It is certainly true that high temp is stressful to yeast cells. Our
usual maximum restrictive temp is 36*C. I don't think I've done much
with pombe at 37*C. The usual questions: is it dependent upon your
choice of wt strain or the media? If you are transforming, it is
probably safer to select transformants at lower temperature and then
replica plate or restreak to higher temperatures for your assay.
Hope this helps,
