? Cyanobacterial strands with terminal spore formation?

Post by jc maccagno »

Freshwater pond 40X, 100X

I cannot find any references to terminal spore formation in the Cyanobacteria. Can someone confirm that the organisms are cyanobacteria? Any references to spore sacs in this group would be appreciated Many thanks John

John,
to me it looks more like a parasite of the class Phycomycetes, possibly of the huge genus Rhizophydium (?).

You have found another very interesting microbe, or one in a different phase. I am looking forward to finding out what it is all about. :)

The two objects attached to the end of the blue-green filament is definitely not like any structure or spore type of the Cyanophyceae. I also think it could be fungal, possibly a sporangium of a chytrid. I have never seen anything parasitizing a filamentous blue-green except for a virus known to attack some genera.
