Psilocybe hollandia

Psilocybe hollandia
As its name suggests, Psilocybe hollandia is a new truffle developed and grown in the Netherlands by the country’s leading truffle producer. Nearly twice as strong as the other varieties, it’s already popular with experienced shroomers looking for a longer trip with more intense visuals (which hollandia delivers more reliably).

Though a tad more expensive, the hollandia does offer more bang for your buck – you can easily squeeze two trips from one 15 gram pack (in fact it’s recommended that all but the most experienced trippers stick to a half pack).

The taste has also been improved with a special growing method. The hollandia still has the nutty truffle flavour but without the sourness of other varieties.


As a rule, all truffles have a high level of psilocybin in them, so the effects of all of them are broadly similar. But P. Hollandia is the exception. With twice the level of psilocybin, its visual effects are more colourful and overwhelming than any other variety, and the trip will be longer than the usual 4-6 hours (but not double).

Effects will be felt within 15-45 minutes of consumption, depending on how many you took and how long since your last meal. A typical trip consists of a ‘coming up’ period, an experience plateau, followed by a gradual descent back to normal consensus reality.

The effects include: outbursts of hilarity, changed colour and sound perception, introspective thoughts, feelings of universal connectedness, waves of energy coursing through the body, vivid visions with eyes closed.


The active ingredient in truffles is psilocybin, a triptamine similar in structure to our bodies’ naturally produced neurotransmitter, DMT. There are no poisonous byproducts or metabolites created – psilocybin is ridiculously non-toxic - so no hangover. But you may look at life a little differently the next day!


Hollandia are sold in a duo-pack of 2 x 7.5 grams so you can easily split the 15 grams of truffle. Although this weight may be reduced as water is lost during shipping & storage, the effects are the same.

Truffles are sold fresh so you need to keep them in the refrigerator until you use them. Take 7.5 grams for a normal trip and 10 - 15 grams for a strong trip. Try to eat them raw on an empty stomach for best results, or crumble then and boil them gently for 20 minutes to make a tea, which can be sweetened (with honey, not sugar).


Avoid using when pregnant or nursing, when depressed, on medication or in combination with stimulants or alcohol. Also avoid driving motorized vehicles. Not suitable for under-18s. If it’s your first time on psilocybin it’s a good idea to have a friend with experience to be with you in case you feel nauseous or anxious. Do not repeat a trip for at least a week – not because it’s dangerous but because it’s a waste of money! The body rapidly builds up a tolerance for psilocybin so taking a fresh dose too soon after the last one will have no effect.

*Can be stored for a maximum of two months in the fridge. After you open the pack they can only be kept for two days.

    Title : Shroomy!
    Comment : First experience with Magic Mushrooms. Took all the bag. It was fucking awesome, but more spiritual than visual (just some deformations, not true hallucinations). Shrooms are made to teach you something. Don't waste this Nature gift for "fun" only. Psylocibin is ostia for all who love truth and want to know their roots. Enjoy !

    Title : Awesome
    Comment : First time user. Took 15 grams at home alone. It was intense but I never felt scared. Lasted 6 hours and it was beautiful. For the best result be brave and do 15 grams. And have a intension with your trip. For me it was love and divine guidence. Dont forget music. It will guide you. I recommend shamanic music.

    Title : S.T.R.O.N.G.
    Comment : The shrooms came in a perfect condition, no mold or anything like that. Tasted fine, a bit nutty. it was my first shroom - experiment - and wow…. of course I didn´t follow the introduction. I was on holiday, it was afternoon, had breakfast and some Champagne… and I tooksome some little pieces, and I saw, yes, I like the feeling, I was just making a fantasy drawing, and the drawing got amazing. But at a certain point, I wanted more effects, and took a few bits more, and after a while… i was completey lifted up. I drank bottles of water, and tea, I was freezing, took a hot bath, and went with thick pullover into bed. My whole central nervous system was shaking me through - and I had visions, never seen before. Not on LSD nor on strong Cannabis either. I was part of a big, bright, colourful, mycelium, vivid colours, and patterns, and sympols. There was a door, I had to pass through… amazing. But as scientist I am always critical. The things you see are not real and you are not on higer level of evolution and psilocybin is no teacher, like a brand name may suggest. It teaches you nothing. Maybe it make you come into contact with your deepest fears or biggest energy. But everything you see is an illusion. Seeing it that way, it is relaxing to be in Wonderland. But what I learned as hard fact: It is a serious intoxication, in the case of shrooms are not so smooth like Cannabis, though not so earthshaking like LSD. Somewhere inbetween. Water always helps. Bad moments pass by. You can be sure. won´t miss the experience. It was great trip, thanks for that!

    Comment : Perfect service with Zamnesia, congrat. About the product... We took 1 box (15gr) between two. It was a nice, soft and visual trip of 5 hours. Really good way to start this 2016! And next time we will try with 2 box :)

    Title : 15grams nice fun trip. not too intense.
    Comment : I took the whole 15grams of Hollandia as I am a very experienced pychonaut, expecting a very strong trip. I definitely didnt trip as hard as expected but that could be due to the fact I had taken magic mushrooms 9 days earlier. I took these truffls at 6am when I woke up and decided to go on a walk through wildlife preservation near my house with a flask of lemon and ginger tea (great way to get rid of an upset stomach). I did not notice many visuals that were close but distances that were far were beautiful, trees dancing like they were made out of some natural undestructive fire). I came back home and noticed my walls and ceiling were breathing abit and a strange descrete fractal pattern had occured. watched Samsara, as you do when on mushrooms and then took some benzos at the point of when visuals had ceased but would enjoy to prolong the body high. all in all I think its great these are legal, not quite liberty caps but what can you do. if they were stronger or cost less than would be 5 star

Wie lange halten sich die Trüffel in der Verpackung sodass sie noch frisch sind? Beispiel: Wenn eine Lieferung 3-5 Tage dauert, wie lange danach kann man sie noch mit gutem Gewissen verzehren?
