From: How to resolve cryptic species of polypores: an example in Fomes
VOC data exploration by unsupervised PCA analysis of all Fomes inzengae and F. fomentarius samples (232 peaks). Basidiome and pure culture samples are well separated by the second principal component (PC2 12.5%). Separation of F. inzengae from F. fomentarius is more pronounced in pure culture samples than in basidiomes (PC1 22.9%)
