Orbilia elegans anamorph?
Chris Yeates, 29-10-2021 20:54

Bonsoir tous

As part of my study of the fungi occurring on the dung of mountain hare Lepidus timidus I have come across Arthrobotrys conidia: 45.6-48.1 x 20.7-22.5µm. These seem to fit best with the anamorph of Orbilia elegans. Comments very welcome.

Amitiés, Chris

Re : Orbilia elegans anamorph?
Hi Chris

possible indeed. But such conidia exist in different groups. I am not sure if we can exclude a Dactylellina or a Drechslerella anamorph.

If you succeed to find trapping organs, it would be better. But to be sure they belong to the condidia will be difficult.

Within series Arthrobotrys it could perhaps also be thaumasius or eudermatus (in the monograph you can search for them like this: "#thaum" or #euderm", but there is no morphology. A. thaumasius was confused with A. eudermatus and that with A. elegans (by morphology). DNA from the types show this confusion and that they are three different species.

For Arthrobotrys we did not do a survey of drawings from the literature because there are so many species.

Re : Orbilia elegans anamorph?
Thanks Zotto

Yes I did work my way through the relevant sections of the monograph and can see the potential for confusion. I was taking the occurrence on lagomorph dung as perhaps more significant than I should have?

Re : Orbilia elegans anamorph?
There is perhaps no species of Orbilia confined to dung. Especially those nematode-trappers tend to grow there, but only sporadically.
