I cropped it. Then applied a Gaussian blur to everything except the actual flower and stem. Trying to simulate a shallow depth of field.

We only have few in our garden and my wife noticed them today so I went and and captured them while they lasted.

I agree they are very attractive flowers.

Eyeball to Eyeball: a Close Look Required

Last year I, several times, found a tiny Ascomycete fungus. Of various sizes, but no more than 1mm, it was this characteristic whitish, fuzzy appearance with a black spot. I found it on rotting twigs on the ground. I was going to collect some naturally dried, black, shiny mature ones for identification.

As I do frequently, I recently took a look in the leaf litter and wood chip mixture in our garden. In an area the size of a hand span, I found two colonies of tiny, whitish fruiting bodies. One was clearly a slime mould, the bodies on distinct stems. The other looked very much like the fungus.

A hand lens is inadequate for these tiny structures. Photography is extremely difficult, with less than 1mm being the most DOF a single frame can capture. Stacking would be the answer but I am not set up for it. These images were shot for identification purposes and not primarily to post here but they may be of interest. There is a great deal of diffraction blur in the RAW files. Much can be removed with software but the images are far from pin sharp.

The first two images are of the fungus, which I believe to be of Lasiosphaeria ovinum, a species which occurs at all seasons. The second image is where I have cut a piece of the leaf hosting the suspected L. ovinum and put it close to the right side of the colony of the slime mould (to get no more mention in this topic).

The remaining images are of the other species which has the fruiting bodies clothed in rather leaf-like (squamose) white plates. It took me a long time but I found images of a Slime Mould which looks exactly like this*. This is Didymium ilicinum, considered by some people to be a form of D. squamulosum. The species was discovered in England, on Holly leaves, but also occurs in leaf litter. I have included a stereo of it. The 3D effect is poor but the combined image has a little more DOF.

It proved extremely difficult to show that this species has stems, all of which are short and most of which are obscured by the fruiting body capsule.

I had to repeat two or tree sharpening processes and adjust contrast and brightness to squeeze the detail out. That is not something I normally do, even for SMs.

For what the stereo is worth, it is best viewed from further back than usual.

*The first image, under another species name, was in my latest book (with an eye-watering price tag!).

Olympus EM-1, Olympus 4/3 50mm f2 macro, with Olympus 4/3 x2 TC and Raynox MSN-202 for the closer shots, triple TTL RC flash, hand-held.

Yesterday was a warm and sunny day so I entered the greenhouse to check for perfume. There was no need to sniff closely, the whole greenhouse was rich with a heavy, exotic aroma. Even today, with constant drizzle and no sun, the perfume fills the air, if much less intensely.

Re: Communal flowers, trees, plants and fungi thread

A Somewhat Regimented Fungus Colony

Our apple tree has been dead for a year or two, probably killed by Silver Leaf. Huge chunks of bark are now peeling away. Today I saw a colony some 160mm x 50mm of what I thought was a slime mould on a bare patch at the top of the trunk. I attach some images, the higher magnification FOV ca 5mm.

Of particular interest is the reticulated layout of the groups of sporocarps, something I don't recall seeing before. (The first two images have a large crack in the tree due to shrinkage).

EM-1, Olympus 50mm f2 macro, for the higher magnifications: plus x2TC and with a Raynox MSN-202 for the highest. The first two were by daylight (sun through thin clouds), the others by triple TTL RC flash.

The stereo is crosseye.

Re: Communal flowers, trees, plants and fungi thread

Plasmodium of Slime Mould

I found this by turning over some moist wood chips. While visually unexciting, it is a stage I have not photographed before. This is the asexual, vegetative stage.

https://www.britannica.com/science/plasmodium-mycology

The various swellings are fruiting bodies starting to differentiate. The bases of the forming stems look rather like those of Trichia and related genera. Some of the fruiting bodies are shaped a bit like Arcyria. I think the latter is the more likely.

I replaced the material in habitat but could not find any on following days. It is known that disturbing Myxomycetes can disrupt their development.

EM-1, Nikkon Printing-Nikkor 150mm at f11, set for 1:1 on full frame, giving 2:1 on m4/3. Triple flash. Hand-held with support.

The stereo is crosseye.

Harold

Acyria denudata

This colony was found in local woodland.

Witch’s Butter Tremella mensenterica with Stereos

This is a jelly fungus, commonly found on attached, or recently fallen, tree branches. The name means “trembling middle intestines”. There are a number of similar-looking species, usually identified as T. mesenterica in the field, which can only be separated by microscopic examination.

Other names include “Yellow Brain”. Generally rated as “inedible” it is use to give texture in some Japanese soups.

Like other species in the genus, this is a parasite on another fungus. T. mesenterica always feeds on crust fungi of the genus Peniophora (Resupinate Fungus), of which there are dozens of native species. That no other fungus can be seen in the images means that the parasite infected the mycelium inside the branch before it could form a fruiting body (crust) on the outer surface of the bark.

There is not a great deal of form to this species. As an image subject, it is more like a rock protruding from a beach! The difference is that I can pick up the branch, carry it to where I want to work (sit down too) tilt it to desired angles and arrange the lighting around it. All this and no sand in my shoes!

The stereo pairs are crosseye.

Olympus EM-1 (manual mode), Olympus 4/3 x2 TC, Olympus 4/3 50mm f2 macro, f16, triple RC TTL flash, hand-held.

Harold

Re: Communal flowers, trees, plants and fungi thread

Marchantia polymorpha ssp. ruderalis Cupule

I have previously posted images here of the common species of Liverwort, Marchantia polymorpha, the one with the palm tree-like males reproductive organs.

Yesterday, I spotted a very recognisable Marchantia thallus (leaf, sexual stage) in with a potted monkey orchid. I seemed as bit different from previous findings, in adjacent flower pots. There was just the single cup (ca 1.5mm diameter) and no other differentiated structures. The texture of the surface of the thallus looked rather coarse too. The green discs inside are gemmae, asexual, vegetative buds which are dispersed by rain splashes.

As I photographed it I was aware that the rim of the cup was less green than usual and the very edge was finely tooted, with finer teeth, or fringes, on the main ones.

I searched the internet for images of the cupules but I found nothing useful.

I looked it up in my specialist book. Under M. polymorpha there was no mention of such detail but the area of blackish spots along the midrib of the thallus (third image) did separate it off as the subspecies. The other two subspecies have either no line or a solid one. This is the first time I have, knowingly, seen this subspecies. However, it is supposed to be the most common one in gardens, plant nurseries, etc., where it can be a weed.

There is not quite enough DOF at this magnification to really show this structure as I would like, especially for the crosseye stereo, but I think posting some images is worthwhile.

EM-1 (manual mode), Olympus 4/3 x2TC, Olympus 4/3 50mm f2 macro, mostly at f16, Raynox MSN-202 (except for low magnification) triple TTL RC flash, hand-held.

Harold

You are doing a great job photo-ing these micro organisms. So interesting to see what huge amounts of life that is lurking almost unseen beneath our feet.....

Thanks.

Not too many camera phone images of them !

I hope to encourage macro of more than the usual subjects.

Re: Communal flowers, trees, plants and fungi thread

Anthurium Xavia Growing in a pot in our pergola, likes shade, but can be grown indoors. Poisonous from calcium oxalate crystals, the sap is an irritant to the eyes and skin. It has air purifying qualities and has an affect on formaldehyde, ammonia and volatile organic gases. Several of the these plants in a building, can reduce harmful substances by more than 50% in 24 hours.
