Stemonitis flavogenita E.Jahn?Slo.: ?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.

Date: June 15. 2009Lat.: 46.33506 Long.: 13.53008Code: Bot_356/2009-DSC0347Habitat: mixed wood in a mountain ravine, moderately inclined mountain slope, southwest aspect; cretaceous clastic rock (flysh); protected from direct rain by trees canopies and tall herbs, in shade, very humid place; precipitations ~3.000 mm/year, average temperature 8-10 deg C, altitude 450 m (1.500 feet), alpine phytogeographical region.Substratum: fallen, debarked and completely rotten deciduous tree trunk, hidden in tall herbs. Place: Bovec basin, west of Bovec, near the trail to Pluna village, East Julian Alps, Posoje, Slovenia ECComment: My initial tentative determination in 2009 Cribraria intricata was wrong. Based on new literature I've obtained the best fit seems to be Cibraria vulgaris. Fitting dimensions of sporocarps, distinct, well defined cup-shaped calyculus with irregular teeth, density of peridium mesh, color of sporangia and stalk tapering upwards, substratum and large colony speak in favor of this determination. Species has been already found in Slovenia (Ref.4) contrary to Cribraria intricata. However, determination with certainty would still require microscopic verification of traits. Unfortunately this hasn't been done.Ref: (1) B. Ing, The Myxomycetes of Britain and Ireland,The Richmond Publ.

ListerE: no name, DE: no nameSlo.: no nameLat.: 46.35884 Long.: 13.69819Dat.: Oct. 21. 2016Code: Bot_1021/2016_DSC5937Habitat: pasture, at the edge of the mixed forest, Fagus sylvatica, Ostrya carpinifolia and Picea abies dominant trees; moderately inclined slope at the foot of mountains, south east aspect; colluvial, skeletal, calcareous ground; mostly sunny place; relatively warm and dry place; exposed to direct rain, average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 615 m (2.020 feet), alpine phytogeographical region. Substratum: dead, thick, partly decorticated branch of Ostrya carpinifolia laying on ground; fund on top side of it; wood still firm, hard to cut; in its initial state of disintegration.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa; pasture west of Strgulc abandoned farm house, Soa 47, East Julian Alps, Posoje, Slovenia EC. Comment: Three aethaila found in a circle of about 0.4 m diameter. This myxomicete can be recognized by its vividly pink (not yet mature) aethalia, white hypothallus, characteristic spores, which are distinctly reticulate only on about 2/3 of their surface and persistent pseudocapillitium consisting of membranous perforated plates and threads. Reticularia splendens var. jurana can be distinguished from Reticularia splendens var. splendens by smaller size of aethalia and flaccid cortex.To my knowledge this is the second or third find of this species in Slovenia and the first one in the Julian Alps. Spores coarsely reticulated on about 2/3 of their surface and minutely warted (barely seen with my equipment) on the rest of it; globose to subglobose.

The latest monograph on Myxomycetes I have (Ref.:1) describes six varieties of this species, which differ mostly in cortex structure (single versus double layered) and color of different parts of sporocarp and plasmodium. Fuligo septica var. flava should have vivid yellow aethalia, yellow inner lime and yellow plasmodium. Two days before I took these pictures I had seen the plasmodium, which was in a form of vividly yellow colored patch of densely packed small half-spheres. The rest of traits of Fuligo septica var. flava also fit well to my observation.Spores minutely warty, globose to subglobose.

Didymium squamulosum (Alb. & Schwein.) Fr., Syn.: Cionium squamulosum (Alb. & Schwein.)

Substratum: bark of a dead trunk of Juglans regia in its initial disintegration stage laying on ground, partly sitting on Collema sp. (probably Collema crispum = Blennothallia crispa) thallus.Place: Lower Trenta valley, right bank of river Soa; between villages Soa and Trenta; near Trenta 2b cottage, East Julian Alps, Posoje, Slovenia EC.Comment: Habit and presence of lime crystals speak almost certainly in favor of the genus Didymium. Dimensions of spores inclined me toward Didymium melanospermum (Pers.) T. Macbr. at first. However, other traits, particularly furrowed stalks, whitish stalk color (should be bark to black) and presence of lime in them (it should be absent), changed my initial supposition in favor to similar Didymium squamulosum (Alb. & Schwein.) Fr. in spite of the fact that measured spore dimensions doesn't fit so nicely to the second option. Another discrepancy of the find (related to booth species) is the fact that vast majority of the sporocarps appeared sessile, while they should normally be distinctly stalked and only rarely 'sessile'. According to literature Didymium squamulosum is considered a very variable species and apparently sessile sporocarps are found occasionally too, so they may not be a severe argument against this determination.Description: Sporocarps up to 1.1 mm tall, most of them seemingly sessile having rudimentary stalks hidden in strongly umbicilate sporocysts below; only a few distinctly stalked; sporocysts sub-globose or oblate, 0.6-1 mm in diameter, when wet bluish-gray, half dry pale-gray, when dry white; with simple, membranous, colorless to light-yellowish, translucent peridium covered by a thick layer of crystalline lime; crystals usually larger than spores; (hypo)columella present, flattened, perimeter about 1/3 or slightly less of the sporocysts perimeter; white to beige, light brownish (best seen in transparent light); capillitium thin, scantily branched with rare, small nodular swellings; attached to peridium. Stalks short, mostly hidden; some distinct but not longer than 2/3 of sporocysts diameter, longitudinally striate, No confluent plasmodial form observed at the site of stalk attachment to substrate.To our knowledge, up to present three observations of this rare (or overlooked) species in Slovenia have been described up to now (Ref.:5, Ref.:6 and Ref.:7). Microscopy: Spores densely warted (< 0.5m high warts), globose to sub-globose dark brown to black on mass (dry); dimensions: (10,5)10,8 - 12(12,6) (9,9)10,4 - 11,5(11,9) m; Q = 1 - 1,1; N = 21; Me = 11,4 10,9 m; Qe = 1.

Stemonitis lignicola Nann.-Bremek, syn.: Stemonitis splendens MorenoSlo.: no name.Dat.: July 20. 2016 - 19:47|Code: Bot_1075/2017_DSC8324Lat.: 46.35975 Long.: 13.70152Habitat: mixed wood, Fagus sylvatica dominant tree following by Picea abies; slightly inclined mountain slope, southeast aspect, old colluvial, calcareous, skeletal ground; in shade; relatively warm and dry place; partly protected from direct rain by tree canopies, average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 602 m (1.970 feet), alpine phytogeographical region. Substratum: old, cut off, standing trunk of Fagus sylvatica, partly debarked.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa, next to the trail from Trenta 2b cottage to Strgulc abandoned farm house, Soa 48, East Julian Alps, Posoje, Slovenia EC. Comment: Stemonitis lignicola is generally considered a quite rare species. However, all macro and micro traits of this find as well as substratum fit well to Stemonitis lignicola descriptions in literature. An exception may be slightly large spores. However, the observed differences in diameter are roughly of the same size as between an example shown in Ref. 3 compared to average given in Ref.: 2. Capillitium extensions (resembling warts or free ends) were found rare and small. Note that Ref: 2 doesn't mention capillitium extensions at all and talks about smooth capilitial threads, while Ref.: 5 claims presence of capillitium extensions for this species.Sporocarps cylindrical, somewhat curved, about 12 mm high and 0.35-0.45 mm in diameter, stalks 2.5-3 mm long; surface capilitial net distinctive, uniform, small meshed, with rare extensions; capilitial internal net sparse, thick, with some membranous expansions; columella reaching the tip of sporocarps, gradually tapering toward the top, frequently bended in the upper part of the sporocarp; stalks short, blackish brown to black, shiny; hypothallus membranous, shiny; plasmodium white; spores on mass abundant, dark brown. Spores evenly, densely but minutely warty (verruculose); globose to subglobose. Dimensions: 7,9 [8,2 ; 8,3] 8,7 x 7,3 [7,8 ; 8] 8,4 microns; Q = [1 ; 1,07] 1,1; N = 36; C = 95%; Me = 8,3 x 7,9 microns; Qe = 1,1. Taken from dried material by gently tapping sporocarps. Average outer net (peridium) mesh 21 microns in diameter (SD=7 microns, N=30).

Mastigamoeba (massed-ig-a-me-ba) One of about 5 genera of pelobionts. These organisms are unusual in lacking mitochondria, dictyosomes and were for some time regarded as the most primitive of all eukaryotes. Most species which have been studied can adopt a variety of morphologies - including flagellates, amoebae, and cysts. The flagellates typically have one very long flagellum which beats in a fairly ineffectual fashion - and mostly progress by gliding. Body of cell most usually adopts an amoeboid form - such as that illustrated here. Typically found in habitats with little or no oxygen. Phase contrast.
