The conidial (asexual) form of a Nectria sp fungus, probably Nectria cinnabarina, growing on twig.
It yielded these spores (magnification x600, field width 86um):
These are about 8.5x2.5um which agrees with the 5-10(-12) x 1.5-3 µm given for the conidiospores of N. cinnabarina given on this page at Mycobank.
