Steccherinum subcrinale (Peck) Ryvarden, Synonymy: Hydnum subcrinale Peck, Irpex subcrinalis (Peck) Saaren. & Kotir., Mycoleptodon kavinae Pilt, Bull. Odontia subcrinalis (Peck) Gilb., Steccherinum kavinae (Pilt) M.P. Christ..(unnamed species of) 'Hedgehog stool', DE: Ockerbrauner Resupinat-Stacheling, Ockerbrauner Resupinatstacheling, Ellipsoidsporiger Schnallenloser ResupinatstachelingSlo.: vrsta bodikaDate: July 27. 2010Lat.: 45.71421 Long.: 14.39441Code: Bot_436/2010_DSC3359Habitat: Old, mixed wood, Picea abies dominant; locally almost flat terrain, calcareous ground; in shade, fairly humid place; partly protected from direct rain by tree canopies; average precipitations 1.600-1.800 mm/year, average temperature 8-9 deg C, elevation 740 m (2.450 feet), Dinaric phytogeographical region.Substratum: on wood of a tree stump covered by mosses; in the final stage of disintegration; species undetermined but probably Picea abies or Abies alba. Place: North of Cerknica lake; SE of village Laze pri Gornjem jezeru; between hills marni gri, 768 m and Sovinek, 780 m, Notranjska, Slovenia EC. Comments: Steccherinum subcrinale is a loosely attached to its substratum, resupinate, effused teeth fungus. It can be distinguished from other Steccherinum species (in my region Steccherinum ochraceum and Steccherinum fimbriatum) by short, from (0.2)0.3 to 0.5(0.6) mm long cylindrical aculei (spines or teeth). Alternative species have pointed, conical (and mostly larger) 'spines'. The same seems true for similar species of genus Irpex. Steccherinum subcrinale also never forms shelf-like, small pilei but remains strictly resupinate.Steccherinum subcrinale is a rare species everywhere in Europe and denoted 'extremely rare' in Germany (Krieglsteiner 2000), Italy (Bernicchia 2010) and north Europe (Eriksson et al 1984). It is listed neither in Poler ed. 1998 nor in Ogris 2008 for Slovenia. Unfortunately, at the time I photographed this observation I was unaware what it might be and I didn't take samples to do microscopy and make exsiccate. Hence the determination remains uncertain although macroscopic traits from photos seem to fit quite good.Ref.: (1) G.J.

Both have very variable and irregular habitus and can be found pileate, effuse reflexed and also totally resupinate. Bjerkandera adusta is more common and can be distinguished from Bjerkandera fumosa by its very, very small more or less angular pores (5-7/mm), darker gray pore surface with pale margin and smaller spores. But distinguishing is not always easy. Bjerkandera adusta can be found during the whole year but it sporulates only at temperatures below 10 deg C (Ref.:4). So, one can hope to get spore print only during colder seasons of my country. Generally in the literature the pilei are described as azonate or only weakly zonate, however when they are very young this apparently doesn't hold (see Fig.4).Growing in imbricate groups of several fruit bodies; pilei 1.2 - 2.8 cm across, trama pale brown, corky-fibrous (cannot be chewed over but can be nicely cut with a razor), up to 4.5 mm thick, pore layer dark-grey and distinctly darker then trama, about 1 mm thick; stipe absent; taste mild, slightly unpleasant but not bitter; smell on sour earth similar to Trametes versicolor; SP faint, whitish.

Bjerkandera adusta (Willd.:Fr.)

Both have very variable and irregular habitus and can be found pileate, effuse reflexed and also totally resupinate. Bjerkandera adusta is more common and can be distinguished from Bjerkandera fumosa by its very, very small more or less angular pores (5-7/mm), darker gray pore surface with pale margin and smaller spores. But distinguishing is not always easy. Bjerkandera adusta can be found during the whole year but it sporulates only at temperatures below 10 deg C (Ref.:4). So, one can hope to get spore print only during colder seasons of my country. Generally in the literature the pilei are described as azonate or only weakly zonate, however when they are very young this apparently doesn't hold (see Fig.4).Growing in imbricate groups of several fruit bodies; pilei 1.2 - 2.8 cm across, trama pale brown, corky-fibrous (cannot be chewed over but can be nicely cut with a razor), up to 4.5 mm thick, pore layer dark-grey and distinctly darker then trama, about 1 mm thick; stipe absent; taste mild, slightly unpleasant but not bitter; smell on sour earth similar to Trametes versicolor; SP faint, whitish.

Steccherinum bourdotiiDat.: Jan. 05. 2012 Lat.: 46.34676 Long.: 13.56571Code: Bot_587/2012_DSC2154 Habitat: At the side of a group of Pinus nigra trees, south oriented mountain slope, fairly sunny and relatively warm place, calcareous ground, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 600 m (1.950 feet), alpine phytogeographical region.Substratum: Dead stump of a cut down deciduous tree (possibly Ostrya carpinifolia) mostly still in bark and partly covered with mosses, also heavily infected with Trametes versicolor (as effuse-reflexed to pileate form), however fungus spread also to pieces of fallen off bark, herbaceous plant roots and old leaf petioles (as a resupinated form).Place: Bovec basin, at the foot of Mt. ukla, Ravni Laz place, above the dirt road to Plajerjeva skala, East Julian Alps, Posoje, Slovenia EC Comments: Subglobose to ovate and significantly larger spores (see spore measurements chart), smaller diameter pseudocystidia, conical and longer than 1 mm aculei (see Ref.:(2)) distinguish this observation from more frequent Steccherinum ochraceum well. All forms from pure resupinated to distinctly pileate present. Caps of pileate form zonate, up to 14 mm wide and 12 mm off the substrate, often confluent up to 2 mm thick, context thin, upper side beige-pink with some brown strips and green (algae?), with thin whitish margin. Hymenium aculei up to 1.5 mm long, mostly conical, ocher-pink (oac764); hymenium in resupinated form with white edge. Smell indistinctive on soil and rottenness. SP whitish. Spores smooth, subglobose to ovate, dimensions: 4.4 (SD = 0.3) x 3.7 (SD = 0.2) micr., Q = 1.21 (SD = 0.07), n = 30.

Irpex lacteus (Fr.; Fr.) Fr. Elench. Fung. p145, 1828, syn.: Sistotrema lacteum Fr.Milk-white toothed polypore, DE: Milchweisser EggenpilzSlo.: belkasti rapovecDat.: Feb. 23. 2014Lat.: 46.35947 Long.: 13.70424Code: Bot_784/2014_DSC0038File names: from Irpex-lacteus_raw_1.xxx to Irpex-lacteus_raw_8.xxx.andDat.: Feb. 27. 2014Lat.: 46.35947 Long.: 13.70424Code: Bot_786/2014_DSC0132File names: from Irpex-lacteus_raw_10.xxx to Irpex-lacteus_raw_11.xxx.Habitat: alpine valley, an opening in mixed forest with predominantly Fagus sylvatica followed by Picea abies; modestly inclined southeast oriented mountain slope, overgrown calcareous ground composed of scree, rocks and boulders; mostly in shade, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 560 m (1.950 feet), alpine phytogeographical region.Substratum: cut down trunk of Fagus sylvatica lying on ground, in its late initial phase of integration; the trunk was massively infected also with Trametes hirsutum.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa, near 'Na melu' place, East Julian Alps, Posoje, Slovenia EC. Comments: fruit body mostly resupinated but also effused-reflexed; very large, about 1.5 m x 20 cm, about 2-3 mm thick, context thinner than pore layer; small 'pilei' up to 8(12) mm off the substrate; hymenophore with initially distinctly irregular angular, almost labyrinthine pores soon becomes irpiciform to hydnoid (compare Figs. 8. and 10.); smell indistinctive, taste initially indistinctive, after some time slightly unpleasant; 5% KOH reaction on context and pore layer mild, color changed to somewhat darker ocher-beige; SP abundant, white-yellowish with a slight green tint, oac014. No hypha clamps have been observed. All observed traits fit well to expectations for Irpex lacteus except cystidia. The fact that I haven't found conspicuously encrusted cystidia puzzles me.Spores smooth. Dimensions: 5.1 [5.9 ; 6.2] 7.1 x 2.5 [2.8 ; 2.9] 3.2 microns, Q = 1.9 [2.1 ; 2.2] 2.4; N = 47; C = 95%; Me = 6.1 x 2.8 microns; Qe = 2.2. Basidia dimensions approximately 20 x 4.5 microns.Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, in water (spores) and NEA 40x/0.65, magnification 400x, in water, congo red (hymenium, cystidia).
