Problems growing Pleurotus Pulmonarius
    #4354553 - 06/30/05 09:30 AM (11 years, 5 months ago)

hi mates, i'm being crazy growing Pleurotus pulmonarius. i inocule spores solution into jars with bran + perlite at 27-28?C and it grows very fast but when the jars are fully colonized i want to make the casing adding other bran + perlite or other ingredients (sorghum, wheat, sawdust..etc) but it ALWAYS become all punk. this also if the mycelium is outside the chamber. I've also used ultrasonic humidyfier (also to permit gas exchange) but ..nothing!

Can anyone help me? thank you all mates.

a casing layer should be non-nutritous.
pleurotus does not require a casing layer.
and that is a very strange recipe.

good luck

A very strange recipe indeed..

You might have more luck with a more common used tek for oyster cultivation:

Inoculate an agar plate with some spores, when the plate is fully colonized inoculate a jar of sterilized grain with an agar wedge and use the colonized grain to inoculate pasteurized wheat straw as a bulk substrate. Here is a good link: http://www.kitchenculturekit.com/Mushroom/

If you don't have agar you can inoculate spores directly to sterilized grain. A pressure cooker is a must though, especially during summer when the spore load in the air is high.

Pleurotus Pulmonarius fruits at higher temperatures than Pl. ostreatus but they will still be difficult to fruit in the souring summer heat in Italy. I am keeping my cultures in the fridge at the moment, waiting for cooler times.
