Field ectomycorrhizas of Cortinarius helodes Moser, Matheny & Daniele (sp. nov) and Gyrodon monticola Sing. on Alnus acuminata Kunth (Andean alder, aliso del cerro) are described based on morphological and anatomical features. Ectomycorrhizal roots were sampled beneath fruitbodies of C. helodes and G. monticola from two homogeneous A. acuminata forest sites located in Tucuman and Catamarca Provinces in Argentina. C. helodes ectomycorrhizas showed a thick white to beige mantle exuding a milky juice when injured, were bluish toward the apex, and had hyphal strands in the mantle. G. monticola ectomycorrhizas showed some conspicuous features like highly differentiated rhizomorphs, inflated brown cells on the mantle surface, and hyaline and brown emanating hyphae with dolipores. Restriction fragment length polymorphism analysis of the nuclear rDNA internal transcribed spacer provided a distinctive profile for each of the collections of fruitbodies and the mycorrhizal morphotypes.

    ABSTRACT: The ectomycorrhizal (EcM) symbiosis involves a large number of plant and fungal taxa worldwide. During studies on EcM diversity, numerous misidentifications, and contradictory reports on EcM status have been published. This review aims to: (1) critically assess the current knowledge of the fungi involved in the EcM by integrating data from axenic synthesis trials, anatomical, molecular, and isotope studies; (2) group these taxa into monophyletic lineages based on molecular sequence data and published phylogenies; (3) investigate the trophic status of sister taxa to EcM lineages; (4) highlight other potentially EcM taxa that lack both information on EcM status and DNA sequence data; (5) recover the main distribution patterns of the EcM fungal lineages in the world. Based on critically examining original reports, EcM lifestyle is proven in 162 fungal genera that are supplemented by two genera based on isotopic evidence and 52 genera based on phylogenetic data. Additionally, 33 genera are highlighted as potentially EcM based on habitat, although their EcM records and DNA sequence data are lacking. Molecular phylogenetic and identification studies suggest that EcM symbiosis has arisen independently and persisted at least 66 times in fungi, in the Basidiomycota, Ascomycota, and Zygomycota. The orders Pezizales, Agaricales, Helotiales, Boletales, and Cantharellales include the largest number of EcM fungal lineages. Regular updates of the EcM lineages and genera therein can be found at the UNITE homepage . The vast majority of EcM fungi evolved from humus and wood saprotrophic ancestors without any obvious reversals. Herbarium records from 11 major biogeographic regions revealed three main patterns in distribution of EcM lineages: (1) Austral; (2) Panglobal; (3) Holarctic (with or without some reports from the Austral or tropical realms). The holarctic regions host the largest number of EcM lineages; none are restricted to a tropical distribution with Dipterocarpaceae and Caesalpiniaceae hosts. We caution that EcM-dominated habitats and hosts in South America, Southeast Asia, Africa, and Australia remain undersampled relative to the north temperate regions. In conclusion, EcM fungi are phylogenetically highly diverse, and molecular surveys particularly in tropical and south temperate habitats are likely to supplement to the present figures. Due to great risk of contamination, future reports on EcM status of previously unstudied taxa should integrate molecular identification tools with axenic synthesis experiments, detailed morphological descriptions, and/or stable isotope investigations. We believe that the introduced lineage concept facilitates design of biogeographical studies and improves our understanding about phylogenetic structure of EcM fungal communities.

    • "The mycorrhizal status of certain families and genera is varied; it is important to evaluate mycorrhizas in terms of soil characteristics and the mycorrhizal status of the dominant species, and thus, the inoculum that prevails in any particular habitat [2] [25] [26]. Attention has been focused on the mycorrhizas of forests in the humid tropics [11] [12] [50] [51] [60] [72] [73] [77], but there is little information concerning the distribution and abundance of these types of symbioses in the Yungas [3] [4] [5] [6] [7] [8]. Little is known of this endangered ecosystem and an urgent call is made for its conservation. "

    ABSTRACT: In Argentina, the Yungas forests are among the ecosystems most affected by human activity, with loss of biodiversity. To assess the mycorrhizal status in these ecosystems, the roots of 41 native plant species belonging to 25 families were collected throughout the year from two sites of the Yungas forests. Roots were washed and stained to study the presence of arbuscular mycorrhizas (AM). Morphological types of arbuscular mycorrhizas(Aru m and Pari s-type) and colonization patterns were identified and photographed. All plants presented AM colonization. The AMcolonization patterns varied from single intracellular aseptate hyphae, coils, appresoria, to vesicles and/or arbuscules. Among the species studied, the Pari s-type colonization showed to be dominant. Results confirmed that AM hosts are predominant in the Yungas of South American forests.

    • "From studies on ectomycorrhizae of alder species in North America, Europe and South America, it is known that ectomycorrhizal symbionts are dominant on Alnus sp. roots [9] [10] [31] [45] [46]. A. acuminata is associated with a number of ECM fungi belonging to the genera Russula, Lactarius, Inocybe, Laccaria, Cortinarius, Naucoria, Alpova [32] [47] [50]. Ectomycorrhizas are relatively specialized with a distinctive morphology and A. Becerra et al. "

    ABSTRACT: The objective of this study was to determine patterns of ECM colonization of Andean alder at two natural forests in relation to soil parameters at two different seasons (autumn and spring). The soil parameters studied were field capacity, pH, electrical conductivity, available P, total N and organic matter. Twelve ECM morphotypes were found on A. acuminata roots. The ECM colonization varied among soil types and was affected positively by electrical conductivity. Multiple regression relationships among ECM colonization and edaphic properties variables showed no significant differences at two seasons and among soil types with respect to morphotype diversity values. Positive correlations were found between three morphotypes (Cortinarius tucumanensis, Gyrodon monticola and Russula alnijorrulensis) and soil types and two other morphotypes (Naucoria escharoides and Lactarius sp.) between two seasons. Results of this study provide evidence that ECM colonization of A. acuminata is affected by some chemical edaphic parameters and indicate that some ECM morphotypes are sensitive to changes in seasonality and soil parameters.
