for growing the larger Pleurotus. At least in my limited experience. I just tossed my last bag of Pleurotus into my compost pile to hopefully grow through a little more before the myriad insect/bugs return it to soil. Odd thing: takes 7 years to break down a Douglas-fir needle here in Oregon, but takes less than 2 years to eat it by fungi. AND you get these neat little mushrooms, too!

Damn you Herb :) I really need to work on my tree ID skills.

God Bless

This was growing about 20’ from a large creek.

The P. ostreatus that I find here in the south are always a darker color, they also have a lavender hue to the spore print.

We find larger material here in Oregon.

Pleurotus ostreatus very common to 1.5 feet across, especially on Bigleaf maple and Red alder, but also on other hardwoods, especially if they have fallen across a creek and have constant available humidity nearby.

Along the Columbia River an even larger species, with individual caps up to 20 inches across growing typically on old-growth Black cottonwood, but sometimes with willow, is found. Am calling that P. columbianum, as I have never seen P. ostreatus that reaches that size. Sometimes large clumps form 30-50 feet up a Black cottonwood that is 5 feet diameter at breast height.
