Evolutionary Pathway Visualization

Variability Through Human Interaction

"Lotus" Type: Bred for broad, thin, flower-like petals that absorb maximum water ideal for smooth cosmetics and soups.
"Dense" Type: Bred for highly compact, tight ruffles that retain a crisp, snappy texture during cooking.

Fruiting Body Architecture (the transition from tight, brain-like crinkles to broad, petal-like sheets).

Wild Variability: Shape varies drastically in wild specimens (size, thickness, fold density) based on humidity and how much energy it can steal from its host.

Human Selection: Centuries of cultivation led growers to selectively breed two major distinct cultivars based on texture and appearance:

The Result: By switching from wild logs to standardized sawdust substrates, human interaction transformed a small, unpredictable wild parasite into massive, uniform, and structurally tailored "blooms."
