Notes:

Yellowish or pale green to faintly brown tinged, wart-like swellings, 1.5-3mm diam, on one side of the leaf lamina; the other side forms a shallow dimple. The swollen side has a coarse surface as though the cells are bursting apart like a sponge.

Spores: abundant, hyaline, 15-21x12-13µm, rounded to slightly angular often beaked, with irregular hyaline wall upto 7µm thick which is cracked and thus appearing very rough, contents 12-15/9-11µm globose to ellipsoid. The wall is unstained in lactophenol cotton blue while the contents stain blue.
