Hemitrichia-clavata_15

Description:

Hemitrichia cf clavata (Pers.) Rostaf., syn.: Trichia clavata Pers., Hyporhamma clavatum (Pers.) LadoEN: Yellow-Fuzz Cone Slime, DE: Gelber ScheinhaarstublingSlo.: kitajska zlatovkaDat.: Oct. 5. 2009Lat.: 46.33439 Long.: 13.48114Code: Bot_388/2009_DSC5885Habitat: Mixed, predominantly Fagus sylvatica forest, in shade, partly protected from direct rain by tree canopies, average precipitations ~3.000 mm/year, average temperature 3 -5 deg C, elevation 1.330 m (4.400 feet), alpine phytogeographical region. Substratum: fallen, heavily rotted trunk of a deciduous tree, probably Fagus sylvatica. Place: Bovec basin, Gozdec forest, above the road from Mt.Kanin cable car station B to the foot of Mt. Kopa, East Julian Alps, Posoje, Slovenia EC. Comment: There was no microscopy done for this observation, hence the determination is unreliable. Myxomycetes pass through very different shapes and colors during development of their sporocarps. In most cases it is impossible to determine them to species level without microscopic observation of their spores and structure, at least for me. These pictures show immature sporocarps. Sporocysts have not yet opened, capillitium and spore mass are not yet visible. Also stalks are mostly not yet developed. This makes determination even more difficult. Nevertheless, the size and the shape of the oldest sporocarps and stalks with reddish tint points toward Hemitrichia clavata. But, it is possible that the pictures show other Hemitrichia or Trichia species like similar Trichia decipiens or Hemitrichia calyculata. Picture #10 shows eventually another species. On picture #8 one can see also two species of (probably) Ascomycetes - a larger jelly fungus and smaller black blobs (both lower left). What a picturesque life one can find just on a small piece of rotten wood! A white 'mycelium' shown on the same picture (and others - upper left) probably belongs to another kind of fungus. Although Hemitrichia clavata has white plasmodium these fibers don't seem to me to be its plasmodium. Ref.:(1) B. Ing, The Myxomycetes of Britain and Ireland,The Richmond Publ.
