Tubifera ferruginosa is a species of slime mold characterized by its reddish-brown to orange-brown sporangia, typically 1-3 mm in diameter, with a powdery to granular surface and a short, stout stalk. In East and Central Texas, it is commonly found on decaying wood, particularly on logs and stumps in moist, shaded areas of forests, often associated with rich soil and abundant organic matter. The species tends to fruit in late summer to early fall, with sporangia typically appearing in clusters or scattered individuals.
