Marasmius

TheMiesMeister: Thanks so much for your tips and for helping me ID my fungi spottings! ..do not worry too much if some suggestions could be later wrong..I think is also nice to ponder the possibilities. It only makes people curious about the different species and by reading about it while they are being suggested you can only learn more and more..which is not bad at all, right? It is nice to hear you also have some biology background and your line of studies. thanks for telling me :-) I hope I will find some luminescent sp here in Belgium with the tips you gave me!

Thank you so much for your kind words, Marta! I can be very wrong, though! Since I only know European fungi, and a couple of American and Asian species/genera, it is quite possible I am totally off, haha.
At the moment I am studying Applied Biology at the HAS Hogeschool in Den Bosch, and I did some biochemistry and cell biology aswel, but I reckon it not to be as specific as you did. Since I've been studying at the HAS, plants (and trees and shrubs) became of more interest to me, because it tells a lot about the soil and thus about what kind of fungi you'd expect. I want to dig into the world of ecology after my study and with my knowledge of mushrooms, I can try to save special patches nature or apply the right management of natural resources to improve the biodiversity. But that's still a long way from now, haha!
In Belgium there are some bioluminescent mushrooms. The most common one is the Honey mushroom (Armillaria mellea). It has rhizomorphs, the black lace like structures they form under the bark of a tree, which glow in the dark. It is commonly known as 'foxfire'. Another species is Panellus stipticus (Scherpe schelpzwam), which itself is bioluminescent. Here's a page about bioluminescent fungi: http://inamidst.com/lights/foxfire. Marasmius, as far as I know, does not have this feature.
Lastly, I will try to ID as much as I can!

Meismeister: do you know BTW if these glow in the dark? (just curious). Other species that I may find in Belgium that glow in the dark; could you tell me? I would love to search for them and do the trial :-)

Hi MiesMeister. precisely this is why we need experts -like you- to help us discern the species so your comment is very welcome! :-)

Personally I am no expert whatsoever in zoology, botanics or the world of fungi and related. I did study biology but I am specialized in biochemistry and molecular cell biology, which means I know well about cell parts and metabolic processes as well as many names of genes. This is my field. So for the naturalist amateur part on myself I try my best here to reach an approximate guess into the species proposed for my spottings. This guess is many times not the right one and for this reason I welcome very much people who tries to help me narrow down the right species name. Time ago, Lars proposed the species above as guess and as I did see, with my limited experience, a similarity then I added his suggestion as species name. Now you say is wrong. Since I don´t have further arguments to discuss it, I will follow your guidance and expertise and change the name in my spotting. Thanks again and please do not hesitate to help me with more fungi IDs that I may have incorrect. Go to my Profile and search for fungi: some of these are a "black box" for me..I am only at the top of the iceberg for learning species and this is why I love Project Noah so much: because it helps me, by contacting people like you, to learn much more about the wolrd I live in :-)

This ID is incorrect, Lars and Marta, I'm afraid. The dark stem and dry, almost leathery cap tells it is a Marasmius species. Here is a spotting I did about two years ago of Marasmius rotula: http://www.projectnoah.org/spottings/128.... I don't know any Marasmius species from Mexico, so what species it exactly is I cannot tell. The differences between Marasmius and Mycena adscendens, are that the latter one will disappear when it dries up, because it is mostly watercontaining, while the Marasmius will wither, but remain very though and leathery. Also M. adscendens has a tiny disc shaped foot and a very slim, white slightly hairy stipe, where Marasmius has a tough and often dark stem.

Is a pity I did not know at that moment or I would have tried to pick some to illuminate with UV since some are found in Mexico which are luminescent.

yes, indeed, thanks Lars, I will add it ;-)

looks like mycena family
