Hey,

the rust fungi on Centaurea are anoying....We need information regarding the germ pores. Are they equatorial placed within the uredospores, or in the upper half of the spores? Do we have mostly 2 or 3 germ pores?

Sorry, distinguishing Puccinia jaceae and P. centaureae is a bit tricky.

Cheers,
Julia

Hello Julia,

Thanks for the response, the pores are difficult to see for me so it will stay unknown. Unfortunate, but i have to live with that.

Mvg, Henk.
