Metatrichia is a genus of slime moulds within the family Trichiaceae. I found this slime mould growing on a decaying log in native forest. The blackish spheres at the tip of stalks contain clusters of spores. The spheres in Metatrichia floriformis are only 1 mm in width or less. The slime mold is called 'floriformis' because the black outer shell can look like flower petals when it breaks open to expose the spores, a bit like the second head from the left. That was the look I had envisaged but did not really get. What I got was two sets of twins, one joined at the lower stem and the other fully joined right up to the head. Technical notes: lit with 2 LED panels, 26mm extension tubes and Raynox 250 closeup lens added to an Olympus 60mm macro lens to take the magnification beyond 1:1. Focus stacked in Zerene Stacker from 65 images. Unfortunately the metadata are lost in the stacking process.
Transition to maturity

The photo shows fruiting bodies of the slime mould Hemitrichia calyculata at different points of maturity. When conditions become unfavorable, slime moulds form sporangia (fruiting bodies), clusters of spores, often on the tips of stalks. There is about a day in between each photo. The least mature fruiting bodies are on the left and the most mature ones on the right. At maturity the membrane that encases the spores splits open to release the spores, a process called dehiscence. The many threads or wild hair you can see in the right photo are part of the capillitium, filamentous structures that usually develop with spores within sporangia. They are thought to aid the retention of spores in the sporangia. The microscopic structure of the capillitium is not only complex and beautiful but also helps identification. By retaining spores the capillitium will allow gradual dispersal of spores over a longer period of time.
Hemitrichia is a slime mould with a wordwide occurrence that grows on decaying wood. The photo shows the stalked fruiting bodies (sporangia) early in their development. The stalk is translucent and filled with spore-like cysts. The pale-orange peridium is a protective layer that encloses a mass of spores. It will undergo colour changes from pale orange through bright orange to yellow brown as the fruiting bodies mature and release their spores within hours or days. The 'heads'are well under 1 mm in diameter. Alison Pollack's photos of slime moulds and tiny fungi are worth seeing: www.instagram.com/marin_mushrooms/?hl=en&img_index=1
