You need an environment where the ambient temps drop a good fifteen degrees at the end of summer.... Fruiting temps for most of our pacific mushrooms are around 55 degrees, but they really need to have a warm spell to preceed it to get reliable fruitings. If Morro bay has hot summers and then dip reliably to that 55 degree mark (or there about) and your humidity rises to over 75% at the same time, then you're probably doing all right. If those conditions are familiar to you, then head out to the cow pastures a week or two after the first real change in weather ( ussusally early to mid September) and look for Ps. Semilenceata, (liberty caps) which are among the most common coastal psilocybe in the pacific US, and go to your suburban garden settings to look for Ps. Cyanescens growing among the wood chips.

Incidentally, there are no "cubies" on the west coast of the US, outside of personally propogated strains in people's basements and well tended back yards.
They are a warm weather species... 'Cubie' is the causual term for Psilocybe CUBENSIS, which is arguably the most common mushroom in the world.... everywhere that is warm and humid... In other words, not the pacific Coast.
