Bryoscyphus sp? on moss
François Valade, 30-03-2013 21:25
François ValadeHello
A 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

Re : Bryoscyphus sp? on moss
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
Prends contact avec JPP, il doit avoir tout gardé.
Je crois qu'au regard du tractus il était parti vers les Calycinella.
Mais Calycinella inconnu.  

Très chouette en tout cas.
Je sais où le retrouver s'il le fallait.

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).

Re : Bryoscyphus sp? on moss
thank you Zotto. Yes IKI directly blue.
Mila told me she knew the place well, so I think that new fresh collection is possible.
I keep the exsiccatum for further investigations.

Re : Bryoscyphus sp? on moss
Hi,

last year G. Bauer sent me photos and material of a similar fungus growing on Lophozia in the Bavarian Forest. I have not been able to find a name for this species either.

Attached are pictures taken by G. Bauer and his description (translated).

Best wishes,
Gernot


on mossy granite rock.

Moss: Lophozia (according to Dr. Oliver Dürhammer possibly L. ventricosa)

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


Hairs +- straight, smooth

Conspicuity: in tap water or aqua dest. some apothecia change their color to pink, in KOH they immediately turn wine red.

Re : Bryoscyphus sp? on moss
and here are my photos of the material he sent to me. Unfortunately it was immature. The ascospores showed strange deformations, maybe it's a Helicogonium growing parasitically on this species.

Re : Bryoscyphus sp? on moss
Yes, Gernot, I forgot that this one on Lophozia might be different from that on Nowellia.

Now, here is a nice drawing by Bernd Fellmann on such a Lophozia collection by Günter Bauer.

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

Re : Bryoscyphus sp? on moss
Zotto I can do it. I has to put an apothecia in a 5% KOH drop, right?
Hans-Otto Baral, 31-03-2013 22:55
Hans-Otto Baral
Re : Bryoscyphus sp? on moss
or put a drop of KOH on an apothecium. I did not do it myself, I only realize Bernd's note

But Alain, are you sure with Pleurozium? Your photo suggests a hepatique, perhaps Lophozia?

Re : Bryoscyphus sp? on moss
Zotto,
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.

Re : Bryoscyphus sp? on moss
Alain: do you also have micros for your find? And was Pleurozium also present there, or was that a different collection by JeanPaul?

Re : Bryoscyphus sp? on moss
Hi Zotto,

the record on the 2 bryo is obly one record. I sent a piece to JPP.
Here are somes pictures, on both.
I rember that there also was a black disco  with Capronia spores-like.

Re : Bryoscyphus sp? on moss
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.

Iki were BB without KHO pretreatment. The micro agree with François pics


Apos first golden yellow becoming pinkish. Reaction  koh on apos no tested.


I join micro and  Alain photo with apos on Hypnum cupressiforme with curved leaves.

Re : Bryoscyphus sp? on moss
If needed, I can also ask Günter Bauer to collect fresh material. The fungus seems to be occuring on this location every year. 

It's nice to have data of several finds now! 

Best wishes,
Gernot
Hans-Otto Baral, 02-04-2013 20:29
Hans-Otto Baral
Re : Bryoscyphus sp? on moss
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....

Re : Bryoscyphus sp? on moss
Oh, yes, now we have the following situation:

- Francois' and Alain's finds on Pleurozium (etc.?) react IKI BB

- Lothar's collection on Nowellia reacts RR

- G. Bauer's collections on Lophozia appear to be RB after Bernd Fellmann's statement.

I need to check Lothar's specimen whether it turns pink in KOH. Hope that further differences exist between these...

Hi! I am quite certain that I have this yellow species growing on Hypnum cupressiforme from Norway. Reddish discolouring in KOH, spore shape and size, K+ reaction etc. all match.  Did you ever arrive at a conclusion regarding this?

Re : Bryoscyphus sp? on moss
Indeed an ITS and LSU sequence now exists of Enrique's sample ERD 6988. Its placement is difficult, however. LSU Blast gives with 96-97% Urceolella crispula & Calycina populina, ITS Blast gives only uncultured, nothing with a name.
