Cycle of development includes pycnia, primary uredinia (functioning as aecia), secondary 
uredinia, and telia, only occasionally showing distinct alternating phases; autoecious. Pycnia 
and other sori subepidermal. 
Pycnia embedded in the tissues of the host, usually globoid or flask-shaped, with ostiolar 
filaments. 
Uredinia erumpent, definite, without peridium, and without paraphyses except in a 
few species, generally of two sorts, primary and secondary; the primary uredinia usually 
accompanied by pycnia, generally in groups, sometimes on much hypertrophied areas, or 
forming distinct galls, the secondary uredinia unaccompanied by pycnia, usually without 
definite arrangement. Urediniospores borne singly on pedicels, globoid, ellipsoid, or obovoid; 
wall in most species colored, sometimes laminate, and in a few species much thicker above, 
echinulate (verrucose in Bullaria Cordiae), the pores one to several, variously arranged. 
Telia erumpent, soon naked, or occasionally long covered by the epidermis. Teliospores 
free, pedicelled, two-celled, occasionally with a few one-celled (mesospores); wall generally 
colored, in a few species colorless, firm, smooth or verrucose, the pore of the upper cell apical 
or nearly so, of the lower cell variable.
