Stemonitis fusca on Salix logs

Observation - Stemonitis fusca on Salix logs. Description: Rather paler than other examples of this species I've seen, wonder if its just within natural variability or if its a different species. Note there are several species of Stemonitis in UK but not found one that looks more like this specimen than S. fusca
