well, if the veils have torn, yes, pick them.

what went wrong? well not sure.
I have a couple suggestions of possibilities.

lack of water.
your straw log is a pumping station now. pumping the water
it holds into the cells of the developing mushrooms. when the
water runs out, the veils open and the growth cycle begins to halt.
mushrooms need water to grow. straw logs are easy to have
dry out on you. maybe yours dried out on you.

genetics. slim but possible chance. using multispore, which I
assume you are doing, would give you a better shot at varied results.
you could have a strain fruiting that just shoots out small fruits,
but it's more likely a moisture problem.

did you mist the straw log every single day, frequently?
