Yellow Umbo Liquid Culture Syringe

Yellow Umbo is a cubensis strain that takes its name from the way its caps often form a distinct, raised bump—or “umbo”—right at the center. That feature, paired with its warm golden coloration, makes the mushrooms easy to recognize among other nats. The caps can spread broad and flat with age, but they almost always keep that little sunlit peak in the middle, as if marked with a brushstroke of color. The stems are sturdy and pale, giving the fruits a balanced, classic silhouette. Under the microscope, its spores show the same vitality, with a density that feels as steady as its growth habit. Yellow Umbo has a simple charm: not overly rare, not overly wild, just a strain that wears its defining feature proudly in its name and appearance.
