Last week the question was:  What is on this cedar tree?

This is a cedar apple rust gall.  This is a type of fungi that requires two different hosts to complete it’s life cycle.  As the name suggests, it requires a member Juniperus genus and a member of the apple family.  The bright orange growths are covered in spores waiting to be dispersed by the wind.  This is a fairly common disease, though a relatively minor issue.  For more info, take a look at this publication.

 

Here is this week’s question:  What is happening at the base of this wheat leaf?  It may be a little difficult to see.
