Observation 68206: Hemitrichia Rostaf.

Bright orange red and about 1 mm high on wet wood, all hardwood as far as I can tell. The 2nd picture is of the same bodies as the first, only 1 day later. These are close-up photos that have been cropped to enlarge the subject.

June 2nd addenda: Additional photos added of same log which show the dark metallic balls changing into furry dull yellow sporangia…, These appear to be the same species….,

Used references: I reread my references and I am inclined to agree with you. Tricia decepiens eventually turns into dark yellow fuzzy ball – and these don’t appear to be doing that. The fruit bodies on May 27 definitely have a metallic cast. On problem I am having is that it seems these things are judged as good food by the slugs! I think the black stubs are the bases of consumed fruit bodies.

My first experience with them here certainly supports that approach.

Myxomycetes are generally only identified when they are at the stage of dispersing spores. Colour, shape etc prier to this has little value so is rarely mentioned although plasmodium colour is often given when known.

Thanks damon, I agree

After re-reading Stephenson, which is admittedly brief and intended only as an overview, it looks like Hemitrichia sp. Some mushroom references know that all phases of a developing basiocarp need to be shown, but I have not found the same in a guide to myxomycetes. The one I have referred to appears to be the only one offered at the library or on Amazon. Can you suggest another?

Great follow up work!

Now I know that Hemitrichia visits this shade of blue black temporarily. It could be either H clavata, or H. calyculata, the former having a much larger cup than the late. From your photos, could be hard to say, but more that likely it looks like H calyculata.

Hemitrichia calyculata?

Trichia sp.

I am sorry if choose of title has added some confusion to this observation. It’s really the result of the lack of message threading eg. you can not comment on a comment. So I used the original observation title.

My suggestion of Metatrichia floriformis is due to the red stalks and purple /black fruiting bodies. It’s also a species that some time bunches up on a common stalk or more commonly produce single fruiting body’s in large numbers. I have seen them in the 1000s covering an area of 200mm by 75mm.

A number of different genus start out this red color. So he is just saying the ‘Trichiales’ in general. Why we are leaning toward M floriformis is because of the second picture. Of course there can be many mxyos in the same area, as Dan Molter has great photos of. If you look through the hundred of pictures on the link I gave you, you’ll be able to see the myriad possibilities within stages.

Is it Trichia or Metatrichia?

These are two different critters we agree, but the title and text of Clive’s comment seem to conflict, right? there is definitely some bunching going on – which is why you are leaning toward Metatrichia…, I will reread Stephenson.

I would also agree with damon Metatrichia floriformis would be a good guess.

Thanks damon and Dan

I am getting close to the limits of resolution with this camera – there are still a few tricks I have yet to try. The next step is a reasonable disecting scope….,

many globose red early stage trichias. Hemitrichia calyculata is very common as is T. decipiens. However the second photo is the key here. The dark purple color is closer to Metatrichia… I have only seen this species once, so cant say for sure.
