Mariannaea elegans

Ciri dan struktur

Mariannaea elegans is an anamorphic fungus (i.e., it reproduces asexually). When M. elegans is grown on a Petri dish in 2% MEA (Malt Extract Agar; medium used in a Petri dish) and PDA (potato-dextrose agar) at 22 C the growth and morphological characteristics listed below are observed. The colonies of M. elegans grows better in MEA than in PDA. On average colonies of M. elegans can be observed with the naked eye having a diameter of 2.5–6 cm after 10 days of growth. They appear thin and velvety (i.e. smooth) or floccose (i.e. woolly) or matted (i.e. powdery) and are odourless. Sometimes the colonies make a ring shaped pattern as might be seen on a jawbreaker candy. Specimens isolated from wood possess brown colonies whose brown pigment fuses into the surrounding agar. However, specimens isolated from soil possess reddish-purple colonies whose pigmentation does not diffuse in to the agar surrounding the colonies of M. elegans. Colonies are white to cinnamon buff (peanut butter colour) and possess either smooth or rough walls. The mycelium is either smooth-walled or rough-walled, white to olivaceous (the green colour of the mould on blue cheese) or pink. Conidiophores are arise from mycelia immersed in the agar. They are light brown, with a smooth or verrucose (i.e., bumpy) surface and grow to a maximum of 1000 μm long and reach a maximum of 10 μm in width at the base. Conidiophores can also arise from aerial hyphae. These conidiophores grow to 250 μm in length and 7 μm in width. Additionally, they can grow to reach a maximum of 1400 μm in length and 23 μm in width at their base.

Habitat dan peran ekologis

Mariannaea elegans grows on decaying coniferous bark or wood, forest soil, house dust, prairie and grassland soils, calcareous soil, running water that has little pollution, waste stabilization ponds, acid mine drainage stream, fields treated with digested sewage sludge, in arable soils, and on pine chips. Mariannaea elegans has been isolated from various regions in Canada: Quebec, Ontario, Manitoba, Saskatchewan, and British Columbia. Both varieties have both been recorded in Germany, the Netherlands, the United States, and Canada. However, only M. elegans var. elegans has also be found in France, the British Isles, Italy, Poland, and South Africa, whereas, M. elegans var. punicea has exclusively be found in Democratic Republic of the Congo. The ecological role of this species is not well known. It is involved in wood biodeterioration either through the formation of soft rot cavities or through cell wall erosion. It may also influence the growth of other fungi. For example, at 25 C it inhibits mycelial growth in the mushroom, Pholiota microspora; but at12 C it enhances mycelial growth of P. microspora. It is capable of preventing sapstain (a blue to greyish-black colour) formation on wood treated with M. elegans.
