That’s an excellent point about wanting to provide specific info regarding anything that may be mistakenly IDed as fungal.

Insecta vs. Arachnida

This is caused by a true bug (Hemiptera), which is in Insecta, Arachnida has spiders, scorpians, mites, ticks, etc. which are not insects. This link can help explain some methods of telling them apart, but is specific to spiders. http://www.burkemuseum.org/spidermyth/myths/notinsects.html

And I believe anything that could be mistaken as fungal deserves a place in MO, so applying the actual name that we now know should be appropriate I think.

Penn State University. Determination… Adelges tsugae, the Wooly Adelgid, which is an insect. I don’t know enough about insect classification to know if this falls into the category “Arachnida.”

I’ll pass on officially proposing the species name, since this would require creating a new name that does not represent anything associated with the Kingdom of Fungi.

… hyphae? I don’t know.

Smash mount of white stuff on hemlock twig.

That seems like a very plausible possibility, Byrain.

Actually, I had no idea about this. A colleague of mine (a person from the Bio Dept) left it inside my office mail pouch for me to examine. I have not yet had a chance to speak with him.

Thanks for the suggestion.

be something like hatched spider egg sacs? They look webby and I think I see some exit holes.
