Dry looking mycelium turned blurry now with little spots

Hello everyone, i'm trying my first mushroom grow. They are in incubation at the moment. i've been noticing some blurry mycelium inside two jars. Before this happen one of the jars had a spot that looked really dry; I was incubating with a light bulb (no light to the mycelium, they are in a box separate from the light but still get heat) so I thought they were getting dry because it was really hot, around 35 deg C. After the first two weeks I got my thermometer and adjusted the temp to 29c.
This is only two jars out of six, I'm worry about this two jars because the other three have beautiful mycelium that looks really solid.
This two pictures are of the allegedly contaminated jars, one of them is starting to get some black spots. Since the spots just started over the weekend I decided to post here, I have looked over the possible contaminants info:
http://www.shroomery.org/11336/Contamination
The how do i tell contaminanted mycelium from healthy ones and the common contaminants, but since this is the first time, is not something like green mold that would be easy to tell apart, and I really don't know.
Here are the pictures, I know I mention two jars but this are all the same jar, you can see part of the second jar on the last picture.
This is a picture of when I first noticed this, here I was still using the bulb to heat them. This was about almost two weeks in incubation at 35 Deg C.

These three remaining pictures are of today; This is what I'm seeing as blurry and on the bottom of the jar there are some black spots, I don't know if it is of the substrate or infection.

Any advice appreciated, thanks.

35 is way yoo hot.. hell, 29 is still to hot. Room temperature is fine. The growth will be a LITTLE slower but your chances of contamination will be much lower as well! As for the two jars, if yoi doubt em, toss em. You could give them a smell. Or just watch and see what happens.

alright, thanks man! yeah... I have them in a box in my closet and norm temp is around 29 it goes down to 27-28 at night. I'll keep those jars separate and see how it develops, no smell so far.

I doubt mushroom mycelium can even grow at 35C, a lot of molds can't even grow at that. It's not hot enough to kill the mycelium though

It has been ultra slow... I mean it's almost over a month and there are two jars which are half done, the other 4 are around 1/4 =/, after some time the mycelium growth stopped at 35C. After temp was adjusted I could see the growth overnight. They have grown twice as fast in half the time at 29c than at 35C.
At 35c the two jars that are currently 1/2 way done got up to like 1/4 in a month, the others I could only see a little spot mycelium I really thought they were not going to grow.

Your not giving it a chance -you want that jar to finish ASAP. Contams are 99% already there- when we sterilize we only kill a % of them - just a quick jab to we can give our spores a chance to start - a pressure cooker and some rye or milo would change your whole world. Myc wont "die" at cold temps like it does at overly hot temps. Rule of thumb i use - If its too cold for you naked to chill where your jars are, then its too cold. (freezing is different ). but it will stall out - causing a window of vulnerability for the contams that have been germinating since you spawned to get foothold.
