High Humidity/Fungal Slime Mold

While less common, extremely high localized humidity around the flower spathe can sometimes trap dust or fungal hyphae that resemble fine webbing. This is usually accompanied by a slimy texture rather than dry silk.

Common

How to confirm: Touch the webbing to see if it feels tacky or wet rather than dry and brittle like silk.

1 Gently wipe the flower spathe and surrounding leaves with a soft, damp cloth to remove the slime and trapped debris.

2 Improve air circulation around the plant by spacing it away from other dense foliage and using a small fan if necessary.

3 Monitor soil moisture levels to ensure the medium is not staying overly saturated, which can contribute to localized humidity.
