Interesting Coprinellus/Coprinopsis/Parasola and ...

[SheffieldLass]

I've decided to do a new thread to include the other interesting Coprinus species I found the other day as well as Coprinellus angulatus. It's looking to be a very interesting site for the 'Coprinus' genera.

As promised, the macro photo of Coprinellus angulatus:
Growing in wood ash
with the distinctive spores.

Also growing on a burnt willow stump in the middle of ash pile was a small Coprinopsis echinosporus, which also has very distinctive spores, warty with a waist just above the very large and prominent pore.




Then just a bit further along, close to where I've found a few Coprinellus flocullosus, was another interesting find - I'm pretty sure this is Coprinellus subimpatiens, but would like confirmation/other suggestions.



It has a hymeniderm cap, with long pileicystidia:
Hymeniderm at 10x
Pileicystidia

The cheilocystidia are both globose and lageniform, which separates it from C callinus which only has globose cheilocystidia, or just a very few lageniform.


Spores (10.9) 11.2 - 12.7 (13.4) x (5.8) 6.3-6.9 (7.4)um Qav 1.8. This size could fit either C subimpatiens or C callinus


Basidia 4 spored


There were also a lot of Parasola around. Turned out there were not just one species but three . I've learnt to not assume they are all Parasola plicatilis, so they go straight under the microscope. In fact amongst these were the first P plicatilis I've ever found ...

The first was right in the middle of a muddy path, in bare soil, under ash and sycamore. It did look a bit different to the usual Parasola, slightly redder, and not in the usual grassland habitat. The small spores and habitat place it as Parasola kuehneri.


Spore size (9.7) 10.0-10.9 (11.3) x (6.7) 6.9-7.5 (7.7) x (5.7) 5.8-6.6 (6.9).
Average 10.4x 7.2 Qav 1.4

These are a bit larger than the quoted size, but fit better P kuehneri than P plicatilis, and when put side by side with those of P plicatilis at the same magnification, same set up, clearly smaller.

Then there was also P schroeteri, with very fat heart-shaped spores. I couldn't tell in the field P schroeteri and P plicatilis apart, or at my desk either. But being over zealous I decided to look at both under the microscope expecting them to be the same, only to discover that they weren't. Both were in a grassy area.

Parasola schroeteri spores
(10.2) 11.0-12.1 (12.3) x (9.0) 10.0-11.0 (11.3) um
Average 11.6x 10.5 Qav 1.1


Parasola plicatilis spores
(10.4) 11.0-12.7 (14.1) x (8.5) 8.8-10.1 (11.1) um
Average 11.8 xx 9.4um, Qav 1.3

I've put all three one above the other to compare directly -

Top P kuehneri, Middle P plicatilis, Bottom P schroeteri


I'll put the other non Coprinus on a following post as this might be getting close to the picture limit.

There were also a couple of yellowish fungi with slightly pinkish stem and a very pleasant, fruity sort of smell, in wet moss alongside the damp path, under ash and sycamore, very close to where P kuehneri was found, I hadn't a clue what it was, but the spores gave away the genus straight away. Entoloma

With that colouring it wasn't quite so difficult to nail to species level. Entoloma pleopodium



Oh, and those Pluteus with dentate veil remants .... ... well, seems there is only one species of Pluteus with a veil, derrrrrr .... it was the pinkish grey gills that threw me. Psathyrella candolleana ... can't believe I made that mistake, particularly as I found them there a week ago, and at another site too, only they were more mature and I recognised them instantly as Psathyrella ....

Also the orange discos on the ash pile - Anthracobia melaloma. Panaeolus cinctulus in grass, Marasmius rotula, and masses of Tubaria conspersa, and a clump of Gymnopus confluens.

So not bad for a short evening stroll. I'll be watching that site closely, it looks a good one,

I was about to write - had you not ruled out E. icterinum? when I checked and . . . . .

one of my finest moments on a BMS foray was when I was looking down my microscope (probably at a dematiaceous hyphomycete or some other real fungus) and someone came up behind me and said "have you any idea what this could be?" without raising my eyes I said "Nolanea icterina" (as we were then calling it) ah . . . . (such moments were of course few and far between!)

I told you that the Scarborough area would be rewarding, didn't I Melanie?

You've obviously got a good sense of smell. I've never knowingly smelled pear drops, we weren't allowed sweets as a kid, but I seem to know what the smell is ....

And, yes, the environs of Scarborough do seem to be up to scratch . What is more there are good spots right outside my front and back doors. I've even got a lawn that has been dotted with fungi for months (though nothing special there, yet, though). This particular site is within walking distance (though I do have brave a big bull in a field to get there by the direct footpath) or else divert past the Bronze Age burial grounds (which is a good excuse to avoid the bull as it is turning out to be another good site). Though I'm still after some good unimproved grassland with open access ....

That is interesting Mel, as all of the E. pleopodium that I find have scurfy, dark stipes as opposed to the Psathyrella type stipe that's exhibited by your specimen in that thread.

Here's an example of one of mine;



Maybe the scurfy stipe is a feature only in immature specimens.

What do you think?
