is classified in Nectria subg. Dialonectria SACC.(SAMUELS & al., 1991). Species in this group are characterized by
having superficial, usually smooth, red perithecia the wall of which
is less than 25 urn wide.
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
The anamoph, sTilbella aciculosa (ELLIS & EVERHART) SEIFERT have Conidia ellipsoidal-fusiform5—7(-9) x 2.5-3 microns.
This fungi was reported in Panama and cta RIca by SEifert. in 1985; SEIFERT, K.A. (1985). A monograph of
Stilbella and some allied hyphomycetes. - Stud.Mycol. 27: 1-235.

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
