Erysiphales - Spore Sizes for 5 Species
Peter Thompson, 10-09-2012 20:27
Hello Everyone,

I would be very grateful to receive details about the spore sizes for the following five species:

Erysiphe alphitoides / Microsphaera alphitoides
Erysiphe aquilegiae var. ranunculi
Erysiphe heraclei
Erysiphe ulmariae
Erysiphe sordida / Golovinomyces sordidus

I have checked the available information in the Braun 1987 Erysiphales drawings, but they do not contain spore data. 

Thanking you in advance,
Peter.

Hello Chris,

Thank you for the spore sizes. I will now be able to complete the drawings and microscopic data section for the powdery mildews.

My progress has been good, and I am still hoping to have everything ready next month.

Best wishes,
Peter.
