I have been messing around with my agar ingredients as of late and doing a lot of transfers. This particular plate contains agar, sawdust, rye dust, malt extract, and a small pinch of gypsum.

I noticed the mycelium is a bit light on growth in the middle and normal on the outside as shown in the photos below.




My question is, is there bacteria effecting the growth causing the odd look or is this normal and I am over reacting? Or, could this caused by my odd agar concoction?

Dont trust any plate that has any color other than white

when dealing with some species* Theres a lot of species that pigment. Theres some species that pigment extremely heavy.
Ps. hoogshagenii for instance can get damn near black on agar.

My first time growing zapotecorum. damn thing kept going super yellow lol. i finally said fuck it and sent it. turned out great. now i see zaps go brown as well.

Looks like tamps. Those rings are strange, no idea what the cause is. Maybe someone else has seen it before and can chime in.
Tamps don't really get rhizomorphic like cubes or some other species.

How do my plates of an isolated P. tampanensis strain on agar look??

Plate 1 has a noticably flatter, paler section extending outwards from the middle, and an outer ring of fluffier mycelium growing pretty uniformly around the perimeter (with the exception of the gap around 4 o'clock). What causes this growth pattern? Is it normal?

Plate 2 has a similar pattern to plate 1, with a patchy secondary ring of fluffier growth in the middle (particularly visible from 7 o'clock to 11 o'clock). Again, is this normal? Why am I not getting the pretty-looking rhizomorphic growth pattern I've seen from other isolated strains on agar?

What's your recipe? That is pretty growth.

Need some agar help here, i recently picked up a zap swab and it looks like its got some myc on here, where would you transfer from?  or is it all contam?

---

I'd transfer as far as possible from that certain contam at the bottom and from whatever that is on the left and middle.

So, top right, that rhizo to the right of the end of where you wrote the word "Zaps." I'd transfer tiny pieces there to several plates, maybe 3 or 4.

If you do that, grow it out and post your best of the 4 once it's grown out to about half this big and get feedback.

I think this will need 2 more transfers at least.
