Difficult question since if it really was 28g wet that should equate to some sort of a trip, its not a superbly low dose or anything.
Personally I think he should check his scales, don't eat heavily before eating the shrooms, if they are wet and not freshly picked store somewhere like a refridgerator ina paper bag.
Sometimes these things happen but likely noone is going to have the killer reason why he should not have tripped. I would be cautious about increasing that dose thinking that that is a good idea. If he could test them on somebody else aswell he would probably have a bit better idea as to whether it was the shrooms or himself. I am assuming that his source can be trusted of course to give some to a friend.
