Rating

I cannot seem to post in the website queries forum so this seemed the next best place. I have noticed some, but not all, threads in the identification forum have a rating. Can anybody enlighten me as to where this comes from and what it means please.

Re: Arum maculatum: a full set

Thank you Fay and Peter. I am using Ellis and Ellis and they list it as Ramularia ari . I know it is lax of me not to follow up every taxonomic review so thank you for pointing this out. I assume it is a nomenclatural change based on a tighter delimitation of the genus Ramularia ? If so, I shall ann...

Re: Arum maculatum: a full set

Thanks Mark, I had forgotten all about this. It is very interesting that the sunken spots seem to be genetic.

Re: Larva on boletus

Perhaps a little to add to Mike's excellent summary. Whilst known host data is provided in the Handbook, host specificity has been poorly studied, mostly through difficulties in rearing the species through (too wet, too dry, etc) but also I suspect because entomologists don't routinely identify fung...

Re: Thoughts on ID's please

That looks like hardened sap, exuded by the tree at the site of a wound, to me. It looks like a branch has broken off underneath it.

Re: Scarlet Elf Cup - Orange Variant Sarcoscypha austriaca var. lutea

Just a few thoughts on the matter. Yellow, orange and red colours in Pezizales are caused by the presence of carotenoid pigments. These can be broken down into the xanthophylls (those which contain heteroatoms, usually oxygen in the form of a hydroxyl group) and the carotenes (those which contain no...

Re: Parmelioid lichen for ID

Thank you Mark for such a speedy and comprehensive reply. The explanation of soredia and isidia is very useful. I shall re-examine the specimen in light of your suggestions. The impression I got of the specimen was only one lichen but...

Parmelioid lichen for ID

I came across this parmelioid (is that a valid word?) lichen on what I think is Quercus branches. I really struggle with the lichen keys as I find they place a lot of emphasis on spores. I have also never quite worked out what the difference between isidiate and sorediate is so perhaps I am on to a ...

Re: Fungus dryers

Thanks Mike. Those links look really interesting. Will have to read the second one in more detail at some point.

Fungus dryers

I think for next season, I should be a little more thorough in drying some of my finds to give me time to work on them before the inevitable moulds set in. My current Heath Robinson approach (an old plant propagator containing an egg tray) tends to give uneven results, I think because there is littl...

Spilopodia nervisequa

Alas, no phtograph, but a few years ago I was shown this fungus on a foray. I have been searching for it since and had come to the conclusion that perhaps it wasn't found in Derbyshire. People must have thought I was mad, any Ribwort Plantain causing an immediate prostration with a hand lens. Finall...

Re: Please can you help with this Boletus ID?

A photograph of the leaves of adjacent trees would help if you cannot identify the trees yourself. I am seeing what look to be a willow species but it could just be one off.
