Bryoscyphus sp? on moss
François Valade,
30-03-2013 21:25
HelloA small yellow Bryoscyphus sp? on moss, Pleurozium schreberi has been collected in february 2013 by Mila Tanaskovic in Fontainebleau (F).
She gave me a part of her collection and it needs to stay three weeks in the bottom of the fridge to see some spores.
apothecia are stipitate, 1-2 mm high, diam. 1 (2) mm
spores ellipsoid-fusiform, sometime with one septum, OCI low
N= 20 ; 12,3-14,8 x 2,8-3,8 Qm= 4
ascus with croziers, 60-70 x10 µm,IKI +
excipulum textura epidermoidea?
paraphysis filiform, 2 µ wide
In Zotto's dvd (pictures and Bernard Declercq's key), I found Helotium ("Bryoscyphus") phascoides that can fit this collection, but the color is white.
Have you any idea about it?
thanks in advance
cheers
François

Salut François,
Ca ne va pas t'aider mais j'ai déjà une récolte analogue.
JPP pourrait t'en parler, je lui avais mlis dans ses pattes, n'ayant abouti à rien.
Mes apothécies devenaient rose-orange avec l'âge, as-tu observé cela sr cette récolte ?

Re : Bryoscyphus sp? on moss
Hi Francois,
it seems to be difficult to say what the color in a natural environment with daylight should be.
It could be that the color remained yellow because the lack of dayllight (UV) to bleach it.

Re : Bryoscyphus sp? on moss
Exactement le même.
La mousse était aussi Pleurozium schreberi, trouvé le 3-3-2011.
Il était aussi jaune que le tien.
Et j'avais noté pour la micro :
Asques octosporés J+, spores de forme et taille variable, oblongues en général mais je donne une fourchette raisonnable de 13-15 x 3-4.5 µm, guttulées, parfois 1-septées..
J'ai pas mal de photos et d'autres données si nécessaire .
M^me croziers et même paraphyses que pour ta récolte.
Alain
For Stip : it is constantly yellow, like Bisporella.

Re : Bryoscyphus sp? on moss
wonderfull collection! This is never a Bryoscyphus, because that genus has a Hymenoscyphus type of apical ring and paraphyses full of strongly refractive VBs.
Instead, it reminds me strongly of a fungus found on the hepatique Nowellia. I have it in my files in the genus Roseodiscus, though only because of lack of a better opinion. Yours should be the same genus though not conspecific: that on Nowellia has shorter spores an a hemiamyloid apical ring (RR). Yours is directly blue in IKI I assume.
I thought we had the Nowellia fungus already in the forum, but I cannot find it. Here is my plate and a drawing by Lothar (I never saw mature material).

Apos. 0,5 - 1,5 mm, yellow-orange with lighter colored margin; underside light yellow; stipe hardly present; numerous on dead moss.
Sp. (11,5) 13-15 x 3-3,5 µ, partially 1-septate.
Asci 55-62 µ long , Melzers / IKI +, with croziers (difficult to observe)
Paraphyses filiform, septate, branched

Yes, Gernot, I forgot that this one on Lophozia might be different from that on Nowellia.

Resembles indeed that of Francois. I see that in KOH the yellow turns pink! Can you test that, Francois?

I agree with you. For me at first, I recognized Lophozia (or Barbilophozia too).
I remember having sent material to JPP and he answers to me that it was also on Pleurozium shreberi.
In conclusion : Luteodiscus primoaprilus comes on both.

I have difficulties to translate my message since yesterday night
About Alain collection, I called it Calycellina luteorosea. The tractus seems very close to Calycina type, but the new genera Roseodicus Baral is close too.The apos grown on Barbilophozia, Pleurozium and Hypnum cupressiforme. It's not rare when the apos are very abundant, they colonize all bryo around.

So I still do not understand what's the bryo on Alain's photo. Also I assume JeanPaul means that the IKI reaction was RR as on his drawing, not BB?
It might finally turn out that on all these bryophytes and liverworts the very same fungus is growing....

your ascus/paraphysis pics look like being in KOH? Did you test IKI after KOH? Imprtant is to add IKI to water.

Bonjour les ascophiles, je suis très content d'avoir trouvé ce forum mycologique. C'est mon premier post sur ce forum et je ne connais pas encore les conventions- alors n'hésitez pas à m' informer si vous avez des suggestions ou corrections. Merci! Je vais ecrire en anglais parce que ça fait des décennies que j'ai appris le français à l'école. Pourtant je comprends mieux que je parle, répondez alors en français.
Hello,
I found this collection of yellow Helotiales on moss growing on granite rocks 04/10/2023 near Wunsiedel, south-eastern germany approx. 800m above sealevel. As colonized moss on that location was at least 3 different species (Polytrichum cf. commune, Dicranum spec., cf. Hypnum spec.- or Pleurozium?) at first I dismissed the idea of a moss parasite, which usually seem to be quite host-specific. Yet a colleague sent me a link to your discussion here and it looks to me like it is a related species as to what François and Alain showed here. Has "Luteodiscus" been established in the meantime?
Ascocarps were bright lemon-yellow on front and backside, width approx. 0.4-0.8mm. Margin with tiny hairs. Flat/ no apparent stem. Colour changes with KOH 5% to purple-red. Growing directly on "leaves" and "stem" (gametophytes) of mosses.
Microscopically asci were pointed like a pencil towards the tip, porus often excentric, IKI+ (BB), croziers+, approx. 70 × 8µm.
Paraphyses filiform, partially septate, sometimes branched (see pictures). Spores fusiform, yet somewhat polymorph, one end often tapering, multiguttulate, one nucleus. Size from sporecast (11.8) 12.4 - 16.4 (20.3) × (2.9) 3.1 - 3.8 (4.1) µm Q = (3.3) 3.5 - 4.9 (5.4) ; N = 41 (Piximetre, classical formula).
What do you think of it? If you need more details just ask, i still guard it in the fridge.
Thank you in andvance, merci bien
Ingo

Re : Bryoscyphus sp? on moss
Hi Ingo, welcome!
indeed this is Luteodiscus bryophilus as we want to call it. The paper is under work but far from finished.
A small correction: paraphyses are always septate, the septa often difficult to see. The contents are interesting, they are VBs and vary in this species between faintly to strongly refractive. Also the spores contain VBs of low refraction, only those with high contrast are LBs.
As I am preparing a distribution plate I would be happy to include your specimen, of course with citation and acknowledgement. Therefore I need the coordinates. Good would be to better clarify the hosts. I would suggest Dicranum scoparium but I am not good in mosses. The cf. Hypnum is not well visible on your photos. helpful would be to make microphotos of the leaf of this moss.
Now I noticed that your scales of asci cannot be true, I arrive at 100 x 13-15 µm. Perhaps 25 µm is closer to the truth.
You can send me also photos by mail (zotto@arcor.de)
Thanks
Zotto
Ingo Ibelshäuser,
19-04-2023 22:16
Re : Bryoscyphus sp? on moss
Hello Zotto,
thank you for your comment and confirmation of the mentioned species!
I obviously overlooked most paraphyse's septae as I am not used looking for septae, probably I should focus through whole thickness and adjust contrast to find them.
And you are absolutely right, the scale dispayed in the pictures must be wrong. The reason will be that I cropped the images to upload it here and the program I used to imply the scale uses the amount of pixel to create it, (i thought i uses the presets of my lenses) which therefore was not calibrated. I will correct it. Yet the measurements mentioned in the text are correct, as I did them before cropping the picture.
Concerning the host species I am about to take microscopic pictures of the mosses before I will dry the rest for documentation. With Polytrichum I am pretty sure, with the rest not. Maybe I could ask a moss specialist I know for determination.
I would be happy to contribute to your paper and will send you the pictures in full resolution (with correct scalebar) and the coordinates (MTB) to your email.
Kind regards,
Ingo
