Hello,

Found by Laurens van der Linde on a young fallen tree, The Netherlands (04-11-2019)

Conidia septate: 8.6-9.0 x 3.5-4.0 µm

Who can tell us more about this species?

Re : anamorph on tree => Isaria friesii? Update 17-11-2019: + teleomorph
Oh this is superb! Exactly as we know the teleomorph from other samples. With its capitate paraphyses one might think that it might be described as an Orbilia in older times.

The substrate is unclear? Did you try to identify from the wood anaotmy or else? And I suppose the branch was exposed, not on the ground, as you say "young fallen tree".

Re : anamorph on tree => Isaria friesii? Update 17-11-2019: + teleomorph
I will ask Laurens if he can tell us more about the tree.

Re : anamorph on tree => Isaria friesii? Update 17-11-2019: + teleomorph
Laurens:

in 2018 on Urtica (old stem) and on wood (hardwood)

in 2019 on old tree (Populus) lying on the ground and on a branch of a collection of unknown branches (thickness 5 cm) 30-50 cm above the ground.

Only hardwood present: Alnus, Acer, Quercus and Populus.

Wood anatomy, a try .....

Re : anamorph on tree => Isaria friesii? Update 17-11-2019: + teleomorph
Ah, this is goods. It excludes a lot, with certaintyl Alnus and Populus. Important is now to look at a cross-cut, is the wood ringpored with large pores? Then it should be Quercus. But I assume it is Acer. This belongs to the 2019 sample?

Re : anamorph on tree => Isaria friesii? Update 17-11-2019: + teleomorph
Yes, this is the sample 04-11-2019.
I will try to make a cross-cut.

A cross section of the sample 04-11-2019.

Unfortunately the pieces of wood were so soft and brittle, they broke into small pieces and I'm out of material now ....
