Summary
In a study of ectomycorrhizal diversity in a spruce stand in Switzerland the macroscopically classified ectomycorrhizal morphotypes were characterised molecularly by Restriction Fragment Length Polymorphism (RFLP)-patterns of the internal transcribed spacer (ITS) region. In four different plots characterised by different levels of species diversity a total of eighteen ectomycorrhizal morphotypes were macroscopically classified. The evaluation of similarities between the different plot types revealed a more or less homogenous distribution of morphotypes which stands in contrast to the different grades of fruitbody diversity in these plots. Characterisation by molecular tools resulted in a minimum of twenty-three RFLP-types. Seven pattern-types could be referred to fungal species found as fruitbodies in the spruce stand which represents about one third of all mapped fungal species. Different types of correlation between morphotypes and fungal species were observed: (i) one morphotype represents one species, (ii) one morphotype represents several species, (iii) several morphotypes represent one species and (iv) a combination of (ii) and (iii). A low coincidence between spatial distribution and abundance of molecularly identified morphotypes and mapped fruitbodies could be found. The problems associated with classification of ectomycorrhizas and the significance of above-ground fruitbody pattern for below-ground mycorrhizal pattern is discussed.
