After Ascitendus which I saw is quite frequent in the US here something similar with 1-septate dark brown spores, from Massachusetts. It also grew together with Orbilia luteorubella, so in a similar wet habitat, on unidentified deciduous wood.Don Pfister, the collector, named it "?Amphisphaeria". The photos I made today, therefore nothing is alive anymore (collection date Oct. 1994).
