Crepidotus on pinus

[FungiJohn]

Hello all

Whilst at Sherwood Pines recently, Les found this Crepidotus on pinus which is proving to be a real problem identifying.

Here are a few images:









Note the ‘paler’ older fruit bodies in the last image

Samples will go to Kew when they reopen

Any help as always much appreciated

Hi John
With most of the Crepidotus I think it is best to work through the keys as they all tend to overlap macroscopically, although most of the species that can grow on wood seem to prefer hardwoods.

If it has punctate subglobose spores it may be C.applanatus, as this is fleshy and hygrophanous, and can occur on conifer wood. Best try BFF Vol 6 or/and Fungi Nordica.

Hello Peter

Thanks for that. I sent the images to Nick and he wrote back:

'It appears to be a genuine Crepidotus as well, since the edges of the lamellae are entire (not a Lentinus or such like, when the edges would be serrate-fimbriate). But the whole thing is the wrong colour !

My only guess (and it is a guess !) might be Crepidotus applanatus var. subglobiger which grows on pines and is easily distinguished by it's almost sub-globose spores BUT your material which appears to be in very good condition, just doesn't look right, colour-wise.'

I've not checked for clamps yet but tried keying out in F Nordica to come across problems of colour and the fact it is on pinus!

... microscope now warming up

Consider Panellus mitis => pinkish, Autumn to Winter, grows on dead wood from conifers.

Good call Leif, I had Panellus in mind too but not the species. However having seen the image on Mycokey I am tempted to concur. Let's hope John can get a positive ID.

Hello,

Leif is correct, no doubt that this is Panellus mitis. The gills are not the slightest brown and the fruitbodies are pleurotoid with a short stipe. In Crepidotus they are fixed without a stipe.

best regards,
Andreas

Hi Leif

Panellus (mitis) was my second thought but rejected through not having a distinctive, if short, stipe. However, the gill images clearly show this characteristic.

I'll look further tomorrow ... later today

Thanks too Andreas

Hello all

Kew have confirmed this to be Panellus mitis - typical amyloid, allantoid spores and gel edge to gills.

Many thanks to everyone for their input.
