They are fungi that appear when "Tsubaki" trees are in bloom. Their spores sprout on the "Tsubaki" flowers that have fallen nearby and grow, digesting the flowers. After that, they survive in winter as sclerotia and produce mushrooms again in the following spring when "Tsubaki" trees begin to bloom. 2026-04-10T17:45:00+09:00
