notes
The species of the complex of P. caricina s.l. can be identified only when the host alternation is known. The pictures above therefore cannot be associated with certainty with P. caricina in the strict sense.
gall
aecia also on veins, petioles, green shoots and young fruits; peridium cupulate, white, margin revolute. Locally strong galling and discolouration.
spermogonia, aecia
Grossulariaceae, monophagous
Ribes alpinum, aureun, nigrum, rubrum, sanguineum, uva-crispa.
on Carex

Teliospores 2-celled, almost without constriction clavate, narrowing into the pedicel; wall smooth, apical part of top cell moderately thickened; pedicel hyaline, up to half as long as the spore.

The description above applies to caricina s.str. However, many authors maintain a much wider concept of the species. In that vision P.caricina s.l. alternates between Ribes and a variety of Carex species.
The following taxa described here are members of the complex of P. caricina s.l.: P. caricina, caricina var. ribis-ferrugineae, magnusii, pringsheimiana, ribesii-digitatae, ribesii-diversicoloris, ribesii-pendulae, ribis-nigri-lasiocarpae, ribis-nigri-paniculatae.
inquilines
the uredinia ara parasitised by Eudarluca caricis.
