Re: Fungus Of The Day (One identified fungus only please, with species name in attachment comment and in post)

Psathyrella ammophila Spurred on by recent reports of dune fungi, I went looking yesterday and found several groups. This is a species I have been keen to find for some time but always looked in the autumn. Young specimens have subdecurrent gills which become exagerated when mature and open. Most re...

Re: On Parmelia sulcata

Hello Paul

Many thanks for the identification and for correcting my terminology - and how kind to think I was ever on the scent ...
Feel free to use the images - if you require better resolution, just say.
I have a small piece spare if you would like it.

Best wishes, Chris

On Parmelia sulcata

A lichenicolous fungal anamorph, pycnidia 100–120 µm diameter. Conidia 17.3-23.3 x (6.1-)6.6-8.0 µm.
I looked through known associates that I am aware of but failed to identify it.
Any help welcome.

Re: Hyalorbilia inflatula?

Thanks Chris

I feel I should request Zotto's files from you but will probably need to lie down afterwards!

Re: Hyalorbilia inflatula?

Thanks Paul.

Knowing the extent of Zotto's website, I entered with trepidation ... and with good reason. :?

All the best, Chris

Hyalorbilia inflatula?

I thought this might be Hyalorbilia inflatula, growing on rotten Fagus wood but the spores are a little on the long size.
6.1–8.5 x 0.9–1.2 µm. No bluing in Melzer's.
What do others think?

Microbotryum saponariae

Growing on the anthers of a cultivated species: Saponaria x olivana . Spores purplish-brown, almost globose (Q = 1.1) 6.3–8.2 µm It would seem to be rare in the wild. I've not be able to ascertain its status on cultivated species. Regards, Chris (One I prepared 3 days ago but had trouble accessing t...

Re: Myzocytium netrii?

Hi Paul

The size and shape doesn't fit the data give either. It would be good to see some modern images but I've drawn a blank. Dick's work may have some but I only get to see a few preview pages. I'll just archive it for now.

Thanks and best wishes, Chris

Myzocytium netrii?

As far as I can ascertain, this fungus is host specific to the desmid genus Netrium. Here it has infected Netrium digitus and Netrium digitus var. latum . The latest taxonomy has reduced the genus to 4 species, all parasitic on algae. Sample taken with a 30 microns plankton net through a Sphagnum-ri...

Re: Me again with fungi

Every feature screams Leratiomyces ceres apart from that ring. You wouldn't have an annulus/veil/cortina emanating from the gill attachment. I think this is just a bit of flesh ripped from the cap at the apex. Welcome to the forum. That's a well deduced arguement which I'm in accord with. It does s...

Re: Growing on fallen twig of Picea sitchensis

Hi Marja

Thank you for the thought - as you say, not this species but one I haven't encountered yet.

There are no trees here to get lost in but I'm often seen floundering in keys. :(

Re: Penicillium vulpinum

Hello Paul Please leap in anytime, I'm often floundering ... :) Chris Y tries to keep me honest. My main misgiving with Penicillium vulpinum was that it didn't 'look' like any images I've seen. Perhaps a result of culturing, as you suggest. I must say, from a macro point of view, Penicillium ulaiens...
