Hard to tell. It should be further along than that at two weeks though. What type of bag/filter/container is it? Not a good idea to open the bag/container to take a picture. Very efficient way to introduce green in a hurry.

I dont think green is such a problem with hardwood loving species...
What kind of woodchips are those? Is there anything else in the substrate? How did you prepare them?

thanks for your replies I am totally new to cultivation of mushrooms and this is my first trial - so excuse me if I have done mistakes 
so regarding to substrate - i prepared the following mixture (3KG)
1% chalk 25% straw 75% wood shavings (i have no idea from which wood it was taken, the package only says 100% natural wood - I bought it for €2 only so I won't be surprised if it is softwood) 1 cup sugar
I've wet everything and then placed them for 20 minute in the microwave
after it cooled, I added 60 grams of Shiitake spawn and mixed it well
I placed it in a plastic container and covered it with a bag on top
Now it has been there for 2 weeks

I am noticing that most of the growth is on the straw and little on the wood shavings

I have never used sugar in any of my grows. That seems awfully rich. A cup of bran for shiitake in 3kg would be pushing it. If you don't have a pressure cooker try the shiitake with just the first three ingredients and pasteurize it. Shiitake will need some type of filter for air exchange too. It won't grow well without a bit of air.

thanks for your comment i added sugar to compensate for the lack of nutrients in case the shavings are from soft wood (from the price I take it that it is soft)
I did not seal the container - it is loosely closed with a bag so there is an exchange of air (no filter though but so far doesn't seem that i have a contamination)

sugar. no. Don't add it! A little whole grain bran will go a long way as previously stated.
To me the shavings look like pine. Conifer trees have anti microbial/anti fungal properties to them.
I would try again and try to find a place to obtain oak and other hardwood chips/shavings. Sawmills. tree trimmer folks. arborists. the local utility companies. all good sources for wood chips.

There is nothing wrong with adding sugar as a supplement. Sometimes i do it for lions mane or king oysters too; it is not an uncommon ingredient in a sawdust substrate mix.

Definitely not. Shitakes need a fairly fresh hardwood substrate. As for the sugar...never tried that. We always used rye & wheat bran as a source of glucose.

Trichoderma can infect blocks if you have not enough FAE and too much moisture. It looked like the block was really dry though.

I never knew about adding sugar ever. I only cultivate shiitake on plugged logs.
The japanese use 2-3kg sugar per 100kg of woodchips. http://www.alohamedicinals.com/book2/chapter-4-03.pdf

the few instructions that i got say that it is okay to use softwood (instead of hardwood) but then you have to supplement it with other nutrients e.g. sugar thus why I added the sugar

It is getting more evident that almost all the growth that i am having is on the straw and little to none on the wood shavings - do you think it would be a good idea if next time i try to grow it on 100% straw?

This shiitake was grown on plain, pasteurized unsupplemented straw.

It is also an example of less pins makes for bigger fruits!

Do you keep opening the container to check / take pictures?
