teliospores

gal: Uredinia beiderzijdig, geelbruin, zonder paraphysen (zelden met dunwandige paraphysen); sporen fijnstekelig, met 4-9 verspreide poren die vaak een verdikte rand hebben. Telia onderzijdig, lang bedekt door de epidermis, glanzend bruin; ze worden door bruine paraphysen omgeven en gecompartimenteerd. Teliosporen worden aanvankelijk gevormd in de uredinia, later in de nieuw gevormde telia; ze zijn eencellig, peervormig, met een gladde, aan de top iets verdikte wand; steel teninste zo lang als de spore.

gall: Uredinia amphigenous, yellowish brown, without paraphyses (rarely thin-walled ones); spores finely spinulose, with 4-9 dispersed pores, that often have a thickened rim. Telia hypophyllous, long covered by the epidermis, shining brown; they are surrounded and divided in compartments by brown paraphyses. Teliospores initially formed in the uredinia, later in the newly formed telia; they are one-celled, pyriform, with a smooth, apically somehat thickened wall; pedicel at least as long as the spore.

uredinia, telia: Poaceae, oligofaag

uredinia, telia: Poaceae, oligphagous
