We’ve seen springtails and slime  a couple of times previously on this blog; now here’s the next instalment in the springtails series: springtails and rust fungi. I spotted this rust, Melampsora populnea, on Dog’s mercury (Merculiaris perennis) during yesterday’s walk. From the top of the leaf, all you see is a small area of puckering and some pale spots (near the hole on the leaf in the lower part of the first photograph below). But, on the underside of the leaf, it’s a different story, with the orange blobs typical of a rust fungus.

At the time, I didn’t notice the tiny creatures munching on the fungus, neither the minuscule orange ones nor the relatively large pale orange ones. I presume the smaller ones are the offspring of the larger, which are definitely springtails, though I don’t know which species of Collembola these are, and my photos aren’t precise enough to identify them more precisely.

Dog's mercury, Melampsora populnea, primrose, Puccinia primulae, rust fungi, rust on Dog's mercury, rust on Primrose

I was admiring the glorious display of Primrose in a local wood when I noticed that many of the plants’ leaves had yellowish spots on their upper leaves. Rust, I thought, and, sure enough, on turning the leaves over, I could see the tiny cup-shaped aecia on the undersides, which confirmed this as Primrose rust (Puccinia primulae).

I found this second rust during today’s woodland meander. It’s Melampsora populnea on Dog’s mercury (Mercurialis perennis). Once again, there are yellowish marks on the upper leaves and, this time, rather than cups, there are minuscule splodges of yellow underneath. Neither of these rusts seems to do much harm to the plants.

Fungi foray: Merthyr Mawr

Saturday dawned fine and mostly sunny, good news for most but not such good news for fungi enthusiasts, who are already bemoaning the recent lack of rain. Still, keen-eyed fungi fans can always find something and our Glamorgan Fungus Group has some of the keenest in ‘Eagle-eyes’ Emma. Though we were just a small group of six and a half, we enjoyed a splendid day searching the woodland areas of Merthyr Mawr National Nature Reserve, and our limited numbers were, in fact, a bonus, as we had amongst us the county recorder for Orthoptera (grasshoppers and related insects) and an experienced botanist, so we were able to enjoy, discuss and identify a broad range of flora and fauna. As expected, our fungi finds were limited but we finished the day with a very respectable total of 21 species and had a great time along the way.

Here are some of our finds: the rust Melampsora populnea on Dog’s mercury; another rust Kuehneola uredinis, on Bramble; Microbotryum silenes-dioicae, a smut that occurs on the anthers of Red campion flowers; another rust Melampsora epita var. epitea on Spindle; fungi enthusiasts inspecting the one group of cap fungi (‘real mushrooms’) found this day; the ‘real mushrooms’ that must remain unidentified as they were much eaten and turning gloopy; likely one of the Mollisia species of Disco fungi; Phellinus hippophaeicola on Sea buckthorn; Phylloporia ribis on Spindle; a rather old and faded Blushing bracket Daedaleopsis confragosa; a Puccinia species of rust on Common ragwort – this needs microscope work to positively ID; and the pimple-like growths of Dandelion wart Synchytrium taraxaci on one of the gazillions of Dandelion species, so Taraxacum officinale agg.
