DESCRIPTION
Psilocybe cubensis R-44 Spores
Straight from Ralphster's Spores! An excellent addition to any collection.
Psilocybe cubensis “R-44” is an enigmatic strain with origins shrouded in mystery and mycological lore. Believed to have first surfaced in the early 1990s from Ralph at Ralpshster's Spores. R-44 gained attention in underground circles for its distinctive growth characteristics and reliable spore production. The “R” stands for “race,” though its precise lineage remains a subject of speculation among enthusiasts.
Scientific Characteristics:
-
Spore Color: Deep, dark purple-brown—classic for P. cubensis spores.
-
Shape & Size: Spores are broadly elliptical, averaging 12–17 x 8–12 micrometers when viewed microscopically.
-
Appearance: R-44 spores display consistent shape, heavy pigmentation, and a smooth surface texture, making them easy to identify in spore collections.
-
Mycelium Traits: Noted for producing thick, ropey mycelium, often described as “vigorous and determined” by seasoned researchers.
-
Fruit Body Notes: When cultivated (in legal jurisdictions), R-44 tends to form medium to large fruit bodies with golden caps and sturdy, straight stem.
Research Use:
R-44 is a favorite for mycological microscopy due to its reliability, dense spore prints, and fascinating genetic background. This strain’s consistent morphology makes it a staple for both amateur and experienced researchers interested in P. cubensis diversity.
