I finally transplanted the pile about five days ago, well, a couple of wheelbarrow loads. It was bone dry for a week, watered it some, covered it and today I looked and it was full of pins. I so want to grow this strain because it is so hardy but I'm not sure it really is edible. Can you check it out Mycelio on this please.

For me, it is definitely not Leucoagaricus americanus. L.a. should have a fat stem, while yours are thin. I fully agree with Alan Rockefeller, thinking about a Chlorophyllum species, but I can't say which species. Please add more pictures, like young, developing mushrooms. Shape and color of the closed cap might be enlightening, also the ring of a mature mushroom. Check, if the ring can be moved up and down freely.
Else Vellinga is the current leading expert regarding the genus Chlorophyllum. According to her work on Australian species, it might be C. hortense, but I am not sure what else can be found in the Philippines. http://nature.berkeley.edu/brunslab/papers/vellinga2003_aust.pdf
Maybe you can repeat your Meixner test with some mushroom that definitely contains Amanitines, just to get sure, your method works?

Did you clone the parasols to cardboard or on agar? Very interesting thread!

I only cloned them once on substrate, but as parasol mycelium seems to grow strong on almost everything, I would expect cardboard to work fine.
When I found the last ones, I dropped small tissue samples from the upper and lower end of the stem into tiny jars with a mixture of compost/hay/spent oyster substrate/rice/WBS, which I just sterilized for other experiments. From 8 jars, 2 showed no growth and 1 turned green after a week.

Thanks Carsten for taking time. I added more photos from my patch on this thread. The ring is movable in the mature specimens. Yes I am looking for a mushroom that will react to the Meixner test. Your last pic looks exactly like the mycellia on my patch. Is that procera or rhacodes? Are you going to fruit it? They really seem to prefer the dry side. I noticed the wet patches on my patch stalled.

You're welcome! Please add the ring information to the other thread, it is an important detail for IDing Macrolepiota or Chlorophyllum. Also add if the ring is double edged at the outside. It is not clearly visible in your first post over there. I just read that there are Macrolepiota species, which bruise redish brown too, hopefully our experts in the hunting forum are already finding out which ones.
All three pictures above show Macrolepiota procera. I will try to fruit it, but chances are close to zero. The mycelium develops these rhizomorphs after a couple of days. Mycelium of Chlorophyllum rhacodes showed identical rhizomorphs, but less and later.

Why so? If it's anything near to what I have, it looks like a crazy grower and fruiter.

I wish M. procera would fruit as easy as the mushrooms you have there.
I am only aware of two reported indoor fruitings:
'Characterization and cultivation of a wild mushroom species isolated in Brazil' http://www.uel.br/revistas/uel/index.php/seminabio/article/view/3697/2973 some kind of accidental fruiting using a casing layer with activated charcoal
'COMPARATIVE STUDY ON NUTRIENT AND MINERAL PROFILES OF MUSHROOM SPECIES Macrolepiota procerus CULTIVATED ON TWO Mansonia altissima SAWDUST FORMULATIONS' Can't find the link to the full paper right now, but this one does not meet any scientific standards. Regarding fruiting they just say: Quote:
Fructification and harvest The tied fructification bags were opened after 33 days, and the mycelia watered every morning and evening to enhance fructification. Mushroom flushes plugged from these substrates were then obtained for analysis.
There are very few reports of outdoor success. The most interesting one can be found here: http://gra103.aca.ntu.edu.tw/gdoc/93/D91623803b.pdf
Quote:
GARDEN CULTIVATION OF THE PARASOL MUSHROOM Hansson, G. and Hansson, L. Funginova AB, Mannarp Bolet, S-310 40 Harplinge, Sweden Technology for garden cultivation of the parasol mushroom (Macrolepiota procera) was developed. The growing substrate was a mixture of Agaricus compost and sawdust, pasteurized in bags with 4 kg of substrate. The bags were inoculated with grain spawn. After a 6-8 wk spawn run, the blocks were planted, usually in April, in lawns or pastures with a grass turf on top of the block. During 1992–2000, approximately 300 blocks were planted throughout Sweden and monitored for productivity. Almost 95% of the blocks produced mushrooms, providing there were no abnormal soil or weather conditions. There was wide variation in yield, number and size of mushrooms, duration of fruiting, and other parameters. In general, when planted in April, mushroom production began in August to September of the same year, usually after heavy rains, and continued for two years. Average total yields ranged from 0.6-1.2 kg mushrooms per block. Between 5-10% of the blocks failed to produce mushrooms, but 10% showed sustained production for up to at least 8 years, with yields of greater than 5 kg per block. Since 1996, approximately 800 blocks have been produced and marketed to customers in Sweden.

Thanks for the info Carlsten. I don't know why I only saw it now. My patch and the pile I got it from produces a handful every single day. The pile I got it from has been fruiting for over a month now. Which makes me wonder why our cultivated species fruits in flushes and not daily.

Well, I hope yours turn out to be good edibles!
Here in central Europe M. procera had to adapt to dry periods, fruiting after heavy rains. I once read about dutch commercial trials a couple of decades ago, which haven't been too successful. They got indoor fruitbodies, but not many and kind of deformed. Anyway, I still think it should be possible to mimic the climatic parameters which lead to pinning and fruiting. I'm pretty sure, rain is the key, so I got to find a clever way to test it without risking the mycelium to drown and rot.

I looked at the weather comparison between where I am, Philippines and Stockholm of course temperature-wise, there's no comparison but the only thing similar is the level of rainfall during our dry period which is when my "pile" is fruiting. Hot and dry here, lots of sunshine. It drizzles every 5 days or so, only the top inch gets wet. Maybe that's a clue.
