The tubes were then removed from the rotator and placed on a magnetic tube rack for 3 minutes. Following this incubation, the tubes were returned to the magnetic rack, the supernatant of both tubes were removed using a wide bore tip and pooled in a fresh Eppendorf tube.
Quast Gurevich et al. Reads were assembled into 32 contigs with lengths ranging from 32 kilobases to 4. The Peregrine assembler requires at least 2 HiFi reads to substantially overlap to contribute to a contig and as a result we did not observe any bacterial contamination in the assembly BUSCO v3. FunAnnotate v1. The final genome assembly was aligned to three other public Psilocybe cubensis datasets Fricke et al. In total, Mapping rates were determined using samtools flagstat on bam files Li et al.
Alignments were visualized with MUMmer V4. A different Psilocybe species Psilocybe cyanescens genome was also mapped with much lower mapping efficiency. Three Illumina genome assemblies Reynolds et al. Left is Psilocybe cyanescens from Reynolds et al. Middle is McKernan et al. MGC Illumina assembly. Right is Fricke et al. Illumina whole-genome shotgun data McKernan et al. The annotation from the funannotate pipeline was converted from gff3 format into SnpEff version 4.
Of these, , Lastly, as a quality check, the original Pacific Biosciences CCS corrected shotgun reads were mapped back to the reference with minimap2 version 2. A total of 15, variants are identified and 15, Whole genome shotgun reads mapped back to their consensus reference should produce predominantly heterozygous calls in a diploid organism. Scripts utilized to for variant calling are in github and described in the Data availability section.
The N-methyltransferase gene responsible for Psilocybin production in P. Illumina read mapping of the McKernan et al. The 4. Other SNPs also exist in these genes and should be considered in context of this deletion.
Further work is required to understand the biological significance of this variation. Top track is Medicinal Genomics Illumina whole genome shotgun data of a different P. Third track is Psilocybe cyanescens genome mapped to HiFi P. A highly contiguous Psilocybe cubensis genome has been generated. The N50 contigs lengths are 75 fold more contiguous than the existing assembly available at JGI.
This reference can aid in the identification of genetic variation that may impact psilocybin, psilocin, norpsilocin, baeocystin, norbaeocystin and aeruginascin production. The authors have provided changes for all the comments and requested edits and I deem all of them to be acceptable, and to have much improved the manuscript. There remains one typo that the authors may wish to correct: In the last section of the Polymorphisms section, "utilized for" should replace "utilized to for".
Are sufficient details of methods and materials provided to allow replication by others? I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard.
McKernan and colleagues present on the first highly contiguous draft genome for the magic mushroom Psilocybe cubensis. We commend their use of High accuracy long read sequencing and an advanced bioinformatics pipeline to build a much more complete picture of the P.
The methods employed are state of the art and the authors provide sufficient access to the data to enable peers and the public to replicate the experiment. The peat moss is water to the point were only a few drops of water is running between my finger and then sterilize.
Originated from a wild Florida P. Isolation was carried out and ended with a cloned fruit. The strain is very aggressive and colonises most substrates in exceptional time. Defining characteristics of this strain include: mycelial spots on cap, symmetrical caps, mycelial growth well along the stem, and an umbilicate cap.
Joshua who isolated this strain hopes that all will enjoy it and that it will be spread to mycologists throughout the world. This classic strain has been in circulation for quite a few years now and we've always been pleased with it's performance on cased grain and riceflour cakes. Even under less than optimal conditions this strain is able to produce an adundance of medium to large sized mushrooms. Although it is not as fast fruiting as the more slender stemmed Equador and Cambodia strain the size of the fruitbodies more than makes up for this.
Fruitbodies in later flushes can get massive in size. The name 'Golden Teacher' refers to the golden color of the caps and stems and the way it teaches people about spore microscopy. This is a wonderful and unique strain that produces very large fruitbodies that are considered to be very potent for a P. It's ability to produce larger than normal fruitbodies is balanced by it's limited number that it yields. However, the overall yield ends up equal since one of these GTs can grow larger than 3 or 4 other P.
GT's tend to be a little picky when finding a good mate after inoculation which could result in some uncolonized jars of substrate, but once it finds a good match then it will be a very good one that you can count on producing impressive text- book quality fruitbodies that are larger than usual in size. It's worth mentioning that these GTs are some of the best mushrooms to be experienced by those interested in their innate qualities.
This is a potent Florida strain from the eastern coastal region that grows very rapidly in the humid area of the state. Gulf Coast cubensis generally means it is a wild growing cubensis that grows along ocean bordering states near the Gulf of Mexico, such as Texas, Alabama, Florida, Georgia etc. Gulf Coast strains thrive near the humid ocean air climates. Spores from one state can easily travel to the next through birds, farm animals, hurricanes etc They adapt along the coastal states to the new growing conditions and take up habitat near the warm humid ocean inlands.
The Gulf Coast strain is a rather easy one to work with and produces good yields with fruitbodies ranging from average to large in size. It's one of the very few P. This strain has a very interesting history. This strain is collected in a little village in Mexico: Huautla de Jimenez.
Huautla de Jimenez was the hometown of Maria Sabina. She was a mushroom shaman. Bob Dylan, John Lennon and a lot of other famous people traveled to this place to witness and experience a ritual with her. She died in and is since then a legend in- and outside Mexico. Also the sight of the mushroom is very beautiful. The mushroom has a very unique shaped cap. The mushroom can become pretty tall with very thin whitish stems.
Standard spawn medium: Rye grain Fruiting substrate: Rye grain, pasteurized wheat straw, leached horse or cow manure. This mushroom arrived us by The Little Guy. We won a print in a nice contest on the Shroomery. The original Creeper comes from Keeper. Also an resource for prints, however the most expensive one on this globe. Personally I do not believe in his fantasie stock with fantasie hybrides and exclusive prices.
This strain comes from the Malabar Coast in India. Initial observations of this strain in the wild note it will fruit well in higher than normal temps. This strain is a very poor spore depositor. A characteristic of this species is the attached partial veil. The veil appears cortinate in nature, forming a small web-like pattern that stays tenaciously attached between cap and stem until the mushroom reaches full maturity.
Even fully mature specimens may still have this veil attached. Another fantastic cubensis from Mexico is this strain picked around Mazatapec Mexico. For those of you into the spiritual side of mushrooms, I'm sure you will enjoy this one a lot, as the rabbi has always noticed mushrooms from Mexico tend to deliver a very powerfull spiritual journey.
We've heard a lot of great feedback from Amsterdam people over time on this one haveing very beautiful visions after embracing its gift. Although you may have a tremendous spiritual or visual experience on these, you'll need a little patience.
The little extra wait is well worth it. Her most common name is the 'mexican mushroom'. This big mushroom has a yellow head and a stalk of 8 to 19 centimetres. The Psilocybe Cubensis is very easy to grow, and is one of the most famous magic mushrooms used all over the world.
This mushroom was originally found in Southern Mexico, from Mr. A very beautiful mushroom always giving beautiful spotted caps, usually of a nice yellowish color instead of your typical cubensis golden tan color. If you find that cannabis helps with nausea or anxiety, using it before consuming mushrooms may help ready your body for the trip. When used 3 to 4 hours in when the effects of mushrooms begin to fade , cannabis can slightly prolong the experience and help you contextualize the experience as a whole, according to anecdotal reports.
Consider enlisting a trusted friend to remain sober and sit with you in case things take a turn. For some, cannabis and mushrooms can make symptoms worse. Often, a bad reaction simply involves anxiety and paranoia, which hallucinations may make worse. A trip-sitter can provide gentle reassurance that the reaction is due to the substances you took and that it will pass.
They can also change the setting by guiding the person having a response into a quiet space with soothing colors, music, and aromas. Removing mirrors from the space sometimes reduces the likelihood of having alarming hallucinations.
Just be sure to tell them about specific symptoms so they can send the appropriate response. Have them bend their top knee inward if they can for added support.
This position will keep their airways open in case they begin to vomit. Used separately and together, mushrooms and cannabis can spark creativity and new perspectives. But this combo can also be uncomfortably intense for some and worsen mental health symptoms for others.
As the call for decriminalization and legalization spreads from cannabis to psychedelics, the opportunities to practice responsible adult use are increasing. Educate yourself about the benefits and risks of using these substances, keeping in mind that people can have very different experiences with them. Physical addiction to cannabis and mushrooms is extremely rare, but psychological addiction is more common. If you ever feel like your substance use has crossed the line to addiction, a comprehensive list of resources is available online here.

Psilocybe cubensis, like all mushrooms of the Psilocybe genus, have a hygrophanous nature, meaning their coloration shifts depending on hydration levels, however it is important to note that this trait is less pronounced in the P. They turn a bluish color when handled or bruised, due to the oxidization of psilocin. The underside of the pileus is densely gilled, and they possess a thin gelatinous veil pellicle separating the pileus and stipe.
Pileus caps generally measure from mm in diameter. Early in the fruiting cycle they are often concical opening to broadly convex, frequently with a central umbo bump that remains as the cap opens out, becoming almost plane in maturity. Pileus coloration ranges from reddish cinnamon brown in young fruiting bodies and fades to a golden caramel or pale yellow when mature.
Caps are sometimes darker at the centre, and speckled or mottled white throughout. Lamella gills on the underside of the cap are moderately crowded, narrow at margins and slightly enlarged in the centre. Starting out pale greyish, they gradually darken and by full maturity become a purplish brown, often retaining paler at the edges. Lamella show through as lines or striations on the outer part of the cap when fresh and under favourable lighting conditions. Often the stipe is slightly curved, however relatively stiff and non-pliable.
Whitish in colour, sometimes discoloured near the base and discolours slightly yellowish when dry. Also will quickly bruise blue when handled fresh.
The stipe surface is smooth and often striated near the apex, above the annular zone. The base is frequently covered with white fluffy mycelial tufts.
Spores Dark purplish to brown when deposited and darkening with age, subellipsoid shape. Microscopic size ranging from Psilocybe Cubensis has a farinaceous similar to freshly ground flour odor and taste.
