hyaline, smooth but often bearing coronate projections or bumps at the top (in apical spores) or upper rim (in intercalary spores), about 0.5 µm thick at the sides, thickened to 2-4 µm at the apex[2]
caulicolous and forming elongated slits 1-10 mm long or hypophyllous on purplish spots or on minute yellowish spots sometimes surrounded by a purplish halo[2]
closely echinulate, the spines 1.5-2.5 µm apart, 0.5-1 µm high, about 1.5 µm thick but often appearing thinner (c. 0.5-0.75 µm) because the outer layer is conspicuous whilst the inner layer is almost invisible[2]
