I have some pink spawn which was being expanded out in jars of rye berries and popcorn kernels. There’s been good growth and since a couple weeks ago the jar appeared to be completely colonized (at which time I left one jar sitting and moved another jar to a couple fruiting bags). It’s been sitting on the basement floor since then, but I’ve noticed some pink coloration that seems to have gone throughout the jar, and there seems to be a bit of the pink also in the fruiting bags.
I prepared some jars of blue oyster spawn at the same time, using the same batch of rye and popcorn, and those jars are still snow white. This has me wondering, could I have possibly gotten contamination ONLY in the pink oyster jars while all of the blue oyster jars somehow escaped contamination? Or is this pink color natural for pink oysters? It just seems like an awful big coincidence that only the pink oysters would get contaminated when everything was prepped together in the still-air box and there was definitely cross-exposure between the jars.
Since this is my first batch of oysters I’m just not sure what I should be expecting.
You know, the way the pinning looks inside the bag with the solid spots of bright color and a more milky color surrounding it… that DOES look like what I’ve been seeing in the jar. It’s hard to tell for certain with all the moisture the mycelium seems to be building up but I wonder if small pockets of oxygen might have gotten trapped in the jar which caused an attempt at pinning when the mycelium found them? I’ll try to get a pic here soon, but yeah that is certainly the same color.
