The “A+” strain cubensis is a strong culture and average colonization times. Prolific fruiter with beautiful pins with caps sometimes covered in inverted warts. This strain tends to have very large fruit that sporulate heavily. Easy to fruit strain and a classic. This is the same strain that the more popular Albino A+ strain mutated from. If you are looking for a reliable strain for your microscopy purposes, this one is a must have in your collection.
