Scored a nice one today. This one is really fluffy around the body as opposed to mostly poking out of the joints like I usually see. Pulled this one out of my basement. The spores under the microscope are very very small.

 

I plan to test it out in lc form on the gypsy moth caterpillars on my property. They are still really small and all huddled up together so it will be easy to hit them with lc.

That is pretty cool! (I had to google it)

"Beauveria bassiana is an entomopathogen that infects a huge variety of insects and is used to control crop infestations by aphids, thrips, and whitefly. The fungus is cultured in solid state fermentation and formulations of its conidia are sprayed on plants as an emulsion or a wettable powder."

It'll be interesting to see what you can do with it.

It looks alot like cordyceps. These are shots of freshly germinated spores (ascospores?). This is after about 30 hours on light pilsen agar.

So this stuff is really strange. It doesn't reach out into the agar or spread at all. All my t1's are just little puff balls in the center of the plate. Under the scope it hasn't reached out into the new agar from the wedge and it has been several days, maybe a week. I'll make up a buggy agar tomorrow with crickets in it and see how that goes. I have an acquaintance working with a culture and he says he just grabs random bugs and cooks them in his agar. A pic I saw of his had an assassin bug in it and the mycelium although fine was running through the agar. We'll see how crickets do.  The T1's under the scope look like they are forming spore producing cells.

It is very slowly crawling out into the agar now.

The little diamonds are enzymes I believe.

Thanks.

 

I wish the camera had better resolution. With the naked eye, the field of view is much bigger and the clarity is crystal.
