All spawn listed in this collection is discounted because it is overstocked or slightly older, but still healthy and viable for home indoor production. Only species that are overstocked will show an inventory. 

They are all 6lb bags.

'Harbor Blue' Pleurotus ostreatus NSPO1: This is a very productive commercial strain from Pennsylvania. It produces dense clusters with dark gray/blue caps. It produces best in cooler temperatures but also performs well during the warmer months. Averages 1-2 lbs first flush off of 5 lb supplemented sawdust blocks but will also produce off sterilized straw substrate.

'Popham Oyster' Pleurotus ostreatus NSPO2: Produces highly branched clusters of off-white/tan mushrooms that yield better in warm temperatures.

'Snow Oyster' Pleurotus ostreatus NSPO3: Produces very dense clusters that are pure white in color. This strain performs very well during the coldest months of the year but is not recommended for warm weather production.

'Shmoyster' Pleurotus ostreatus NSPO15: An alternative blue oyster strain. Darker in color than our PO1 with impressive yields. A serious oyster with a serious name.

Pleurotus ostreatus NSPO16: A big, beautiful strain of blue oyster producing characteristic blue-gray caps and especially large fruiting bodies. Also more tolerant of higher CO2 levels.

'Black King' Pleurotus spp. NSPspp.1: A cross between strains of Oyster and King Trumpet, the Black King produces brown, marbled caps and soft stems but fruits in warmer temperatures than King Trumpets. A favorite of chefs and mushroom cultivators alike.

'Saffron' Pleurotus citrinopileatus NSPC1: This commercial strain produces relatively dense clusters of bright Golden Oysters. Fruits best at warmer temperatures. Showy mushrooms are great for farmers' markets and local accounts but are generally too brittle for long distance transport.

'Northern Sun' Pleurotus citrinopileatus NSPC2: A commercial golden oyster strain. Known for having denser fruit bodies that are less brittle than other citrinopileatus strains.

'Rose' Pleurotus djamor NSPD1: This Oyster species produces large flowery clusters of bright Pink Oyster mushrooms. This strain is very fast growing and tolerant of non-sterile cultivation techniques. Fruits best at warmer temperatures and is not recommended for cold season production.

'True Italian Oyster' Pleurotus pulmonarius NSPP1: Dense Oyster species that produces wavy, brown-capped mushrooms with a relatively low moisture content. They are a great farmers' market Oyster and add nice variety to mixed mushroom boxes.

'Stephen King Trumpet' Pleurotus eryngii NSPE1: Commercial mushroom strain originating from Japan that produces mushrooms with large stems and small tan caps. This strain is more tolerant of warm temperatures but still fruits best in cooler weather.

'DK' Pleurotus eryngii NSPE2: A commercial strain that produces large fruiting bodies. Similar to our Stephen King Trumpet, it fruits best in cooler weather. 

'Willow Pioppino' Agrocybe aegerita NSAA1: A commercial Pioppino culture that produces flushes of velvety-capped mushrooms with snappy stalks. These mushrooms are relatively sturdy and are not too brittle for distance shipping or delivery.

'Jelly Roll' Pholiota nameko NSPN1: A good indoor producer that will make copious amounts of the nameko mushroom's quintessential gelatinous coating when grown with proper humidity. Needs cooler temperatures to fruit!

'Lion's Brain' Hericium erinaceus  NSHE1: Commercial strain. Very productive forming dense pom pom fruit-bodies. Fruits best in cooler temperatures. 1/2-1 lb yield on first flush off of 5 lb supplemented sawdust with consistent subsequent fruitings over several months.

'Tree Beard' Hericium erinaceus NSHE3: A showy strain of Lion's Mane that produces commercially viable flushes of less uniformed fruiting bodies, adding variation to your Lion's Mane boxes.

'CombTWOth' Hericium corraloides NSHC2: A commercially productive strain of Comb Tooth. Unlike the dense 'pom poms' of hericium erinaceus, hericium corraloides produces large, coral-like fruiting bodies with branching spines.

'207' Lentinula edodes NSLE1: A new name for a favorite commercial strain for indoor block production of shiitake. Yield averages .75-1.5 lb first flush off of 5 lb supplemented sawdust blocks. Fruits best at colder temperatures and tends to produce mushrooms with smaller stems and large caps. Our culture is direct from Belgium and retains the highly desired characteristics of this strain.

'Acorn' Lentinula edodes NSLE2: A variation on commercial indoor shiitake genetics. We've had similar results from this strain as from our '207' strain listed above. We like having multiple varieties of the same species to ensure genetic diversity and reduce the odds of crop failure.

'Rudolf' Ganoderma lucidum NSGL1: Our favorite indoor reishi strain. Produces dense and colorful antlers when grown indoors in bags. Best grown using filter patch bags with minimal air exchange.

'Speckled Chestnut' Pholiota adiposa NSPA1: Commercial strain from the west coast. This species produces dense clusters of scurfy, tan-colored mushrooms. A visually striking mushroom that is highly prized by chefs. First flushes average 1-2 lbs off of 5 lb supplemented sawdust blocks.

'Basic Beech' Hypsizygus tessellatus NSHT1: Our favorite brown beech mushroom strain. Great for commercial production.

'Advanced Beech' Hypsizygus tessellatus NSHT2: A pure white beech strain, but similar to our HT1.

'Birdie' Grifola frondosa NSGF1: Commercial strain from the west coast. This species produces a tasty polypore that has a similar flavor to eggplant.
