Location: Austria, Vienna Ottakringer Wald Date: Feb 8

I found something beneath a tree with epiphyta , which I thought to be Viscum album but is vividly yellow instead of white and I found no leaves.

My search of subspecies of Viscum album initially revealed:

Viscum album subsp. austriacum (Wiesb.) Vollmann. Fruit yellow; leaves 2–4 centimetres (0.79–1.57 in). Central Europe. On Larix, Pinus, Picea.

But then I began to think it shouldn’t be V. album. In illustrations of V. album there aren't the thin stalks between berries and branches as in my specimen.

Perhaps Loranthus europaeus?

You are quite right: it's Loranthus europaeus. Vienna was the prime example in our botany lectures where to see that plant without a fuzz.

c/p from the Flora of Vienna: "Auf Eichen, vorzüglich auf Quercus pedunculata und Qu. sessiliflora, selten. Im Eichenwalde von Schönbrunn, auf dem Gallizin, hinter Neuwaldeck, hin und wieder; viel häufiger auf dem Bisamberge {A}. ... auf den grössern Donau-Inseln z. B. ... in der Lobau {C}."

"Häufigkeit des Vorkommens: häufig bis sehr häufig"

(Confused about the contradicting "rare" and "frequent to very frequent" statements, but anyway.)

Here are some more pictures.

    $\begingroup$ The first „selten“ only applies to the case of quercus. He/she lists „locations“ in order of ascending probability. $\endgroup$

  • $\begingroup$ I suspect your are right, but I can't be sure. Would have assumed to be the probability/frequency to be in brackets after Q. sessiliflora if it would relate to frequency on the host. $\endgroup$
