Stemonitis flavogenita E.JahnEN: ?, DE: ?Slo.: ?Membranous expansions in the capillitium (black arrows) and a single spore still attached to the capillitium (red arrow).Dat.: Aug. 11. 2014Lat.: 46.36119 Long.: 13.70107Code: Bot_823/2014_DSC2764Habitat: old partly overgrown pasture, near mixed wood edge, moderately southeast inclined foot of a mountain; open, dry, sunny place; shallow, skeletal, calcareous ground, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 630 m (2.070 feet), alpine phytogeographical region. Substratum: north side of a stump of Picea abies (on decorticated part) cut down three years ago.Place: Lower Trenta valley, between villages Soa and Trenta, upper part of 'Na melu' place, East Julian Alps, Posoje, Slovenia ECComment: Highly distinctive traits of Stemonitis flavogenita are typically zig-zag bent columella with a kind of plate at the end just before the end of sporangia (Ref.:1). It is not gradually tapering toward the end of sporocarp as with other species of genus Stemonitis. It is also distinguished by the presence of membranous expansions in the capillitium. Also agreement of macroscopic properties fit well to literature, so I hope the determination is correct. This observation may be interesting since this species is listed neither in Boletus Informaticus data base, Mycotheca and lichen herbarium (LJU-Li) of Slovenian Forestry Institute nor in official Slovenian fungi checklist.Sporocarp color rusty, oac719; spores on mass chocolate brown, oac635. Stalks 2.5 to 3 mm long, total length of sporangia 9 mm, all of them were fairly the same length, very closely tufted, their tips blunt. The whole clump had 14 mm in diameter.Spores finely warted, globose. Dimensions: 8,4 [8,8 ; 9] 9,5 x 8,2 [8,6 ; 8,7] 9,1 microns; Q = 1 [1,0] 1,1; N = 32; C = 95%; Me = 8,9 x 8,7 microns; Qe = 1.

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.
