Tiny star on Picea cone

I noticed this weird little star-shaped thing last fall on a fallen Picea abies cone. Something similar seems to be on the post that Alain just added (first pic).

When I tried to remove it with tweezers, it just popped like a blister. I'm not at all certain that this is a fungus, but it also doesn't remind me of anything else. Or could this be something plant or insect related?

Hi Juuso,

I am happy that this ''thing''appears here though it is not a fungus but I do hope that an Ascofrance member will give a name for it or the adress of some specialist to contact.

I did find it several times and never could get a clue for it ( something then of a ''cold case'' for me)

I join some pics , including after extraction of the ? animal.

Amitiés. Michel

Re : Tiny star on Picea cone

Thanks for the reply and great pics! The extraction pic is quite interesting -- it goes surprisingly deep. I thought it would be just a superficial disc.

Re : Tiny star on Picea cone

Our taxidermist here at TUR suggested that this could be (a remnant of) an egg of an arthropod. Heteroptera maybe.

Bonjour,

Je pense comme TINO qu'il pourrait s'agir d'un oeuf d'hétéroptère, ci joint une ponte de Réduve (Rhynocoris annulatus) avec son petit bouchon en "dentelle" (2 x 0,5 mm).

Michel peux tu m'envoyer tes photos en privé STP, j'essaierai de mettre un nom.

Amicalement,

Alain

Re : Tiny star on Picea cone

Merci Timo et Alain,

Peut être une bonne piste en effet même si les photos trouvées sur Internet de pontes de réduve semblent différentes.

On progresse ! Je t'envoie des photos Alain

AMitiés. Michel
