CA Alligator Lizard ~ 03/10/14 ~ Midpen Preserve


We saw several alligator lizards this day.  Most of them were smaller with various patterning, but this one was huge.  Note the long tail that looks like it's never broken off, which it apparently does at the drop of a hat.  I've never seen this personally, but I trust what I've been told.  The cool temperatures, especially in the shade under the trees, left most of the reptiles we found kind of dozy and easy to approach.  Usually, I find it near impossible to catch a picture of an alligator lizard.

I should note, I base all my herp IDs on Gary Nafis' California Herps website.  Ya, I know, I complained bitterly when I first found it 5 years ago, because of the impossible-to-decipher-by-looks-alone way herps are classified.  It's not Gary's fault.  Bar none, he's created the best herp site for CA out there.  It's up-to-date, extremely thorough, and easy to use.  There seems to be an unusual amount of funding to do PCR-crap (oh, did I say that?) on herps.  It's like all the university herp folks are in a race to see who can reclassify the most spp.  I'm sure there's historical biology precedent as to why this is, but I just find it perplexing.

OK, what are they feeding the amphibians at this preserve?  Good golly, they're fat and huge, just like the Pacific chorus frog we found.   Seriously, no one is actively feeding these wild-found animals, but there must be plenty of food stuff available and plenty of comfortable habitat.  In one month's time, the CA newts have gone from skin and bones, like at nearby Stevens Creek on February 10, 2014, to fat, fat, fat.  Ya, the two locations have very different habitats, but still!  I'm unsure if the one in my hand is male or female.  Are those male nuptial pads on the toes?  Do you know?

Oh.  My.  God.  Look at how fat and huge this adult is!  Fatty, fatty frog.  With its dark throat, I'm guessing it's a male.  Those toe pads are amazing.  Oh, that large hand is not my own. Compare the size of this sucker with this anemic-looking juvie I raised a couple years ago.  

Apparently, I prefer an outdated common name by calling it a Pacific chorus frog on Nature ID.  I don't get why "treefrog" is commonly used as one word, when in fact, it is a frog.  Remember, I used to be a science content editor.  Technically (there are indeed naming rules for common names), if the thing in question is truly the noun, then it is at least two words, descriptor 'space' noun.  If the thing in question is not the noun, then it is either one word (e.g., butterfly is not a fly) or hyphenated (e.g., poison-oak is not an oak).  Perhaps, like its/it's and their/they're, this is a frequent grammatical error that many people don't pay mind.  At what point does common usage change the rules?

wolf's milk and common grey disco ~ 03/10/14 ~ Midpen Preserve


It amazes me how so many natural sightings are time sensitive.  Just the week before, Ken mentioned a distinctive slime mold (which is not a fungus btw) called wolf's milk.  Then, Cindy also included some nice pictures in a recent blog post.  Fun name, no?  So, when I found these, I knew exactly what they were.  I've only ever seen the creeping plasmodium of other slime molds before, not the aethalia (aka sporangia stage) like these pink balls are.  I squeezed a couple, and sure enough, pink milk squirted out, reminding me of Pepto-Bismol.  Oft-repeated descriptions of the milk being a thicker consistency of toothpaste was not my experience. These aethalia were probably too young to be thick.  They're like pea-sized pink paintball pellets (apologies for the excessive alliteration). Apparently, our wolf's milk don't know they're only supposed to be out June-November, yet another oft-repeated statement that doesn't match my encounter.


It wasn't until I got home and looked at my pictures of the wolf's milk that I noticed the tiny grey disc clusters.  I probably should start carrying my reading glasses wherever I go (ugh, one more thing to haul around).  I thought I'd never get an ID on them, but a couple days later during my blog reading, I found Skev's B.L.O.G. had posted Mollisia cinerea from across the pond.  Oooh, a lead.  I'm not sure if what we have in CA is the same found in the UK, especially considering there are several grey-colored Mollisia spp. 

As a side note, there are other similarly looking cup and saucer fungi, but colored sunny yellow, called lemon disco (Bisporella citrina and its smaller sibling B. sulfurina).  It's the tiny world of cool.  Shall I dance?
