Coleophora species on Hawthorn

 

I have been able to find a few larval cases on Hawthorn, mainly Crataegus monogyna or the hybrid I think. The ones I found look similar to each other and are I am afraid unidentifiable down to species, but they are still fascinating to see, so here is a picture that I was quite pleased with, not the one taken with the phone!

 

A few fungi from The Scambles

 

Interesting mushroom on well decaying fallen leg

Fuscoporia species on Hazel

Schizopora paradoxa rather broken down extensive coverage of log

 

Really quite weird apparent attack on the fruiting surface of Schizopora paradoxa, maybe leaving droppings?  

Stereum subtomentosum I reckon.

Surface of unknown crust. Could it be Schizopora again?

Not a bad half an hour?

Woodwarts on Hazel

 

I found some dead stems in a Hazel stool by the side of the muddy steep slope on the main path round the woods. On this one were some Woodwart looking fungi, apparently quite old and solidified, all along the stem. Judging by the colour and shape I would still say that this was fairly like Hazel Woodwart, Hypoxylon fuscum. I was unable to get any samples for KOH testing. 

 

I think there might be a separate tar crust under the peeling bark. Might be worth peeling back a bit more bark to see if there are any fresh surfaces to examine.

This next one looks different though, blacker and also erupting out of the thin bark. This was found near the Scambles, but fairly near the grass triangle end. Its just got a very different "jizz" to it.

   

Phyllonorycter coryli and nicellii on Hazel

Now, at the start of July, there are quite a few of the first generation Phyllonorycter coryli (Nicelli) leaf mines in their early flat silvery stage are appearing on the upper side of the Hazel leaves. Sometimes there are multiple mines per leaf. The caterpillars seem quite small, a couple of mm long at this stage. It would probably be better to wait a couple of weeks to see if we can find some pupal cocoons in order to breed through. There may be some up-folding of the leaves already, and that somewhat darker more contracted stage of the mine surface is the one to wait for. These should fairly quickly metamorphose into the adult moths. Sadly I had no luck getting any adult moths out of these mines.

The caterpillars mine July and September-October, while the two generations of adult moths are May and August. By implication there should be a resting pupal stage from October through April. Presumably this is in the decaying leaves and then the litter on the forest floor. There should also be a brief pupal stage between July and August that is our target stage for collection. The pupae should be in cocoons in the opposite corner of the mines to the piles of frass.

There is also the significant possibility of accidentally collecting numbers of parasitoids instead of unparasitised pupae. It will be interesting to keep an eye out for Braconid and Ichneumonid wasps.

and a closer view:

and I did find just one possible example of Phyllonorycter nicellii (Stainton), the Red Hazel Midget, which mines the underside of the leaf. I think I was lucky to spot it, as I just saw the darkness of the leaf fold. I didn't think that it was necessarily typical, but it did clearly have the "nibbling" around the edge of the mine clearly visible on the upper surface of the leaf, so I doubt it was N. coryli. The species appears to have a similar life cycle timing to Phyllonorycter coryli, and I found a few more over the following weeks, but this is still very much the minority species in this particular wood.

The NBN atlas claims that "the mine [of Phyllonorycter nicelli] is usually between two side veins. The pupa is formed in a white cocoon in a corner of the mine. It is attached to both the roof and the floor of the mine. The frass is deposited in an opposite corner." This mine was on the edge of the leaf, so that the margin of the leaf rolled down and in, unlike the common depictions of the mine as arching up between two leaf veins, with the axis of the mine leading away from the midvein. Almost all the other mines I detected were of the more typical form described.

Again there are multiple Chalcid and Ichneumonid parasitoids recorded.

This is a more typically shaped mine for Phyllonorycter nicellii, photographed a few days later on the 5th. Note that the tent is in great condition, with multiple browner creases, typical of the Phyllonorycter genus and of this species, so I am fairly confident about the ID.

and this is the upperside of the leaf showing the shape of the mine more clearly and the significant upfolding of the leaf together with the apparently typical "edge of the mine" nibbling. The nibbling can however also be seen apparently in the (usually smaller, squarer?) mines of Parornix devoniella.

Stereum serendipity

Wandering through the Northeast edge of a wet and muddy Dene Park today meandering through the Yew copse towards the Alders down by the waterworks, there were a few patchy finds to be made. Also there was an opportunity to weed three Laurel seedlings, every little helps! As you move off the car park, the first compartment has a number of Beech, but as you move up the hill there is quite a dense cluster of youngish Birch trees, with some standard Oak. Here is a view of the Birch, note the dense stems. It is quite easy to find some Stereum and Schizopora in this area.

On a fallen Alder by the weir I found what I think was a young fairly flexible Stereum subtomentosum (Pouzar) nicely orange overall but clearly white-edged. This is generally called the Yellowing Curtain Crust, and it should have released a bit of yellow fluid when cut - which of course I forgot to test for, even though I had deliberately brought my knife with me for the first time. |A scratch of the lower surface is the recommended approach.

The brackets should be quite narrowly attached, about 3 - 7 cm across and 1 - 2 mm thick, and irregularly wavy at the edges. These were also obviously much less hairy than Stereum hirsutum, hence subtomentosum, but the hairiness is apparently quite variable according to the interweb. Spores should be being released in summer and autumn and the spore print should be white to a very light tan in colour.

There were also apparently older outgrowths further along the trunk, showing the very significant differences in appearance as the "ears" age,

Another crust in Dene Park, Antrodia albida I think

A "Pore-Crust"??

Possibly Antrodia albida, one of the commoner Antrodia species in the UK. Pores quite "polygonal" 1 mm or more across, tubes a few mm long, Slightly light brown or strong cream in main colour, whitish underneath the tubes and at the edges.

Fungi at Dene Park.

I was pointed in the direction of this lovely burst of sunshine by a friendly lady dog walker. I believe this is Yellow Brain, Yellow Trembler, Golden Jelly Fungus, Tremella. It is possibly Tremella mesenterica, rather than its sister species, Tremella aurantia. 

T. mesenterica is said to be the more "slimy" of the two, while T. aurantia is regarded as more matte.

This was quite an attractive pinkish crust fungus, which I haven't tracked down yet.

Beech in Dene Park

The first Beech, Fagus sylvatica, trees I looked at had some old Phyllonorycter messaniella empty and browned mines, but further round on the north side, there were a couple of perhaps more recent and I think probable Phyllonorycter maestingella mines. And as usual there were some I couldn't make my mind up about.

I think this is pulled quite tight and is probably maestingella, lower side then upper side:

This (I think) is a second example:

Here are some old mines of what is probably Phyllonorycter messaniella.

Here is a new mine, with the caterpillar visible within it, next to a very old mine. There is no sign of any crease in the new mine.

However here is an old mine that still apparently shows sign of a central crease:

There were also some quite chunky brownish Stigmella mines, quite possibly Stigmella hemargyrella, as the egg seems to be away from the midrib. Notice the narrow start and first section of the mine, to the left, which apparently increases in size very abruptly.

Here is another example:

And a third, again starting at the leaf margin and finishing near the midrib, this time with a clear exit hole:

Nothing else, except the common leafhopper marks and the Hartigiola annulipes galls I think.

Late in Dene Park

A few mines about in the gloaming, getting a bit difficult to see!

On the Beech there were a few fairly long thin mines, all apparently deserted (!) of the Beech Midget, Phyllonorycter maestingella (Muller, 1764). I do wonder why this year I find so few occupied mines of this species, and I do seem to find more mines of P. messaniella on Beech, with its wider host range.

Fox Covert

Back to Dene Park, and diverting off to Fox Covert and the field beside it.

At the top of the field I found a few small folds at the tip of the lobes of Sycamore leaves, which I thought might be indicative of a Caloptilia species. This could be the Small Red Slender, Caloptilia rufipennella, found in the UK since the 1970s. The moth over-winters, perhaps in an evergreen such as Yew and reappears about spring. The mines are formed in sycamore leaves around, first as a small mine tucked into a vein axil, and you then get usually 3 "leaf tip folds - cones?" of increasing size in which the larvae continue to feed.

Dene Park on a sunny and warm February day

What a lovely few days, it really helps raise the spirits at this time of year when warm dry weather lasts for at least a few days!

I went down to the Alders, by the stream at the edge of the wood.

The first bird I saw was a Greater Spotted Woodpecker, but it was quickly away - too quick for a photograph.

This Blue Tit was searching the bark of an Alder tree, with the orange of the catkins forming a bit of a background to the photograph.

There were also Great Tits in the canopy - these seem to be commoner than the Blue Tits - or just louder or more visually obvious!

There wasn't much else in the woods today - lots of dog-walkers and families - but there were still Blackbirds and Robins, and of course Wood Pigeons overflying.

Dene Park

There seems to me to be relatively few visible macro-fungi in Dene Park, and today on a very muddy and rather miserable late afternoon turned up very little for me to photograph.


This close-up is of a crust fungus, probably the Hairy Curtain-Crust, Stereum hirsutum,  which really does seem to be very orange much of the time, whether as small tiers of brackets, or as resupinate crusts. This species is one of the commonest species recorded in the UK, found on hardwoods in very large patches and very commonly covering logs. There is another species, Stereum rameale, which is supposedly less hairy. I do find it a little difficult to be sure about differentiating these.

Just a couple of notes on Stereum rameale or aka ochraceoflavum. The habitat is said to be fallen twigs and small branches of broadleaved trees.  

Stereum hirsutum is found mainly on dead wood, but is occasionally seen on live wood, perhaps near wounds and it might be mildly parasitic. However it is mainly known as an abundant saprophyte. I wonder whether it is much more zoned and hairier at other times of year?

I assume from some of the pictures that the resupinate crust is often an earlier stage of development and the little turbinate bodies are the intermediate stage where the bracket is about to develop.

This is rather more highly magnified and showing the early stages I think - is that mycelium underneath these crusts? I think its more likely than being the hairy upper surface?

Stereum hirsutum is an all-year annual, and I think the crusty brackets fairly quickly discolour , darken and perhaps get covered in algae. However the colours of these are rather bright rich yellow to orange. Bibby has the hymenial (lower) surface as smooth, yellow-ochre to yellow-brown NOT reddening when injured. Bibby also has the upperside of the crusts as hairy-tomentose, zonate, yellow-orange, ochre to greyish-ochre. Buczacki has it as wavy, and distinctly downy-hairy.

This photo may indicate some dying off of the Stereum, possibly caused by the attack of another fungus or other pathogen.

Here are some more brackets, 2 - 5 cm diameter, on the same log, often with much darker brown centres, perhaps with a few velvety hairs glinting slightly in the flash light. I think that this is a different species of Stereum, but it might just be better developed Stereum hirsutum. The needles belong to the Douglas Fir I think, but that might be entirely incidental.. 

The flesh is tough, elastic and clearly inedible. There is no taste or smell. The spores, which I have never seen, are supposed to be white.

This is just a bit further up, and to the right of the last image.

In another place, this is a white resupinate fungus on fallen wood, unknown ID.

And in yet another spot, here are some mosses on an old stump, possibly a Sweet Chestnut.

and another species, this one with capsules,

And some stump lichen:
