[Tastebridge] Oyster Mushroom Status?

WOW!  I wish I lived closer, guys.  That is _really_ beautiful stuff there, and the humidity controller is AWESOME!  The uncooked bags are pinning like crazy, so I guess cooking the bags, at least for this species of oysters grown on recently-used coffee grounds, is not necessary at all.   That might be because the actual use of the coffee grounds was so close to inoculation that the heat was a pasteurization of sorts, which is doubly cool since not only does the coffee shop give you the substrate but also the energy to pasteurize it!   Oh and man that blue is GORGEOUS!  So cool!  We should totally do some pink oysters too.  They don't taste quite as great but they are beautiful.  


By the way, the mushroom fair is coming in December and Alan and I will be at the psilocybin mushroom table.  Alan, unlike myself, is a complete genius at memorizing thousands of mushroom names in Latin and has a knack for identification.  I'm more a grower, though, and can answer questions about growing any mushroom.


Speaking of growing unfortunately my Stipticus bags with the molasses-fermented sawdust are not taking off at all.  After two weeks, there still is absolutely no sign of growth in them, so I have decided to see if this mycelium really does grow at a pH of 4.0 in a new liquid culture.  If it is truly Stipticus, it should grow great in it, at least according to the research papers I am using.  As I did not isolate this culture myself, I can only assume it is, as my friend believes, Stipticus, but there could have been some sort of mistake since he's human as much as I.  So far the 4.0 pH liquid culture is not showing definite signs of growth any more than the bags, although it's only been two days.  If it does grow, though, I will once again try to inoculate the substrate I have used before with it.  And if the liquid culture doesn't grow out at 4.0 pH as it did at 6.0 pH, it's back to the agar plates since I'll have to isolate the mycelium from some
 a few commercial wooden dowels I got that do have stipticus on them because I do not think the plate can be Stipticus if it cannot tolerate the lower pH since that's the approximate pH of the ecological niche this species inhabits in the wild.

Hey everyone,

Just a quick update on the status of our project, and a link to pictures of the first flush coming up on our second batch of oyster mushrooms. The uncooked bags seem to be doing splendidly, given the density of the pinning likely due to the excessive spawning rates.

Check them out!

I came in on Saturday to cut the second batch out of the bags (left a couple in for comparison, but have removed those today) and put them in the fruiting chamber. I also set up the humidistat (thanks, Jake - you rock!), which seems to be doing a great job of regulating the humidity - at least, it claims that humidity remains fairly constant between 90 and 93 % RH, and is using about 75-80% less water. Someone has been awesome and donated a tray of moisture-retaining crystals for the chamber, and since I don't see that they could be doing any harm, I've left them in.

I have a pretty tight schedule this week, so I need to leave early tonight, and won't have time to come back into the city tomorrow, but someone should seriously come by and harvest some of these lovely, tender, new oyster babies!

>>Hope not too many of you showed up in vain on Monday? Roger came in early and did most of the planned clean-out all by himself, and I took the welcome opportunity to stay home and care for my head cold. I did go in this morning to clean out the rest of the chamber, wiped everything with bleach water, re-glued the magnets (the trick is to rub the glue in with the tip of the gun so the plastic melts a little bit) and took a bunch of pictures which I posted here. There was a fine little harvest of beautiful, big oysters as reward.

>>I threw away a block that had spots of grey mold (looked like Botrytis, at least), turned the humidifier back down to lowest setting, replaced the fan with one that wasn't alive (I swear, there was oyster mycelium growing on the caked spore mass!), and checked up on our babies. I discarded one of the second batch of uncooked bags because of green mold contamination, so we need to be pretty wary of this.

>>Roger, the pressure cooked bag I photographed appeared fully colonized on the bottom, too, though I generally see what you mean about there being some invisible lower limit that they seemingly only cross with difficulty.

>>I definitely want to do a third batch of these, though I think it's clear from the experience so far that going to the effort of borrowing extra propane burners and pressure cookers would be a really good idea - the extra time spent on preparation is easily saved by the difference in inoculation rate. However, I don't want to commit to using 40 lbs of spawn, so Roger has promised to make us a  smaller portion - this will take a couple of weeks, so by the time it's ready, we should have some indication of how the fruiting success, and know whether to proceed with coffee or go back to sawdust.

>>Last, but not least: we need to come up with a rotation schedule so that ten humidifier gets refilled at least every second day. I filled it to the top today, but someone needs to go in on Friday and on Sunday to do it again - any volunteers?
