Observation 63489: Galerina hypnorum (Schrank) Kühner

When: 2010-10-06

Collection location: Berliner Stadtforst, Berlin, Germany [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found on moss, on a rotting log, under pine, birch, oak.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are lageniform to cylindrical, with blunt to somewhat swollen ends. No pleurocystidia were obs. Also 4-spores basidia, with dextrinoid spores.

The second micro-shot is of the cap surface at 400x in Meltzer’s. The cap surface is a cutis with no gelatin or pileocystidia.

The third micro-shot is of the stipe surface at the apex at 400x in KOH. The caulocystidia are cylindrical and some bent.

The forth micro-shot is of a spore from the stipe at 1000x in KOH. The spores are ellipsoid, pointed, slightly roughened, but mostly smooth, only a few calyptrate, with a loosened perispore at the apiculus.

The fifth micro-shot is of more spores from the stipe apex at 1000x in KOH, mostly to give more feeling for the spore variation. The ave. spore size is apr. 9.5 × 5.5. um.

This also mostly points to G. hypnorum, except this is a slightly problematic taxon, with variations in descriptions throughout the literature. This matches well most of the European descriptions of this taxon.

Oh, you mean the posed shots.

You mean, just what is used for the shots with white background. Actually those are just white paper, nothing else. It is kinda method I developed to be able to take a similar shot, separated from anything else, anywhere, and easily even when traveling. So, just white paper, and make sure it is white, not light yellow. Then find a place with even illumination, of the same color light. And set white balance off the white paper. Then also use the white background to calibrate the light levels in post-processing. So, then hopefully the posed shots will look the same, or similar enough even when taken in different places, and conditions.

It works ok, most of the time. I guess the studio is the same everywhere, since it is just white paper. The light used is different for each place.

I’m referring to whatever it is you use for your studio shots. I’m envisioning a little collapsible white box with lights mounted inside. Or is it just up against white paper each time? I’m a color balance nut, hence the question.

Sorry, not sure what you mean.

Don’t know what you mean here, I take the same what everywhere? The same mushrooms everywhere?

what’s your studio setup like? do you take the same one everywhere?
