The golden oyster is an attractive fast growing mushroom that fruits on a wide range of woody substrates. The mushrooms grow in clusters of small, thin fleshed, funnel-shaped yellow caps. The flavor improves dramatically with thorough cooking. Mushrooms tend to be bitter and sour when raw or undercooked.

The golden oyster mushroom, like other species of oyster mushroom, is a wood-decay fungus. In the wild, P. citrinopileatus most commonly decays hardwoods such as elm. The first recorded observation of naturalized golden oysters in the United States occurred in 2012 on Mushroom Observer, perhaps a decade after the cultivation of the species began in North America, and they have been found growing on oak, elm, beech, and other hardwoods. Naturalized golden oysters have been found in many states including: Delaware, Illinois, Iowa, Maryland, Massachusetts, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin.

Their vigorous range expansion is comparable to invasive species. In a 2018 population genomics study comparing naturalized wild isolates with commercial strains, two of the commercial isolates showed high similarity to all of the wild isolates, representing possible source strains of the wild populations. The study also found highly similar wild isolates collected from geographically distant locations, in some cases over 800 miles apart (>1300 km). This is strong evidence to suggest that the same cultivated strain has been re-introduced many times over in various parts of the United States, as opposed to a single introduction event and subsequent spread.

What Is Liquid Culture?

Mushroom Liquid Culture is a nutrient solution with live mycelial bodies suspended in it. It comes in a filled 10cc syringe with a needle, and is entirely sterile!

Is Liquid Culture Different from Spores?

It sure is! Mushroom spores are the microscopic "seeds" of mushrooms.

Liquid culture is when those seeds have "taken root", so to speak! Mushroom spores are very sturdy, and well suited to storage and transport.

Liquid culture offers you a way to add rocket fuel to your gourmet grows, and get to your desired fruiting bodies much faster!

Looking for spore syringes, instead of liquid culture? Head over here!

How Do I Store Liquid Culture?

Keep your liquid culture ideally in the fridge for up to a year. You can also keep it in a cool dark place for 3~6 months.

How Do I Use Liquid Culture?

Get yourself some substrate, an agar plate, or whatever medium you choose, attach the needle provided in your kit, and inject a small amount into your chosen medium!

When Will My Liquid Culture Ship?

Generally speaking, liquid cultures ships on the next shipping day. Check the calendar here!

Should I Consume Liquid Culture?

No. None of our samples are for consumption under any circumstances.

While our liquid culture is made just from liquid sugars and distilled water, you should never consume it.

What Comes In My Package?

Each kit comes with 10cc of sterile, live mycelium in nutrient solution and a single 18Ga needle for use.

Under no circumstances contact us about cultivation of active spores regardless of legality in your home location. Doing so will result in a cancellation of all open orders and denial of any future orders.

While all of our products are made in the most sterile conditions possible, sometimes contamination happens! I'll make it right!
