Marasmiaceae is a large family of mushrooms that are all drought-tolerant, having the ability to shrivel up in dry weather and then re-grow. The best-known member of this family is the shiitake mushroom, an edible mushroom that is used extensively in Chinese cuisine for its strong flavor. Note, however, that most members of this large and diverse fungus family are not edible.
Marasmiaceae includes 1,600 species of fungi, featuring both edible types like Shiitake and dangerous ones like Jack-o-lantern (Omphalotus Illudens), which causes vomiting, stomach cramps, and diarrhea when ingested. The bioluminescent nature of Jack-o-lantern poses a risk, especially for children who might find its glow enticing but is generally not mistaken for edible types by experts.
