Re : Nectria stilbellae from Panama

Hi Eduardo,
Your fungus looks like Nectria pseudotrichia, what is the size and shape of ascospores?

Re : Nectria stilbellae from Panama

Ok Eduardo,

Are the ascomata changing of color in 3% KOH or lactic acid? if so, what is this coloration?
Moreover, could you please to say what is the size of conidia and provide an image of the ascospores?
