Stemonitidaceae

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.

Slo.: nitkarica - Habitat: 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. Comment: Habit of this find resembles to some extent to Stemonitis splendens or Stemonitis flavogenita or Stemonitis lignicola. Size, stalk length compared to total length, diameter in relation to the length of sporocarps, slightly bended sporocarps seems to fit within the limits of variability of these species. However, all three species are lignicolous, while this find was fruiting on moss. Only the synoptic key in Ref.5 states that S. flavogenita can occasionally thrive on green plants also (mosses included?). Browsing through my literature moss as a substrate is explicitly mentioned only for Stemonitis herbatica and Stemonitis pallida. Unfortunately, habit of both is not similar to my pictures. Both species are much thicker and shorter and also stalks of both are short compared to total length of sporocarps. Since I haven't done any microscopy and my experience with the habit of these species is very limited this find remains undetermined.Ref.:(1) B.

Capillitium is a loose network of threads with many expansions. The peridial network of sporangia is very fragile and was probably damaged. Thus it is not seen in the picture. - 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.

Slo.: nitkarica - Habitat: 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. Comment: Habit of this find resembles to some extent to Stemonitis splendens or Stemonitis flavogenita or Stemonitis lignicola. Size, stalk length compared to total length, diameter in relation to the length of sporocarps, slightly bended sporocarps seems to fit within the limits of variability of these species. However, all three species are lignicolous, while this find was fruiting on moss. Only the synoptic key in Ref.5 states that S. flavogenita can occasionally thrive on green plants also (mosses included?). Browsing through my literature moss as a substrate is explicitly mentioned only for Stemonitis herbatica and Stemonitis pallida. Unfortunately, habit of both is not similar to my pictures. Both species are much thicker and shorter and also stalks of both are short compared to total length of sporocarps. Since I haven't done any microscopy and my experience with the habit of these species is very limited this find remains undetermined. Ref.: (1) B.
