Lichens (a) Lichens are a polyphyletic grouping of fungi that possess algae (eukaryotic or blue-green) symbionts
(b) "The fungus usually gives the lichen its overall shape and structure, and tissues formed by hyphae account for most of the lichen's mass. The alga always provides the fungus with food. Cyanobacteria in lichens fix nitrogen and provide organic nitrogen. The fungus provides the alga with a suitable physical environment for growth. Lichens absorb most of the minerals they need either from air or in the form of dust. Fungal pigment shades the algae from intense sunlight. Some fungal compounds are toxic and prevent lichens from being eaten by consumers."
(c) "Lichens are important pioneers on newly cleared rock and soil surfaces, such as burned forests and volcanic flows. Physical penetration of the outer crystals of rocks and chemical attack of rock by lichen acids help break down the rock and establish soil-trapping lichens. This process makes it possible for a succession of plants to grow. Nitrogen-fixing lichens also add organic nitrogen to some ecosystems."
(d) See Figure 31.16, Lichens

the chytid fungus that is bringing extinction to some amphibians is an aquatic fungus
Salamander skin bacteria fight chytrid fungus Posted by ajcann on December 8, 2007
Beneficial bacteria that live on salamander skins have the ability to inhibit pathogenic fungi. Our study aimed to identify the specific chemical agents of this process and asked if any of the antifungal compounds known to operate in analogous plant-bacteria-fungi systems were present. Crude extracts of bacteria isolated from salamander skin were analyzed. These investigations show that 2,4-diacetylphloroglucinol is produced by the bacteria isolate Lysobacter gummosus, which was found on the red-backed salamander, Plethodon cinereus. Furthermore, exposure of the amphibian fungal pathogen, Batrachochytrium dendrobatidis, to different concentrations of 2,4-diacetylphloroglucinol resulted in an IC50 value comparable to crude extract concentrations. This study is the first to show that an epibiotic bacterium on an amphibian species produces a chemical that inhibits pathogenic fungi.

Good Findings here!!! There is something to this LICHEN
When I worked in an OB GYN clinic, many MIddle aged and older women were coming in with "strange" skin in this area and were diagnosed with LICHEN.
It was the FIRST time I ever heard this word LONG BEFORE I acquired morgellons. Yes I remember the good old days when I could feel "NORMAL".
Makes me very depressed today thinking about it.
Also remember the MD's would have the Pharmacy compound a Special cream for them.
Gosh, I don't remember what it was.
Before my mother died, I heard she was diagnosed with LICHEN.
I do wonder now what that was.

When I got my first rash from a mosquitoe bite, after being misdiagnosed with scabies, a skin specialist thought I had "lichen planus" because my rash glowed under a black light. It turns out he was wrong, it was Morgellons but I would not be at all surprised to find out that Morgellons is "Lichen" something...

'Lichen simplex chronicus on the ankle: Lichen simplex chronicus is also known as neurodermatitis.'
i had a biopsy done. the dx. was neurodermatitis.
i wonder how many doctors know that neurodermatitis is lichen? it was not mentioned to me.
when i look at the lichen symbionts.................. i see morgellons. i see the anatomy and it matches the particles that exit my skin.
i think the callus is actually the thallus.

i keep thinking about the hpv infection i got from a drummer in kentucky 30 years ago. i've had morgellons for 12 years. Human papillomavirus association with p16INK4A expression in penile lichen sclerosus and cancer Human papillomavirus (HPV) infections are sexually transmitted human carcinogens recognized to cause cervical cancer, that may play a role in the oncogenesis of penile cancer. This study shows a high prevalence of high-risk HPV infections in penile lichen sclerosus and cancer. HPV infection was associated with p16INK4A expression, consistent with an active role for HPV in interfering with the Rb pathway. High-risk HPV infection could be involved in the tumorigenic process in 50% of penile cancers, and the use of prophylactic HPV vaccines has the potential to prevent these cancers. Br J Dermatol 2008; 158: 261–5.

DEAD SEA research.haifa.ac.il/~evolut/Fungi/docs/GenInfo.html ) Micromycetes diversity in the hypersaline Dead Sea (DS) water. No reports existed in the literature on the occurrence of fungi in the DS until our research group has discovered filamentous microfungi in DS water ( Proc. Royal Soc. London, 1998, 265: 1461-1465). The survey of the DS mycobiota found remarkable microfungal diversity, namely 58 species, representing 24 genera of Oomycota, Zygomycota, Ascomycota, and Mitosporic fungi (in: Evolutionary theory and processes: modern perspectives. Papers in honor of Eviatar Nevo. (S. P. Wasser, ed.). Kluwer Academic Publishers, Dordrecht, pp. 293-300.). We performed several research projects with spatiotemporal diversity of DS mycobiota, survival of spores in hypersaline water, influence of salinity and temperature on their morphology, colonial growth and physiology. Now we direct our research towards studying of possible source of DS mycobiota formation, further study of spore germination and mycelium vitality under prolonged hypersaline stress. Most important, we would like to reveal whether mycromicetes in the DS water are present only in dormant spore stage or as vegetative mycelium as well.

www.bioremediate.com/index.htmi wonder if we could put this stuff in our hot water heater? i put bandaids over my lesions and look under the scope at what grows off it. i have been putting out the blue/green colonies and the lime green algae this week. it hurts! and smells!

check out my avatar to this pic This photo looks exactly like what keeps happening on my lips. One area heals as another breaks out. Sort of like a big blister with a yellow waxy fake skin that peels off revealing the blister....

ruth I had the same kind of lesion with yellow fake skin/membrane on the inside of my mouth. I was appalled when I showed my doctor this dime sized lesion with yellow waxy scab and she said it looked like the diaper rash of her baby. Do you think it maybe algae related?
