Rare species of Lepiota and other genera,

and PIOTR CHACHUŁA[/edit]

Hi, I have to retreat from my first impression of being a Pseudobaeospora because this genus do not produce a ring and it has tubular straight (needle-like) hyaline rhizoids that are not present in the examined material. The other collection is a Pseudobaeospora so that was a different species from the one in this post. So, now I have to fall back to a small Leucoagaricus (or Lepiota?!).

Now this text from Wikipedia is crazy: " Leucoagaricus sericifer is an agaric fungus in the genus Leucoagaricus. It was originally described as Pseudobaeospora sericifera by French mycologist Marcel Locquin.^[1] It is widespread in Europe".^[2]

Well, I have to repeat the micro maybe from a younger specimen maybe something went wrong.

From my archives, here is an organism which I could not make a clue. I have only external images, no micro. I was thinking about some sort of structured mould (an anamorph of something maybe ?!?). Maybe someone has met something similar and can suggest some additional info... without expecting miracles! These were growing on fallen branches of Eucalyptus trees

Thanks in advance

Yes, I confirm that Cyanoboletus pulverulentus becomes deep blue in few seconds (=instantly). Problem with external colours form me is that they vary with maturation and also interspecific variety. Old specimens of Cyanoboletus are really dull and unattractive, young ones are quite more eye-pleasing. Thanks for your explanation Seb.

For my learning ... could the 6th mushroom which stains deep blue be Cyanoboletus pulverulentus? (also an oak lover!)

Thanks

Hello again. I found a few examples of this beautiful Lactarius with a burnt orange pileus and a reddish stipe which gradually deepens to blackish-red at the base. Spores subglobose with reticular ornamentation around 8 um diameter. Sap not abundant turbid (not milk-white) slightly bitter but not strongly so. I was thinking that this is the Lactarius atlanticus but after reading this site:

LACTARIUS ATLANTICUS

two look likes are mentioned: L. serifluus and L. subumbonatus, but I think both are not the same that I have photographed. The atlanticus epithet (hence indicating its distribution is far west) and the dark red stipe put some doubt in my mind... BUT I think I should not look elsewhere and confirm this as L. atlanticus!

Thank you.

Here Limacella is scarce-frequent and I think there is a single species. It is in the whereabouts of L. furnaceae or L. subfurnaceae, but I can't get the right knowledge how to differentiate between, if ever they are really different. I have plenty of material (exsiccata), images and micro-data to share if someone like Mollisia whish to investigate further. The ones I found are almost always associated with leaf/branch litter of carob trees. The smell is really distinct !

At this stage, I am sure that the genus is Pseudobaeospora (family Tricholomataceae) - hence that is already an equalizer
Regarding the species, that is a challenging task, and I try to get as much info as possible, but I already pinned P. albidula and P. calcarea are at the moment the strongest options.

(PDF) Pseudobaeospora albidula (Agaricales) found in the Czech Republic

This paper has an interesting discussion opening to further research and options, from a possible new species that gros on leaf litter of broad leaf trees (spec. to carobs?) because from what I gather, these 2 species prefer to grow on moss.

Then this is also interesting:

Pseudobaeospora paulochroma and P. bavariae differ from P. albidula and P. calcarea in a positive (ie yellow or pale sordid yellowish) reaction of the pileus surface with KOH. Pseudobaeospora terrayi has a mild taste and therefore dif - fers by a pale yellowish greenish reaction of the pileus surface with KOH and by the presence of well-developed suprapellis.

I judge a positive pale sordid yellowish reaction in my specimen (see photo above)!

Some micro images (not much to show!)

good evening mycophiles

This fungus is the same that I reported weeks ago but here it is from a different location:

Small white mushroom, with a tomentose covering

These are the new images taken yesterday.

MACRO:

Small basidiocarps with a tomentose veil, hence tomentose cap and ring.

Gregarious or fused at the base

Lamellae free but very close to the stipe

Taste fungoid-sweet, good and palatable

Scent indistinct

Stipe white, but sometimes greyish esp. after handling

Pruinose-puberulent esp. above the ring

Stipe hollow, inside there are longitudinal white fibres (not sure if it is a characteristic of species)

Base slightly swollen in solitary examples

Ring slowly evanescent, leaving a cottony scar

Spores hyaline, don't stain easily.

4% KOH on stipe forms a faint yellowish colour (with a hint of greenish tones?)

MICRO (quite boring)

Cheilocystidia and pleurocystidia not observed

Distinct feature: Spores 2.0-3.0 um which aggregates in pairs or clusters, pip-shaped.

Basidia 4-spore (I managed to see one!)

Veil (or pileipellis) trichoderm of cylindrical hyphae, a few with clamp junctions, unspecialised

Steve vs White fungus with ring: 0-1 in 2018!

Now I met the same fungus in the same locality and even almost the same date (23/10/2018) and I want to rechallange and try to identify this cute and curious species. I just came from the forray (super tired!) and still have my camera in the bag, but these are the images from 2018. I will document gradually this fungus here. It is small (2 cm) and grow in small clusters, with the base of the stipe fused / connexed. I am quite sure that the habitat is leaf litter of Quercus ilex or Ceratonia siliqua, not connifer ( pine leaves present in pic). Investigation for tonight or tmrw!

To be continued...

Ah ok for the BWB Strange u have that violet tinge, but I have to say that it did not stain the spores very well, so better you buy a fresh supply. It is not expensive. IN my humble opinion it should stain both in acid and in water but it does not work well when the pH is slightly alkaline (unlike Congo red). In pH > 10 or so it will precipitate or form some blackish colour if my memory is still good. Well ... just buy a new BWB and see if u can compare the spores of the same sample

Thank you Tuppie - enigma solved!!! I decrease the temp to 40C.

Good day!

Dear friends. Some years ago I built my own desiccatorfresh with temperature control, light, fan, etc. I wanted to ask if 42-49C is the ideal temp to desiccate fungi in a challenging climate with humidity >75% and warm winter temperatures where infections from moulding parasites are not uncommon. Is >50C to high that damages the hyphae/cystidia? TNX

P.s. I place the fresh fungi inside, and those dry I keep them on the lid while working with them which is pretty warm until I am ready and store them in boxes later on.

I had fair success in my last staining of S. crinitia with LACB - Lactic Acid Cotton Blue (what is BWB dear german folks!). Dont mind my question, just a re-assurance, is yr stain truly cotton blue or cresyl / methyl blue? It has that violet tinge which is not typical of cotton blue which is more pure blue. I applied white balance to yr image and there is still the violet hue evident.

Second point, be sure you focus away from the equatorial plane hence yr focus must be on the surface of the spore. I see thick wall perimeter meaning you are focusing inside the spore. One trick is to photograph a mass of spores clumped together and you will hit a bit of everything focus-speaking. My before-last image (no.5) is for example not focused in the right place, yet the perimeter seems nicely focused

Third, the common S. crinita (kindly confirmed for me by Nobi) has very fine punctations / ridges that are difficult even at x1000.

Finally don't be afraid to experiment with post-editing images (enhancing contrast) - see last image and compare the difference with untouched images.

Zitat von Tuppie

The Americans aptly call such a workshop located in a branch (or simply a place for undisturbed reading) a “she shed”.

Well, it reminded me about the fine interiors of a hobbit home in lord of the Rings

It was a pleasure reading and seeing many (but not all!) Pictures of this long-thread post (15 pp omg!), Especially your study-place and drawings. It seems a quiet place there, something which I start missing badly here in Malta 'quietness' and 'peace'. It is 5:30 am and there are already delivery vans and some cars, a few lorries driving in the street (an its not a highway)

Very beautiful/rustic study with little spoilage of silicon technology... with the only silicon is probably the sand collections. I presume they are artistic souvenirs, but if they are just samples of sand, I can send you some sand samples from Malta and Gozo.

Tanks for sharing this

My diagram from my undergoing thesis in the public

The matchstick is important and sometimes I do not immerse the specimen in water but add drops of water on the cap every 2 (-4)hours. This is absorbed and keeps the basidia happy and moulding events are decreased. I sometimes have poor spore deposits when immersed in water. However, leaving them overnight without water might dry esp. for small-capped (<2cm) fruiting bodies.

Very nice subtle pink colour. First time coming across the genus Pseudoclitopilus and I was wondering why the genus Pseudoclitopilus was created/defined - is it only genetically different or there are morphological differences that characterise it? This looks like a Clitocybe.

P.s. the English translation of the German title reads: " White mushroom. Maybe a bitch ?" lol!

I have bit of experience with Arrhenia rickenii and the first set of images is that species. The second set has the feeling of a galerina so follow the track of our colleague Norbert. The last set is a bit different from Arrhenia rik. and unless it is some odd example, I suspect it is an Entoloma. I never seen anything like 11 and 12 and it is a wow for me 😍

Cap slimy, and scent nauseatic like a cocktail of bleach and millipedes! There was only one specimen around so I did not pick it up. I had a small doubt on Leucoagaricus leucothites! Habitat is more similar to that of the Limacella! Then there is the usual problem between furnaceae and subfurnaceae (!!!) but confirming he Limacella is already a big help!

An amazingly large population of Candellomyces (psathyrella) candolleana (unless it is something else) but the habit and habitat (underground woody roots of dead trees) is typical for the species here. Admins may safely move this post to other categories if it is not adequate here!

Thanks Oehrling. I will report here if I find an answer from other sources. For now, there is nothing else to add, and maybe some Bolete expert like Beorn pass from here and see/reply to this post.

I think it is the same one found on NetFlix (Fantastic Fungi) which I liked to watch and learn although there was a rather long section abouy/promoting psychedelic mushrooms and consumption for recreation. The videos showing fungi in fast motion is truly 'fantastic'!

Thank you Nobi for your comment

I try to photograph the spores with the zeiss phototube for my EOS SLR camera and Zeiss microscope because I have a delivery note that it arrived at the post office. The images above are with a digital camera through the eyepiece.
