On Abies needles
Zuzana Sochorová (Egertová), 04-07-2013 23:29
Zuzana Sochorová (Egertová)Good evening,
in spring I found these small ascomycetes on Abies alba needles. The biggest ones measured about 1 mm in diameter. I though it could be Cistella acuum, but everything is too long in my fungus - spores are 5 - 8 x 1 - 1,5 µm, asci 40 - 44 x 3 - 4 µm, hairs up to 105 x 2,5 µm. The inner ring is blue in Melzer. The hairs are covered with granules.
The other possibility I considered was Dasyscyphella pulverulenta, but my fungi lack the yellow resin and the shape of spores is a little bit different in comparison with this picture: http://www.ascofrance.com/forum/15317/cistella-dasyscyphella?

Locality: Czech republic, Moravia, Dlouhá Loucka
Date: 13th April 2013

Would someone have a tip?
Thanks a lot, Zuzana

Re : On Abies needles
D. pulverulenta is on Pinus, and on Picea exists a paler, more whitish form (pulv. var. piceicola). It could well be one of these. Are the hairs actually so densely septate? 

Your drawings are a bit too schematic, from a photo I would perhaps be more sure. The hair apex should be smooth, not warted, however.  Otherwise Lachnum virgnineum would be an option.

Re : On Abies needles
Thank you. The hairs are really quite densely septated - I saw up to 11 septs in a hair. The whole hair is warted.
It´s not possible to make photos in my microscope :-( I tried to take a photo by a camera put on the eyepiece, but there´s nothing to see there (no details).
Probably Lachnum virgineum is the best idea.

Re : On Abies needles
The dense septation near the hair apex is very unusual in Lachnum, but typical of Brunnipila. Maybe it is only a divided plasma in the dead state, no true septa?

You have a camera with a much bigger lens than the eyepiece, I assume.

You have a camera with a much bigger lens than the eyepiece, I assume.? Yes, I do :-) I will try o get a more suitable camera then and make some photos of the microstructures.

Re : On Abies needles
Hello,
my way to make pictures through de bino, is an older type of the canon with display. They have the same lensopening as the oculair of the bino. I already do this for years. When the camera is broke down I look at bijv, Markplaats to buy an older example. The costs are low then.

Hi Zuzana,

be sure you have your camera set to infinity (very often a mountain symbol) not to macro or something else...

regards

Re : On Abies needles
But macro works also: I am doing my microphotos with the Coolpix always at the closest focus (2 cm), it makes a little more magnification, as I use the minimum zoom.

Important is to open the aperture and to have strong light to get a short shutter speed.
