Thank you UWE. Agreed - I was reading about the species and its spores has amyloid ornamentation. == Mushroom25

Thank you,
I also have an update (to be confirmed) that I marked on my XL that I saved a ex-siccatum specimen. Maybe it is useless if they collapse but worth a try. I check your post

I include this example with 5 spore measurements only so that I keep things simple.
As you see the smallest spore is 6.9 and the largest is 8.2 yet Piximetre ranges the spore sizes 6.2-8.7 and I think the extra 1um (0.5um per end) (c. 18%) is a bit too much erroneous. Should it be something like 6.9 [7.1; 7.7] 8.2 ?!?! I never thought about but when I saw this I was wondering....
6.93 4.87 7.08 5.15 7.89 5.37 7.12 5.58 8.18 5.26 6.2 [6.9; 8] 8.7 × 4.7 [5; 5.5] 5.8 err Q = 1.2 [1.3; 1.5] 1.6; N = 5; C = 95% Me = 7.4 × 5.2 err; Qe = 1.4 -
Thanks Wolfgang. I remember it did not sporulate and when I carried out the pileipillis test I was careful to extract the outermost layer. My fault that I did not carried out a good job on the micro (Images crap!)
It us a very strange species and this year I go and search it again (know the place to go) and follow the tape-method which I like and usually I use it on Penicillium spp. and moulds! Would a diluted drop of Phloxin or Congo red help ?

Second opinion is Hygrophorus pseudodiscoideus var. Cistophilus Bon & G. Riousset 1988
But not matching very well in my opinion

If there are experts who study leucopaxillus / Clitocybe I have found this interesting species Under Cistus monspeliensis, here in Malta. I have tentatively identified it as Leucopaxillus paradoxus for its gross physical characters (robust habit, browning areas in pileus, thick stem, dry chamois-like texture, taste above-average bitter, lamella cream-caramel) and somewhat the micro too: Cheilocystidia not observed, spores large about
7-8 µm15.5 x 7.5 um. Unfortunately, I had not much time to work on it as I collected other fungi which I gave more priority. I read that this species was recorded under pine and oak ... so maybe it is host-variable. The appearance is very matching. -
I was wondering if at least we can give it a genus name: Cystolepiota sp.

Good Morning. From my archives of unidentified fungi, here I am showing a tiny fungus, barely 4 mm tall and 2mm wide growing on decaying bark of Ceratonia siliqua (carob). Micro is not available since I have neglected this collection to spend time on others. It can be an abnormally small fungus of some common species, like a Psathyrella sp. (melanthina?) or whether it is the normal size of a fungus that I don't know at all !!! In desperation, I tried googling 'tiny brown mushroom' but I got a bunch of Panaeolina, Conocybe and Mycena and unrelated searches. == twitch

P.s. the images of your micrographs should be cropped to out give more detail, like Steigerwald mushrooms image

I find this post interesting as I was working with a species of the grisinea group (under Qurecus ilex) in calcareous soil, resulting in a parazurea (or orchospora?) which had a rather colourful spore print (not cream or magnolia, but close to the flesh of a peach (ochre in English), strong but short reticulations and much dull colours of the pileus. So what I am trying to tell you is that u can exclude parazurea.

I am seeking help for a fungus (only 2 specimens in situ) on decaying wood (Carob branch) in a damp habitat. It was very small, with its pileus about 1 cm across and stipe 3 cm tall. Pileus (and less so the stipe) was covered with a fine felty (tomentose) coat smf the margin was finely appendiculate. The problem is that its microscopy was boring (or unsuccessful
)First of all I could not detect good spores , yet I think they are small, 3-4um rounded to broadly ellipsoid bodies. The cystidia if present are not specialised and maybe I was seeing basidiomes. The only successful microscopic feature was the pileipellis, intricate hyaline elongated parallel-running hyphae that are smooth and quite long, terminal cells unspecialised too. I think I have seen clamps in the pilepellis. (see image 8129). This is just my interpretation of what I am seeing and maybe wrong, but the physical characters might be good enough
-
What would be the species name of the 'Rotfuss' ? Xerocomellus chrysenteron ?
-
Just wanted to say lovely photos both the macro and the micro (I am just amazed at the clear background too!) . I scroll back to see them another time! Cheers
-
He did but with handshake
.Another option a I told him is that the young specimens had remnant veil and got lost with time-transport and hence his specimen might as well be a Coprinopsis.... but for me the pleated shape of the pileus with grey furrows and tawny-brown ribs is indicative of Parasola! -

I received an exsiccata collected on the 20-Sep-2021 from a close friend/botanist who found it in a garden and growing close to a stump of a small tree. This was growing during a warm season here in Malta. After initial examination, I am sure that it is a Parasola species. However narrowing to species level is quite uneasy.
First of all, a strange character is the presence of pubescence especially at the base of the stipe (I am used to glabrous stipes for Parasola). Next the pileus lacked the typical thick-walled setae (see images) but there was some kind of hyphae forming free fibrillose tufts on the pileus. The pileus was ribbed, with the ribs being brownish and the furrows being grey. The exsiccata has lost its basidia and most cheilocystidia since the edges had eroded/deliquesced, but I managed to see two large spherical bodies which might represent cheilo-or pleurocystidia, but since being globular, they might be something else. The pileipellis consisted of not very long rectangular to cylindrical hyphae, with truncated ends, sometimes a small branch (foot) and with some pigmented (?) incrustations. The following sizes were measured:
37.1 [56.4; 75.8] 95.2 × 12.6 [17; 21.5] 25.9 µm
Q = 1.5 [2.8; 4.2] 5.6; N = 9; C = 95%
Me = 66.1 x 19.3 µm; Qe = 3.5
The spores are ovoid or almond shaped (depending the plane of view) with a distinct germpore
7.4 [8.8; 9.3] 10.7 × 5 [5.7; 5.9] 6.6 µm
Q = 1.3 [1.5; 1.6] 1.8; N = 40; C = 95%
Me = 9 x 5.8 µm; Qe = 1.6
Caulocystidia or hairs looked as elongated shortly-cylindrical hyphae
After spending considerable time researching, I am seeing P. lactea and P. kuehneri as the best options especially for the small size of the spores.

Yesss!!!! I found it - does exactly as I wished
Thank you again!

Hi guys, a quick question. I wish a handy shortcut link (or two) that will list for you all the posts you created (and a second of all the list you participated in) for easy access. Maybe this already exists and I am not aware of it. I guess it would be in the member profile area, or even in the title bar!
Thanks and well done for this precious forum and the wonderful experts and friendly mycophiles/contributors.
Steve

Distribution very south and north african!

This should be Xerocoprinus arenarius in a grassy patch in a garigue/steppe habitat in calcareous soil. Note the root and the large pore in the spores. Dec 2020, Island of Gozo, Ma lta
13.8 [15.4; 16.1] 17.7 × 8 [9.3; 9.8] 11.1 µm
Q = 1.5 [1.6; 1.7] 1.8; N = 31; C = 95%
Me = 15.8 x 9.6 µm; Qe = 1.7

Hello Steve!
That was exciting to follow from the first find till scientific publication. Congrats!
Thanks for your kind words - yes like a diary!

Dear friends,
I and my supervisor have just published this paper about Cortinarius ayanamii, an understudied species from the Mediterranean region forming mycorrhizal association with Cistus monspeliensis (and C. albidus) corresponding to the first Cortinarius for Malta. I think here is the right place to share. Many thanks to Giuseppe Venturella, Uwe Winkler, Pablo Alvarado and Dimar Balint who were involved in this paper.

I measured another set of spores with the following results:
10.1 [11.4 ; 11.9] 13.2 × 5.6 [6.5 ; 6.9] 7.8 µm
Q = 1.4 [1.7 ; 1.8] 2 ; N = 41 ; C = 95%
Me = 11.7 × 6.7 µm ; Qe = 1.7
On Inocybe.org (well done for the work) I read :
Spores up to approx. 12 (13) µm, often drawn out at the apex
I did not manage to PM you (I have photographed the dry specimens) so if you want to send me an email: info [at] malta wild plants .com (remove space and brackets) I can comm re sending samples
