arcyria stipata

Arcyria imperialis (Arcyria stipata)

Description:

Sporocarps crowded, stalked, 1.5-3 mm total height, erect or ± superimposed and then subsessile or sessile and often forming a pseudoaethalium, copper-coloured or reddish in the fresh state, metallic, often with lavender or rose tints, browning with age. Hypothallus dark brown, confluent. Stalk 0.1-1.5 mm tall, dark brown. Peridium, in separate sporothecae, evanescent above and leaving a shallow calyculus, persistent in pseudoaethaliate forms and then splitting into lobes. Capillitium attached at the base, somewhat elastic, forming a loose net, with bulbous thickenings and numerous free ends, the upper part often breaking away with the peridium, the tubules 3-5 µm diam., bearing 3-4 spirals, these ± intermixed with spines, cogs, half-rings or occasional rings and reticulations. Spores pallid, 6-8 µm diam. Plasmodium yellow

Habitat:

The species is distributed worldwide. It is found throughout the year on dead wood of coniferous and deciduous trees. The amoebozoa is found often together among other species of the generas "Trichia", "Arcyria" and "Cribraria" and "stemonitis typhina" ( http://www.discoverlife.org/mp/20q?searc... ),( http://slimemold.uark.edu/fungi/default.... ),( http://www.hiddenforest.co.nz/slime/inde... ),( http://myxomycet.com.ua/eng/taxa/arcyria... )

Notes:

Slime mold or mould is a broad term describing protists that use spores to reproduce. Slime molds were formerly classified as fungi, but are no longer considered part of this kingdom. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the myxomycetes, which are the only macroscopic slime molds. Slime molds have been found all over the world and feed on microorganisms that live in any type of dead plant material. For this reason, these organisms are usually found in soil, lawns, and on the forest floor, commonly on deciduous logs. However, in tropical areas they are also common on inflorescences, fruits and in aerial situations (e.g., in the canopy of trees) and also grow in air conditioners, especially when the drain is blocked. In urban areas, they are found on mulch or even in the leaf mold in gutters. One of the most commonly encountered slime molds is the yellow Physarum polycephalum, found both in nature in forests in temperate zones, as well as in classrooms and laboratories. Most slime molds are smaller than a few centimeters, but some species may reach sizes of up to several square meters and masses of up to 30 grams. Many have striking colours such as yellow, brown and white

hi lars, i definitly know that fact: i always write it in the "notes", that slime molds are no fungi, but it were!! slime mold get researched by "mycologen", they stand in fungi-books, and as "Amobozoas"they are really fungi-like.
-{ "Slime molds are not true fungis, but are usually grouped with them.True, slime molds are Myxomycota, which are currently classed as Protozoans, but current consensus here is to place them with Fungi. I can see what Yassar thinks "} this is what old project noah ranger: lori.tas says about it.--
i will not change them into category others, feel free to do it for me !! (but then all of my slime molds please ?! sorry for being so directly. no offense !!! greeting from nl

Alex, just to remind you - slime molds are not classified as fungi anymore. I had to change mine into "other" as well.
