Slo.: irokolistna velekorenovka - syn.: Collybia platyphylla (Pers.) P. Kumm., Clitocybula platyphylla (Pers.) E. Ludw., Oudemansiella platyphylla (Pers.) Moser, Tricholomopsis platyphya and many others - Habitat: mixed wood, Fagus sylvatica and Picea abies dominant trees with some Ostrya carpinifolia and Fraxinus ornus; slightly inclined mountain slope, SE aspect; old colluvial, calcareous ground, in shade, dry and relatively warm place; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.950), alpine phytogeographical region.Substratum: heavily rotten, moss covered stump of Fagus sylvatica. Comments: When I noticed this fungus I thought it was a kind of Pluteus (actually Pluteus cervinus (Schaeff.) P. Kumm. looks very similar). However, neither its spore print nor gills showed even a trace of pinkish color. So, it must be almost for sure Megacollybia platyphylla. Its streaked-looking gray-brown cap is typical.Genus Megacollybia was considered monophyletic (that is containing only one specie - Megacollybia platyphylla) not so far ago. Recent DNA sequencing in North America (Ref.3) showed that it can be separated to several distinct species (how many of them scientists do not agree, up to nine worldwide). One of them Megacollybia platyphylla was limited to Europe. Unfortunately newly recognized species in North America cannot practically be separated by macro-morphological traits (particularly not if geographic location is dismissed as a 'character'). They are all variable and all look alike. Even microscopy doesn't help. To determine them in the field one would need 'pocket DNA sequencer' (which doesn't exist). So it is: DNA-defined species do not always show observable differences in physical features. Megacollybia platyphylla is a common mushroom. There are conflicting reports about edibility of it. Some consider it conditionally edible, some weakly poisonous. Description of this find: Growing solitary; heavily eaten by snails; pileus diameter 13 cm, radially streaked, strakes peel off easily; trama thin, gills broad, beige, fragile; stipe 8 cm long, 23 mm in diameter at the base and 19 mm on top, firm, slightly hollow at the center, fibrous, firmly attached to the rotten wood by mycelial strands; smell slightly on sour bread, taste mild, indistinctive; SP faint, beige, oac814.Spores smooth. Dimensions: 7.3 [8 ; 8.3] 9 x 5.9 [6.5 ; 6.8] 7.4 microns; Q = 1.1 [1.2] 1.4; N = 30; C = 95%; Me = 8.1 x 6.7 microns; Qe = 1.2.

Moser - Habitat: grassland; semiruderal, flat terrain near a village house; calcareous ground, shallow soil layer; nitrogen rich place (my dog's favorite place to pee); open, fairly sunny place; mowed several times per year; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region.Substratum: soil.Comments: Bolbitius titubans is generally a common mushroom but apparently not in the Upper Soa River region. The place of this observation is almost in front of my house, where I live. I know this piece of grassland for decades. Yet, I have seen this mushrooms only once - in 2013. There were several dozens of them appearing again and again starting at the beginning of October until the end of November. Pilei are ephemeral and of similar habitus as in genus Coprinus but vividly lemon to yolk yellow, beautiful particularly when they are young. It is impossible to overlook them in low grass. They are viscid and very delicate. Growing solitary and in groups of a few fruit bodies; flesh very brittle; SP brown with reddish tint; smell and taste indistinctive.Spores smooth with thick walls and large germ pore.
