out of topic - unclear layer on the ground in Portugal
Lothar Krieglsteiner, 12-02-2023 11:06
Lothar Krieglsteiner... 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

Re : out of topic - unclear layer on the ground in Portugal
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
