Hypholoma info please

[watsthat]

These were found last September,presumably growing on buried wood.
I`m not sure if they are, the very common, H. fasciculare or not. Are there any diagnostic features that I have missed, which might point to something other than H. fasciculare? The stem looks very pale, no sign of a ring zone and the specimens are not in the usual dense cluster of H. fasciculare.

I think they are confirmed by microscopy with most of the times the hypholoma being fasciculare.

An easy to identify hypholoma is H. marginatum which has the snake like skin to the stem.


As far as I know - the rest are confirmed with microscopy but some can be distinguished by habitat e.g. conifer tuft

This was my reply in another thread on the same subject:

"Back on the subject of the various species of Hypholoma, I am convinced that there are times when we dismiss that 'easily recognizable' clump as just another find of the uniform coloured, ubiquitous Sulphur Tuft - Hypholoma fasciculare, when closer inspection, especially throughout August - December, may reveal either Conifer Tuft - Hypholoma capnoides or Brick Tuft - Hypholoma lateritium. Both have slightly more reddish caps and relative distinct habitats of conifer stumps for H. capnoides, and deciduous logs and stumps for H. lateritium. Also the former has bluish grey gills darkening to purplish brown, whereas the latter's are yellow then greyish to reddish brown; compared to those of the much more common Sulphur Tuft, growing on both coniferous and deciduous trees, which has young greenish gills which become dark purplish brown with maturity. The similarly coloured stems of Conifer Tuft are silky smooth, but those of the other two may show traces of a darker ring zone towards the top."

So the gills on your find could suggest H. capnoides if other criteria fit the bill.

Hallo,

the growth on burried wood in a meadow would strongly suggest Hypholoma fasiculare, but the gill colour and the colour of the stipe apex show, that it is Hypholoma capnoides. So the burried wood must be from conifers, because H. capnoides is confined to conifer wood only. The other two are on all kind of wood.
The cap colour of capnoides and fasciculare often is exactly identical, so it is not to say from above which one is which. Only H. sublateritium is distinctly more reddish and also has much more veil, which is yellowish and often lies in patchers on the cap margin.

I have never noticed significant microscopic differences between capnoides and fasiculare by the way, and I'm not sure whether I could determine them from exsiccata.

best regards,
Andreas

A big thankyou to everyone for more fascinating insights. Its so helpful to hear other views and experiences. By the way the specimens were found at Castle Howard Arboretum and I know Flaxton (Mal) is familiar with the site. I wonder if he has ever recorded H. capnoides there .......... Mal?

Cheers

Hi Pete

No never found capnoides at the Arboretum but although I go there a lot it doesn't mean that you might not be right. It is certainly one for me to look out for this year.

Ps we must get together sometime in the coming season.
