Close up of aecidia of Puccinia sessilis Puccinia sessilis is a fungal plant pathogen, also known as arum rust or ramsons rust.Bio-images Puccinia sessilis It commonly infects Arum maculatum and Allium ursinum causing yellow to orange circular patches on leaves. On the underside it produces raised orange aecia commonly covered in spores. It is common in Eurasia in the spring. Other species affected by this rust include Convallaria majalis, Dactylorhiza fuchsii, Dactylorhiza incarnata, Dactylorhiza majalis, Gymnadenia conopsea, Neottia ovata, Paris quadrifolia and Phalaris arundinacea Ecological Fora of the British Isles - Puccinia sessilis A specialised form, Puccinia sessilis f.sp. narcissi-orchidacearum Boerema & Kesteren (Aecidium narcissi) is a cause of rust in daffodils (Narcissus) and various wild Orchidaceae.

09Environmental DNA2 detections
Where the DNA of Puccinia sessilis was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
