Observation 212320: Gibellula Cavara

8mm x 10mm on top of log near forest floor gathered August 2, white thread-like bundle, insect if present is completely obscured, but due to microscopy, suspect a small moth. It does not appear to be a spider.

very nice job of documenting anamorph micro! and a fun find for you; the insect, not so much.

oh yeah, this poor soul is quite dead. Death is apparently the stimulus to fruiting, even anamorphic fruiting.

creepy creepy creepy.

apropos of this sighting, I just read a pretty decent sci fi novel that discusses an apocalyptic scenario with human eating Cordyceps fungi! I rolled my eyes when I first saw that was their premise, but in fact they did a pretty good job with it, and the book was engaging and well written. I am pretty snotty about my novels, too, and this was quite good.

Here’s a link to a review on Slate:


one of many reasons why I think creating human munching mushrooms for those new age “death suits” is a terrible idea. ;)

when I first saw it I thought of woolly alder aphids

Phloxine is my recommendation. No redaction.

Are you redacting this comment? 1% Phloxine is the only thing I have at the moment, so I will be trying it either way.

Can anyone suggest a stain for this microscopy?

This is one of the simplest samples I have ever prepared – no cutting, just plop a synnemata on the slide, add liquid, presto.

I totally agree with you.

As soon as I wrote it, I realized the error of my brain.

Now I see it.

Not free, exactly, but free to try for 60 days, which is still pretty cool.

I beg to differ on the nature of your observation here. This is entirely anamorphic/asexual/“imperfect”, micrographs included. Conidia and conidiophores both clearly present, asci and ascospores both conspicuously absent. The projections you scoped correspond to the little white tufts lining the long white strands (synnemata). If I had my library with me, I could help rule in/out genera based on the characters present, host ID or none, but I’m currently traveling.

at your link – did you find what I am talking about? I even qualify! I also discovered that the key you recommended covers anamorphs; I was surprised to realize that this qualifies.

No! I did not. How did you discover this?

Thanks Danny for both links. I will give the key a try tonight. Did you know that a teacher can get a free review copy of the guide to Mycology in the Tropics?
