      I’m going to try to find Mitrula paludosa on Sunday at Ashdown Forest, I’ve never seen it before and it’s such a beautiful little fungus! :)

          I think not so uncommon as records on NBN Gateway suggest just that people haven’t looked for it. My guess is that it is widespread particularly around the South Wales coast. Also worth looking for Alexanders and the Rust around old monastery sites – Alexanders was widely grown by monks!

              Not sure on correct name but Buczacki et al 2012 list this as Collybia aquosa (Gymnopus aquosa) and uncommon

                Going by Funga Nordica 2012 which considers it common. I think all Collybias are now down to those which grow on other fungi and have a sclerotium.

                I like your signature!

                    Pocket Plum – lots to be found on Prunus at the moment – and a rusty one on Ramsons, helped by Chris Y to Puccinia sessilis.

                          Hi Adam,

                          Not disputing your id but possibly more information on how you got to species on this one for us less experienced fungi enthusiasts?!

                          Incaps Coprinoid Fungi are not easy!

                            I must admit, I find these quite tricky.

                            Dark smooth spores, the dark brown spot in the centre and the radial grooves (pleats) are typical of Parasola. Absence of a veil rules out Coprinellus/Coprinopsis.

                            I’d love to see a photo of the sclerocystidia on P.auricoma as I’m not sure what I’m looking for in that regard (can’t say for sure that is what I see in my photo), but the spore germ pore is central, and the spore size matches P.auricoma (and excludes P.conophila, the only other species with a central germ pore)

                            N.B, the large hyaline “hair-like” object in the micrograph is a nematode! It was wriggling about (photo taken in water) The brown objects are what I assume to be sclerocystidia

                              P auricoma is one of the easiest of these small ink caps to identify. If you are lucky and find one just at the right stage of development and not too wet with a hand lens you will be able to see the setae on the very centre of the cap. If not in perfect condition a small scalp under the scope will instantly show that the hairs are present and you have nailed the id.

                                  I posted an image of the setae (sclerocystidia) on the cap of Parasola auricoma on page 2 of this ‘string’.
