Parasol Mushrooms

There are a number of different Parasol mushrooms, some of which are edible and some of which are poisonous.
These could be Macrlepiota rhacodes in which case they are apparently very tasty but they also look like Lepiota. There are a number of species of these some of which can be very poisonous.
Whatever they are they are very pretty to look at and I shall leave them growing in the forest and buy my mushrooms from the supermarket.
