Florida Oyster Mushroom
Pleurotus ostreatus var. florida

Strain: M 2125

Trumps:

• good cultivation results at temperatures above 20°C
• numerous fruiting bodies - carpophores

Characteristics:

This summer strain forms numerous groups of primordia, distributed over the entire substrate. They develop into medium size (average 5 cm diam.), funnel-shaped fruitbodies with elongated stems. Their colour varies, with increasing light intensity and temperature, from light-beige to greyish blue. The shelf life of the mushrooms is inversely proportional to the cultivation temperature.

Blue Oyster Mushroom, wild strain
Pleurotus ostreatus var. columbinus

Strain: M 2136

Qualities:

• nice and dark fruit bodies of superior quality
• good storage

Characteristics:

This wild variety of Pleurotus ostreatus generates voluminous tufts of bright-blue to brown-grey fruit bodies. These are firmly fleshed (cap diam. 8 à 10 cm.) and therefore perfectly storable.  Due to the less aggressive mycelium there is an increased risk of infections.

Winter Oyster Mushroom
Pleurotus ostreatus

Strain: M 2153

Trumps:

• good cultivation results at temperatures till 20°C
• rapid production of numerous carpophores

Characteristics:

This strain is an interesting alternative to regular Winter Oyster Mushroom strains when a rapid production is requested.  Numerous groups of primordia appear a few days after the incubation period is finished. The diam. of the carpophores, the fruitbody- quality and the intensity of the colour are inversely proportional to the cultivation temperature.

Winter Oyster Mushroom
Pleurotus ostreatus

• quick growing 
• high yield
• stores well

Characteristics:

This strain forms numerous clusters of regularly formed short-stemmed fruitbodies which are grey-blue to grey-brown in colour and average 9 cm in diameter. At temperatures of 18°C and above, the brown tones will dominate and the mushrooms will be smaller in size with longer stems.

This Oyster Mushroom has a good taste and stores extremely well.

Winter Oyster Mushroom

Pleurotus ostreatus

Strain: M 2181

Qualities:

• rapidly growing species 
• very high yield 
• excellent quality of the fruit bodies

Characteristics:

Overall, M 2181 is comparable to M 2191, so it also appears as a typical Pleurotus ostreatus, but is known for fruiting more very heavily in less numerous clusters shaded grey-blue (temperature below 15°C) to grey-brown. These are big, thick (diam. 8 à 12 cm) and short-stemmed.  They are very tasty and they preserve well.

Yellow Oyster Mushroom
Pleurotus cornucopiae var. citrinopileatus

Strain: M 2502

Trumps:

• decorative species
• slight anise taste
• rapid production

Characteristics:

Easy-to-grow oyster mushroom.  Because of their funnel-like shape and yellow colour remind of cantharells.  Tightly clustered fruit bodies (4- 7 cm diam.) are gathered centrally or ex-centrically on a thin stem.  For a maximum storage capacity they need to be harvested before the full development of the cap sides.

Characteristics:

This oyster mushroom thrives in heat.  Over 16°C it forms numerous clusters of pink fruit bodies with variable measurements (from 7 to 12 cm diam.).  At lower temperatures, colour and form deviate.  The mushrooms have no particular taste and are grown primarily for their decorative aspect.
