The short answer
When you shop for liquid culture in Australia, "10ml LC Syringe" (the way Summer Breeze Mycology labels its range) and "10cc Isolated Liquid Culture" (the way What The Fungi labels its own) describe the same kind of product: a 10 millilitre syringe of living mycelium in a sterile sugar broth. It is not a spore syringe. "Isolated" means the vendor says the culture comes from one selected individual, and a number after the name is that vendor's label for the isolate.
Both vendors are Australian, so the syringe never crosses the border, which matters far more for a live culture than for spores. Every Psilocybe culture on Culture Cave is listed for microscopy and taxonomy only. The full range is gathered on the liquid cultures Australia page.
Liquid culture vs spore syringe
A spore syringe holds dormant spores suspended in sterile water. Nothing is growing inside it, and held up to the light it looks like clear water with fine dark specks.
A liquid culture, usually shortened to LC, holds living mycelium in a weak, sterile sugar broth. Held up to the light you see white wisps, threads or small clumps, and the broth is often pale straw or light amber from the sugar.
Spores are forgiving about heat and time in the post; an LC is alive and is not. For Psilocybe lines the use is narrower than many buyers expect: under a microscope an LC shows hyphae, septa and clamp connections but no spores, so it tells you nothing about spore shape or size. For spore morphology, a spore syringe or print is the right sample. Spore syringe vs liquid culture sets the two side by side, and the liquid culture guide covers how LC is made and judged.
Isolated vs multispore, and what the numbers mean
A multispore sample holds thousands of spores, each a slightly different genetic individual, so the sample is a mix. An isolate is one individual picked out of a line and kept going on its own, so everything sold under that name should carry the same genetics. That is the claim behind What The Fungi's "Isolated Liquid Culture". Isolated vs multispore syringes goes deeper.
The number after a name is the vendor's own label for an isolate, not a generation count or a grade. Lines such as Iceberg 608 from Summer Breeze and Natal Moon 315 from What The Fungi use the number to point at the single specimen the vendor took the culture from, and Golden Satellite 186 uses it to separate one isolate from others with the same name. Read the listing for what a particular vendor means by it. There is no industry rule. How to read a strain name covers the rest of the shorthand.
10ml and 10cc are the same volume
One cubic centimetre (cc) is one millilitre (ml), so a 10cc syringe and a 10ml syringe hold exactly the same amount. Neither unit tells you anything about the quality of the culture.
The rest of the title is what is worth reading. What The Fungi uses "10cc Isolated Liquid Culture" for its LCs and "10cc Isolated Spore Sample" for some isolated spore syringes, and those are different products in different categories.
The lines Australian vendors list as LC
Summer Breeze and What The Fungi list several dozen named LC lines between them, and most fall loosely into a few families. Descriptions are the vendors' own; many Summer Breeze listings carry none.
Albino and leucistic lines. Summer Breeze lists True Albino Teacher, which it describes as "recognised for its albino appearance with blushing blue gills", and Leucistic Hell Hound. Broadly, true albino lines lack pigment even in their spores, while leucistic lines are pale but keep pigmented spores (see albino, leucistic and true albino explained).
Gates lines. What The Fungi lists Black Betty Gates, which it describes as an Albino Emerald Gates iso by Dichotomous Keys. Summer Breeze lists Rango Gates and a second Gates line, both without notes. See Gates lines explained.
Jack Frost and Toque family. Summer Breeze lists Jack Frost, and What The Fungi lists FROTO, its in-house cross listed as Jack Frost x Toque. The Jack Frost family tree shows how these names connect.
Melmak lines. What The Fungi lists TAM (True Albino Melmak), described as a True Albino Melmak iso, and Swamp Mak, its in-house cross of Leucistic Swamp Ghost and Melmak XXL. The Mak and Melmak family post explains the name.
Natalensis crosses. Summer Breeze lists NAT Moon. What The Fungi credits Natal Moon as a cross of Ochra and Phobos by Fungus Frequency, lists its own 315 cut, and lists in-house crosses with Natal Moon as a parent. Psilocybe natalensis vs cubensis covers how the species differ under the microscope.
What The Fungi also lists isolates of wild Australian landrace collections, covered in Australian landraces.
Gourmet liquid cultures
Gourmet LC is where liquid culture is used for growing food. Oyster, lion's mane, shiitake and king oyster are often started from LC: a grower adds a few millilitres to sterilised grain, lets it colonise, then moves it to a bulk substrate. Aus Myco Kingdom (AMK) lists gourmet liquid cultures and colonised grain bags, both marked coming soon.
The rest of AMK's range covers a gourmet setup: sterilised grain bags, all in one grow bags, a hardwood based wood lovers substrate, and pre-poured agar plates in high and low nutrition versions, the low nutrition plates described by AMK as suited to liquid culture testing. Meanwhile the gourmet cultures category lists edible species from other vendors, and the mycology supplies guide for Australia covers the gear.
Why liquid culture is best bought inside Australia
Australia has strict biosecurity rules on fungal and other biological material arriving from overseas. Parcels can be inspected, held or destroyed at the border, and live cultures in particular may need an import permit; the Department of Agriculture's import conditions database, BICON, sets out the conditions. An LC from an Australian vendor never crosses the border.
Heat is the other reason. Live cultures are heat sensitive in a way spores are not, and a syringe left in a hot letterbox, on a sunny doorstep or in a depot over a weekend can arrive spoiled. Domestic parcels go by Australia Post (Parcel Post or Express Post) or courier, priced in AUD. Summer Breeze ships within Australia only; What The Fungi ships within Australia and worldwide. In the hotter months, read ordering cultures in the Australian summer first.
Checking an LC syringe on arrival
Open the parcel as soon as it arrives and hold the syringe up to a window or lamp, cap on.
- Clear broth. The liquid between the mycelium should be transparent, pale straw or light amber.
- White mycelium. Clean white wisps or small clumps that spread through the broth when gently swirled.
- Warning signs. Milky broth that does not settle, a green, pink, yellow or grey tint, or dark sludge usually mean contamination. Photograph it and contact the vendor promptly.
Then put it straight in the fridge, at roughly 2 to 8 C on a middle shelf rather than the door, inside a sealed bag. Never freeze an LC: ice crystals rupture the living cells. Because an LC is alive it slowly uses its broth even in the fridge, so ask the vendor how long they suggest keeping it. How to store spore syringes covers the same fridge routine for spores.
Before you order
Read the full title and description, note whether it is an isolate and what any number means, and check its category. Each listing on Culture Cave is sold and shipped by the vendor who prepared it, and you pay that vendor directly, so questions about a culture go to them. Psilocybe and Panaeolus spores and cultures on Culture Cave are sold for microscopy and taxonomy use only, and buyers must check the law in their own state or territory, as it differs across Australia and nothing here is legal advice.
For spores rather than live cultures, start with mushroom spores in Australia or buying mushroom spores in Australia, and for each vendor's range see Australian spore vendors compared.
