collected in the same area. I’m tempted to say that this one is C. cicindela based on the relatively ovid spores: Soop’s key splits small narrow-spored Brunneus-type Corts into C. carabus and C. cicindela based on spore shape – the one with ovoid spores is C. cicindela and the one with dacryoid spores is C. carabus, but in this case, this one’s spores are a bit too wide. It does look different – macro- and microscopically – from the second narrow-spored brown cort: observation 270176

I think the epithet referred to the "beetle-like size

of one of these smaller C. glandicolor clones (they’re maybe 1-2 cm in diameter), but I agree that it’s kind of too ascetic a vision…
Also,
I checked the spores of my September collections and it looks like I’ve outdone myself LBM-wise this time, because the slightly different groups we collected in a relatively small patch of forest near my home turned out to be C. coleoptera, C. carabus, AND C. cicindela (…and C. glandicolor and C. cf. ectypus and at least one other member of the sect. Brunnei, but all of those are much bigger). I’ll add some more photos a bit later.

By the species number argument…

God also has an inordinate fondness for corts.

I was hoping for something more… entomological. who looks at a species epithet ‘coleoptera’ and thinks “blackish brown and small” anyway? there are brilliantly colored, enormous coleopterans, are there not? boo!

thank you for the explanation all the same

I may be mixing up these two species

because only a couple of photos of each species exist in the Internet.
But both C. carabus and C. coleoptera (and C. cicindela for that matter) are little brown cousins of C. brunneus (sect. Brunnei). They’re all named so “entomologically” because they’re blackish brown and small :)

I actually think I’m mistaken with the id here: it’s either C. carabus or C. cicindela. I’ll re-check the spores.

interesting name

what are its origins?
