Hi! One more found on old Populus tremula log in O
The sporodochia are rounded to oblong, to 0,4 × 0,7 mm, pulvinate, setose. In wet condition the slimy mass of conidia is light grey, drying to darker gray and finally dark brown. It has two kinds of setae, the acuminate type is up to at least 300 µm long, very dark, opaque, with at least some septa below. The other type with a rounded apex is up to 170 µm, smokey brown with a lighter apex, no septa. Both types have a bi- or multifurcate base. The excipulum has light brown cylindrical hairs. The conidia are 10.3 - 12.5 × 2.3 - 2.6 µm (excl. appendages), guttulate, with a 5-10 µm long filiform appendage at each end. Conidiogenous cells in the last photo.
My best guess is something in Koorchaloma but i can't find a matching species. Are there better suggestions?
