Cumulus Clouds with Spikes

Summary Author: Mila Zinkova; Jim Foster

Shown above are curious shaped, cumulus clouds that were observed
from near my home in San Francisco, California, on April 19, 2022. The
spike-like features have horseshoe shapes in some cases, as shown in
the bottom photo. Perhaps these spikes and horseshoes are caused by
convection -- intense localized heating of the most optically
thick portion of cloud by the strong April sun. However, because the
atmospheric environment where the clouds formed wasn't suitable
( stable atmosphere) for widespread building, they remained overall
fairly “flat” in appearance. Click here to see a video of these
clouds.

THANKS FOR VISITING EPOD. THE BLOG SERVICE IS HAVING A TECHNICAL ISSUE.
WE HOPE TO RESOLVE THIS WITH OUR SERVICE PROVIDER SOON.

Summary Author: Matthew Chin; Jim Foster
Can you spot the sliver of the crescent Moon? Because it was only about
1.3% illuminated when this photo was snapped, at dawn on June 28, 2022,
it isn’t exactly conspicuous against the pumpkin-colored sky. As night
has now lost its grip, hordes of bats are returning to their caves
(could this be the source of the dark smudge at lower right?) and other
spooky, nocturnal creatures will soon be asleep in their lairs. Photo
taken in Yuen Long, Hong Kong, on June 28, 2022, at 05:12 a.m. local
time.

Basket Stinkhorn

September 30, 2022

Stinghorn

Photographer: Mila Zinkova
Summary Author: Mila Zinkova

Shown above is the Basket Stinkhorn, Clathrus ruber, that I came
upon during a walk in the woods not far from San Francisco, California.
Its odor is repugnant to you and I but is evidently like catnip to
flies. " They flock to her foetid scent, feed upon the
spore-impregnated greenish-black gleba, and soar off, spreading
stinkhorn spores in their wake."

Most often found in temperate deciduous forests, Clathrus ruber
hatches from an egg-like film. At the base of which is a mycelial
“root,” that at this stage has little scent and might be edible to
some. However, it doesn’t take long before its stench is so
overpowering that only a creature like a fly could be attracted to it.
Click here to see a video from hatching to decaying.
