Podosphaera amelanchieris
species of fungus
Podosphaera amelanchieris is a species of powdery mildew in the family Erysiphaceae. It is found across Europe and North America, where it affects the genus Amelanchier.
Description
The fungus forms a thin, light, weak coating on host leaves, rarely distorting growth from the underside. Podosphaera amelanchieris, like most Erysiphaceae, is highly host-specific and infects only the genus Amelanchier. Another species of powdery mildew also infects this genus: Phyllactinia amelanchieris, which has weak, very thin, often smooth growth, on the undersides of leaves.
Taxonomy
The fungus was formally described in 1927 by Maurizio. The specific epithet derives from the host genus.
The public source identifies “Podosphaera amelanchieris” as species of fungus. This brief keeps that definition visible, then builds a research path around Podosphaera, amelanchieris and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Podosphaera amelanchieris”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Nov 28, 2025. The linked authority identifier is Q96626907. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1927.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
