My previous topic on this species left some doubt as to which of two species of Mucronella it might be. I was waiting for local experts to settle the matter by collecting some of the colony. Then I consulted the Book "The Microscopy Companion to the Resupinates of Hampshire". From that, I learned that the tiny structural details of the two species were mostly identical. However, the teeth of M. calva were up to 0.5mm long and those of M. flava up to 2mm long. Having a 4x3 format, and at a FOV 6mm wide, it only took a look to see that the 2mm was often attained and most spines were at least 1mm. It was M. flava. QED!

Here are some more images, mostly taken yesterday but including some of the original ones, this time showing some curved spines. The crosseye stereo is from another colony in the same pile of logs.

EM-1, Kiron 105 or reversed Schneider HM40 plus Kiron x15 TC, both at f16, twin TTL flash.
