Baited fungus, help with ID.

Collected from loamy soil, at waterside (completely wet soil thus )and baited on aquarellpaper,I detected a very small set of fungi, one anamorph, as depicted, and a perithecial fruitingbody assumely the teleomorph.

The other photograph  depicts conidia, or ascospores from te ascomycete.The perithecia were to scanty and, mostly, to small ot prepare from the paper.The anamorph is captured under cellotape.

I do not have a clou where to search for the fungus/ fungi (I do not give mesurement at this point )if, a.i photograped conidia, b. I made a photograph of some, to me, strange spores.

Maybe someone has an idea ?(Giving pictures of the conidiogeous cell would be premature now, I think. )

Re : Baited fungus, help with ID.
Considering the cellulose-baiting from wet soil, some of the fungi involved are likely cellulolytic.

The brown spores show a general resemblance to Chaetomium-like ascospores, but this should be treated with caution in the absence of asci or perithecia.

The conidiomatous structure could be Botryotrichum-like, a genus often associated with Chaetomium.

With the data currently available, this remains speculative and is only intended as a possible line of thought, should you wish to explore it further.

Best regards

Re : Baited fungus, any idea ?
Baiting with that paper is for collecting cellolytic fungi.So no suprise.

 The idea about th anamorph  is a nice one worth to dive in the literature for.

It is by no means  a Chaetomium however from which are the black spores.The perithecia I mentioned lacked hairs or setae.Chaetomium has, as far I am aware, no spores with appendages, as seen on my photo.It is like a collarette, and realizing that, i remember seen pictures , or life material, of such spores. In the Sordariales ?
