The spores from these cubensis mushrooms come from the magical country of Brazil. I've traveled to many places in Brazil and I can tell you it's an amazing country and it was subtropical almost everywhere we went. Lots of rain, lots of cattle or horses nearby and lots of mushrooms. Did I mention lots of beautiful people too? ;)

Everywhere we traveled I had my girlfriend of the time speak Portuguese and I was surprised to learn most Brazilians had some knowledge of mushrooms or knew someone who did. Probably because Brazil is the biggest beef exporter in South America and the spores to dung loving mushrooms are spread around easily on the hooves of cattle and horses. It was cubes we found or were guided to everywhere except on the most beautiful island I've ever been to, Fernando de Nerona, where we found Panaeolus Cyanescens shrooms. We only found a few and we ate them before I could find more and collect spores. Sometimes the excitement of mushroom hunting is a little overwhelming and I forget I’m also there on business to collect spores! The fungi kingdom and God’s beautiful earth that hosts it is a playground :)

Both of the Brazilian cubensis mushroom spores we carry are top shelf, but the Corumba is our growers in Austria's top pick! In fact our grower thinks the Corumba cubensis is in the top 3 best cubensis. This is a fast and aggressive strain that produces heavily and has thick stems usually. Personally I like the patterns of lines in the caps too. It's also a heavy spore producer which is why we usually keep this one on sale. The Corumba Brazil cubensis mushrooms are very generous with dropping spores so we usually have plenty in stock. The Corumba Brazil shrooms don't require much effort to speak to you......enjoy!

Spore Taxonomy
Cubensis Spore Taxonomy	Microscopic Features: Spores dark purplish brown to violet brown in deposit, subellipsoid, 11.5-17 by 8-11 u. Basidia 2- or 3-spores, but usually 4-spored. Pleurocystidia nearly pear shaped, sometimes mucronate, 18-30 by 6-13 u. Cheilocystidia fusoid-ventricose with an obtuse or subcapitate apex, sometimes sublageni form, 17-32 by 6-10 , with the narrow necks 3-5 u broad. One rare cubensis strains named Columbia “rust spore” actually drops almost reddish rust colored spores but this strain is very unique! We do carry spores of that strain from time to time.

I mistakenly ordered a cold weather variety. I received an email recommending these spores instead and I am extremely grateful. Corumba Brazil seems to be almost bulletproof. I have found these spores to be resistant to both temperature fluctuations and contamination. In side-by-side comparisons, these have consistently outperformed the other spores I’ve studied. Perfect for hobbyists of all experience levels!

I only got these on a whim because of a special deal and I’m SO GLAD I DID. Out of all the strains I picked up that day, this one is totally impressing me the most. WOW. Gro()ing super fast and making those amazing patterns in the mycelium. I’m a total noob here but these spores make me feel like I know what I’m doing - they seem to be gro()ing like magic and I’m soooooo excited!!! Thanks for being LEGIT!!! I’ll keep coming back for more!!!

These are my favorite so far. A cube is supposed to be "as they say", a cube but in my opinion there is something very special about this one.

I have ordered this strain time and time again. It's so fast my microscope can't keep up. Lol. Not as easy to see, wink wink, as the penis envy, but very good.

I was sent Corumba spore prints as an extra for a bulk purchase. This is the only time that I have been less than impressed with this compny. The flush was great - many full caps and multiple flushes. However, the potency of this strain was VERY poor. I took 2 grams, waited an hour, and nothing. Took 2 more grams, waited an hour and d felt only a slight heaviness in my body. Took 3 more grams and had some interesting closed-eye visuals and a sleepless night, but nothing else. I would suggest that the Corumba Brazil not be offered in the future. I still very much like this company and will definitely purchase from them going forward! Reply from The Hawk: It's not the Corumba Brazil strain itself, read what others have wrote. It's vary rare I hear of people experiencing this. I do know MAIO inhibitors can cause this, perhaps other meds too. I'm sure as more scientist study these mushrooms they will learn of other things in our diets perhaps that cause temporary immunity to the effects of psilocybin. Psilocybe fungi like substrates high in tryptamine, that increases psilocybin production. Rice is very low in tryptamine thus lower potency mushrooms will be the outcome. Yet rice is the most commonly used substrate. Ps. azurescens, the most potent mushroom tested, grow on stalks of sea grass on the Oregon & Washington coast. Sea grass, and all grass for that matter is high in tryptamine. Azurescens harvested from sea grass always seem more potent than the ones harvested from wood chips. Food for thought
