“…Macroscopic features of L. griseolilacina are similar to those of Laccaria species with lavender colored basidiocarps, namely L. amethystina, L. japonica, L. moshuijun, and L. vinaceoavellanea. L. griseolilacina has a light grayish lavender colored basidiocarp while L. amethystina and L. japonica have deep purple colored basidiocarps when fresh [37]. L. griseolilacina and L. vinaceoavellanea have similar colors of basidiocarps when they are young.…”

“…However, L. griseolilacina has a smaller size of basidiocarp than L. vinaceoavellanea (30-90 mm wide) [38]. L. amethystina is only distributed in Europe and not in Asia [37], so it is regionally distinct from L. griseolilacina. L. griseolilacina can be differentiated from L. moshuijun, which has a variable shape of cheilocystidia (clavate, flexuose dichotomy, or trichotomy), by the lack of cheilocystidia [37].…”

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

et al. 2020

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.

“…For example, fungal communities associated with the widespread seagrass Syringodium isoetifolium from across the Indonesian archipelago are highly differentiated on either side of Wallace's line (Wainwright, Zahn, Arlyza, & Amend, ). Likewise, Vincenot et al () report strong geographic structuring in a basidiomycete that disperses via aerial spores. These findings refute the expectation that species with high dispersal potential will show limited differentiation throughout their ranges.…”

Marine fungal biodiversity remains vastly understudied, and even less is known of their biogeography and the processes responsible for driving these distributions in marine environments. We investigated the fungal communities associated with the seagrass Enhalus acoroides collected from Singapore and Peninsular Malaysia to test the hypothesis that fungal communities are homogeneous throughout the study area. Seagrass samples were separated into different structures (leaves, roots, and rhizomes), and a sediment sample was collected next to each plant. Amplicon sequencing of the fungal internal transcribed spacer 1 and subsequent analysis revealed significant differences in fungal communities collected from different locations and different structures. We show a significant pattern of distance decay, with samples collected close to each other having more similar fungal communities in comparison with those that are more distant, indicating dispersal limitations and/or differences in habitat type are contributing to the observed biogeographic patterns. These results add to our understanding of the seagrass ecosystem in an understudied region of the world that is also the global epicenter of seagrass diversity. This work has implications for seagrass management and conservation initiatives, and we recommend that fungal community composition be a consideration for any seagrass transplant or restoration programme.

“…& Broome, Russula, and Sparassis Fr. as well as Lactarius, are divergent from their European and North American counterparts, and many specimens were reported as new species (Zhao et al 2013;Lee et al 2017;Vincenot et al 2017;Cho et al 2018;Cui et al 2018). Thus, it is likely that the diversity of Korean Lactarius taxa is different from what is currently described.…”

Taxonomic revision of the genus Lactarius (Russulales, Basidiomycota) in Korea

The genus Lactarius Pers. (Russulales) is a cosmopolitan group of Basidiomycota that forms ectomycorrhizal relationships primarily with both deciduous and coniferous trees. Although the genus has been well-studied in Europe and North America, only fragmentary researches have been carried out on Asian species. In particular, the distribution of Lactarius species in South Korea is poorly understood due to insufficient morphological descriptions and a lack of DNA sequence data. In addition, the misuse of European and North American names has added to confusion regarding the taxonomy of Asian Lactarius species. In this study, the diversity of Lactarius in South Korea was evaluated by employing both morphological and phylogenetic approaches. A multi-locus phylogenetic analysis of 729 Lactarius specimens collected between 1960 and 2017 was performed using the internal transcribed spacer (ITS) region, partial nuclear ribosomal large subunit (nrLSU), partial second largest subunit of RNA polymerase II (rpb2), and minichromosome maintenance complex component 7 (mcm7). 49 Lactarius species were identified in three Lactarius subgenera: L. subg. Russularia (17 spp.), L. subg. Lactarius (22 spp.), and L. subg. Plinthogalus (10 spp.). Among them, 28 Lactarius species were identified as new to science, while just 17 were previously described Lactarius species. Four of the taxa remain un-named due to paucity of materials. A key to Korean Lactarius species, molecular phylogenies, a summary of diversity, and detailed description are provided.
