Amanita amerivirosa is proposed as new and is assignable to Amanita section Phalloideae. For decades,the species was widely included in North American field guides under the name of a European species —Amanitavirosa. Several new primers are described along with associated methodology.

Article
A revision of twenty-eight type collections of Psilocybe is presented. Descriptions of thetypes were completed with characteristics not previously mentioned such as the presence of pseudorhizain the stipe, pileocystidia, caulocystidia and pleurocystidia, as well as the subhymeniumtype and the arrangement of the hyphae in the pileus trama. From this...

Seven species of bioluminescent fungi are recorded from the cloud forests in Mexico. Six represent new species belonging to the genus Mycena, whereas Mycena globulispora is a new distribution record for the country. Descriptions, illustrations, photographs, and an identification key to bioluminescent fungi species from Mexico are provided. Sequence...

Two species of bioluminescent fungi are recorded from Mexico. Mycena stylobates is characterized by a pubescent basal disc, pileus with a separable gelatinous pellicle, and cheilocystidia with coarse excrescences, and represents a new record for the country. Panellus stipticus, which is distinguished by having rounded flabelliform basidiomata and a...

This is the first internal transcribed spacer (ITS) phylogeny of the enigmatic genus Cantharocybe and includes ITS sequences from two out of the three holotype collections. Two species are reported from the Americas and only a single species from Asia. Additionally, a collection of Cantharocybe virosa collected from tropical Bangladesh was included...

Psilocybe allenii is a new bluing wood-rotting species from the Pacific Coast, USA. Both morphological and molecular features (ITS rDNA phylogeny) indicate its close relationship to Psilocybe cyanescens Wakef. Despite the shape and size of spores and cystidia of this new species falling within the variability of P. cyanescens, P. allenii can be dis...

... The Bayesian inference of phylogeny based on ITS and LSU data ( Figure 1) is consistent with previously published organization of Amanita sect. Phalloideae [31,[33][34][35][36][37]64], although the limited signal provided by the ribosomal regions alone does not resolve most supraspecific nodes supported by the analyses, including protein-coding genes. The Mediterranean 'destroying angels' include at least seven different species. ...
... 2006); from these, 35 species and 9 varieties have been reported to be used by ethnic groups and mestizos mainly in central and southern Mexico. According to modern species concepts, these 44 taxa correspond to 14 currently valid species (Cortés-Pérez et al., 2021;Guzmán 2008) (Table 1). ...
... The genetic sequences obtained from PCR were entered into a standard BLAST search in the GenBank database in order to verify the primary identity of the novel fungus. The other sequences used in the phylogenetic analyses were obtained from GenBank, and another BLAST search was used to identify sequences with high similarity indices and sequences identified in recently published data (Cortés-Pérez et al. 2019;Karunarathna et al. 2020). Two strains of Mycena abramsii (HMJAU43523 and HMJAU43606) were used as the outgroup taxa. ...
... In the current study, pairwise analyses of aligned overlapping ITS sequences have been used to supplement morphological observations and inform taxonomic decisions, which have been made based on a combination of morphological, ecological, and molecular data. The documentation of bioluminescent fungi from Mexico is recent (Cortés-Pérez et al. 2017). Here, we treat an additional seven species of Mycena, increasing the current number of known bioluminescent species from cloud forests of Mexico to nine. ...
... Stipe covering mostly with appressed, slightly interwoven hyphae near the base, and scattered caulocystidia like those of the cheilocystidia. Clamp connections present in most of all hyphal septa (Bigelow and Smith 1973;Ovrebo et al. 2011;Lodge et al. 2014;Hosen et al. 2016). ...
... The ITS rDNA region (containing ITS1-5.8S-ITS2 sequences), which is commonly used for the separation and identification of agaric species (e.g., Adamčík, Jančovičová, Looney, Adamčíková, Griffith, et al., 2017;Borovička et al., 2012;Miller & Buyck, 2002;Schoch et al., 2012;Zhang et al., 2004), was used to confirm the taxonomic affiliation of the collected material and to infer the evolutionary relationships between H. variablipes and other representative taxa in this study. Genomic DNA isolates were extracted from two dried specimens (ChP-2014-0007, ChP-2016-0004) using the CTAB procedure described by Murray and Thompson (1980). ...
