IKI stained asci of a yet unidentified pyrenocarp #lichen on bark of salix. It will have to wail a little while. Beautiful nevertheless.

Petractis clausa #lichen on soft limestone (marl). Easily missed when not looking careful. The spores have a gelantinous perispore that can be visualized by negative contrast with india ink - you have to carefully prepare a sample without any substrate or other particles though.

Paranectria oropensis on Lepraria sp. Look at these little orange perithecia!#lichen #lichenicolousfungi.

The fungus is supposed to have (sub)muriform spores with pointy ends. The preparations I have done so far only have immature spores. I probably will try again with a larger (older?) perithecium.

Oh. I just realised that it was transferred to the genus Ciliomyces as C. oropensis... pubmed.ncbi.nlm.nih.gov/40746713/

Lichenicolous fungi are fascinating but sometimes frustrating. This Lepraria incana lichen has two anamorphs on it. However the one with the darker larger conidia is accentuated around a dead mite, so it might be arthropod specific? Any ideas? #lichen #lichenicolousfungi

Paranectria oropensis on Lepraria sp. Look at these little orange perithecia!#lichen #lichenicolousfungi.

In more detail from the stereo microscope. This species was new to me but not that difficult to identify. The lichenicolous ascomycetes are still a mess of literature - I hope a Flora of Lichenicolous Fungi 3 - Ascomycetes will be out sometime #MycoBookClub.

Warum hieß es bei allen Demos von Bauern, Querdenkern, Impfgegnern immer "die Sorgen der Bürger ernst nehmen" - aber bei den geplanten GenZ Demos für mehr Bildung, Gerechtigkeit, Klimaschutz heißt es "Pack" und "Mob" und die Union fordert Versammlungsverbot bzw Bundeswehreinsatz?

Epithamnolia xanthoriae (Brackel) Diederich & Suija on damaged X. parietina. #Lichen #Lichenicolousfungi

I don't do #moss regularly. Is this okay for Polytrichum piliferum?

A lichenicolous fungus on Chaenotheca cf. trichialis #lichen. I think this might be something...sometheing Acremonium s. lat. however I cannot find any species parasitizing on Chaenotheca. I guess I am a lichen-pathologist today. Something to sleep over. #lichenicolousfungi

Can this be a (very odd) growth form of Chaenotheca ferruginea? It was growing in a spot with abundant Ch. ferruginea (also on the same tree). #Lichen. The ap. are nearly sessile, nearly urceolate. Spores would match Ch. ferruginea and thallus has red spots, K+ crimson. Photobiont is Trbx.

What is your favourite trick in preparing #Lichen? My current is: When you dip an acupuncture needle in moist PEG it gets sticky and you can pick up very small things. Put 'em in a drop of water on the slide and the PEG dissolves and detaches from the needle.

Moss spore capsules usually have 1 or 2 rings of peristome teeth around their open mouth. In Tortula muralis, the teeth are long & spirally twisted to form a slender tube that twists & untwists in response to humidity changes. This peristome is 1.4 mm long. Stereo pair; viewing instructions in ALT.

I haven't been #lichen posting regularly but hope to resume. Here is some Rinodina pityrea from trunk base of an old poplar.

Does anyone happen to recognise this white fungus on the underside of Bramble (Rubus fruiticosus agg.) leaves? I've not been able to find any particularly helpful structures, but wondered if it was a mycoparasite on one of the Rubus rusts?

The exchange with @isabelrfernandes.bsky.social made me at least test the stereo microscopes capabilities. I so whished I could show the mind blowing 3-dimensionality of the #Aquatichyphomycetes spores in water (everything in the sample is fixed, nothing to culture unfortunately).

Bright field also looks good. Now mostly everything has settled to the tripod state and the mesmerizing twirling has stopped.

And oblique. If these still show up on a thin film I might be able to pick these with fine pins (acupuncture needles) -- this would be the next experiment. @fayrnhawk.bsky.social @jandbio.bsky.social

I think the Olympus BX50 from the 2000's is one of the most beautiful microscope frames*. It like the clear, geometric lines. More architecture than product design. Any other vintage BX here? #microscopy #PathSky

*I adore the black Leitz Ortholux I but would never use it for day to day work... and I don't have one :-(

The autumnal Ilmenau in #Lüneburg yielded a foam sample rich in #AquaticHyphomycetes - in all forms and sizes. Notably absent are Clavatospora longibrachiata and Articulospora tetracladia.

I cannot really place this one. Is it some Campylospora sp. or Gyoerffyella sp. What do you think @jandbio.bsky.social @fayrnhawk.bsky.social?

If you see me awkwardly handling a 3m collapsible carbon fibre pole with a kitchen strainer taped to it its to get some foam from the river.

📢CALL FOR COLLABORATION📢 My PhD student Warre is looking for flies infected with #Laboulbeniales fungi. Especially Musca domestica! If you have any, store in 96% ethanol or in the freezer, record on @inaturalist.bsky.social, and/or contact Warre. #TeamLaboul #LFEE #LuminaQuaeruntur

Sometimes you cannot get nice #lichen samples with lots of substrate. Pressing a post-it note (and rubbing) to a beam of an timber framed house can maybe give you some chance to sample coniocarps!

17 Sept

The coniocarp has very small spores and I end up at Chaenothecopsis pusilla - again... Having a sample does not make it easier.

14 Sept

I had a chance to sample some foam for #AquaticHyphomcetes yesterday. Most very exciting but still fun to look at after some hiatus. From the Hasenburger Mühlenbach in #Lüneburg.

I wasn't the only one taking samples on this trip!

A glory shot of Tubeufia cerea on oak lignum. #Fungifriends #Microscopy #Ascomycetes

To round things up: If small ascomycetes on ascomycetes are not your thing you can look next to them on the stick. I believe this is the anamorph of Tubeufia cerea (Helicosporium vegetum). #Fungifriends #Microscopy #Ascomycetes #Hyphomycetes.

Even obscurer interests? While looking at the pyrenomycetes on wood I came across an even tinier Fungus, mostly on old pyrenos (later also on lignum): With friendly help on iNaturalist I now think this is Tubeufia cerea. #Fungifriends #Microscopy #Ascomycetes
