Observation 116013: Lentinula edodes (Berk.) Pegler
When: 2012-11-07
No herbarium specimen

Notes: Purchased several shiitake blocks at the last OMS Fall Mushroom Showw, at the end of the show (pd. $5 each for them). Have already harvested about 1.5 pounds from 3 blocks, but was waiting for these mushrooms to get larger.

These space bags were grown inside polypropolene plastic bags with microporous filters (“space bags”), and each block contains approximately 2 liters of wood chips supplemented by 10% bran, with the pH amended with calcium source. These were started by Ed Foy who lead the OMS Cultivation group. He is retiring this year. This has been a good money-maker for OMS, and I, for one, am sad to see him leaving. Ed has provided space bags of Pleurotus ostreatus, Pleurotus pulmonarius, Hericium erinaceus, Pleurotus citrinopilus, Lentinula edodes, and several other species since 1993 when I was president of OMS.


3-inch diameter shiitake (Lentinula edodes) button growing on space bag.
I use a cookie sheet to hold a scant amount of water for the blocks to use. Here are some mushrooms that got too wet.
Wide angle of two blocks. When OMS hosted Paul Stamets about 1997, he showed a block and stated “Each block contains about 1 cent worth of sawdust. What you see fruiting is about $10 worth of mushrooms. Which is moe valuable?”
Close-up of gills. Note serrated edges (saw-toothed) on gill edges.
Scaley stipe and notched gills.
The largest specimen today was this 4-inch diameter specimen. I have cultivated a single 7-inch specimen, on a Quercus palustris limb less than an inch in diameter, just to see if shiitake would grow on smaller-diameter branches. It does.
