They worshiped Mary as if she were God. What specifically they attributed to her - other than divinity - is not really known.
“So anyone who ascribes to Mary that which belongs to God is a heretic right ?”
Except for those things God shares with the saints, yes.
“(BTW it was this group that Mohamed got the idea that the Trinity was The Father , The Son and Mary from and parts their gnostic gospels are quoted in the Koran)”
False. There is no credible evidence Muhammad’s (it’s not “Mohamed”) knowledge of Christianity was gained from Collyridians rather than other heretics. No historian has documented any actual evidence that Muhammad knew any Collyridians. If some Muslims, including Muhammad, believed Mary was part of the Trinity it would simply be because they were former polytheists who would be familiar with tritheistic beliefs rather than the Christian belief in the Trinity. Some ignorant people put forward 5:116 of the Qur’an in some vain attempt to prove what you have just said. The problem is that 5:116 says nothing about the Trinity, nor Collyridians, nor Catholics. All it does is show that Muslims were as stupid as modern anti-Catholic Protestants in that regard.
“Say if you gave Mary titles and duties that actually belong to the Holy Spirit that would make you a heretic right ?”
Not if those are titles and duties the Holy Spirit shares with saints, no. Both Jesus and Satan are called a morning star. The fact that they are both called something similar doesn’t confuse me. I don’t confuse one for the other. I also don’t confuse Mary and God no matter what traditional title is used or traditional duty is described.
