I revisited the same population and just collected a few infected inflorescences. I post on a fresh topic in the forum. Bjorne, if you want to follow just look in the respective topic-group where I should post this again. I will have a look at the spores tomorrow

Inquilinus seems to be a more petite fungus with semi-translucent stipe, and a whiter -> whitish-cream pileus ... but closely related of course. I am just confused/undecided between inquilinus and plautus.
Further comments are welcomed!

I am convinced that it is a washed-out melantina. Thanks a lot for your replies!
-
Dear friends, sorry for the late reply. I was inquiring and researching the possibilities based on your kind answers. I have found a closely related species of P. inquilinus which often grows on oak forests, hence a pale form of P. plautus. Could this species be considered? I know usually it is medium brown in color, but paler forms are often documented and met in the wild:
spore:(6.5) 6.8-7.4 (-7.8) x (4.8)5.1-5.9(-7.8)The link above shows strong similarities!
Spore 6.6-7.9 x 5.9-7.2 µm; media 7.3 x 6.6 µm; Q = 1.0-1.2; M = 1.1, as a subglobose largamente ellissoidali, lisce, con apicolo, guttulate

This is also valid for terrestrial orchids! Very nice quote from the mycologist.
Alles anzeigenHi,
nice that you speak English so well.
There was once the saying of an experienced mycologist (who was also familiar with the publication by HILBER): "Everyone who describes new species should be forced to spend 1 year in an oyster mushroom cultivation facility beforehand. Then not every small change is recorded as a new species. "
regards
Peter

If you want this sample and other samples from Malta and sometimes Finland - I will help

Not being any mushrooms around, I am trying to re-investigate old collections. I have found this collection in an oak forest (Quercus ilex) which is beige, medium-small (8cm long, pileus 4.5 cm wide). It had a fragile stipe but I don't think it is a Psathyrellaceae for its spores are subglobular and hyaline giving a light cinnamon-brown spore print (but I am aware of how diverse this family is!!!). Gills free. Cheilos present. No ornamentation on the cap, no smell, no volva, no ring, no bruising, no reaction, very boring! Basidia clavate, x4-sporous. Frequent, variable in size, utriform (45-90um long), pleurocystidia rare or absent. Spores 5.1-7.3 x 4.1x5.9 µm, subglobular-pip shaped. 'Hymenoderme of subglobular to broadly oval, slightly angular hyphae with a very short appendiculate peduncle. If I have to guess, I chose the genus pluteus. I don't have an exsiccatum for further investigations

Hi dear friends,
I. wanted to chare this beautiful species and confirm if it is Helvella leucomelanea.
-
Well done Claudia and many thanks for this forum members and respondents - I am learning a lot!
-
Oh well, yes for the fact that P./C. melantina is very common in Mslta and grows in similar habitat and habit (with spores matching). I forgot that this particular species have pale spores. I did rehydrate the old specimens in 5%KOH before staining and then cleaning in glycerol/KOH mixture. it is a good suggestion, thanks! I will check more images of this species as probably when photographed in situ they were overmature, wet, and weathering (eroding) away. thanks as always !

Section in Lugol's iodine - spores inamyloid
-
The spores are ovoid, hyaline, smooth, with an eccentric tiny apiculum. Guttulae not seen and some are kinda broken, maybe because they are old spores(?). I can see variability in size too (9-12um long). If necessary I can test if they are amyloid.
(8.8) 9.2 - 11.4 (12.1) × (4) 5.2 - 6.4 (7.1) µm
Q = (1.5) 1.6-1.9 (2.2); N = 17
Me = 10 x 5.6 µm; Qe = 1.8
-
Here is the section mount of another gill. The edge does not show cheilocystidia unless they got eroded or destroyed during drying / preservation. Interestingly, there are what looks as subglobular cystidia in the gill face, perhaps corresponding to pleurocystidia (?), The largest being 35x 25 um.
-
The microscopy is pretty disappointing. Pleuro absent, cheilo probably also, basidia not distinct and spores are quite translucent, hence I am thinking that this is not a Psathyrella. I try another attempt and I will also measure the spores.
-
-
Dried ex-siccatum found.
First hint - lamellae become translucid (colourless) when hydrated in KOH. Spore mass colour (spore print) seems to be tobacco brown - just an indication. Now trying to hunt for spores and cheilocystidia
-
Lot of basidioles but seldom defined basidia sterigmata. The few I saw where x 2 (-3). What do you think, do you agree from these photos ?
-
I have another fungus that I am trying to have a clue. I made up my mind that it is a Psathyrellaceae. Interesting is the zonation on the pileus and the its very viscid character. It was growing from a pile of old stems of dumped plants. Maybe wild plants from a nearby field. I see if I have collection for a micro assessment. Any early clues are well appreciated. Thanks!

Hairs at the base of the stipe

Stipitipellis
-
Cheilocystidia or basidioles ?
-
I know that I am asking the impossible here - but I give a try with this frequently occurring Mycena growing on detritus and litter of carob trees.

An anamorph
What is the central brown disc? -
Yes you are right I interchanged the subsections by careless mistake. I will check and probably include the fourth. Thank you so much!
-
Thanks everyone - I think I have to give it a miss as it seems too complicated. The specimens were very small. If some wish to receive a sample let me know (PM or email)
