... on naked red soil under Ceratonia, Olea and other mediterranean bushes, near Tor (Algarve). It does not seem to be an alga - the contents in the cells are too small to be plastids. The filaments are without septa and branching dichotomously. One of my thoughs is a possible Glomeromycota but am quite helpless. Who can help?Yours, Lothar

Perhaps a Trentepohlia (alga) species ?

Hello Alain,
thanks for your proposal. But - I do not think so, at least not T. aurea. The filaments look different and have septa and larger inclusions.
Yours, Lothar

yes, you'right. It was just one idea, an other way than fungi

Hallo Lothar
Could this be perhaps a xanthophycaeous alga, like a Vaucheria?
at least I have a feeling that it may grow also on naked soil and it is one of few "macroscopic algae" with discernable filaments
here is one link:
https://fmp.conncoll.edu/Silicasecchidisk/LucidKeys3.5/Keys_v3.5/Carolina35_Key/Media/Html/Vaucheria_Main.html
the sterile thalli do not necessarily have septa
all the best
