From the information you give the hairs are too long and the spores too narrow for S kerguelensis. There are a few species which key out relatively easily but to stand any real chance of differentiating between many of the others Lactophenol Cotton Blue on the mature (ejected) spores is essential.

Hairs septate, dark brown, with pointed tips, mostly simple (saw 1-2 bifurcate bases), up to 800 × 25um. Asci 8 spored. Ascospores smooth @ 1600x (did not use stain) but with little ‘balls’ inside, exactly as seen here: http://calphotos.berkeley.edu/...
ellipsoid, 18-23 × 10-12um
Paraphyses clavate/septate at ends, appearing filled with yellow-orange content?

Do you have access to Schumacher’s “The genus Scutellinia (Pyronemataceae)”? If so could you share? e-mail: jamesveitch17@gmail.com

Let me know if you need measurements for asci, paraphyses, etc.

Have you photos of the details on which you base the id or at least some of your measurements?
