Red Raspberry Slime Mold
Tubifera ferruginosaAlso known as Raspberry Slime Mold, Red Raspberry Slime
Red raspberry slime mold begins life as a mobile, single-celled plasmodium creeping silently over decaying wood to engulf bacteria and fungal spores. When ready to reproduce, it congregates into eye-catching clusters of tightly packed, cylindrical sporangia that resemble miniature raspberries. Over several days, the brilliant coral-pink or crimson globes mature, turning dull purplish-brown before releasing powdery brown spores on the wind.

- Why interaction risk is low
- Safe to observe at a normal distance.
Responsible observation
- Look on damp wood: Search shady, rotting logs and decaying stumps after humid summer rains.
- Observe color shifts: Revisit colonies over 48 hours to watch them transform from vivid pink to dull brown.
- Use a hand lens: Magnification reveals the fine, tightly bundled hexagonal tubes that form the cluster.
