Topic: Bluebell Rust Query
I am hoping that either yourself or perhaps one of the more mycologically minded readers on the Forum can help me here as I have a query about Bluebell Rust (Uromyces muscari). I have always recorded the rust on Bluebell (Hyacinthoides) leaves as U.muscari but have recently had my records entered (with photos) on iNaturalist changed to Uromyces hyacinthi.
On questioning the observation validator he indicated the following: "I am using Klenke&Scholler 2015 to identify rusts. They list Uromyces hyacinthi as the rust on Hyacinthoides. They mention U.muscari f. sp. hyacinthi as a synonym. I don't know what people use for rust ID in the UK, but I could imagine that whatever is used still has U.muscari f. sp. hyacinthi as the rust on bluebells which is why nobody reports U.hyacinthi.".
I have checked Bladmineeers and they show U.muscari but do not show it using Hyacinthoides as a host: https://bladmineerders.nl/parasites/fun … s-muscari/
Whereas Bladmineers does show U.hyacinthi as using Hyacinthoides as a host: https://bladmineerders.nl/parasites/fun … hyacinthi/
I have checked "Roesten van Nederland (Dutcvh Rust Fungi" Termorshuizen 2011 and also "British Rust Fungi" Wilson & Henderson 1966 and neither mention U.hyacinthi at all; so I am assuming that this must be a relatively recent taxonomic change.
Are we behind the rest of Europe on a taxonomic change here ?? Should all the records of U.muscari on the NBN Atlas be changed to U.hyacinthi ??
I would be grateful for any clarification you (or anyone else) can provide.
