found on a twig, probably Populus

conidiomata, sporodochial, erumpant, orange when dry (Picture 2), pale pinkish when fresh (Picture 4), with a darker short, stout stem. Conidiophore arising from somwhat stromatic cells of textura angularis. Conidiophore, long, often curved, hyaline, conidiogenous cells produced pleurogenously, as small strongly apically curved phialides, usually found below a conidiophore septum. Conidia, hyaline, aseptate, smooth, somewhat variable in shape and occasionally slightly sinuous, allantoid or constricted at the center. Conidia measure 5.5 - 7.5 µm x 1.8 - 2.3 µm (avg = 6.6 x 2.1).

This relatively common and distinct species here because of its coloration, large size and pleurogenous conidiogenous cells, it often grow on twigs and small branches. It also, often have a teleomorph associated with it, but it was not seen in this collection.

Nectria dematiosa is apparently similar but without a stout stem, while N. canadensis is decidedly synnematous and occur on elm.
