I had planted pink muhly grass; ordered them about 10” in height. A week after planting them they had turned brown but are still
standing straight up. The climate right now in NY is mid 80s. Water often' its been about a month and they are still like that not familiar with plant. I was wondering why???

Usually, Spring is the time to plant these to avoid failure to take root. It sounds like the transplant has failed. This can happen due to overwatering, or warm temperatures. You may not know until Spring, whether they are fully dead or not.
