Chrysomyxa ledi (Albertini & Schweinitz) de Bary, 1879
on Picea
gall
Aecia on yellow spots, in one or two rows, on otherwise not galled current-year’s needles. Spores 15-28 x 20-38 µm.
spermogonia, aecia
Pinaceae, monophagous
Picea abies, engelmannii, glacua, mariana, obovata, rubens, sitchensis.
on Rhododendron
gall
uredinia and telia at the underside of the previous year’s leaf. Uredinia orange, telia blood red. Teliospores formed in chains, 1-celled, thin-walled. The fungus is not systemic, only individual leaves are infected.
uredinia, telia
Ericaceae, narrowly oligophagous
Rhododendron groenlandicum, tomentosum.
A reference to Rhododendron ferrugineum and hirsutum by Negrean perhaps rather applies to Chrysomyxa rhododendri.
notes
Similar to Chrysomyxa woroninii, but differs by the absence of the extreme galling of Picea.
