Parasite on Trochila ilicina?
Vitus Schäfftlein, 28-04-2026 20:33
Hello,

I found Trochila ilicina on Ilex aquifolium (1). Curiously, the part visible on the leaf undersurface happened to have white spots with a central small hole (2). Whilst separating the white part, a macroscopically visible cloud of white conidia escaped from the hole. Under the microscope, I could observe massive amounts of said conidia (3, 4). The conidiophores mostly consisted of just one conidiogenous cell, some were branched once. The conidia themselves measured 12,5 ± 0,4 µm × 2,3 ± 0,3 µm, Q = 5,6 ± 0,7 (5). Does anyone have an idea what species this could be?


Best regards,
Vitus

Re : Parasite on Trochila ilicina?
Isn't this the anamorph? It reminds me of the ?Cryptocline anamorph of Tr. laurocerasi.

Re : Parasite on Trochila ilicina?
You are obviously right, Martin. On Prunus laurocerasus it is Phacidium lauri, and on Ilex either the sam, or Phacidium lacerum.
