My purp grain has been mixed a time or two and it looks like I now have a reasonably thorough inoculation. I’ve never used this little grain with wedges in bags. Or the no prep in a bag. One bag is either bacterial or just uneven moisture in the grain which is a huge possibility with this method. My Semperviva has done well enough with the supplemented sawdust and coir sub that I believe that’s the way I’ll go with at least one grain bag. Maybe two. I’d like to try a nonsterile eggar to tree waste. My oaks are dropping acorns and I get a lot of them with the lawnmower. Branches in various stages of decomposition falling. Woody topsoil. I think the one that might be bacterial/might just have a wet overcooked bit of grain I’ll set aside for my native ingredients.

While we're waiting for fruits I thought I'd share these pictures of a G.purpuratus grow I did a while back. It's certainly been a rewarding species to work with.

Those are beautiful. Basically everything I did for about 8 weeks was affected by my mystery illness. Even things that seemed to be going well I managed to lose track of or overtend. I have a couple of unrelated things I’m letting attempt to fruit, but I started everything over.

I picked up half pint jars and dropped large wedges from the original germ plates on WBS. 5 jars in total. Feeling much better and more clearheaded. And the smaller spawn jars and more genetics ought to give me more chances on this.

Beautiful work!! How long did those take to fruit? I’ve had a tray in fruit for 9 days.

Thanks, and sorry to hear about your grow Jrotten and that's a good strategy to test numerous cultures especially with wild spores where there's still a ton of genetic diversity.

 

@Celestialexplorer1 I recall seeing knots at 2 weeks. The clusters appear to develop slow at first before rapidly expanding once they reach 1/2" in height. I've done several grows and the following took 2 months to fruit.

They were fruited at lower temps at around 50f which may contribute to the lag. Different genetics so it's hard to say but this lot took by far the longest of all grows. It may even be a different species since taxonomy on Gymnopilus is still in it's infancy and it can be tough to tell species apart even through microscopy.

 

The most prolific flushes I've achieved were with G.dilepis and they also tend to grow larger than other active gyms. They took between 2-3 weeks to fruit after full colonization.

Very good to know and those are some seriously beautiful fruits that’s what I’m growing them for. Did you fruit these all outside?

Yes they are very colorful species. You never quite know how they'll turn out until they fruit. These grows were all fruited indoors in a fridge FC. I photograph my grows outdoors as I find natural lighting makes for better pictures.

Lovely grows! Would you be willing to share more details about your FC? Were these grows all at lower temperatures?

The first grows in small containers were done in a modified mini fridge.

I built a custom replacement door filled with perlite which provided passive humidification and fresh air exchange. It worked well for a number of species but it was more of an artistic concept. I fruited them in the 55-65 range to replicate the natural seasonal temps here.  I originally built the FC to fruit P.subaeruginosa,allenii and other temperate species. In latter experiments I realize gyms are not so sensitive to warmer temps as the caramel cap wood lovers. If one can keep temps around 65-70 they'll still fruit and may do so at even higher temps but I haven't experimented beyond that range so building a fridge FC may not be necessary at all. Even if you do go that route there's much simpler ways to utilize a fridge as a fruiting chamber.

What is that fruiting in there in the picture. Also is there a write up of your FC. I’ve been working on something similar and it would really help.

By the way.. absolutely brilliant

smellitstinknot, did you have any luck with the sect. cyanescens species in there? I've been thinking of putting together a cold fruiting chamber at some point in the next year with the same goal; I was thinking of using a chest freezer with a temperature controller. Your setup looks quite nice!

I had begun to make this super complicated chest FC made out of insulation board but ended up making it too big for the thermoelectric cooling unit but I made a smaller one out of a small chest cooler that was temp controlled down to 40f. I had an ovoid bag in ther for awhile at 55f but ended up expanding it and making that 7lb bag out of it and it’s now consolidating in a 18Qt tub.

The mushrooms you see in the fridge pics are Psilocybe alutacea, a close relative of P.semilanceata.

@newmoon are you referring to the sect.zapotecorum species? It's a tropical species so I haven't bothered with the fridge FC. I have managed to fruit the species in a tub of perlite with the cracked lifted at room temp (70-75) and they took over a month to pin. The closest species to P.cyanescens I've fruited indoors is a cake of P.subaeruginosa.

I have a sub shoebox that’s looking great right now planning on trying a week of 55f and then room temp fruiting. Maybe I should have done that with the gyms.

Awesome! I was wondering about the subaeruginosa, allenii, etc. Very nice success with the subs.
