Re: On Succisa

Many leaf spots caused by Ramalina spp do not have a pale neurotic centre. To confirm Ramularia you need to see a white felty layer on the underside of these spots. If not present, they may develop if a leaf is placed on some damp kitchen paper in a plastic box for a day or two. There are no downy m...

Re: Literature & resources for rusts and smuts

Welcome Clare,

I've found the book and will try to read it in time. Good to see you on the forum.

Re: Lachnum mollissimum

Thanks for looking into this Paul. My material all had white hairs early in development. Later the hairs close to the edge of the disc remained mainly white while a yellow blush, that deepened to a definite yellow, developed on the majority of the hairs. There was never the vivid bold yellow in many...

Nettle stems

I'm still working away at my nettle stems and they just keep giving! I've found some perithecia with very stout, conical necks. The epidermis has already fallen away but they are still buried in the nettle stem. The actual perithecia are circular but very flattened. Asci are long and narrow, totally...

Lachnum mollissimum

I've just keyed out a discomycete on dead fennel stems using Fungi of Switzerland vol 2. It keyed easily to Dasyscyphus mollissimum - now in Lachnum? The original descriptions for this fungus only describe white hairs. At maturity the hairs were bright yellow as described in FoS vol 2. Can anyone ad...

Re: Periconia species

Have now found one of the Periconia species on nettle. Periconia sp 20-101 b - jpeg.jpg There is definitely a septum at the base of the 'head' and possible signs of branching or spore chains at that point. Periconia sp 20-101 c - jpeg.jpg Periconia sp 20-101 d - jpeg.jpg Not sure whether this is P. ...

Re: Need ID on possible fungus. New mushroom enthusiast

I've never seen Equisetum arvense when the spores are ripe. I expect they looked exactly like a cloud of spores from a puff-ball. Brown?

Re: Periconia species

I've just checked and I have recorded this on 15 different species in Yorkshire. It is most common (or commonly reported) on Urtica dioica and on a range of umbellifers - especially Heracleum sphondylium . Thanks for that reassurance, Chris. Fennel sounds like a likely substrate and the microscopy ...

Re: Periconia species

I think I've just found Dendryphion comosum again but on a dead fennel stem this time. According to the FBGI website entry, the fungus appears to occur on a wide range of herbaceous stems so this is probably right. Few spores present this time and all 3-septate.

Re: Periconia species

Thanks, Chris. I'd forgotten that Periconia species have globose, single-celled spores. Thanks for the ID and the link to the FGBI website. I agree this fits perfectly. The sizes are in the right area as well. Although I can't measure at the moment, I've got a sense of size based on seeing things I ...

Periconia species

Hi everyone, I'm hoping the forum community will be able to help me. I'm shielding family members in mid-Wales and have my microscopes with me but no means of measuring spores and few books. These are all in Surrey! I've found what I believe to be a Periconia species on dead nettle stems. If I remem...

Re: Fungi on lichens

There is an increasing amount of interest in lichenicolous fungi. Heather Paul and I are setting up a small exhibition today at the BLS AGM. I think a separate page would be great. Illosporiopdis christensenii is quite common and more specific to that nitrogen-rich lichen community dominated by Xant...
