Last Saturday (September 21st) we were led by Julian on our annual Autumn Crocus walk in the Bradshaw area of Halifax. Here are a few photos from that day.
|The above image shows the yellow mycelial threads, that connect to the False Truffle.|

|This specimen shows the spore bearing surface clearly|
|Rooting Shank (Xerula radicata).
Note the wrinkled cap
It looks similar to the Pelargonium Webcap, but lacks the geranium leaf scent.
|Above the cortina can be seen covering the gills|
Peachy Steve and I have been emailing back and forth about this one.
We think it could be The Blood Red Webcap (Cortinarius sanguineus).
The second image clearly shows the radiating fibrils on the cap.
but I couldn’t resist posting some photos of my weekend away in Glen Loy.
One each from the pond dipping walk and the fern walk:
We had lots of fun dipping our nets and turning stones over in the water.
We look at tree branches without perhaps realising how they manage to support such massive weights.
It seems that Conifers and Broadleaves have evolved different solutions to the same problem but both of them use what is known as “reaction growth”.
Reaction Wood forms as a response to gravity and has different cell structure to normal wood, giving it extra strength, whilst laying down much wider rings which give extra bulk. The resultant cross section is often elliptical, particularly in conifers (as seen in photo below).
Broadleaved trees produce Tension Wood on the upper side of a branch, pulling the branch upwards.
Whereas Conifers produce Compression Wood on the underside of a branch, pushing the branch upwards.
Tension Wood has more cellulose and contains a specialised gelatinous layer in the cells, which is rubbery in texture.
Compression wood produces much more lignin and this altered, stronger growth has been utilised by hunters in the American Arctic to make bow staves from trees that were otherwise unsuitable.

The middle image shows the striate edges to the orange cap.
The third image shows the stipe covered in cap coloured squamules, and the cream coloured gills.
Although not rare, it is an impressive and beautiful fungi to find.
It has a very variable cap colour, ranging from violet, grey, green and purple,
which can be confusing when trying to identify it.
One key feature is that the gills don’t break easily when rubbed, unlike other Russulas.
