Gingko Rust

Post by Fungalpunk » Sun Jul 29, 2018 10:55 am

<t>Been a while since I have posted on here so hello again to one and all. The trouble I am having lately is with this black growth on Gingko leaves - a ruddy puzzler indeed.</t> The pictures attached show the fungus on the leaf and a dodgy picture of what I believe to be the spores. The spores measure up to a maximum of 13 * 6 microns. Any pointers would be hunky dory - cheers.

Hi Dave
probably early stage of Bartheletia paradoxa; that is the most frequently seen fungus on this host, though your fungus could possibly show an ascus of something like a Mycosphaerella. See http://coo.fieldofscience.com/2008/11/r ... -host.html. At this stage you probably won't see much that is identifiable, there are other possibilities. Check later in the year . . .

Cheers
Chris

Thank Chris - as ever the font of sound advice - very much appreciated. The trees aren't far away so I will duly keep tabs on what transpires.
