On Juglans cinerea. Host identity according to the Urban tree database of the city of Helsinki.
Inside a red kiwi, imported from Italy (Cesena) by a local food store. I must have hit the ant with my spoon because its middle body shows fresh signs of damage.
Kuiva pihanreunusniitty. Laidunhistoriaa.
Deformed shoots on Populus tremula. There seems to be eriophyid mites present. Aceria dispar might fit, but there does not seem to be records from Finland.
Korkealla puiston puissa. Vaikutti olevan kunnossa. Christer Casagranden löytämä.
Ascospores filiform, 62-115 μm long
Pujoilla (Artemisia vulgaris)
On open silicate cliff.
Medulla K-, C-, KC-, UV+ white; very difficult to find pure white medulla since almost all was turned dark brown or black, including inside of the podetia (last photo shows an opened podetium),
On underside of the leafs of Campanula rotundifolia
On Glechoma hederacea
Collected from edge of pond at night with plankton net made of stocking fabric. Viewed one hour later via low-power bright-field light microscopy.
It is estimated that 50% of all individuals observed showed blue markings. This photomontage shows range of severity from very mild, on far left, and increasing rightwards.

On the wall of an old barn. Looks like a (parasitic) Calicium on Hypocenomyce scalaris.
Chromocyphella muscicola?
on Schistidium moss, rock wall of graveyard
Same as like https://www.inaturalist.org/observations/73138774
If this family, then it will be first in Finland.
This obs is for the fungus. There is another obs for the Trichia botrytis Myxomycete.
Ruhjelaakson pohjalla suolla. Näytti kiinnostavan ruskeansävyisiä kärpäsiä.
Gall on Chamaenerion angustifolium.
Seilin saarella runsaasti ainakin polkujen varsilla
Useita tämän lajin kärpäsiä kiivenneenä heinäkasveille ja kukille. Kuolleita, siivet auki

Larvae (reddish) feeding on Coleosporium tussilaginis on leaves of Tussilago farfara
In threat of being destroyed due to a parking lot; apparently a spontaneous hybrid between local u. glabra and ornamental u. minor.
Leaves completely bald (also mostly bald from below; could be their age) and smooth unlike U. glabra which feels like sandpaper, branch angles are about 90 degrees while glabra makes more narrow angles. Unsure of leafbud hairiness/baldness due to its wetness at the time of observation, but the colour and shape are like those of u. laevis. Didn't know to check for exact leaf shape, but at least some asymmetry at the base of the leaf is visible on the first photo. The tree is three-trunked and growing on top of old foundation stones, suggesting its origins might be from root stems from a deceased mother clone, if not from a seed. The exact spot of growth has to be quite dry, and U. laevis is a wetland species, which was one of the reasons i was somewhat unsure of the interpretation. The place also indicates it cannot be a planted individual. Considering the spot, the tree is in marvelous condition. The leaves aren't showing any sign of senescence yet, unlike the nearby, clear U. glabra individuals, which are in the middle of dropping their leaves. Originally i took this as a hint towards the locally continental cycle of U. laevis; planted continental species tend to not to go into senescence as early as more coastal species, like the very earliest Fraxinus excelsior as a prime example, but upon closer inspection, hybrid vigor explains it as well.
@kalleruokolainen took a sample of this specimen into the university herbarium for further investigation, and found it to be U. x hollandica.
