Parasitic fungus on insect larva and mite

Hello there,
today i found under a rotten wood this fungus.
This fungus grow on insect larva and on the larva are some mites, they have the infection too.
I know that a determination is difficult, but perhaps anyone know what that is.

best regards,
Thorben

EDIT:
First Fungus

Re : Parasitic fungus on insect larva and mite

Unfortumnately you did not show any conidiogenous cell and without that an identification is not possible. Globose conidia are not so frequent in these fungi and might stem from a Beauveria.

Schöne Grüße Walter

Re : Parasitic fungus on insect larva and mite

Hello Walter,
thats pity :(
I have find a other fungus near (2cm) that fungus.
The other fungus has the same Globose spore and some conidiogenus cells.
But i'm not sure if this is the same fungus.
Later i upload the photos.

Viele Grüße
Thorben

Re : Parasitic fungus on insect larva and mite

if it helps, this is beauveria growing on a larvae of Rynchophorus ferrugineus

Re : Parasitic fungus on insect larva and mite

Hi there,
here are the picture from the other fungus.

Hello Pintos,
thank you very much :)

best regards,
Thorben

EDIT:
Second fungus

Walter Gams, 20-03-2016 17:49

Re : Parasitic fungus on insect larva and mite

The second one is certainly not a Beauveria. It has verticillium-like conidiophores. I guess it is a species of Pochonia, but without a pure culture I cannot get firther.

Greetings Walter

Re : Parasitic fungus on insect larva and mite

Na dann, passt es doch gut.
Die Sendung ist draußen und kommt vielleicht noch diese Woche bei dir an.

Viele Grüße

Re : Parasitic fungus on insect larva and mite

I'm very happy :)
Today i found again the same insect larva (i mean its a caterpillar) on the same location.
But this one have two different types of spores.
Wether that now the same species as the first fungus are, that i don't know.

best regards,
Thorben

Re : Parasitic fungus on insect larva and mite

Darauf kann man wirklich etliche triviale Dinge finden. Lecanicillium, Beauveria etc. Walter

Thorben Hülsewig, 22-03-2016 20:05

Re : Parasitic fungus on insect larva and mite

Bisher kenne ich nur Beauveria bassiana und Isaria farinosa, die Lecanicillium steht dann ab jetzt auf der Wunschliste. Mal schauen vielleicht lässt sich diese morgen oder übermorgen noch entdecken :)
Ich denke ich habe jetzt die Strukturen zu dem ersten genannten Pilz auf einer 2.Probe von heute gefunden.
Kann man sich damit eventuell auf einer Gattung festlegen ?

Viele Grüße
Thorben

Konidienketten und flaschenförmige Phialiden wweisen auf Isaria.
