Observation 185801: Cortinarius meinhardii Bon
When: 2014-09-12
(46.3633° 13.7491° 1020m)

Notes: Code: Bot_836/2014_DSC4043

Habitat: steep northwest oriented mountain slope, mixed wood, Fagus sylvatica and Picea abies dominant trees, in shade, quite humid place, calcareous ground, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 1.020 m (3.350 feet), alpine phytogeographical region.

Substratum: soil, among fallen leaves and needles.

Place: Lower Trenta valley, just below Planina Lepoč where the trail from Trenta village flattens, East Julian Alps, Posočje, Slovenia EC.

Comments: Contrary to several authors Kriegelsteiner (Ref.: 2) distinguishes Cortinarius splendens from Cortinarius meinhardii and grounds this position on molecular studies made by Garnica. He describes almost no morphological difference between both. Dimensions, shapes, colors, type of ground and spores of both species are almost the same, smell and habitat being exceptions. C. meinhardii should be mycorrhizal partner with conifers (mostly Picea abies), should climb up to upper montane elevations and should have distinct smell on blackpepper. On the other hand, C. splendens should grow at lower elevations, mostly in planes, should be associated with broadleaved trees (mostly Fagus sylvatica) and should have no distinctive smell. The mushrooms photographed grow in mixed mountain wood, Picea abies and Fagus sylvatica being dominant; they were found in montane elevations and have mild, pleasant smell, definitely not on black pepper. So, there was little ground to decide for one or another options. Fortunately (at least for me), it was not necessary. Index Fungorum keeps both names as synonyms taking C. meinhardii as currently valid name.

Growing in a small group of three sporocarps. Pilei diameter 4.5-6.5 cm, cuticle sticky, stipe 4-7 cm tall, 1.3 cm in diameter, bulb up to 3 cm in diameter; SP abundant, brown-orange, oac713.
