Chrysomyxa woroninii Tranzschel, 1903
on Picea
gall
The fungus is systemic in young shouts. Both the shoot itself and the needles are strongly shortened and swollen to such an extent that the whole gives the impression of an elongated cone. They have got a sweet taste, and even are considered edible in northern Scandinavia. Soon the needles are covered by golden yellow aecia; the copious amount of spores gives the branches a golden hue.
