Podosphaera filipendulae: conidiophore


Podosphaera filipendulae: conidia with fibrosin bodies

conidia with fibrosoin bodies


mycelium amphigenous, also on stems, white, persistent; infected stems often distorted. Appressoria indistinct. Conidia oval, formed in chains, with fibrosin bodies. Cleistothecia, often in groups, with a single ascus, containing 6-8 spores. Appendages numerous, ± equatorial, 1-5 x the diameter; they are ± stiff, curved, septate, simple, dark brown when mature.


Rosaceae, monophagous

Filipendula kamtschatica, ulmaria, vulgaris.


morphologically, the fungus cannot be distinguished from Podosphaera spiraeae, and on this ground it has long been considered synonymous with that species. However, DNA research has demonstrated that two perfectly separated species are involved.
