“…& M.A. Curtis have been reported from different regions of Mexico (Berkeley 1867;Guzmán and Sampieri 1984;Guzmán 1985;Guevara et al 2004;Pérez-Moreno et al 2008;Garibay-Orijel et al 2009;Kong et al 2018;Corona-González 2019). Craterellus confluens was described by Berkeley (1867) from Mexico (Orizaba at central Veracruz state), in a locality relatively close to one of the current study sites in the Municipality of Zentla, Veracruz.…”

Two new species of yellow Cantharellus and a new record of Cantharellus tabernensis associated with tropical species of Quercus are presented, based on the taxonomic study of fresh specimens and in a phylogenetic analysis of transcription elongation factor 1-alpha (tef-1α) and the large subunit of the ribosome (nLSU) sequences. One of the new species proposed here, corresponds to a choice edible mushroom, which, in our molecular phylogeny, resulted in it being related to the group of species around C. lateritius and sister with Craterellus confluens type specimen. This latter is here formally transferred to Cantharellus and consequently a new name, Cantharellus furcatus, is proposed to replace the homonym Cantharellus confluens (Schwein.) Schwein. 1834 a later synonym of Byssomerulius corium. Detailed macroscopic and microscopic descriptions accompanied with illustrations and a taxonomic discussion are presented for each species.

“…A second genome from Laccaria, that of Laccaria amethystina LaAM-08-1, was obtained with paired-end second-generation sequencing technology, also from a monokaryotic strain [34]. L. bicolor and L. amethystina are host generalists and widely distributed; in contrast, L. trichodermophora is restricted to Northern and Central America, and has a strong preference for pine hosts [27,[35][36][37][38][39][40][41][42][43][44]. However, it can shift hosts when outside of its natural distribution [45][46][47].…”

Genome assembly and annotation using short-paired reads is challenging for eukaryotic organisms due to their large size, variable ploidy and large number of repetitive elements. However, the use of single-molecule long reads improves assembly quality (completeness and contiguity), but haplotype duplications still pose assembly challenges. To address the effect of read length on genome assembly quality, gene prediction and annotation, we compared genome assemblers and sequencing technologies with four strains of the ectomycorrhizal fungus Laccaria trichodermophora. By analysing the predicted repertoire of carbohydrate enzymes, we investigated the effects of assembly quality on functional inferences. Libraries were generated using three different sequencing platforms (Illumina Next-Seq, Mi-Seq and PacBio Sequel), and genomes were assembled using single and hybrid assemblies/libraries. Long reads or hybrid assemby resolved the collapsing of repeated regions, but the nuclear heterozygous versions remained unresolved. In dikaryotic fungi, each cell includes two nuclei and each nucleus has differences not only in allelic gene version but also in gene composition and synteny. These heterokaryotic cells produce fragmentation and size overestimation of the genome assembly of each nucleus. Hybrid assembly revealed a wider functional diversity of genomes. Here, several predicted oxidizing activities on glycosyl residues of oligosaccharides and several chitooligosaccharide acetylase activities would have passed unnoticed in short-read assemblies. Also, the size and fragmentation of the genome assembly, in combination with heterozygosity analysis, allowed us to distinguish homokaryotic and heterokaryotic strains isolated from L. trichodermophora fruit bodies.

El avance en el conocimiento sobre la diversidad fúngica en Jalisco se ha dado a través de contribuciones de colectas realizadas en distintos municipios de la entidad; sin embargo aún existen regiones en las que se requiere hacer estudios taxonómicos y ecológicos. Es de suma importancia, dar a conocer nuevos registros para el estado, que incrementen el conocimiento sobre la diversidad fúngica. En este trabajo se realizó la revisión de ejemplares de la colección micológica del herbario IBUG, provenientes de varios municipios. Se realizó un estudio macro y micromorfológico que se llevó a cabo siguiendo las técnicas de rutina en micología y el uso de bibliografía especializada para su determinación. Se aportan cinco registros nuevos para Jalisco, de los cuales cuatro pertenecen a la división Basidiomycota (Battarrea phalloides, Lentinellus ursinus, Russula delica var. centroamericana y Tricholoma caligatum) y uno de Ascomycota (Trichoglossum hirsutum). Se presenta la descripción taxonómica y breve discusión de los taxa, así como fotografías de algunas de las especies incluidas. Esta es una contribución más al conocimiento de los hongos en el estado de Jalisco y micobiota en México.
