"Chesser Group", 31/05/2016

No mushrooms in sight for this meeting but plenty of interesting material all the same.

First up the flowery spores of a smut Urocystis eranthidis on the back of an Eranthis flower


Next is the hyphomycete . These hyaline-ended spores are blastospores, which are produced by budding off the end of the conidiophore (conidio-spore producing structure).If only I could remember which species and from which substrate ...



Another hyphomycete, this time with spores which break off from the tip of the conidiophore. From a blackened carrot - Thielaviopsis basicola


 A pathogen of fern this time, with these spores coming from Milesina murariae  on Asplenium ruta-muraria (Wall Rue)


Next up was a coelomycete on Typha (bulrush) which produces its spores out of acervuli (Latin derivation "little heap"), which are saucer shaped receptacles where the conidiopheres grow. A coelomycete is like a hyphomycete but it has a fruit body of sorts ("ceolum" is from the Greek work "cavity"). The cavity could be an acervulus or it could be a pycnidium.

Technically I suppose these cavities aren't really receptacles - transmitacles?



A large and profusely sporulating Peziza went under the knife next and after some deliberation proved to be Peziza micropus, with a little foot/stipe as the name suggests, though this was only obvious on the smaller of the two fruit bodies. The larger fruit body demonstrated the size that a sporocarp can reach when on wood chips - fungus steroids.


Paraphyses shot with ornamented spore contamination!

Episphaeria fraxinicola, Lochgelly 31st March 2016

This little faker makes you think it's a discomycete and then ... boom! A basidium heaves into view!

It's a lover of ash as the name implies, and that's where this was found too

Another hyphomycete - Ascodichaena rugosa

With all the twig-bothering that's going on related to lichens and pyrenomycetes you can't help running into hyphomycetes. This one took a bit of running down, partly because I was searching under the wrong tree in the literature, but turned out to be Ascodichaena rugosa. Very cute under the microscope, as is often the way with hyphomycetes.


In context - terrible photo though

Birch leaf deconstruction

In nature nothing is wasted and not least vegetable matter. These nice three species are all findable on fallen Birch leaves at the moment


Left is Discosia artocreas, centre is Gnomonia alni-viridis (syn. setacea) and right is Venturia ditricha.

The Discosia is nice under the lens, with spores which have appendages and whose ends are entertainingly cyanophilous


These are all from Calis Muir Wood in Dunfermline
