Possible Flammulina velutipes

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Possible Flammulina velutipes

Post by Bob Hazell » Sun Jan 13, 2019 2:05 pm

The attached photographs were taken at Draycote Water near Rugby, Warwickshire on Friday. The fungus was growing on a dead tree in a small deciduous copse in a damp area of the reservoir. I assume the fungus is Flammulina velutipes. The cap is smooth, orange-brown and marginally darker towards the centre. The cap margin is faintly striate. The stipe is cylindrical velvety and dark brown and slightly yellower at the top. It appeared to be causing white rot of the sapwood. However, under the bark on the sapwood around the fungus was also what appeared to be a very clustered "spot" fungus significantly smaller in size than Dacrymyces stillatus. Confirmation of Flammulina velutipes and any thoughts on the "spot" fungus would be much appreciated.

Hello Bob,

Yes Flammulina velutipes for your first.
(Unless the powers that be have changed the name or decided to split things up because of genome sequencing etc. :roll: :D )

As for your second, I'd be looking at something like Nectria or Neonectria, but wouldn't like to hazard a guess as to particular species.

Regards,
Mike.

There are several Flammulina only separable by microscopy. See Funga Nordica 2012. Or Field Mycology Vol 12 (3) Fungal Portraits.

The most likely confusion is with Flammulina elastica which grows on willows (Salix) and has larger spores.

But not exclusively. From the article "It appears to have a particular preference for willow (Salix spp) although other hosts are known as in the collection below."

Thank you everyone for your comments. As always I am very grateful for your expert contributions and guidance. I appreciate microscopy is often required to provide definitive identification although I am loathe to spoil specimens for this purpose - rather with my limited knowledge leaving specimens pristine for others to enjoy. Thanks again.

Agreed, which is why I said 'most likely'. ;)
