Melanoleuca subbrevipes Mtrod, Revue Mycol., Paris 7(2-4): 90 (1942), syn.: Melanoleuca grammopodia (Bull.) MurrillSlo.: iroka gostolistka, tenkobetna gostolistkaDate: Oct. 10. 2009Lat.: 46.30088 Long.: 13.41864Code: Bot_390/2009-6210Habitat: Steep mixed wood, predominantly Fagus sylvatica, north oriented, relatively cool place, in shade, protected from direct rain by tree canopies, locally flat calcareous ground covered with a thick layer of dead Fagus sylvatica leaves, average precipitations ~3.000 mm/year, average temperature 6-8 deg C, elevation 800 m (2.600 feet), alpine phytogeographical region.Substratum: forest soil covered with a thick layer of dead leaves. Place: North slopes of Mt. Kobariki Stol ridge, north of Mt. Gabrovec, 1,630 m (5.348 feet), East Julian Alps, Posoje, Slovenia ECComments: Growing in groups, circles, lines. Many specimens present. Flesh brittle and watery, hut surface shiny somewhat waxy, gills dense and narrow. All specimens shown are quite old. White tomentum visible on some mushrooms is another fungus or mould species attaching M. subbrevipes. Ref.:(1) Personal communication Mr. Anton Poler and Mr. Bojan Rot,

Melanoleuca subalpina, (Britz.) Bresinsky & Stangl., Melanoleuca evenosa ss. Konr., Melanoleuca strictipes ss. Khn, Tricholoma cnistass. Bres.EN: ?, DE: ?Slo.: tenkobetna gostolistka (assuming Melanoleuca strictipes and Melanoleuca alpina are synonyms) (Melanoleuca alpina is not listed in SI checklist)Dat.: Aug. 1. 2014Lat.: 46.44223 Long.: 13.63734Code: Bot_820/2014_DSC2416Habitat: east inclined moderately steep alpine grassland, calcareous ground, open place, full sun, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature about 0 deg C, elevation 2.030 m (6.600 feet), alpine phytogeographical region.Substratum: soil.Place: Mangart's flats, just below ez jezik pass, east of Mt. Skala, 2.133 m (6.996 feet), East Julian Alps, Posoje, Slovenia EC Comments: At least three names can be found in literature in connection with relatively large, more or less whitish Melanoleuca species growing at alpine elevations - Melanoleuca subalpina, Melanoleuca evenosa and Melanoleuca strictipes. Taxonomy of these taxa seems to me messy; to my knowledge no monograph dedicated to this genus is available. Some authors, including Index Fungorum, consider these names as separate species; some consider them as synonyms (for example Breitenbach (1991)). Ref.: 1. considers Melanoleuca subalpina and Melanoleuca evenosa synonyms and Melanoleuca strictipes a separate species. Ref.:3. considers Melanoleuca evenosa and Melanoleuca strictipes as synonyms. In literature data about spore dimensions also contradicts.The find shown corresponds excellently to the description of Melanoleuca subalpina given in Dhncke (2009), hence I decided for it. Since pilei diameters of this observation in average equal or exceed stipe length this should be Melanoleuca alpina and not Melanoleuca strictipes (ss. Ref.4) (assuming both are separate species). However measured spore dimensions of this find do not fit to data given in Dhncke (2009), but they fit well to Breitenbach (1991) and Bresinsky (1977) and also to other sources (assuming Melanoleuca strictipes and Melanoleuca subalpina are synonyms). More and more I value Arora's advise that '... exact identities of closely related Melanoleuca-s are best left to Melanoleuca-masters'.Growing in a group of about 10 pilei in an area of about 4 x 4 m; pileus diameter 6-8(16) cm, hygrophanous to some extent; stipe shorter or equal to pileus diameter (see Ref.3.); taste mild; smell mild but characteristic, may be slightly on vegetable or turnips?; flesh brittle and watery, fibrous in stipe, SP abundant, beige, oac851.Spores smooth.
