on Boraginaceae ?


spermogonia and aecia are not known. If host plant alternation does occur at all, it will probably involve Boraginaceae.

uredinia brown, up to half a mm long stripes dispersed on (mainly) the upperside of the leaves, occasionally covering the entire surface. Urediniospores spinulose, with 10-12 dispersed germination pores. Telia on the underside of the leaves and on the leaf sheaths, less than a mm large, covered by the epidermis, divided into small compartments by rows of brown paraphyses. Teliospores 2-celled, short-conical, narrowed towards the pedicel; wall smooth, thickened near the tip; pedicel short, persistent.

uredinia, telia

Poaceae, narrowly oligophagous

Anisantha sterilis, tectorum; Bromopsis erecta; Bromus arvensis, hordeaceus, japonicus, lanceolatus, secalinis.


many authors, including Termorshuizen & Swertz, and also the Index Fungorum (2016), consider this species conspecific with P. recondita.
