Notes: Telia hypophyllous on leaves, containing angular uredospores and rough teliospores.

It's very difficult to interpret the spores: there are a mixture of types:





Pale, thick-walled echinulate cells (peridium?)
More or less smooth, brown, rounded-polygonal pedicellate cells (uredospores?)
Roundish, warty, brown cells with hyaline pedicel with a short apical cell (teliospores)
