Topic: Kiron 105 & Schneider HM40: A Yellow Toothed Rarity?

I was searching through some Sycamore logs, cut about two years ago, and stored, stacked, in our garden. I was looking for slime moulds to photograph when I came across this crust fungus. I looked photogenic, not least because it was rather three-dimensional. Anyway, I took some shots, some with my Kiron 105mm at f16 and some with my reversed Schneider HM 40 setup, also at f16. The latter were at about x6 (FOV 6mm wide).

There is a low magnification crosseye stereo pair.

I sent some of these image to Paul Hugill, one of the authors of the 2015 book "A Field Guide to the Resupinates of Hampshire" by Paul Hugill & Alan Lucas. (Resupinates is the scientific term for crust fungi). Paul has said it looks like (my underlining) Mucronella flava. "Looks like" is not the same as "is", due to the difficulty is working only with photographs and not with a specimen. (My comments).

In the book, this species is said to be very rare (in Hampshire).

EM-1, twin TTL flash, hand-held.

Mucronella flava: More Images

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.
