“…L. ohiensis). Recently, new species of Laccaria in the northern hemisphere have been described, or suggested based on molecular analysis (Vincenot et al, 2012;Popa et al, 2014Popa et al, , 2016Montoya et al, 2015). An analysis of a Laccaria ITS sequence dataset consisting of > 800 sequences (data not shown) indicates that two of the five new species from these studies (L. aurantia and L. fulvogrisea) are represented in the Laccaria Systematics dataset.…”

“…Several studies have described the diversity of Laccaria from various regions (Mueller, 1992;Osmundson et al, 2005;Vincenot et al, 2012;Sheedy et al, 2013;Wilson et al, 2013;Popa et al, 2014Popa et al, , 2016Montoya et al, 2015). These studies are limited to relatively small geographical areas and/or datasets that do not resolve critical systematic relationships within the genus.…”

Summary A systematic and evolutionary ecology study of the model ectomycorrhizal (ECM) genus Laccaria was performed using herbarium material and field collections from over 30 countries covering its known geographic range.A four‐gene (nrITS, 28S, RPB2, EF1α) nucleotide sequence dataset consisting of 232 Laccaria specimens was analyzed phylogenetically. The resulting Global Laccaria dataset was used for molecular dating and estimating diversification rates in the genus. Stable isotope analysis of carbon and nitrogen was used to evaluate the origin of Laccaria's ECM ecology.In all, 116 Laccaria molecular species were identified, resulting in a near 50% increase in its known diversity, including the new species described herein: Laccaria ambigua. Molecular dating indicates that the most recent common ancestor to Laccaria existed in the early Paleocene (56–66 million yr ago), probably in Australasia. At this time, Laccaria split into two lineages: one represented by the new species L. ambigua, and the other reflecting a large shift in diversification that resulted in the remainder of Laccaria. L. ambigua shows a different isotopic profile than all other Laccaria species.Isotopes and diversification results suggest that the evolution of the ECM ecology was a key innovation in the evolution of Laccaria. Diversification shifts associated with Laccaria's dispersal to the northern hemisphere are attributed to adaptations to new ecological niches.

“…Molecular analysis has increased the accuracy of fungal identification [12][13][14]. Identification of Laccaria species based on molecular analysis has become possible as a result of the accumulation of sequence data in GenBank through active phylogenetic studies of Laccaria using the internal transcribed spacer (ITS) region, nuclear 28S rDNA (28S), RNA polymerase II subunit 2 (rpb2), and translation elongation factor 1-a (tef1) [4,10,11,15,16]. The accumulated sequence data also provide an advantage of promptly discovering new or rare species.…”

Two New Species of Laccaria (Agaricales, Basidiomycota) from Korea

et al. 2020

View full text Add to dashboard Cite

Species of Laccaria (Hydnangiaceae, Agaricales, and Basidiomycota) are well-known ectomycorrhizal symbionts of a broad range of hosts. Laccaria species are characterized by brown, orange, or purple colored basidiocarps, and globose or oblong, echinulate and multinucleate basidiospores. While some Laccaria species are easily identified at the species level using only the morphological characteristics, others are hard to distinguish at the species level due to small differences in morphology. Heretofore, ten Laccaria species have been reported in Korea. While studying the fungal diversity in the National Parks of Korea, two new Laccaria species were discovered. Species identification was done based on molecular analyses (ITS, 28S rDNA, rpb2, and tef1), then were confirmed by their corresponding morphologies. The two newly discovered Laccaria species are proposed here as Laccaria macrobasidia and Laccaria griseolilacina. The unique morphological characters of L. macrobasidia that distinguish it from its closely related species are orange-brown colored basidiocarp, long basidia and the absence of cheilocystidia. L. griseolilacina is characterized by a light grayish lavender-colored pileus and the absence of cheilocystidia. Two new species are described and illustrated in the present paper.

“…Laccaria (Agaricales) is considered a model genus for understanding ectomycorrhizal (ECM) ecology and evolution (Martin et al, 2008;Wilson et al, 2017a). In a little more than a decade, studies incorporating morphological and molecular data have described 22 Laccaria species worldwide: one from New Zealand (Wilson et al, 2017a), 18 from Asia (Wilson et al, 2013;Popa et al, 2014;Vincenot et al, 2017;Cho et al, 2018;Latha et al, 2019;Li, 2020), and three from subtropical and tropical North and Central America (Montoya et al, 2015;Popa et al, 2016;Ramos et al, 2017).…”

Novel Laccaria Species From Juglandaceae Forest in Panama With Notes on Their Ecology

et al. 2020

View full text Add to dashboard Cite

Since 2013 there have been 22 new species of Laccaria described worldwide. Only three of these represent species from the neotropics. In Panama, Laccaria is abundant in monodominant Oreomunnea mexicana (Juglandaceae) forests based on sporocarps and environmental sequencing of roots. This study uses a combination of morphological and phylogenetic evidence to document up to seven species of Laccaria from these forests, one previously described, three described as new, and three requiring more data before being formally described. Molecular data used for phylogenetic analysis include the nuclear ribosomal ITS and 28S regions, along with TEF1 and RPB2. Laccaria stellata, has previously been reported from O. mexicana cloud forests of Panama. Laccaria dallingii sp. nov., L. nitrophila sp. nov., and L. fortunensis sp. nov. are described as new based on morphology and phylogenetic analysis of multiple collections. A taxon referred to as "PAN sp3" is resolved sister to L. stellata. Phylogenetic analysis also resolved two separate clades of Panamanian Laccaria as sister to L. roseoalbescens, a species previously described from Mexico. These three taxa are not described in this paper as there is too little material from which to make effective morphological descriptions even though their placement in phylogenetic analysis identify them as being unique. Ecologically, all described species except for L. fortunensis were amplified from O. mexicana ectomycorrhizal root tips. L. nitrophila was one of the most recovered species from the roots of O. mexicana in a previous study, and it has been shown to respond positively to long term nitrogen addition. Our results expand the knowledge of Laccaria diversity for Central America and highlight that at least some species of Laccaria are nitrophilic in neotropical Juglandaceae forests as well as in temperate forests.
