Comparing UK spore vendors: seven questions worth asking before you order

There are more UK spore suppliers than there were five years ago, and the listings look alike. The differences are underneath: how the syringe was filled, whether the name means anything, and what happens when something goes wrong. These are the questions that separate them.

011. How is the syringe prepared?

The only acceptable answer is under sterile protocol, in a flow hood, from a logged print, into sterile water. A supplier that cannot describe its process is describing a kitchen. MycoWorld prepares every syringe this way in the UK and explains it in how spore syringes are made.

022. Is there a LOT number?

A batch reference on the syringe ties it to a print, a date and a set of records. Without one there is no traceability, and no way to replace a bad batch. Every MycoWorld syringe carries a LOT.

A supplier that cannot describe its process is describing a kitchen.

033. Isolate or multispore, and does the listing say?

Many vendors sell multispore syringes under names that imply isolation. Look for an explicit ISO tag and a described phenotype. MycoWorld marks isolates on the card and credits the geneticist who worked them.

044. Where did the genetics come from?

A named breeder, a documented cross and a lineage you can follow. If the card cannot tell you what a line is a cross of, or who made it, the name is decoration. MycoWorld catalogues by collection (What The Fungi, Sporexchange, A.C.S, Mushrealm) and draws every cross on the lineage explorer.

055. How fresh is the stock?

Syringes that have sat for a year in a warm stockroom are still sold as new. Ask when the batch was filled. MycoWorld prepares to order in small batches and refrigerates from hood to post, so the LOT date is recent.

066. Dispatch, packaging and tracking?

UK dispatch in one to two working days, tracked, in unbranded packaging. Overseas vendors mean customs delays and warm transit. See what to expect from delivery.

077. What happens when something goes wrong?

A compromised syringe should be replaced without argument on a photo and a LOT number. That is MycoWorld's policy, and a supplier that will not commit to one is telling you something.

08The honest comparison

On price, some vendors are cheaper. On the seven questions above, the answer is usually the difference between a research specimen and a syringe of unknown water. Read the listing, ask the questions, and choose the supplier whose answers you can check. The library is built to make every one of those answers visible on the card.

Specimens for this story: DreadMaw (Gamma Decay iso), ACS Ochra, BLUE VOOTWO (ACS Blue voodoo iso) and ACS ABV440, all prepared under sterile protocol and LOT-logged in the UK.

Questions people ask

What makes a spore vendor reliable?

Sterile preparation, LOT logging, honest isolate labelling, documented lineage, fresh stock, fast tracked dispatch and a replacement policy. Any supplier should be able to answer all seven.

Is a cheaper spore syringe a worse one?

Not always, but a very low price usually means old stock, no hood, or a multispore line sold as an isolate. Ask the questions above.

Does MycoWorld sell to the whole UK?

Yes, to adults for microscopy, taxonomy and research, with tracked dispatch from the UK.
