Sure, the red ones are my favorite, but they are usually more expensive. They are hardy too, in fact in the last month one of my red mushrooms has had 3 babies. I also like the watermelon mushrooms, they are green with red stripes (pretty easy to find this kind). Blue shrooms are also really cool, but you will only see the blue under certain lighting (again, these are more expensive). There are some fuzzy mushrooms that seem to be pretty available. The ones I see most commonly are a red/brown but look bright green when under actinics. Let's see, you could get an umbrella mushroom as well. Mine is pretty fun. Not the prettiest but they get huge (10 inches). Let's see, those are my favorites of the hardiest mushrooms. IMO mushrooms look best when you have a variety of types together. HTH
