Two new species of Lactifluus subgenus Lactifluus were discovered during a three-year monitoring of the ectomycorrhizal fungi in a tropical oak forest from central Veracruz, Mexico. Systematic sampling of basidiomes allowed recording of the morphological variation of fruit-bodies in different growth stages along with their fructification season. Both new species were distinguished, based on macro- and micromorphological features and on molecular data. A phylogenetic analysis of a concatenated nuc rDNA ITS, D1 and D2 domains of nuc 28S rDNA (LSU) and the 6-7 region of the second largest subunit of the RNA polymerase II (2) sequence dataset of species of is provided. In the phylogeny inferred, one of the new species is sister to Van de Putte, K. Das & Verbeken and the other belongs to the group of species of (L.) Kuntze, sister to an unidentified species from U.S.A. The studied taxa grow under in the study site. The species are presented and illustrated here.

We present a proposal of two new species of discovered in tropical oak forests from central Veracruz, Mexico. Both species were distinguished based on macro and micro-morphologic features and supported with a molecular phylogenetic analysis, based on sequences of nuc rDNA ITS, D1, D2 and D3 domains of nuc 28S rDNA (LSU), and transcription elongation factor 1-alpha (tef-1α). In the phylogenetic reconstruction inferred, the new species clustered in two different clades related to species from USA, Costa Rica and Panama. The recollection of fructifications in monodominant stands of either or , allowed recognizing the distribution of one of the species under both species, and the other under only. Detailed macro and microscopic descriptions accompanied by illustrations, photos and a taxonomic discussion are provided.

Mycologia 2018 Nov-Dec;110(6):1033-1046. Epub 2018 Nov 27.

a Red Biodiversidad y Sistemática, Instituto de Ecología A.C ., P.O. Box 63, Xalapa, Veracruz , 91000 , México.

Two species of Lactarius are documented from fragments of tropical lowland oak forest in central Veracruz. Lactarius trichodermoides, described here as new, was found in association with Quercus sapotifolia and Lactarius subplinthogalus with Quercus glaucescens. Both Lactarius species were identified morphologically and supported by phylogenetic analyses of nuc rDNA internal transcribed spacers (ITS1-5.8S-ITS2) and D1-D2 domains of nuc 28S rDNA sequences. Confirmation of mycobionts in ectomycorrhizal (ECM) associations was verified by molecular identification of ECM root tips. Detailed macroscopic and microscopic descriptions and photographs and illustrations of basidiomes and ectomycorrhizas are presented. The new binomial Lactarius chiangmaiensis is proposed for L. subplinthogalus var. chiangmaiensis.

, a new species from tropical forests in eastern Mexico.

MycoKeys 2018 20(32):91-109. Epub 2018 Mar 20.

Red Biodiversidad y Sistemática, Instituto de Ecología A.C., P.O. Box 63, Xalapa, Veracruz, 91000, México.

During explorations of tropical oak forests in central Veracruz (eastern Mexico), the authors discovered a species that produces basidiomes with strikingly violet pileus and a hymenium with yellow, raised gill-like folds. It is harvested locally and valued as a prized edible wild mushroom. Systematic multiyear sampling of basidiomes allowed the recording of the morphological variation exhibited by fresh fruit bodies in different growth stages, which supports the recognition of this species from others in the genus. Two molecular phylogenetic analyses based on a set of sequences of species of all major clades in , one including sequences of the transcription elongation factor 1-alpha (tef-1α) and a combined tef-1α and nLSU region (the large subunit of the ribosome), confirm the isolated position of the new species in a clade close to from USA, in the subgenus Cantharellus. Detailed macroscopic and microscopic descriptions, accompanied by illustrations and a taxonomic discussion are presented.

A new species and a new record of (Fungi, Basidiomycota) found in a relict forest of the endangered Fagus grandifolia var. mexicana.

MycoKeys 2017 27(27):77-94. Epub 2017 Nov 27.

Red Biodiversidad y Sistemática, Instituto de Ecología, A.C., P.O. Box 63, Xalapa, Veracruz 91000, Mexico.

Two species of discovered in relicts of Fagus grandifolia var. mexicana forests in eastern Mexico are described based on the macro- and micromorphological features, and their identity supported by molecular analysis of the internal transcribed spacer (ITS) and large subunit (LSU) of the ribosomal RNA gene. The phylogeny obtained here showed that one of the Mexican species is nested in an exclusive clade which in combination with its striking morphological features, infers that it represents a new species, while the other species is placed as a member in the clade. This is the first report in Mexico of with Fagus grandifolia var. mexicana trees, with which the reported species may form ectomycorrhizal association. Descriptions are accompanied with illustrations of macro- and micromorphological characters and a discussion of related taxa are presented.

Two new Lactarius species from a subtropical cloud forest in eastern Mexico.

Mycologia 2016 09 22;108(5):967-980. Epub 2016 Aug 22.

Biodiversity and Systematics, Institute of Ecology AC, PO Box 63, Xalapa, Veracruz 91000, Mexico.

Two species of Lactarius from the subtropical montane cloud forest of central Veracruz are described as new. Both species are placed in subgenus Lactarius based on an accurate study of macro- and micromorphological features and supported by molecular phylogenetic analyses of a single nuc rDNA ITS1-5.8S-ITS2 (ITS), a concatenated ITS, D1, and D2 domains of nuc 28S rDNA (28S), and part of the second largest subunit of the RNA polymerase II (rpb2) (6-7 region) sequence datasets. In the phylogenetic reconstruction presented, the two species appear nested in two clearly distinct, well supported clades that reveal their phylogenetic position among members of subgenus Lactarius (= subg. Piperites s. auct.), a complex group of which a worldwide phylogeny requires further study. According to field observations, both taxa are possible ectomycorrhizal associates of Quercus spp. and one of Fagus grandifolia var. mexicana Taxonomic descriptions based on the study of specimens gathered during fieldwork from 2012 to 2014 are presented. Descriptions are accompanied with illustrations of macro and micromorphological characters and a discussion of related species is provided.

The ectomycorrhizas of Lactarius cuspidoaurantiacus and Lactarius herrerae associated with Alnus acuminata in Central Mexico.

Mycorrhiza 2015 Aug 27;25(6):457-67. Epub 2015 Jan 27.

Biodiversidad y Sistemática, Instituto de Ecología, A.C., P.O. Box 63, Xalapa, Veracruz, 91000, México,

Two pure Alnus acuminata stands established in a montane forest in central Mexico (Puebla State) were monitored between 2010 and 2013 to confirm and recognize the ectomycorrhizal (EcM) systems of A. acuminata with Lactarius cuspidoaurantiacus and Lactarius herrerae, two recently described species. Through comparison of internal transcribed spacer (ITS) of nuclear ribosomal DNA sequences from basidiomes and ectomycorrhizas sampled in the forest stands, we confirmed their ectomycorrhizal association. The phytobiont was corroborated by comparing ITS sequences obtained from EcM root tips and leaves collected in the study site and from other sequences of A. acuminata available in Genbank. Detailed morphological and anatomical descriptions of the ectomycorrhizal systems are presented and complemented with photographs.

Two new species of Lactarius associated with Alnus acuminata subsp. arguta in Mexico.

Mycologia 2014 Sep-Oct;106(5):949-62. Epub 2014 Jun 3.

Biodiversidad y Sistemática, Instituto de Ecología, A.C., P.O. Box 63, Xalapa, Veracruz 91000, Mexico.

In pure stands of Alnus acuminata subsp. arguta trees from Sierra Norte de Puebla (central Mexico) two undescribed ectomycorrhizal species of Lactarius were discovered. Distinction of the two new species is based on morphological characters and supported with phylogenetic analyses of the nuclear ribosomal DNA ITS region and part of the gene that encodes for the second largest subunit of RNA polymerase II (rpb2). The phylogenies inferred recovered the two species in different clades strongly supported by posterior probabilities and bootstrap values. The new Lactarius species are recognized as part of the assemblage of ectomycorrhizal fungi associated with Alnus acuminata. Information about these taxa includes the morphological variation achieved along 16 monitories 2010-2013. Descriptions are provided. They are accompanied by photos including SEM photomicrographs of basidiospores and information on differences between them and other related taxa from Europe and the United States.

Morphological and molecular identification of the ectomycorrhizal association of Lactarius fumosibrunneus and Fagus grandifolia var. mexicana trees in eastern Mexico.

Mycorrhiza 2012 Nov 9;22(8):583-8. Epub 2012 Mar 9.

Biodiversidad y Sistemática, Instituto de Ecología, A.C., Xalapa, Veracruz, Mexico.

A population of Fagus grandifolia var. mexicana (covering ca. 4.7 ha) is established in a montane cloud forest refuge at Acatlan Volcano in eastern Mexico (Veracruz State), and it represents one of only ten populations of this species known to occur in the country (each stand covers ca. 2-35 ha in extension) and one of the southernmost in the continent. Sporocarps of several ectomycorrhizal macrofungi have been observed in the area, and among them, individuals of the genus Lactarius are common in the forest. However, the morphological and molecular characterization of ectomycorrhizae is still in development. Currently, two species of Lactarius have been previously documented in the area. Through the phylogenetic analysis of the internal transcribed spacer (ITS) region from basidiomes and ectomycorrhizae, we identified the Lactarius fumosibrunneus ectomycorrhiza. The host, F. grandifolia var. mexicana, was determined comparing the amplified ITS sequence from ectomycorrhizal root tips in the GenBank database with Basic Local Alignment Search Tool. The mycorrhizal system of L. fumosibrunneus is monopodial-pyramidal, characterized by its shiny, white to silver and pruinose surface, secreting a white latex when damaged, composed of three plectenchymatous mantle layers, with diverticulated terminal elements at the outer mantle. It lacks emanating hyphae, rhizomorphs, and sclerotia. A detailed morphological and anatomical description, illustrations, and photographs of the ectomycorrhiza are presented. The comparison of L. fumosibrunneus and other Lactarius belonging to subgenus Plinthogalus is presented.

Crepidotus crocophyllus found in Costa Rica and Mexico and revision of related species in subsection Fulvifibrillosi.

Mycologia 2008 Mar-Apr;100(2):335-46

Biodiversidad y Sistemática, Instituto de Ecología, A. C., P.O. Box 63, Xalapa, Veracruz 91000, Mexico.

The study of Crepidotus specimens collected in Costa Rica and Mexico revealed that C. crocophyllus occurs in the tropical and subtropical forests of both countries. Type specimens of seven species related to C. crocophyllus in subsection Fulvifibrillosi s. Hesler and Smith were re-examined. Based on the morphological features, specimens supporting C. appalachianensis, C. aureifolius, C. distortus, C. subaureifolius and C. subnidulans are interpreted to be C. crocophyllus, thus all herein are proposed as its synonyms. Furthermore A. nephrodes is confirmed as a synonym of Crepidotus crocophyllus while Agaricus malachius, long considered contaxic with the former, is proposed as synonym of Crepidotus applanatus. The known records of C. crocophyllus indicate a wide but fragmented range of extension of the taxon throughout the Americas. Description, illustrations of microscopic features and discussions are provided.
