Thank you, Shrumz, I went on Panaeolus for the dark gills with a white edge. Unless this is again Psathyrella panaoeloides (but I never seen that so dark like this).

Dear friends, can you help with this beautiful slender mushroom. At first I thought it is a Conocybe but then I saw the white-edged gills hence it must be a Panaeolus sp. It was growing on detritus (leaf litter) or broad-leaf trees (Pomegranates)

Thank you Wolfgang and Benjamin.

The mature specimens truly had dark-coloured lamella (the first images were teenagers!). The sparse grouping of the basidiocarps (not solitary) is a habit that also favours Tubaria sp. Spores were smooth.

With your kind comments I keep the label of T. conspersa.

Thanks for your valid opinion. Cortinarius sl are very rare in Malta where only 2 species recorded: C. castaneus and C. ayanamii. The first one is close but not pilose as much and I exclude.Should one expect a ring or a trace of a ring, at least in the young specimens?

Still, I am seeing something closer to this:

Tubaria conspersa 1 [ https://www.alamy.com/the-felt…photo-image401818201.html ]
Tubaria conspersa 2 [ https://https//www.mykologie.n…tem/370:tubaria-conspersa ]

Tubaria conspersa 3 [ https://www.fungi.org.uk/viewtopic.php?t=827 ]

The egg-shaped spores are also matching.

Seems to be a Telamonia...

I have photos of this fungus from an old collection which I think it is is Tubaria conspersa (or at least Tubaria sp). I dont have an micro photos except some not-so-good image of the spores. Gross morphology is there but maybe there are better option. Thanks in advance if you can help.

Spore print rusty brown

I concluded on C. macrocephala

Melzer's key provides further support to this. The spore size of radiata are smaller and C. cinerea has a basal root which this collection do not have.

Good weekend

Marcel , thank you so much!

I had these but I think I had an older version (2017).

Good day

Either macrocephalus and lagopus....

Hello, Manfred!

It is definitely an impressive sight.
Even if the distinction here is rather trivial: Andreas also has a real >Ink Cap Key< on his website , which can do much more than the key in the large mushrooms.

LG, Pablo.

May he rest in Peace He was so much helpful and seemed a kind, happy go lucky guy.

Bernd Miggel have a look at some messages re yr post

Found on a pile of dung (cow most likely) mixed with straw

Spores:

(13.1) 14.2 - 15.9 (16.7) × (8.3) 8.6 - 9.5 (9.8) µm

Q = (1.5) 1.6 - 1.7 (1.8) ; N = 17

Me = 14.9 × 9 µm ; Qe = 1.7

Shape: Elliptical-ovate

Oil bodies: Not present or nor observed

inamyloid, smooth, small germinal pore , rather central

Cutis of rectangular hyphae, sometimes with rounded or attenuated ends (40-)62.4(-80.1) x (12.8-)20.4(28.9)um, hyaline, thin walled, not pigmented

Veil composed of cylindrical hyphae, mostly straight, variable in size but uniformly arranged; (24-)43(-62.4) x (9.3-)13.3(18.3)um

Only a doubt on C. lagopus actually....

Dear all, I have passed from this situation myself that is - C. granulata or C. theleboloides ??? --- and with lots of frustration, sometimes.

I think Moravec (2005) also got into this situation and he dealt by describing var. (or forma) glabra of C. theleboloides , which solve the problem when having a theleboloides with few scanty hairs at the flanks of the apothecium.

P.s. why there is a cross behind Nobi - hope not what I am thinking about

Dear Bernd, I don't know if you are still around, but I was working with a Cheilymenia recently which I identified as C. theleboloides. I am writing to note that the color of the asocarps were initially yellow when young and then they became orange when I revised a 5 days later (and the ground was more dry). The spore striation, habitat and spore size is very important to identify. In Congo red, the striations won't show and in Lactol Cotton blue you need a big effort (or a big microscope) to see it. The hyphoid hairs look like C. Theleboloides except the split hair in yr image (maybe an exception) but the apothecia of my finding were generall larger, ca. up to 8mm.

Hello Matthias,

Sorry for late reply. Actually I am back on track as Coprinellus sp for this finding, rather Psathyrella. Your suggestion fit several characters esp. in the microscopic aspect, but hmmm... the macro comparison is not that very convincing coz my specimens have this tawny (brown) colour whereas the cap of C. hiascens is mouse-grey Although I seen images having a browner colour on the net.

What is so strange with this collection is the lack of deliquescence and the production of few spores observed in all specimens, where the gills remain pale to moderate brown. Coprinellus sp. are usually black and show deliquescence. Another thing is the lack of pileocystidia in the cuticle (or did I miss them ?!? )

I see if I can send it for molecular determination in the future, but it is a very odd finding.

Hi Marcel, Yes, that makes more sense! I dont know why I neglected this Genus (the animal excreta maybe?!) although the plicate cap (deep furrows) and small size are features of Coprinellus s.l.

hmmm... the more I look at this fungus, the more I am puzzled.

The stem is brown, not much as many Coprinellus which is often beige or white. The spore cover is minimal, indeed the gills are brown not dark-brown / black

I was wondering I I had a mixed collection of two species but it is clearly shown that the lamella are forming the black spores. The gills are then widely spaced apart (most Coprinus are densely packed). The spores however are typically of a Coprinus s.l.

Hello, I am a bit stuck with this finding from the Maltese islands of a Coprinellus sp. on damp soil mixed with farm animal bedding (= rich in nitrites), which gave me an indication around Coprinellus disseminatus, but the micro does not match because the spores are too large. They have a large central pore.

(9.7) 10.1 - 12.5 (13.4) × (5.3) 5.7 - 6.4 (6.6) µm

Q = (1.6) 1.7 - 2 ; N = 21

Me = 10.8 × 5.9 µm; Q = 1.8

Veil elements spherical

Cheilocystida present, not abundant (maybe old specimen) - Lageniform to subutriform, approx. 60 x 20 µm

C. micaceus maybe ?? but not happy, look the gills they are widely spaced (C. micaceus dense)

Mellieħa, Malta, 11-10-2024, under Pinus halepensis in damp soil close to a sandy shore lining brackish water.

Yes it is a possible cause, I can spray some contact cleaner inside the potentiometer.

It can also be in the PSU, current not being delivered at high setting.

Thanks for your opinion !

Stephen

I have a 40 year old Zeiss AxioLab RE microscope which has been my working horse and faultless for so many years.

Now I have this fault, where when I increase light up to about mark 5 it works fine, but as I increase the power more (to mark 6), the light dims to about level 2. It is not a big issue but maybe it is a known fault and I can inform my electronics friend what needs to be replaced (leaky capacitor in PSU ?)

Thanks

Can you put / write the link again without https://

Stick does not work and the pasted url is 'truncated' so it shows

https://bolioptics.com/blog/ho…iopters-to-magnification/

Here, I want to present an interesting early-fruiting species that I only have (for now) macrophotographs because I saw this in a public garden and was not prepared for collection (also images from my mobile) but I am sure it is a Leucocoprinus. Usually these early-fruiting yellowish basidiocarps in artificial soil are L. birnbaumii but this one was different in:

1. Not in compost / peat or pot but more 'outdoor soil'

2. Smaller, thinner, "fragile" - the ring falling off

3. Colours are definitely paler

So then doing further research, I am thinking that I found Leucocoprinus fragilissimus. The only thing is that from many images this species on the net, it seems to have a narrower, tooth-pick like stipe (but some shows similar features).

I can do a collection tmrw, hoping they are not destroyed.

In the image below I slightly enhanced the colours

I always experience poor spore amounts with the small white Phloeomana / Hemimycena ( / Mycena) spp. that I never even think of attempting a spore print. I should do amyloid test from now on, and better observations on the pilleipellis. I look forward this season to study more collections. I think I have some one or two old findings yet undetermined, which I may discuss in this group.

Thank you for your help and correspondence. I will insert a note Det. by Matthias ??? (what surname pls? - send me a private message if you wish to keep it secret from public domain) Btw Happy birthday tomorrow

Thanks for discussing this and sharing your observations. I agree about not using the extremes of the diopters. Very strange about yr last comment too.

p.s. The link says forbidden ?!
