Have some things on my yard that I am not sure what it is. I have gone
to two garden shops and got two mutually exclusive responses.
After rains the last couple of weeks, I have a cottony cover on my
grass (I thought originally it was stuff from the cottonwood or some
weed sticking to the wet grass (see picture). However, soon I realized
that the grass in the area was turning brown in roughly the outline of
the cottony cover. One guy suggested fungicide and another just thought
I should fertilize and it would come back.

The first picture appears to illustrate a multi-cellular filament
organism, which would mean it is mold, a type of fungi.
Here is just one of many articles on the topic.
there's a few things that make clay tough to
have in a lawn, but you can often work around
when you core that area put down some extra
organic materials (compost is best) and rake it
a bit to get it into the holes before the clay
plugs break down and return there instead.
mow higher and don't remove the clippings.
don't mow the area when it is too wet as
that compacts the soil (especially for clays).
encourage or add worm species that will improve
drainage (but they do need the organic material
from mowing left behind). if your area is not
environmentally sensitive and you can bring in
night crawlers they will improve your drainage
but they need to be transplanted with a little
work. they don't start new burrows easily so
you have to dig up several areas and then put
them under several inches of soil so they have
a chance to start their burrows (when you see a
night crawler away from its burrow after it rains
that usually means it's in trouble). worms are
bacterial factories and help break down dead
organic materials (which helps reduce problems
as for fungicides and such, often a pointless
expense as the fungi spread easily on the wind
I just googled lawn fungus and looked at pictures:
Looks like that is what you have.
Might mention this company sells lot of stuff. I just bought from them,
good prices and free shipping:
interesting. clay is very fertile and good for
holding nutrients, after 29yrs of grass clippings
that area should have built up somewhat to excellent
soil. is there a slope there or some other way that
the organic matter is moving away? or is it a low
spot that collects extra water?
that is also likely the reason why the white
stuff has shown up anyways. i would just put it
all under "natural variation" and keep on mowing
now is a horrible time (mid summer) IMO. later
in the summer/early fall will be better (but i
don't know your location so i'm not really sure :) ).
for crawlers you have to give them a start, you
can't just dump 'em out and expect much. the other
earth worms and red wriggler aka compost worms they
are much smaller and don't need such an approach.
what worms did you try?
i hate to say it, but you could use it if you
really are that concerned. as in probably early
will help more rather than later. but like i say
i consider it a waste of time/money. then again
i'm just one of those strange people who doesn't
much mind fungi - they're a part of this life cycle
so when they show up they're doing something
important. we have a friend who actually goes out
into her lawn and picks the mushrooms thinking that
it will stop them. *SMH*

Best would be to try to identify it using the many lawn websites
and googling for pics of the various lawn fungi and indentifying
conditions. Then he can find the fungicide most suited, assuming
it's worth treating. I've never had success trying to treat it.
Seems by the time you notice it, try to figure out what it is,
the damage is done. And many are not lethal to the lawn, just
damage it. Some can and do kill. If there is an agricultural
extension service in the area, they can be helpful. They tend to
know what's a problem in the area at the current time.
the problem with almost any agricultural educational
institution is that they are firmly in the "sell poisons
and other sponsored stuff" camp.
few are serious about natural methods or simple and
inexpensive things that have been proven over centuries.
if it doesn't generate research $ from corporations or
government funding they aren't much interested in it.
so yeah, go ahead and ask, but they're likely to repond
similar to the OPs initial two suggested reponses (add
fertilizer or use *cides).
No on either one, at least so far the sloped areas are free. It is
flat ground and largely full sun. Also, the two places I have had the
problems are separated (one side of the pool in the back and around near
the driveway on the front with no communication between the two.
Central Indiana. I am not sure, I tried it a couple times about 10
years ago with the same results both times. I do get a bunch of worms in
my pool over the winter, so they seem to roaming around.
Interestingly enough (at least so far) I tried a bit of Miracle Grow
spray on I had handy as an expirement. It seems (again so far) that the
brown spots are less brown and don't seem to be spreading. It has only
been a day or two so we'll see how it progresses.

Here is a very interesting four page monograph, published by Perdue
university: "Using Organic Fungicides"
I have never used the organic approach to fungi, but after reading
this, I would be willing to give it a try.
