After a dry summer in Maryland, we woke up one day with a major shiitake bloom. These mushrooms are very good to eat and were as much as 9 inches in diameter. These logs were inoculated two years before and had bloomed once before, about a year earlier. See also the bright red and yellow reshi mushrooms which were grown on a sawdust mixture. Reshi is an excellent immune system enhancer noted for helping AIDS victims.
