Hi Bron!
I do agree with your suggested ID but - because I'm trying to be accurate/sure of ID - I'm not convinced. I don't see why it couldn't be S. longipes instead of S. trapezia... (In Whyte & Anderson's guide, S. longipes is on p.362 & S. trapezia is on p. 363) Distribution range overlaps, judging by leg length is unreliable and I don't think there is a particularly distinctive feature between the two, with quite a bit in the features (colour, colour richness, colour distribution and spottiness of legs etc). From what I've found, the male S. trapezia seems to have quite dark legs, but yours isn't as dark.
It might be more accurate to have it under Sidymella sp? I haven't gone too in-depth with research though on potential revisions which may have laid out specific differences.
