Badhamia sp. (2 FC, 1 loc, 1 ps, Fig. 6A&B )

Loc. 2 Mahé: On fallen leaf of palm Nephrosperma vanhoutteanum, AM 3047, TK2795, MM47933 (2FC).

This stalked species has umbilicate and yellow sporocarps. The slender stalk is not furrowed and is 0.93 mm long, black at the base then orange-yellow to orange-red at the top. The peridium is yellow with white lime. Opened specimens show orange-red at the base and bright yellow nodes stretched from the stalk to the peridium. Under the microscope, the spores are 8– 9 μm, smooth, clear. The capillitium consists of yellow granular nodes 225 μm long x 9 μm thick, stretched from stalk to peridium. Hypothallus black. Altogether, these features distinguish this specimen from all known species of Badhamia or Physarum .
