Arcyria ferruginea (ripe)

Arcyria ferruginea


Sporocarps usually in dense groups, sharing a common hypothallus. Sporocarps at first spherical, ovate, short-cylindrical or pyriform, 1-2 mm tall, 0.5-1.0 mm diam., brownish orange, terracotta, ochraceous, olive or olive-brown. Stalk 0.3-0.8 mm long, concolorous with the sporotheca. Calyculus large, with a reticulum on the inside and a smooth rim. Capillitium elastic, connected only to the stalk apex, basal tubules 2-3 µm diam., 5-6 µm in the upper part, with free ends and sometimes with ± circular thickenings, decorated with warts and ± spirally arranged rings and half-rings and usually reticulate ridges. Spores pale ochraceous, 9-11 µm diam. Plasmodium pink, salmon or cream-coloured.---- [Description from ( ) ] --- Here the SPORES-----> ( )

An often easy to recognise family as the spore mass is typically brightly coloured, producing stalked or sessile sporangia. A capillitium often consisting of tubular threads branching at wide angles, smooth or ornamented with spines, warts, cog-like prominences or half-rings, free or attached threadlike elements --- ( ) ------- 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 ( ) --- this is more than a month later, they have fully matures, and because they were at the underside of the tree, they aren't covered from the snow. --> ( )
