Laccaria tortilis?

[NickWood]

Thank you very much for your previous help. Another query : )

A tiny, stocky fungus.

Round, light-brown, funnel-shaped cap, with light and dark striations and a central dark depression. Up to approx. 2cm in width, becoming very irregular.

Height up to approx. 2cm. Gills widely spaced, gills and stem similar in colour to cap. Spores white (sorry to photo).

Habitant: Found in moss on concrete bank of canal. Extensive along canal bank, but individuals growing separate (not usually in close clusters). 19 November 2017, Warwickshire

Initial ID: Twisted Deceiver – Laccaria tortilis

Hi,

Could well be wrong, (as it generally has a slightly darker apical region to the stipe), but I think your fungus has the general hallmarks of Lichenomphalia umbellifera.

Regards,

Mike.

Not Laccaria tortilis which has well-formed gills rather than these somewhat reduced, interveined ones; habitat is wrong as well. Microscopy needed but I would suggest something along the lines of Arrhenia rickenii. Interestingly I have collected A. rickenii in moss on a formerly concreted area:

On the subject of these umbilicate fungi has anyone else noticed that the Wikipedia page for Omphalina https://en.wikipedia.org/wiki/Omphalina” class=”bbcode_url”>https://en.wikipedia.org/wiki/Omphalina has a photograph which almost certainly shows Rickenella fibula?!

edit pace Mike but I think those gills are not quite right for Lichenomphalia either; plus I can’t see any evidence that this agaric is lichenised . . .

Many thanks, Mike and Chris, for your quick, thoughtful, and informative responses – greatly appreciated.

Arrhenia rickenii looks very promising (wonderful info image, Chris), but clearly I must get a microscope soon!

I found Laccaria tortilis in its usual place under eucalyptus today. In-situ pictures were naff but it had two spored basidia
