Powdery mildew – 2014

59 species of powdery mildew identified thus far in 2014; from 10 genera and all 5 tribes!

This is an increase from the 34 found in the 2013 season (approximately April – October), from 8 different genera.

This increase is likely due to increased sample numbers and thus can certainly not be attributed to any invasive PMs…yet. You may well notice that some species of PM occur on multiple hosts and some hosts have more than one PM species present.

Unlike last years species list, this year I have included species in order of phylogeny (most newly evolved genera (within the tribe Erysipheae) to oldest/most basal genera (within the tribe Blumerieae).

  2. Good to see the growing list! Are these identities based on a combination of morphology and ITS sequence?
