Castillo JosebaFotografie esta especie  el martes 17 en una hoja de encina

En principio eran como unas bolitas  blancas   de menos de 1 mm.  al dia siguiente  estaban marrones y hoy estan negras  y con la superficia con pelos.

He hecho algo de micro,   pero no tengo ni idea de por donde mirar

Agradcere cualquier sugerencia

Saludos

myxomycete (cf. Dianema spec.)

Hello!


I think you are at the wrong forum here :-)


Best regards from Lothar

Gracias

Re : Una ayuda
It is a myxomycete, perhaps Metatrichia vesparium

Re : Una ayuda

sorry - but Metatrichia vesparium is looking very, very different (for instance only: it ist stalked and bears some sporocarps at a common stalk, the spore mass is deep red). I aldready made a more likely suggestion (see subject of my last post).

Re : Una ayuda
Hi,

these were picked immature and they never actually developed to normal shape but dried on the way.
The shape and presence of capillitium hints to some Dianema.
But in photo 5 there may be a developing stalk and columnella and capillitium is present.
The colour of spores is darkening -> Stemonitales.
They have often white plasmodium, which turns pink and after that they come darker.

Re : Una ayuda

Hi Marja,


I do not agree. You can see at the pictures that the immaturely picked (yes!) sporoarps had ripened quite accurately before they dried. At least they developed capillitium and spores. Completely unripe specimens of myxos (and it had to be very unripe if I should consider it possible that it will become a Stemonitales) do not have spores developed. So - this is a Trichiales - and Dianema is the most likely I can think of.


Regards, Lothar

Re : Una ayuda
Hi Lothar,

the development did not finish propely. Part of the spores are huge and I have seen that many times with myxos, that have met unfriendly conditions.

The capillitium (photo 6) is very dark brown at least partly (may be lighter at tips?) and branches and anastomes. In those Dianemas, that I have met, the capillitium is lighter and seldom anastomes.

I still imagine to see a stalk and columnella in the 100x microphoto with brown capillitium radiating from the columnella.
There is the genus Diacheopsis, which is dark coloured and the shape reminds Dianema, but I prefer Lamproderma to the genus for this.

These turned very dark and I know no black Dianema, but there are many species in that genus, that I have not found. So, I may have totally misstepped,

Marja
