Elastic Oysterling?

Was back in Rowland Wood yesterday so thought I'd grab a specimen of that Oysterling I found growing on pine brash last month.

Here's where it was growing.

Here's what it looks like.

And here's my specimen.

The key to the Panellus species in Funga Nordica takes you to two species with whitish or buff fruit bodies: P. stipticus and P. mitis.

I've seen P. stipticus – the Bitter Oysterling – before, at Woods Mill (photos here). One of the features that Funga Nordica lists as separating the two is "gills abruptly delimited from the stem" in P. stipticus and "gills not abruptly delimited from the stem" in P. mitis. Well, I wouldn't say it jumps out at you exactly, but when you look at this photo I got of the underside of P. stipticus...

Panellus stipticus - for comparison. Specimen from Woods Mill, as described in this blog post.

... the gills do look like they terminate more abruptly at the stem – compared with my slightly blurry photograph of my current specimen, in the photograph above.

When you try peeling away the skin on the upper surface (the 'cuticle') of my specimen, it does this:

Stretchy, right? The stretchy layer is also quite sticky underneath. Funga Nordica lists "elastic" flesh, with a "gelatinous layer" as a particular feature of P. mitis.

I think it's looking good for this being Elastic Oysterling Panellus mitis. But can anyone confirm?

I was hoping to confirm it has white spores, but I laid out my specimen to get a print and it's just dried up without dropping any spores. Boo.

  1. I think you have made a very strong case for P. mitis Elastic Oyster Ling. To get spores from the dried specimen one can take a small piece of gill and rehydrate with dilute KOH. That is what the mycologists working with fungarium excicata do. When taking a spore print a moistneed tissue and cover helps. Nice informative blog as always.

  2. Posted yesterday but it is not showing. I think you have made a conclusive case for mitis on field characters. If you still need spores try rehydrating a smallpiece of gill in dilute KOH or just water then tease them out. That is what that do with fungarium excicata

  3. Thanks for your comments Ted, both showing up at this end so not sure what happened there. Cheers for the tip about obtaining spores from dried specimens. Do you know a good place where I can get hold of some KOH?
