Orange bread mold (Neurospora crassa)

Orange bread mold (Neurospora crassa)

Orange bread mold is notorious among commercial mushroom cultivators, mainly because this type of contamination is fairly common and also it spreads extremely fast. If one block of substrate is contaminated, it could take less than 48 hours for it to spread to a entire grow room. Any specimen that display signs of orange bread mold infection should be immediatly isolated / disposed
