I think 70% alcohol is 70% alcohol. Just add some water to the ethanol to get the 70% ratio?

The 50% will probably work fine. It will just not evaporate as fast, and that is what we want in mycology and why 70% is recommended over higher %. When you are wiping down a SAB or Jars you don't want the alcohol to evaporate off immediately, the water slows the evaporation allowing the alcohol more time to penetrate. When alcohol is mixed with water it also breaks down the surface tension of the water, so this could also be another factor why pure alcohol is not recommended.
I personally use 99.5+% Isopropyl that I get in 5 gal jugs and dilute it with distilled water to the concentration I want, depending on the application. I use it for a lot more than just mycology.
What ethyl do you have? Ethyl is better for drinking and using for extractions. If using ethyl for extraction, use the highest proof you can get. The highest proof I can get in my local liquor shop is 96%. Its a Polish rectified spirit:
