Lambertella sp
Valencia Lopez Francisco Javier, 01-09-2017 00:58
Hola a todos.
Presento estos ascos recolectados estos días en hojas de Hedera hélix en un canal de riego.
Apotecios de 3mm los de mayor tamaño, himenio de color ocre con pelos en el margen, parte externa del mismo color, estípite con numerosos pelos blancos y la base ennegrecida.
Los elementos microscópicos creo representarlos bien en los adjuntos.
En un principio y antes de su estudio microscópico creía que se trataba de Lambertella tétrica presente también en la zona en hojas de H. hélix, pero la forma esporal la separan perfectamente.
Alguien podría ayudarme con la identificación??
Gracias anticipadas y un saludo a todos.
Curro Valencia

Re : Lambertella sp
I think also it is a Lambertella, but have no idea of a species.

I tried Zhuang's 1996 key but do not arrive at a species.

What is the apothecial diameter?

Re : Lambertella sp
Zhuang does not have L. tetrica that grows on Hedera helix (Dumont 1971: 144). But ascospores do not fit by size and shape (much larger in tetrica and asymmetrical).

Re : Lambertella sp
Yes, we have wonderful photos by Raul of this L. tetrica, totally different, big oil drops in the long and narrow spores.
Valencia Lopez Francisco Javier, 01-09-2017 17:31
Re : Lambertella sp
Muchas gracias por los comentarios.
Efectivamente L.tetrica tiene las esporas diferentes, adjunto foto de una recolecta en H.helix en Ronda (Malaga)
Zotto el diámetro de los apotecios es de 0,5-3mm.
La guardaremos en herbario.
Un saludo

Re : Lambertella sp
my copy of Dumont 1971 is very poor, I barely can read his key. Perhaps somebody has a better pdf?

Re : Lambertella sp
In my single page files p. 11 and 13 are bad, anyway readable. 

Martin, ich schicke sie dir per Mail.

Re : Lambertella sp
Thank you Zotto,

I arrive at L. jasmini, known from leaves and fruits of different hosts but not Hedera.

Re : Lambertella sp
Indeed Martin, at first glance it looks very similar.

Valencia, could you please send me your composed photo plates in higher resolution (not the single photos)?

Thanks
Zotto

Re : Lambertella sp
Muchas gracias a todos por la ayuda prestada, comparando los datos con las fotografías enviadas por Stip cuadra bastante bien con L. jasmini.
Un saludo a todos.

Re : Lambertella sp
Valencia showed me further pics and it is now clear in my opinion that the asci are devoid of croziers. Pics attached

Re : Lambertella sp
this absence of croziers seems to be th only discrepance, Dumont speaks of obscure croziers

Stip
Hans-Otto Baral, 04-09-2017 17:05

Re : Lambertella sp
Indeed, I also saw this and I remember that Dumont's statements about croziers are not trustable.
Martin Bemmann, 04-09-2017 17:42
Martin Bemmann
Re : Lambertella sp
And croziers, or just obscure ones, are not implied in his drawings as well.

Re : Lambertella sp
to complete this documentation I attach the original description by Whetzel from 1943.

Dear Valencia, did you observe those branched paraphyses?

Regards
Martin
Hans-Otto Baral, 06-09-2017 13:01
Hans-Otto Baral
Re : Lambertella sp
Thanks Martin!

Whetzel illustrates the apical ring which indeed suggests a sclerotiniaceous fungus, although being a bit schematic. otherwise this concurs with Dumont's drawings.

Zotto
Valencia Lopez Francisco Javier, 06-09-2017 22:59
Re : Lambertella sp
Hola Martin.
Las paráfisis si que presentaban ramificaciones cerca de la base, adjunto foto, también de esporas anómalas dentro de las ascas.
Gracias por los enlaces.
Un saludo.

Re : Lambertella sp
Thank you.

These "esporas anómalas" correspond to the germinating spores as shown in Whetzel's fig. 3.

Martin
Hans-Otto Baral, 07-09-2017 11:28

Re : Lambertella sp
yes, they are overmature spores. And the basal ramification of paraphyses is very normal in ascomycetes.
