This should be Eryphise heraclei. Always found on Foeniculm vulgare (!?!?) in October, even if there are many other Apiaceae species in the wild - although in October many annual species are germinating out.

This should correspond to Xerocomellus redeuilhii (confirmations/disagreement always welcomed), seen a few days ago here in Malta. It was growing under Quercus ilex. Is it recorded in Germany ? The literature says that it replaces X. dryophillus which should be confined to US.

I have found the dried specimen (8mmin size!) and I have the following new data:

• Gills free from stipe and drying to light-brown colour
• Pilleipellis tomentose, trichoderm of sausage-shaped hyphae, sometimes with a pointed tip, clamp junctions observed
• Basidia slender and small with barely visible sterigmata, approx 20-25 um long
• Spores very small barely visible, possibly liberated in groups of 2, 3 or 4s, pip-shaped and only about 2.5 um long
• Cheilocystidia not observed, but not sure if they have been destroyed during drying/rehydration
• Pleurocystidia null

Dear friends

After a hard day of work and part time and house maintenance, I am finally to my escape world of fungi and the kind people in this forum. I have measured the spores and this is the result:

6.4 [7.5; 8] 9.1 × 3.2 [3.7; 3.8] 4.3 µm

Q = 1.8 [2; 2.1] 2.4; N = 41; C = 95%

Me = 7.8 x 3.8 µm; Qe = 2.1

Hi,

did you measure the spores. I would check Lepiota grangei or L. griseovirens.

- Lepiota grangei is said to have spores> 10 so it can be excluded

- Lepiota griseovirens is matching nicely - spore range OK, slightly swollen pileipellis

Hi steve,

I think that could be Lepiota elaiopyhylla, but I'm not sure if the spores fit.

- Lepiota elaiophylla has a very evident yellow tones and is said to grow in green houses?!? I think it is not the one. The yellow tones in one of the pics is because of a bad AutoWhiteBalance when taken with flash at home and drying out. The true color of the fresh fruiting body is more whitish.

Thank you Stefan, Harald and Oehrling for the tips

Hi,

you found an interesting one. I´m a little bit confuses about it. Its a pity that you haven´t better photos of the fresh Specimen. Are you sure that the pileipellis is really a cutis? Im not sure about this in your pictures of the pieipellis.

Best regards

Stefan

Thanks for replying. The basidiocarp was found and photographed by a colleague and he handed the dried specimen. I am sure that I peeled carefully the outermost layer of the pileus. I can try again just in case I was day dreaming. Also the pileus was clean hence no mould contamination. I still have the specimen if someone wants to have a look.

Here is another unidentified small pale mushroom with contrasting scales on the pileus and dark punctations on the stipe. I think there was/is a ring but got damaged or eroded away. Pileipellis a trichoderm. Clamp junctions were observed. In a phrygana associated with Cistus monspeliensi (or less likely Thymus capitatus). I was guessing about Lepiota, but which species I don't know. In Crete, Lozoides and allies records a number of fungi associated with Cistus, amongst which there is Lepiota locquinii, L. farinolens and L. sublaevigata.

Just a question - Are all Asterophora species parasitic ?

Happy birthday Pablo and thanks for the previous helping posts to my ID of fungi.

Hope you had a good day

: D love the answer!

Yes, in an upset mood !

No.1 I opt for Agaricus section minores for the small size, no yellowing, simple ring.

Then you need microscopical examination, scent and spore sizes...

(PDF) New data about Agaricus (Section Minores, Agaricaceae) in Bulgaria

Leucoagaricus maybe? I presume the gills did not darken.

I. familiar with L. leucothites , compare with it, as it looks a bit alike and it is a first-fruiting species in the year. But from photos only, other species can be considered (and some white mushrooms are toxic!)

Same thought of LG Ulla (Hygrocybe 100%) though I would say conica s.l. as there is a small group of closely related species (e.g. H. singeri). The vividly coloured Hygrocybe will darken like soot when old.

If u can handle Spanish:

The one in the video is sordida (smaller, thinner, less robust, little/weak violet hues)

B.t look also here

Lepista sordida vs. Lepista nuda

Lovely photos gosh! Tubaria 100% and I also opt for T. conspersa. T. confragosa is darker and I would exclude safely

Hi, I am no expert, but have you considered/compared with Peziza vesiculosa?

The blisters, colour, size, and irregular shape fits

I don't know, but is there a bit of similarity with Asterophora?!?!

Hi, I have checked again the lamellae using a slightly different mounting technique. Lots of details has been preserved, and I can surely see basidia, and spores that are immensely variable in size and abundant. There are also some hyphae that are possibly cheilo/pleuro cystidia. I post everything here!

Uwe and others who are interested in this fungus, I had time to carry out the examination of the pileipellis. Many parts did not preserve well, but I could see a trichoderm of wavy or almost straight cylindrical hyphae, hyaline, with terminal cells having a very obtuse or truncate ending, and I could not see any clamp junctions.

Zitat von Cortinarius

thats strange, your sure you measured the spores with 400x and not with 1000x ???

I have no idea which white fungus has such large spores.

BR
Uwe

Yes, I was also puzzled. I had in mind this strange thought of some sort of Asterophora and we are seeing Chlamydospores ?!?! However this is a parasitic genus right?. I can redo the spores but I am absolutely sure I was under x400. Spores from a contaminant fungus during dehydration is also possible, but again... low possibility.

Here I am back after finding the ex-siccatum and examined again the spores more carefully under Melzer and Baral Iodine (a stronger version of Lugol's)

1. I think they are inamyloid

2. The spore size is larger than in the first examination, and they average 15.5 x 7.5um.

This large size of the spore might be helpful. Are we still in Clitocybe with these large spores? What about Lyophyllum (Ossicaulis or other genera?) Which like to form fused stipes!

Hi, I did not on that occasion, but I have one from another foray from the same place:

Marasmius corbariensis, decaying leaves of olive tree in a damp area, 8/10/2021, Malta (Gozo)

My first encounter of a fungus for season 2021-2022 after 5 months of very little rain. The season begins
