Trichia macrospora: A new species of Slime Mold from Jiangxi Province, China.

Slime Molds are Eukaryotic organisms (organisms with cell nuclii) formerly classified as Fungi, but now regarded as not just unrelated to Fungi but paraphyletic (i.e. not all Slime Molds are related to oneanother). They spend most of their life-cycles as single-celled organisms, but when resources become sparce can coagulate to form a multi-cellular body which ranges from a few grams to a few tens of grams in size, which migrate in search of a suitable site then enter a spore-producing stage.

In a paper published in the journal Phytotaxa on 28 April 2016, Zhang Bo and Li Yu of the Engineering Research Center of Chinese Ministry of Education for Edible and Medicinal Fungi at Jilin Agricultural University describe a new species of Slime Mould from Jiangxi Province in China.

The new species is a Myxogastrian (Plasmodial or Acellular) Slime Mould, a group noted for producing large and conspicuous fruiting bodies, with the largest capable of producing single-celled fruit-bodies a meter across and weighing in excess of 20 kg. It is placed in the genus Trichia and given the specific name macrospora, meaning 'large-spores', the spores being larger than any other member of the genus.

The species was discovered living on a leaf of a Bamboo plant in the Junfeng Mountains of Jiangxi Province in July 2013. The species produces dark purplish-brown or brown sporangia on stipes (stems) 1-1.2 mm in length, which release rust-brown spores.
