Re: Coniothyrium on Yucca?

Thanks Paul, they are indeed 4-5 micrometers. I can see how leaf spots such as these are confusing taxonomically!

Re: Coniothyrium on Yucca?

The only clear structures I could see were masses of these small circular particles - spores?

Coniothyrium on Yucca?

Today at Painshill Park in Surrey I came across just a single fungal spot on a leaf of a succulent which I think might be Yucca . Online research resulted in the possibility of Coniothyrium concentricum - does this look plausible? I managed to remove the fungus with a scalpel (trying to damage the p...

Re: Bluish discomycete

Hi Chris Thanks for the link to that key - really helpful! I ran it through the key using the following characters I was able to see on my specimen: Oil 3 KOH+ yellow (not overly strong) Aseptate spores Spores smaller than 13-18(20) x 3.5-4.2 µm These led me to Mollisia fusca , which also seems to f...

Bluish discomycete

Hello Today at Devils Dyke on the South Downs I came across this dark bluish disco underneath a log in Ash woodland (so the log presumably belongs to Ash). It is 1mm in diameter. I've attached photos of the whole fruitbodies along with my best efforts at microscopy. The asci are approximately 5um in...

Re: Discomycete

Thanks Andreas - I think I might leave this at genus level for now - I'll keep your response in mind however for when I'm identifying Lachnums in the future, when I'm somewhat adept. I'll keep the specimen though.

Thanks again

Re: Discomycete

Hi Andreas, Thanks for your response! The tree is an Alder, perhaps that could narrow it down. As for the microscopy, here's a very poor photo of the spores (I think I need to get my 'scope fixed and it's a school night so I couldn't get the proper camera out to measure them). Maybe the shape at lea...

Myxo on mossy trunk

Hello Yesterday while out and about I found a patch of mossy tree trunk covered in what I think are slime mould fruiting bodies. They are mostly yellowish, covered in white granules and with a black 'stipe' with white 'veins' running longitudinally. The older fruit bodies retain the white granular s...

Discomycete

Hello Yesterday I found this tiny discomycete under a piece of bark growing on a living tree. The largest fruit body (shown in the picture) is only 0.5mm along the long axis. I haven't done any microscopy yet in case it's not fully mature and I ought to let it mature first. I considered Snowy Disco ...

Possibly Irpex?

Hello Today I found this crust fungus with clear 'teeth' growing on the trunk of a young Hazel tree. It's not included in Phillips so I did a quick online search where it appears to match Irpex lacteus, however this does not appear to be common in the UK judging by the number of records on the NBN G...
