010 split the into stricto (s.s.), Elongisporangium, Globisporangium, Ovatisporangium (= Phytopythium), Pilasporangium using morphological characters phylogenies mt cytochrome c oxidase subunit 2 (cox2) D1-D2 domains nuc 28S rDNA.

The rapid pace of name changes medically important fungi is creating challenges for clinical laboratories and clinicians involved in patient care. We describe two sources change which have different drivers, at the species versus genus level. Some suggestions are made here to reduce number changes. urge taxonomists provide diagnostic markers taxonomic novelties. Given instability phylogenetic trees due variable taxon sampling, we advocate maintain genera largest possible size. Reporting...

Based upon molecular studies, genus is subdivided into stricto ( Agaricaceae ), Coprinellus P. Karst., Coprinopsis Parasola gen. nov. in new family Psathyrellaceae. The nomenclatural history typifications names previously treated as synonyms are reviewed. It demonstrated that taxonomic characters...

Maps showing the North American distributions of 74 species fleshy fungi, mainly Agaricales, are used to demonstrate variations in fungal ranges. Each map is based on examined specimens or selected literature. The maps arranged show floristic patterns, while text grouped along worldwide patterns. Range patterns resemble those reported for vascular plants, ascolichens, and bryophytes. names Hypholoma flavifolium (Smith) comb.nov. Strobilurus trullisatus var. montezumae (Singer) comb. &...

We explored evolutionary relationships within the Lyophyllaceae by combining sequence data from six loci. The most likely phylogram led us to reconsider classification with recognition of two new genera (Myochromella and Sagaranella) based on ecological and/or morphological distinctiveness. are ecologically highly diversified our phylogeny suggests that four five transitions free-living parasitic or mutualistic lifestyles have occurred family.

Chromosera cyanophylla was initially described from Europe and, when it named type of the genus, thought to be distributed throughout and North America. Molecular phylogenies revealed that “cyanophylla” eastern western America represent two separate species neither is conspecific with European C. nor more recently ambigua.

The genus Lentinus (Polyporaceae, Basidiomycota) is widely documented from tropical and temperate forests taxonomically controversial. Here we studied the relationships between subg. sensu Pegler (i.e. sections Lentinus, Tigrini, Dicholamellatae, Rigidi, Lentodiellum Pleuroti polypores that share similar morphological characters). We generated sequences of internal transcribed spacers (ITS) partial 28S regions nuc rDNA genes encoding largest subunit RNA polymerase II (RPB1), focusing on...

AbstractThe rust species Puccinia graminis and P. striiformis sensu stricto are important cereal pathogens, most well-known for causing the diseases stem stripe on wheat generating significant yield losses. Early accurate detection of pathogens would facilitate effective control diseases. In present study, we developed real-time PCR assays to detect specific lineages that include each complex, as identified using multi-gene DNA sequence analyses. Four loci, a comprehensive set target closely...
