Talk:Biological soil crust

"crust microorganisms which are active only when wet"
The biological soil crust article says, "crust microorganisms which are active only when wet". In lichens, the thallus must be saturated with liquid water (i.e., wet) for cyanobionts (cyanobacteria microorganisms in a lichen) to photosynthesize, but phycobionts (alae microorganisms in a lichen) can have a net output of sugars with only water vapor. From the article on Peltigera - "Peltigera are often terricolous lichens (growing on soil)... and many Peltigera species are cyanolichens (having a cyanobacteria symbiont), but some Peltigera spp. have only an algae symbiont, (i.e., a phycobioint) and others have both." This seems inconsistent with the first quoted sentence, unless the sentence is intended to refer only to free-living microoranisms, not to those living in association with fungi in a lichen, in which case it should be sourced.

Section title: "Free-living Fungi" or "Fungi"?
Under "Natural History", there is a section called "Free-living Fungi". However, the first sentence of that section notes that it applies also to microfungi in symbiosis with algae. Shouldn't the title therefore be "Fungi" (or perhaps "Microfungi")? Knowing nothing about this topic, I'd thought I'd ask here first. --Larry/Traveling_Man (talk) 19:24, 17 August 2018 (UTC)
