Finally got my flouresence microscope fully set up. Here are some cross sections of Octospora dyed with calcofluor white.

Some frosted field fungi.

Early germline sequestration in a basidiomycete fungus - PubMed In sexual organisms, inheritance of new mutations is highly dependent on the timing of germline definition. Here, we used the fairy ring-forming fungus <i>Marasmius oreades</i> to challenge the general assumption of a late germline separation in the Fungi. We collected mushrooms from different parts …

Here is the paper! pubmed.ncbi.nlm.nih.gov/40811541/

True. I think I read a paper about it not being possible to determine species of ampelomyces with ITS and they are often even more cryptic. Some day I hope that someone spends a phd to determine the phylogenetics!

Yes! It is very interesting. Unfortunately I think its not possible to tell what species from microscopy. Hopefully someone will come up with a key or somthing about host specificity.

It appears on last years dead petioles. I dont believe that it can infect anything fresh or even dying

The multicolored apothica of Allophylaria campanuliformis. I thought they were quite striking. These fungi grow specifically on fern petioles in this case a male fern.

Senecio squalidus its not that common on this species but ia recorded. I more often find it on Senecio vulgaris

1/🚨 New preprint alert! Can mutualists and pathogens co-colonise the same living plant cell and what does that do to the plant membranes that surround these microbes?

On a roll with these hyperparasites, in this case Sphaerellopsis filum parasitising the uridinia of Puccinia lapsanae that is parasitising Lapsana communis! Now I just need to find a hyper-hyperparasite, how many layers can it go?.

Beautiful!

Pycnidia and conidia

Ampelomyces is an awesome genus of hyperparasite that take over the conidiophores of powdery mildews and produce their pycnidia on them instead! I was lucky enough to find an example on Glovinomyves montagni and was very excited!

Pustula senecionis is a common species of Oomycete that forms large white pustules on the abaxial surface of the leaf!

Happy to announce my first published paper. We discuss the potential use of the endophyte Epichlöe in UK agriculture. I am grateful for the collaboration with my coauthors, Dr. Light, and Dr. Bienkowski, and particularly Dr. Rangel for this opportunity.

Brightfield microscopy

Using polarized microscopy

Odd dark septate endophyte (?) in moss leaves. Interestingly, this moss also contained an Octospora sp.. It is always interesting to think about the possible tripartite interactions occurring within these co-infected tissues.

Did a classic amateur microscope mod and made my scope do polarizing light microscopy! Have tried many crystals but MSG remains the most diverse in colour.

Rihnberg blue and red filter

Some fungal hyphae using different illumination techniques. I have been tinkering with filters and thought it had interesting results and is easily made for any standard microscope condenser! The images are of hyphae growth from a sealed slide.

Melanogaster sp.

Turmalinea persicina

Japanese truffles! I was suprised to find two species of truffles on my last hike, one revealed by a mudslide and the other just sitting under a tree root. The fungal diversity here is amazing!

Daedaleopsis tricolor

Daedaleopsis tricolor has re-evolved gills

Trametes coccinea

Trametes coccinea pores

Some Japanese bracket fungi I found today. Some truly beautiful colours and interesting pores! Very dry at the moment, so there were only brackets persisting apart from a few microfungi and crusts.

Google is so useless now. If you search for a fungal genus it gives you a crappy AI image that looks nothing like it at the top of the results. The other two much smaller images look about right for Resupinatus #fungi #mycology #FungiFriends

Gonatobotrys simplex

Found on old mugwort stems forming beautiful conidiophores with multiple conidial balls between the septa.

Hyphomycetes are often a hidden beauty in nature that are often overlooked!

Day two of infiltration

Fascinating reaserch on how some Metarhizium spp. both act as insect pathogens and form ectomycorrhiza and how this effects nutrient foraging behavior

Described a possible new dimention of fungal germline cell production speculating that some fungi have hyphae set to become germline cells at the begining of their lifecycle.

The genetic changes and evolution of Podaxis species associated with termites.

Incredible time at #MycologyNordics after hearing about it yesterday and infiltrating the conference. Extremely interesting talks and posters. Really inspiring for an undergraduate looking to go into mycology. Hopefully next time I'll be there officially!
