if you bored- what's this

[alge]

been watching this for a week, photos taken every 24-36 hours. I have to admit i'm at a loss.

starts around 5mm, but i think the very dry week and hot days have taken their toll, i was hoping one fruit body would mature but the are not doing anything now apart from wilting.






Any thoughts?

Collybia fusipes, and thirsty ones at that!

Thanks nick, faster than a fast thing on a fast day in fastville.

my first venture into unknown Collybia then, i have one reference for the spindle shank and i can only name the very obvious Tricholomatales- wax cap, st georges, fairyring etc. 4 study days coming up and a library overhaul so hopefully i'll be able to spot some once we have had some rain..... not that i'm complaining

erm - except that it isn't a Collybia

Gymnopus fusipes (and with good reason) . . . .

Please expand on the reason why Chris, as the Checklist of the British & Irish Basidiomycota would have us believe that Gymnopus fusipes is a synonym for Collybia fusipes

Yes, do tell, and do stop being mycologically pedantic

[ManwithNoname]

Antonin, Halling and Noordeloos wrote a paper in 1997 discussing generic concepts within Marasmius and Collybia but this is where it all starts getting very geeky.

If you are interested the paper can be found at the following link:

Mycotaxon 63, 1997

Scroll down until you find:

"Antonín, V.; Halling, R.E.; Noordeloos, M.E. Generic concepts within the groups of Marasmius and Collybia sensu lato."

You will have to view one page at a time but Collybia starts on page 360.

Enjoy.

Thanks ManwithNoname it all makes sense now(tongue-in-cheek smiley required):

If Chris had just mentioned that if Alex's field notes had recorded "Pileipellis a cutis or ixocutis of narrow, cylindrical hyphae, without projections or diverticulate endings, lacking encrusting pigments; basidiomata small, often growing from sclerotium in or around mummified remnants of Basidiomycetes" then it's a Collybia, whereas if "Pileipellis a cutis or trichoderm, made of hyphae with none to few or numerous projections, or with lobed to diverticulate terminal elements, frequently with encrusting pigments: basidiomata growing on other substrata, and rarely originating from sclerotium" it's a Gymnopus. "Simples!"

I must admit for me they are now called Collybia er hmmm Gymnopus fusipes , I always think of them first as Collybia and then remember the name has changed . Andreas explained a while back what had happened to the names, and it is somewhat shorter to read than the link that MWNN supplied .... so for those with not too much time on their hands here is the link to his post:

A few more for id

The type of Collybia is Collybia tuberosa which is a member of a group of small agarics chiefly associated with decaying fungi . . . cookei, cirrhata etc.

it became clear to students of the genus (especially - and this is important - as people started to look at fungi worldwide) that the diverse toadstools which had been crammed into this genus were not sufficiently similar to warrant the similarity which a single generic name confers; this was based on habitat preferences, macro and micro-structure and, laterally DNA studies

accordingly there have been three new genera proposed:

Rhodocollybia with R. maculata as type for toadstools with fairly large caps (typically larger than 5 centimetres broad), and a pinkish-tinted spore print. Microscopically, they are characterized by having spores and basidia that are dextrinoid

Gymnopus with G. fusipes as type for fleshy, rather tough fruitbodies and a white spore deposit; the spores are iodine-negative and acyanophilic

and the monotypic Dendrocollybia to accomodate the splendidly anomalous D. racemosa

in addition to the pointers given by MWNN see:
Collybia s.l. in NE United States

and yes "Gymnopus fusipes is a synonym for Collybia fusipes" - the fungus hasn't changed, but the best name to give it is in question - and be honest, would you think that fusipes had much in common with cookei if the Basidiomycota Checklist didn't tell you it was supposed to have? (they're just dragging their feet on this one - if it hasn't changed already in later, digital versions)

I note that while I have been typing all this Melanie has quoted Andreas' on this, but will post anyway

cheers

Chris
