Nectria stilbellae is distinguished primarilyby its anamorph and is most closely related to
N. consors (SAMUELS,1977),
N. camelliae (SHIPTON) BOESEWINKEL (SHIPTON, 1979; BOF.SEWINKEL,1982), and the
Nectria species that haveDescription ettsils in: http://www.landesmuseum.at/pdf_frei_remote/Sydowia_43_0249-0263.pdf

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