Stacci bottra (sp?)

[Jorge1907]

This is a good site and provides pertienent info.  I'll add that this fungus is
usually not directly pathogenic but effects disease via host response to it's
toxin containing spores.
Your student needs to have someone familiar with the fungus and it's effects do
this testing as the spores rapidly lose viability even tho' their toxins are
fairly stable and effective.  
There are more things in heaven and earth, Horatio,
