Lactocollybia is poorly known in China. Prior to this report, only a single species of this genus was reported from tropical Yunnan Province in the country. In this study, Lactocollybia subvariicystis is reported as a new species. It is characterized by its mycenoid habit with white basidiomata, white, adnate to sinuate lamellae, numerous gloeocyst...

Only a few Crepidotus species have been previously reported from subalpine areas of China. Members of Crepidotus possessing an orange- yellow pileus are rare in China as well. Here, we describe Crepidotus yuanchui, a new species characterized by an orange-yellow pileus, ovoid basidiospores, and abundant cylindric to narrowly utriform cheilocystidia...

... Lactocollybia is divided into five small sections based on the basidiome structure (collybioid, mycenoid, omphalioid, or pleurotoid), pigmentation, subhymenial structure; the presence or absence of latex, clamp connections, and gloeocystidia; and habit on living tree stumps, bark, or fallen fruit (Singer 1970(Singer , 1986Hosen & al. 2016;Senthilarasu & Kumaresan 2016). Lactocollybia variicystis is referred to L. sect. ...
... Sequences were compared using the BLAST tool available on the NCBI database. For phylogenetic reconstruction, BLAST searches were executed to find sequences showing maximum identity, and those referred by Hosen & al. (2016) were retrieved from GenBank. The multiple sequences were aligned using MUSCLE (Edgar 2004), then manually adjusted in BioEdit (Hall 1999). ...

During surveys of macrofungi in Pakistan, eight specimens belonging to the genus Lactocollybia were collected from the plains of Punjab and foothills of Murree. Morphological studies and molecular characterization refer all collections to a single species, Lactocollybia variicystis, previously restricted to Africa and Europe; this is the first report from Asia. Except for geography, no significant differences were found among African, European, and Pakistani collections.
... Lactocollybia is a genus in the family Marasmiaceae (Agaricales). This worldwide genus includes 17-19 species (Kirk et al., 2008;Hosen et al., 2016). These species mainly occurr in tropical and subtropical regions (Hausknecht and Krisai-Greilhuber, 2008;Hosen et al., 2016). ...

These species mainly occurr in tropical and subtropical regions (Hausknecht and Krisai-Greilhuber, 2008;Hosen et al., 2016). Species of Lactocollybia are classified according to several characters like habit, habitat, clamp-connections, presence or absence of the gelatinous film and types of cystidia (Singer, 1986, Hosen et al., 2016. ...

A rare agaric, Lactocollybia variicystis D.A. Reid and Eicker (Family: Marasmiaceae) is identified as a new record to Iraqi macromycota, based on morphological characteristics and molecular analysis. Descriptions, color photographs, comments and phylogenetic analysis based on ITS rDNA sequence data are given.
The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406–430 Mya, classes are 211–383 Mya, and orders are 99–323 Mya, which are largely consistent with previous studies. In this study, all phylogenetically supported families were dated, with the families of Agaricomycotina diverging from 27–178 Mya, Pucciniomycotina from 85–222 Mya, and Ustilaginomycotina from 79–177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of their phylogeny and evolution.
