The Bacteria Associated with Laccaria Laccata Ectomycorrhizas Or Sporocarps: Effect on Symbiosis Establishment on Douglas Fir*
Symbiosis, 9 (1990) 267-273 267 Balaban Publishers, Philadelphia/Rehovot The Bacteria Associated with Laccaria Laccata Ectomycorrhizas or Sporocarps: Effect on Symbiosis Establishment on Douglas Fir* J. GARBA YE, R. DUPONNOIS and J.L. WAHL IN RA, Centre de recherches [orestieres de Nancy, Champenoux, F 54280 Seichamps Abstract A range of bacteria isolated form mycorrhizas and sporocarps of the ectomycorrhizal fungus Laccaria laccata were tested for their effect on ectomycorrhizal development of this fungus on Douglas fir seedlings, both in containers in the glasshouse and in a bare-root nursery. Some of them reduced infection, but some others were very stimulating. These results are discussed from the standpoint of both ecology of mycorrhizal symbioses and forestry practice. Introduction It has been shown on different plant - fungus couples that bacteria present in soil, rhizosphere and mycorrhizas strongly interact with the establishment of ectomycorrhizal symbiosis, with the frequent occurrence of a stimulating effect (Bowen and Theodorou, 1979; Garbaye and Bowen, 1987 and 1989; De Oliveira, 1988; De Oliveira et Garbaye, 1989). Some stimulating ("helper") isolates could be of practical interest for improving mycorrhizal inoculation techniques in forest nurseries. Douglas fir is presently the dominant forest tree used for reforestation in France, and field experiments have shown that the ectomycorrhizal fungus Laccaria laccata, when inoculated to planting stocks in the nursery, stimulates the early growth of Douglas fir in plantations (Le Tacon et al., 1988). Moreover, L. laccata sporocarps always contain bacteria, suggesting that this fungus may be particularly dependent on some associated bacteria for completing its life cycle. Therefore, it is worth exploring the possibilities of using helper bacteria in this system. -

Laccariopsis is morphologically close to these genera but distinguished by a unique combination of features: a Laccaria-like habit (distant, thick, subdecurrent lamellae), viscid pileus and upper stipe, glabrous stipe with a long pseudorhiza connecting with Ammophila and Juniperus roots and incorporating plant debris and sand particles, pileipellis consisting of a loose ixohymeniderm with slender pileocystidia, large and thin- to thick-walled spores and basidia, thin- to slightly thick-walled hymenial cystidia and caulocystidia, and monomitic stipe tissue. Phylogenetic analyses based on a combined ITS-LSU sequence dataset place Laccariopsis close to Gloiocephala and Rhizomarasmius. Key words — Agaricomycetes, Physalacriaceae, /gloiocephala clade, phylogeny, taxonomy Introduction Hydropus mediterraneus was originally described by Pacioni & Lalli (1985) based on collections from Mediterranean dune ecosystems in Central Italy, Sardinia, and Tunisia. Previous collections were misidentified as Laccaria maritima (Theodor.) Singer ex Huhtinen (Dal Savio 1984) due to their laccarioid habit. The generic attribution to Hydropus Kühner ex Singer by Pacioni & Lalli (1985) was due mainly to the presence of reddish watery droplets on young lamellae and sarcodimitic tissue in the stipe (Corner 1966, Singer 1982). -
Why Mushrooms Have Evolved to Be So Promiscuous: Insights from Evolutionary and Ecological Patterns

Pheromone receptor Consistent with a role of mating type in mediating cytoplasmic-nuclear genomic conflict, Agaricomycetes have evolved away from a haploid yeast phase towards hyphal fusions that display reciprocal nuclear migration after mating rather than cytoplasmic fusion. Importantly, the evolution of this mating behavior is precisely timed with the onset of diversification of mating type alleles at the pheromone/receptor mating type loci that are known to control reciprocal nuclear migration during mating. -
Megacollybia (Agaricales)

CATHERINE AIME10, TOLGOR BAU11, TERRY HENKEL12 Abstract The genus Megacollybia, originally proposed for M. (Collybia) platyphylla, has traditional- ly been treated as monotaxic. A phylogenetic reconstruction based on ITS rDNA sequences indicates that several species are involved, with strong phylogeographic signal. Although morphological characters are largely qualitative, examination of basidiomata suggests that specimens included in discrete clades can be distinguished at the species level. On these bases (phylogenetic, morphological), several new taxa are proposed: M. clitocyboidea, M. texensis, M. fusca, M. subfurfuracea, M. rodmani (with f. murina) and M. marginata. Tricholomopsis fallax is transferred to Megacollybia; M. platyphylla remains the type species of the genus but appears to be restricted to Europe, Scandinavia and western and central Russia.

9B Taxonomy to Genus
Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org.

The Effect of Decayed Or Downed Wood on the Structure and Function of Ectomycorrhizal Fungal Communities at a High Elevation Forest
The effect of decayed or downed wood on the structure and function of ectomycorrhizal fungal communities at a high elevation forest by Jennifer Karen Marie Walker B.Sc., The University of Northern British Columbia, 2003 M.Sc., The University of Northern British Columbia, 2006 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The College of Graduate Studies (Biology) THE UNIVERSITY OF BRITISH COLUMBIA (Okanagan) March 2012 !Jennifer Karen Marie Walker, 2012 Abstract Shifts in ectomycorrhizal (ECM) fungal community composition occur after clearcut logging, resulting in the loss of forest-associated fungi and potential ecosystem function. Coarse woody debris (CWD) includes downed wood generated during logging; decayed downed wood is a remnant of the original forest, and important habitat for ECM fungi. Over the medium term, while logs remain hard, it is not known if they influence ECM fungal habitat. I tested for effects of downed wood on ECM fungal communities by examining ECM roots and fungal hyphae of 10-yr-old saplings in CWD retention and removal plots in a subalpine ecosystem. I then tested whether downed and decayed wood provided ECM fungal habitat by planting nonmycorrhizal spruce seedlings in decayed wood, downed wood, and mineral soil microsites in the clearcuts and adjacent forest plots, and harvested them 1 and 2 years later. I tested for differences in the community structure of ECM root tips (Sanger sequencing) among all plots and microsites, and of ECM fungal hyphae (pyrosequencing) in forest microsites. I assayed the activities of eight extracellular enzymes in order to compare community function related to nutrient acquisition. -

Polyozellus Multiplex-An Example of Our Mycological Ignorance. Osprey 37:20-22
20 21 Polyozellus Multiplex - An Example of Our Mycological Ignorance by Andrus Voitk Polyozellus multiplex, the blue (or black) chanterelle, shown in Figure 1, grows as a large cluster of black or very dark bluish-purple fan- shaped leaves, arising out of a wide, common stalk. The sporulating surface, on the outside of each fan, is made up of folds, somewhat resembling thick, forked, decurrent gills. The spore print is white, giving mature specimens a dull bluish-gray appearance on the outside, Figure 1 - Polyozellus multiplex, Stanleyville Trail, contrasting with the shinier blackish purple on Gros Morne National Park, September, 2000. the inside of each leaf. The same trees are still there but this gorgeous ectomycorrhizal mushroom has not been seen in that Classical morphological taxonomy considered location since. I am now aware of three places where Polyozellus to be a relative of the chantarelle with this mushroom has been found to fruit. In 1-5 follow- its fold-like gills, along with the genus Gomphus, up years it has not been found to fruit in any of these whose sporulating surface is virtually identical to places again. that of P. multiplex. Recent DNA studies have left Gomphus as a distant relative of the chanterelle but placed P. multiplex with earth fans, Class Telephorales, Family Telephuraceae. It doesn’t seem to fit readily with either and no doubt the future has more family unrest in store for poor P. multiplex. Among interesting properties of this good edible* is its ability to slow certain cell replication. Animal experiments suggest P. multiplex may, among other things, prevent stomach cancer (1).
