Auto-SummaryThis post shares the author's first experience with mushroom cultivation, specifically Golden Teacher, Mazatapec, and Penis Envy using MSS Pastyplates. The author details their transfer process, including challenges with sterilization and identifying mycelium versus mold. They discuss the growth patterns of each variety, noting that Golden Teacher was slow to start but consistent, while Mazatapec had one contaminated plate and one aggressive grower. Penis Envy showed the most consistent growth, with the author taking three transfers from the most aggressive plate. The author also mentions two contaminated and two non-growing plates, attributing some issues to their sterile methods and handling of the plates. They express gratitude for any advice and input from experienced forum members.
I hope it's ok for me to post this here, I'm an utter noob and I just completed my first transfers from MSS Pastyplates. I'm hoping to get some feedback on whether or not I made correct choices and where I could have done better for future reference.
These were all inoculated on 9/28 and transfers took place today (10/10). I know I should have made the T1 transfers from MSS plates at the earliest sign of mycelium, but it is what it is at this point. It was so tomentose I wasn't sure what to transfer or whether it was mycelium or mold (plus I was just nervous I was going to screw it up). I used a pre-mixed MEA that I bought on Amazon plus some red food coloring, and I'm wondering if the nutrient level of the pre-mix is why my mycelium was so cottony. The Golden Teacher mycelium was probably at least 8mm thick!
I also noticed while reviewing this post that it looks like I took these pictures with my hand and phone hovering over the open plate - I did not. I'm dumb, but I'm not quite that dumb. The plates were inside my SAB, my phone was outside of it. There was a sheet of Lexan between them. Obviously, you cannot take a decent picture of Pastyplate mycelium with the lid on they way you can with proper petris. I just wanted to mention that before someone called me out for holding my hand over the open plates. I did try to avoid letting my hand ever cross over the plates.
-------------------------------------------------
So up first was Golden Teacher. I had one plate that just never kicked off. It didn't contam, it just did nothing. The other plate was a little slow to kick off, but then turned into what seemed like a very consistent growth pattern. Here is the before and after so you can see what I transferred:

I know it looks like I took the cuts with a rusty machete while blindfolded, but I swear it was a flame-sterilized scalpel with a new blade. I just suck at using it so far. I had a hard time choosing what to transfer, so I just took wedges of what seemed like the most aggressive myc.
-------------------------------------------------
Next up was Mazatapec. I had one contam on me so I tossed it (contam pics at end for advice) and one made it. As you can see, I had a little control issue with the syringe here, and let several drops go:

Again, I just took what seemed like the most aggressive mycelium for my two transfers.
-------------------------------------------------
Lastly, we have Penis Envy. One of these was actually the first plates to show growth, and it remained the most aggressive. It was also the only of the four varieties I inoculated two plates each with in which neither plate contaminated and both produced mycelium. The second plate, while it produced nice looking mycelium, wasn't nearly as aggressive as the first so I wound up leaving it untouched and instead took three transfers from the first plate. The first one (yeah, I got a little spastic with the syringe here, too):

And here is the one I didn't transfer from:

-------------------------------------------------
I also inoculated two plates with PF Classic, but one contaminated and the other never showed signs of any life. I inoculated two more plates from the MSS tonight, fingers crossed - otherwise, I'm going to start worrying about the syringe and the 6 PF Tek jars I also nocced with it.
-------------------------------------------------
I'm going to include pics of the two I tossed for contamination, just for confirmation. This first one I'm sure was bad, the contamination showed up in under 48 hours. Any thoughts on what it was?:

The next one showed up around 72 hours, and at first I thought it could be mycelium, but ultimately decided it was too soon and too close to the edge, and must be mold, so I tossed it. Do you think I was right, or did I toss mycelium?:

-------------------------------------------------
So, in total, I had two contaminate and two show no growth out of 8 plates. Not a great start, but at least I got something for my efforts.
I can only assume that I didn't dribble enough out of the syringe into my waste bowl after flame sterilizing the needle and before inoculating the plates for the two that showed no signs of life. I was inoculating 6 PF Tek jars per variety, flaming the needle every two jars, then flaming it again before noccing the plates. I must have nocced two of them with BBQ'd spores.
As for the contamination, I'm sure my (not very) sterile method sucks. It will hopefully get better. I may also have contaminated them flailing the plates around in my SAB trying to shake the condensation out of them. I'll know from now on to make up my Pastyplates at least 5 days ahead of needing them (and don't put them in the fridge!) so the condensation can evaporate a little.
Again, I hope this isn't the wrong place to post this, but since it seems like some of the board regulars frequent this thread, I was hoping to get some experienced input on whether I should have made different decisions on where I took my transfers. Any and all input/advice/criticism is welcome, wanted and appreciated!
[Edit to add: I have kept all of the original plates I transferred from, so if you do see something that you think I really missed the boat on, please let me know. I can still transfer it! Assuming I didn't contaminate the plates, of course.]
