thermal death for shiitake?
    #11299390 - 10/22/09 03:00 PM (8 years, 1 month ago)

Next week were the logs whitish from mycelium popping out from the inside of the wood, afther a week looks burned out, it seems as it grew pins wich died afther a night under )degrees celsius.

I thought mycelium should survive at low temperature.

Here you have pics of the logs at the moment







Are those black gummie dead pins? Can it recover?

Thanks for help

These look like belonging to a different species. Perhaps some kind of cup fungi or wood ear?

Agreed. They do not appear to be shiitake at all. If they were shiitake then they have been overtaken and consumed by competitor fungi. I have witnessed stunted growth of shiitake from too much heat (~100F) but I was left with basically a dessicated shiitake that was dried exactly as it appeared before it got fried.

Also, I have seen similar competitor fungi on my logs but those logs were nearing end of life. Judging by the condition of the bark on that log you are working with pretty new stock.

The logs are fresh I didn't even needed to soak them before plugging.



What can I do with that? Trow it away as contaminated?

I think I'm victim of a joke, somebody must have sent cultures of a shitty mushroom to the freesporeprint beacause they don''t like their free politics.

Culture was labeled L.Edodes ANNO strain

I spent a lot of work for nothing, I have 10 logs 1.5 meters long with that shit :crazy:

I would expect that Fabio got this culture from Anno and nobody else was involved. What you see there might be just some contaminate fungi growing in the bark, while the shiitake colonizes the rest. How much time passed since inoculation? I would wait at least a year, before I toss those logs.

Your word makes me feel good; maybe I'm a little paranoid.

Logs are half year old

I pm'd Fabio and Anno already

I have a few logs that have those same black/jelly/cup like fungus busting. Just seems to be another fungus that was previously on the logs Definetly not shiitake, you need to wait a year for the 1st flush.

Hi Carsten (PM me, hope you're okay!)
you're right, I received the culture in a wedge from Anno and nobody was involved :smile:

I haven't tested that strain but Anno is Anno :wink:

Of course those aren't shiitake primordia, they seem more like Craterellus cornucopioides.

Is this possible?

Another explanation could be the log was colonized already with this mycelium.

I'm really sorry for you, put those logs in a corner and let us know what happens, and start a new batch of logs (consider the idea to start blocks, logs generally are inoculated in spring).

Fabio

Quote:

Mushrooms are ready for harvest when the edge of the cap (the veil) (Figure 3) breaks free from the stipe. You want the caps to be rounded with the edges curled in when you pick for market. They will continue opening after harvesting. Mushrooms that have their caps fully expanded or flat are considered of much lower quality and will bring a lower price. It is important to cool the mushrooms within one hour of harvest, so you should locate your harvesting area near your cooler and move mushrooms into the cooler as soon as you fill the basket, bag, or other container you are picking into.

Your patience has turned into success Agarico.  :smile:  Soon you'll be enjoying those on a plate.  They look very pretty.  Is the purple from the lighting or are they that color?

At first I thought it was a wax covering pluggin the holes but at a closer looks like the myc had barked over like it does on blocks. They look cool but it took over a year. My blocks produce in two to three months with hella more fruits. But cool nonetheless.  myc

I'm glad it worked out for you.  To answer your original question which you already know by now, shiitake can freeze solid in the log and be fine the following spring.

In fact, my shiitake 75 blocks fruit right into November, when the temperature stays below freezing for days at a time, and then when it warms back up during the day into the 2C to 4C range for a few days, fruits pop out all over. The mushrooms even freeze every night and start growing again the next day.
