Figure 1
Statistical Parsimony network based on the 24 most frequent ITS types.
The nodes of the network have been replaced by pie diagrams depicting ITS type sharing by different taxa; taxa which occurred only once or twice all over the network are coloured in grey (light gray 1, dark grey 2); the overall frequency of the ITS types is given within the pie charts.
