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
