      Here’s a photo of Trochila ilicina, taken with the eye cam on ToupView, using an IKEA desk lamp as the illumination:

      It’s a terrible photo, but that’s probably because it’s my first!!

        Hi

        That doesn’t look quite right for Trochila ilicina; more likely a ‘coelomycete’ perhaps a Coleophoma. Checking the ‘innards’ would help . . . .

        regards

        Chris

          That’s strange…

            Check this page by Chris Johnson (a respected mycologist) – you can see distinct “eye-shaped” apothecia. To be honest, it looks different to both your fungus and the plate by Chris :?

              OK . . . .

              now I have seen all three photo’s I agree, this looks like the very early stage of Trochila ilicina quite a while before the “lids” open; seeing a single apothecium misled me.

              I must have a word with Chris J. ;); Adam is quite correct, his fungus does indeed look different – it is Phacidium multivalve, another very common species on Ilex, probably the anamorph:

              [attachment=0]Phacidium multivalve.jpg[/attachment](note the rod-shaped conidia)

              Cheers

              PS This is not, of course, in any way intended to impugn Chris Johnson’s excellent website, which has many splendid images of Hebridean fungi, including many species without similar images on the Web. The portraits of mosses are of extremely high quality as well.

                Hi Guys

                Just been tipped-off by Chris Y about your new forum – news filters through very slowly to the Outer Hebrides. I hope it’s a great success and wish all those involved the best of luck.

                Thanks for the nice comments regarding my website – pity it’s centred around getting one wrong 😳

                Out of action for 3 months while work is carried out on extending my study area but hope to be active again by mid-August.

                Regards, Chris

                  Welcome to the forum Chris, sorry word didn’t get to you about the forum. I guess you weren’t on Lancashire Lad’s list! ;)

                  I had no idea your ID was wrong, you never know with these plant diseases if it is a certain stage, or morph!

                    Hi Chris,

                    Good to see that you’ve found the forum!

                    As Adam has suggested, When WAB went kaput, I didn’t have any contact details for you, (along with quite a few others), so was unable to get the word out to everyone.

                    Regards,

                    Mike.

                      Hi Mike

                      Much as I thought. Didn’t think I’d been black-listed (yet).

                      Regards, Chris

                          Rather than people having to move to an external website here is the ‘portrait’ (fungi.org.uk gives a bigger image in any case – toggle F11 and it gets even bigger 😳 ):

                          Trochila ilicina.jpg

                          [attachment=0]Trochila ilicina.jpg[/attachment]note the pale olive-green contents of the paraphyses and marginal cells which give the exposed apothecia their characteristic colour. Also note how mounting in IKI (Lugol’s Iodine), while useful for showing positive or negative ascus tip reaction, destroys those paraphysis contents and also loses the distinctive guttules of the spores. This is why it is important, whenever one can, to first examine living material in water – Zotto Baral’s “Vital Taxonomy“: http://www.gbif-mycology.de/HostedSites/Baral/” class=”bbcode_url”>http://www.gbif-mycology.de/HostedSites/Baral/.
