Soil Organisms; Dileptid

This is from a soil sample using a non-flooded culture technique. The organism is about 750 microns long. Long proboscis with oral apparatus at the base. Extrusomes along proboscis. Nucleus visible in all images. I'm guessing Dileptus as genus level ID based on what I can see of the nucleus. I found...

Re: Working with dirt; Clathrostoma

The soil samples were collected on a south facing slope in a pinyon/juniper forest, at an altitude of 7000ft/2133m. They included soil from the top 10cm or so and organic litter. Conditions were very dry. I filled petri dishes and slowly hydrated these until water would pool when titled about 45 deg...

Re: Working with dirt; Clathrostoma

Thanks for looking! I included an image below showing the area around the oral opening being mildly depressed but not nearly as obvious as Penard's drawing. Long fibrils radiating from the oral pit are not something I can find in any of the images I have. In fact, it took some work to capture the or...

Working with dirt; Clathrostoma

I've been working with dirt samples from around the house, using techniques described by Foissner. Many interesting ciliates I haven't seen before. This organism is about 100 microns in length. These images captured with Olympus 3.3x relay lens and SPlan 40x PL objective, live specimens. Kudo descri...

Re: Tardigrade

I collected the lichen then cut it in pieces a few millimeters in size and flooded it with water in a petri dish. I checked samples of the water 8 hours later (overnight) and found many tardigrades. This was my first try with this technique. I read about it at https://microcosmos.foldscope.com/?p=17...
