Here in New Sharialand we have three types, Blue Meanies, Orange tops and Liberty caps. These look like the liberty caps that grow in thicker bunches and mostly in the South Island or colder climate. You need more to trip off but the trip is shorter and cleaner with all most zero after effect. Blue meanies being the strongest type, they turn purple when you pic them and have a slight blue color on top Orange top being the most common, they often grow in traffic islands or along the side of highways.
