Hi everyone, I found this white, star-shaped
Lachnellula subtilissima, but not quite!?

Recently found a gergarious group of what appears to be a Lachnellula species on probably a fallen Pinus branch. All looks reasonable for L. subtilissima except some paraphyses have 'spear-headed' tips or spathulate-lanceolate ends. Some are rounded cylindrical as perhaps expected. The other question relates to the hairs where some seem to have crystals forming at their tips. Some rounded some blunt ended. Marginal hairs white at first soon changing to yellow. Any help would be very much apprecaited.

Re : Lachnellula subtilissima, but not quite!?
The colour sounds strange although your last pic looks typical. I see one paraphysis with orange droplets. Alternatively I considered L. pulverulenta (in my files still in Dasyscyphella), but there the asci must be with croziers and no orange hymenium occurs. Besides, the substrate is inus needles.

Hello!
Why not use a dye like Congo Red SDS for something like this?
I'm sure your find is croziers+.
Greetings

Re : Lachnellula subtilissima, but not quite!?
With thanks Otto and Ingo for your comments. Lachnum pulverulentum had been my first choice but let this go due to macro colour differences especially on the hymenium. However, I hopefully have corrected my mistake that Ingo suggested and that Croziers exist as shown here. I have added other pics of the paraphyses as I couldn't find any other orange droplets. There was also no orange resin collected on the hairs tips when drying. The paraphyses slight lanceolated tips suggest more a Lachnum sps perhaps? The hairs were seen to contain 4-5 curved septa.
with thanks again, perhaps this shouild be Lachnum pulverulentum?

Re : Lachnellula subtilissima, but not quite!?
No, this looks clearly without croziers to me, which rules out pulverulentum.

Re : Lachnellula subtilissima, but not quite!?
Thanks Otto, confirms my original thoughts but was never great on croziers. All points to my original suggestion of L. subtilissima as I can't see anything else that gets this close.
Thanks again for your input.

Re : Lachnellula subtilissima, but not quite!?
Yes, now it is better and I believe croziers-.

Hi Tony,
You can probably improve color artifacts by choosing a 6000 - 6500° Kelvin light source. LEDs are often poorly suited to reproduce natural colors. Natural daylight without direct sunlight is likely to make this Lachnellula's hairs appear less yellow. One tip is to include a narrow strip of really white paper in each macro photo.
Kind regards,
Guy

Hi Guy, thks for your comments. I'm sure you are right, but in this instance I took the macro in the field in low natural light (no sunlight) and was looking for the whiteness of the hairs which showed here. If anything it is the light source at the camera on the scope that over compensated and the margin should look paler yellow. A direct natural light source would be better at this stage perhaps. regards

Hi Tony,
If I was aware that discoloration could occur after collection, I usually photographed the white strip of paper (placed in a corner) so that a subsequent white balance was possible when editing the image. It's crazy that after the invention of white power LEDs, there are almost no lights that emit the full spectrum (i.e. the equivalent of sunlight) anymore. The old halogen lamps had a very good spectrum, but are now rarely used for macro photography of small mushrooms because the IR content is very high, which means that small mushrooms dry out quickly.
That's enough off-topic for now.
Regards,
Guy
