Three for ID

[flaxton]

Glorious sunny day but still interesting finds out there.
first a very small grey, hairy "crepidotus"



I am going to have difficulty getting enough spores off a fruit-body that small to check the colour so any suggestions anyone

Second a dark Mycena
which I will investigate.

and finally a rather scurfy small specimen growing on a log with a slight pink tinge and then turn over and
Wow. Unfortunately I have still got no idea what it might be.

Thanks

Mal, I can give you a name for the last of your species the one with the pinkish gills and scurfy cap, this is Melanophyllum haematospermum as to the other two, the middle one looks like a small Pluteus the first is not at all familiar to me, maybe Nick can help here?

Thanks Andy

I thought I had looked at every page in B&K but obviously not.
The middle one which I thought might be a mycena (and now I am not so sure) is about 5mm across so a very small Pluteus,

Ah I've just spotted another emergent specimen to the lower left of the Pluteus! How very cute

5mm seems too small for a Pluteus I don't know of any that small. The colour and what seems to be some wrinkling in the cap had me thinking Pluteus.

Hi Mal,

Fungi are...............

'Crepidotoid' rather than Crepidotus ! This is Resupinatus applicatus (a young basidiome) - doesn't appear to be R. trichotus since the 'hairs' on the pileus are not black and bristly !

Yes, I think a small Pluteus but couldn't say which species from the photograph.

And yes, Melanospermum haematospermum (=M. echinatum as was) as Andy has suggested - couldn't be anything else with those red gills !

Ah Resupinatus applicatus I shall keep a look out for that. The 2nd does look like a Pluteus I thought so, small though hey? One of those rivulose capped species.

Hi Andy,

If you can get hold of the Spring issue of The Forayer 2007 there is a 2 page spread covering this species on pages 28 & 29 .

I must say Andy, for someone with your obvious experience, I'm very surprised you seem unfamiliar with this tiny species, it is easily overlooked, but I'm sure there isn't much which escapes your searching eye.

Neil.

Thats right Neil, I an only unfamiliar with it precisely because I don't see it in these parts and I have covered a fair bit of ground most of it repeatedly every year for the past decade or more.

I got confimation today from Michael Jordan for the "dark Mycena" or "Pluteus sp". It turns out to be Hydropus floccipes

One for the A-Z

Hydropus floccipes ??????????????? - without the absolutely (and always present) characteristic black dotted punctae on the stipe - really ?????????

I sent off the dried specimen so on this occasion as the expression goes up North - I'm sayin nowt

Mal, You should have sent it to Kew, far more reliable.

I think this is a classic example where a spore print from a fresh specimen would have helped enormously.

I have to confess that I couldn't even venture a guess at the identity from the photo. But what you can see from the photo is a specimen with a distinctly fibrillose cap. Aside from Nick's point about the stem, which is a significant issue, I would also be concerned about the texture of the cap.

Flora Agaricina Neerlandica 4 gives the following description for Hydropus floccipes:

"Basidiocarp mycenoid; pileus 5-25 mm, from conical or parabolical to applanate or slightly depressed with umbo, dark brown to grey-brown sometimes with olivaceous tinge, sometimes paler at margin and darker at centre, later pale grey-brown, with margin mostly non-striate but becoming striate in late stages, glabrous, minutely fibrillose under lens, sometimes somwhat rugulose;"

British Fungus Flora 8 says of the genus Hydropus that the caps are smooth, fibrillose under a lens. The cap of H. floccipes is said to be "radially silky atomate not striate, becoming minutely scaly in the centre".

I have to say that the photo appears to show a cap with a very different cuticle from that being described in either FAN4 or BFF8. The texture looks distinctly fibrillose to the naked eye... but how does this compare with "radially silky atomate".

In keying out the specimen, if I had arrived at Hydropus floccipes for the specimen in this photo, I think I'd be retracing my steps and checking thoroughly that I had not been led astray at some point.

But with a little-known species like this you just can't say very much of any substance based only on a photo. The person who had the specimen and looked at the evidence first-hand definitely has the upper hand in a case like this.
