Orders usually process in 3-14 days, you will receive an order confirmation email with estimated processing time, and another email at the time of shipment with tracking information. Be sure to check your spam folder if you do not see the confirmation email. If you would like to order from outside the US and Canada at your own liability, please email TerrestrialFungi@gmail.com, or contact me on Instagram.
Single ascospore progeny strains bred and selected from isolated ascospores from carefully selected wild specimens from the appalachian mountains/foothills. I am constantly refining my selection process and developing improved genetics, as well as testing new domesticated isolates harvested from my best crosses. I send the top 5 strains for a 5 pack, 3 pack or single pack of liquid culture.
Master syringe should be stored in the refrigerator upon receiving to maximize shelf life and fruiting capability (3-12 months under refrigeration). All LC is batch tested before shipping out. Shake well before using to ensure even distribution of mycelium in liquid. Master can be expanded to bulk LC utilizing 1-2 ml of liquid or whole syringe for optimum results. Expanded LC should be used in 2-7 days for best results, immediate refrigeration after 2-5 days of dark incubation can extend this window.
if you are ordering in the summer to the southern US, consider overnight shipping with a cold pack to ensure viability. I can no longer be liable for handling temperatures during shipping during the summer.
LC expansion incubation: 62-72 degrees F (I prefer closer to 62)
Substrate Incubation: 70-72 degrees F
Fruiting: 62-68 degrees F, they can go as low as 50 with just slightly slower growth.
lighting: dark incubation until fully but lightly colonized for 2-5 days, place under lights for 12-24 hours daily for remainder of growing cycle: 500-1500 lux.
Bare bones LC for Master syringe expansion (mostly any LC recipe is suitable):
6 L water
3/8 cup dextrose
3/8 cup malt extract
1 TBS calcium carbonate
Sediment should be expected, simply agitate regularly when using. An LC recipe with calcium carbonate should not be used with a stir-bar as it will wear out the Teflon coating and grind away at the bottom of the jar. I simply handshake once a day.
1000 ml water
5 heaping cups (1000-1200 g) brown rice
1 TBS (9 g) malt extract
1 TBS (9 g) dextrose
1 TBS (9 g) starch
3 TBS (19 g) nutritional yeast
2 tsp (4.6 g) pea or soy protein powder
1/2 tsp (2.4 g) calcium carbonate
1/4 tsp (1.2 g) calcium sulfate
1/2 tsp (4 g) kelp meal
The calcium sulfate and rock dust can be replaced with more calcium carbonate if you are on a budget. You can also skip kelp.
This is the sub recipe I currently use with the instant pot tek from my YouTube video: https://youtu.be/SmdpM8AoyS8
If you are prepping your substrate in jars use a ratio of 1:1.6 (grains:broth). A good amount for quart jars would be 35g rice to 56ml of broth sterilized for 60 minutes at 15psi.
