Plasmodial Slime Molds

Habitat: 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. - Comment: 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.

Zig-zag bending of the columella near and the small plate at its end. Capillitium is damaged and misplaced. - Typical plates at the end of columellae can be seen also without microscopy at the ends of damaged sporangia (marked by arrows). - Habitat: 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. - Comment: 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.

Habitat: Alpine upland, partly steep grassland partly Pinus mugo stands on steep rock, east oriented slope, fully exposed to sun and precipitations, just one or two meters off still snow covered terrain, precipitations ~3.000 mm/year, average temperature 2-4 deg C, elevation 1.530 m (5.000 feet), alpine phytogeographical region. Substratum: Dead rotten grasses and twigs laying on ground where the snow melted just a few days back. Description: Outer white shell of 'balls' breaks off easily. Beneath it is another irregular white-black check-board like 'crust',. Underneath it there is a sometimes dense, sometimes loose net of shiny black fibers mainly radially oriented. In the middle there is an entirely black mass with apparently some hollow spaces. No distinct columella could be seen. Specimens brought home produced abundant 'black smoke' when moved after two days of drying. It is interesting that the place where I photographed the stuff had still to be covered by rapidly melting snow just a few days before I took the pictures.

Habitat: mixed wood in a ravine, cretaceous clastic rock (flysh), rain protected by trees canopies and tall herb, in shade, very humid, 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. - Comment: Eventually Cribraria tenella but stalks seem too robust. C. atrofusca seems to be another option. Determination uncertain. No microscopic verification. - Ref: http://www.myxomycetes.it/foto_big.php?foto=Cribraria/cribraria-tenella.jpg
