a new species of lactifluus russulales agaricomycetes from the brazilian caatinga semiarid region
ISSN: 0028-825X, 2019Co-Authors: Mariana C A Sa, Annemieke Verbeken, Lynn Delgat, Marcelo A Sulzbacher, Iuri Goulart Baseia, Felipe WartchowAbstract:Lactifluus (Russulaceae) is a genus of ectomycorrhizal fungi, comprising mostly tropical milkcaps with more than 150 described species. In Brazil 24 milkcap species are known, but only three of these are described from the north-eastern region. The north east of Brazil is composed of different types of habitats, namely Atlantic Forest, part of the Cerrado ecoregions and the Caatinga Domain. From the semiarid Caatinga Domain, Lf. caatingae is described in this paper as a new species, using morphological and molecular data. The new species is characterised by the rusty brown to brownish orange basidiomes, subglobose to broadly ellipsoid, rarely globose basidiospores with verrucose ornamentation composed of warts up to 0.6 mu m, that are interconnected by fine lines forming a complete reticulum, and the lampropalisade structure of the pileipellis. Phylogenetic analysis shows that Lf. caatingae belongs to L. subg. Lactariopsis, more specifically to an unnamed clade containing exclusively Neotropical representatives.

Novel diversity in Lactifluus section Gerardii from Asia: five new species with pleurotoid or small agaricoid basidiocarps
2018Co-Authors: Eske De Crop, Jorinde Nuytinck, Felix Hampe, Komsit Wisitrassameewong, Dirk Stubbe, Annemieke VerbekenAbstract:The ectomycorrhizal milkcap genus Lactifluus (Russulaceae) is commonly found in tropical and subtropical forests of Southeast Asia. During several sampling expeditions in Thailand, multiple collections of Lactifluus (Lf.) species with pleurotoid or small agaricoid basidiocarps were found. A molecular study was combined with a morphological study, in which the collections were compared with herbarium material. The molecular study indicated that four Thai collections belonged to undescribed species within Lactifluus section Gerardii, as was also the case for herbarium collections of a pleurotoid species from Nepal. One other collection from Thailand appeared closely related to Lf. uyedae, known only from Japan. Five species are described as new in the genus: Lf. auriculiformis, Lf. gerardiellus, Lf. bhandaryi, Lf. pulchrellus, and Lf. raspei.

lactarius subgenus russularia Russulaceae in south east asia 3 new diversity in thailand and vietnam
Phytotaxa, 2015Co-Authors: Komsit Wisitrassameewong, Jorinde Nuytinck, Felix Hampe, Kevin D Hyde, Eske De Crop, Annemieke VerbekenAbstract:Lactarius subgenus Russularia is a dominant group of milkcaps in Southeast Asia. This paper reveals the large diversity of the subgenus, with eight new species and one known species being described from montane evergreen and coniferous forests. All new species are supported by both morphological and molecular data, the latter using Maximum likelihood and Bayesian analysis based on the ITS region. Complete macro- and micro-morphological descriptions and illustrations are given. A key to the new taxa is provided. Lactarius chichuensis is reported for the first time from Thailand.

Lactarius subgenus Russularia (Russulaceae) in South-East Asia: 2. Species with remarkably small basidiocarps
Phytotaxa, 2014Co-Authors: Komsit Wisitrassameewong, Jorinde Nuytinck, Felix Hampe, Annemieke VerbekenAbstract:This paper is the second in a series of biodiversity papers on Lactarius subgenus Russularia in tropical forests of Southeast Asia. This study is based on extensive mycological exploration, especially in Northern Thailand, during the past ten years. In this paper we consider some species that are characterized by remarkably small basidiocarps i.e. with an average pileus diameter that is smaller than 20 mm. One of the most common species in Northern Thailand with dwarf basidiocarps is L. gracilis , originally described from Japan. We introduce the new species L. crenulatulus , L. perparvus and L. glabrigracilis with morphological descriptions and illustrations. Molecular evidence based on the ITS sequence analysis supports the classification and novel status of the taxa. All species are associated with trees belonging to the Fagaceae. These are the first reported collections of small basidiocarps of L. subg. Russularia in Southeast Asia. In our paper we compare these new species with small basidiocarp with similar representatives from Europe and other Asian regions.

Szaro Current Investigations of Fungal Ectomycorrhizal Communities in the Sierra National Forests Gardes
Humana Press Inc, 2016Co-Authors: Thomas D Bruns, Annette M. Kretzer, Thomas R, Timothy M SzaroAbstract:Progress on two main studies on fungal ectomycorrhizal communities in the Sierra National Forest is discussed. One study examined the short-term effects of ground fire on the ectomycorrhizal community and the other examined the ectomycorrhizal associates of snow plant (Sarcodes sanguinea). In the ground-fire study we found that a large initial reduction in ectomycorrhizal biomass is caused primarily by combustion of the upper organic layers; prefire dominants in the Russulaceae and Thelephoraceae are dramatically reduced; and species at greater depths appear to survive the fire. We speculate that fire causes a short-term increase in species evenness. In the field portion of the Sarcodes study, we found that Sarcodes is specialized on a single mycorrhizal associate, Rhizopogon ellenae; the presence of Sarcodes is associated with dense islands of R. ellenae; R. ellenae appears to be a minor below-ground component of the red fir (Abies magnifica) community in locations near but not immediately adjacent to Sarcodes plants; and the Abies magnifica ectomycorrhizal community is dominated by members of the Russulaceae and Thelephoraceae.

2004 Evidence for mycorrhizal races in a cheating orchid
2015Co-Authors: Lee D. Taylor, Thomas D Bruns, Scott A. HodgesAbstract:Disruptive selection on habitat or host-specificity has contributed to the diversification of several animal groups, especially plant-feeding insects. Photosynthetic plants typically associate with a broad range of mycorrhizal fungi, while non-photosynthetic plants that capture energy from mycorrhizal fungi (‘myco-heterotrophs’) are often specialized towards particular taxa. Sister myco-heterotroph species are often specialized towards different fungal taxa, suggesting rapid evolutionary shifts in specificity. Within-species variation in specificity has not been explored. Here, we tested whether genetic variation for mycorrhizal specificity occurs within the myco-heterotrophic orchid Corallorhiza maculata. Variation across three single-nucleotide polymorphisms revealed six multilocus genotypes across 122 orchids from 30 sites. These orchids were associated with 22 different fungal species distributed across the Russulaceae (ectomycorrhizal basidiomycetes) according to internal-transcribed-spacer sequence analysis. The fungi associated with four out of the six orchid genotypes fell predominantly within distinct subclades of the Russulaceae. This result was supported by Monte Carlo simulation and analyses of molecular variance of fungal sequence diversity. Different orchid genotypes were often found growing in close proximity, but maintained their distinct fungal associations. Similar patterns are characteristic of insect populations diversifying onto multiple hosts. We suggest that diversification and specialization of mycorrhizal associ-ations have contributed to the rapid radiation of the Orchidaceae

Especially, they are important drivers in the carbon cycling and in the organic matter decomposition process in tropical forests. In Colombia the knowledge on diversity of this group is still very poor. Through this work we intend to contribute to this knowledge. The macrofungi diversity was assessed on three different substrates on a 4 ha wet montane forest in the Antioquia province during five months. Forty species of macrofungi (two of them possible new species to science) belonging to 34 genera and 18 families were recorded. Marasmiaceae was the most diverse family with five species followed by Boletaceae, Polyporacea and Russulaceae with four species each one. Hypholoma, Lactarius and Marasmius were the most important genera with three species each one. Auricularia delicata (Fr.) Henn., Xylaria polymorpha (Pers.) Grev. y Ganoderma applanatum (Pers.) Pat. were the most frequently found species. The highest species numbers were growing on dead wood (19 species) and the lowest were recorded on litter (six species)
