FIGURE 2 in New sources of taxonomic information for earthstars (Geastrum, Geastraceae, Basidiomycota): phenoloxidases and rhizomorph crystals
FIGURE 2. Phenograms of the G. lageniforme s.l., G. saccatum s.l., and G. triplex s.l. samples studied, obtained from phenetic analyses based on distance matrices. A. Classical morphological traits phenogram (analysis 5). B. Phenogram of the combined dataset from phenoloxidases spot tests and rhizomorph features matrices (analysis 6). Numbers above branches are BS values from Fitch- Margoliash based algorithm and Neighbour-Joining analyses, and numbers below branches are AU p-values from clustering analyses based on Gower's distance matrices. Branches are indicated in bold when at least two of the three branch supports are significant (BS ≥ 70%, AU ≥ 95%).
