location
Lower Trenta valley, between villages Soča and Trenta, left bank of river Soča, about 8 m off water stream, near the bridge to Matevž, Trenta 1 farmhouse, East Julian Alps (Posočje, Slovenia)notes Slo.: obročkani luskinček - syn.: Pholiota arrhenii (Fr.) S. Imai, Conocybe arrhenii (Fr.) Kits van Wav. - Habitat: river bank, frequently flooded terrain covered with organic river deposits; flat terrain, calcareous ground; moist and cold place, in half shade; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 528 m (1.730 feet), alpine phytogeographical region. - Substratum: moist humus soil and buried, almost completely disintegrated wood of (probably) Salix eleagnos. - Comments: IF and Mycobank disagree regarding the current name of this species. IF uses Conocybe arrhenii as current name while Mycobank uses Pholiotina arrhenii as the legitimate name. The spore dimensions are a bit too wide and better fit to Pholiotina rugosa. Hence the determination may be questionable. On the other side habit (particularly the ring, which is whitish and placed mid-height) fits better to Pholiotina arrhenii. - Pilei diameter from 1.7 to 2.8 cm; stem thin, firm, elastic, hollow, 3.5 to 4.5 mm in diameter at the base somewhat thicker; smell indistinctive; spore print abundant, rusty–reddish-brown, oac762. Spores smooth or eventually minutely warty. Dimensions: (7.6)7.8 - 8.9(9.4) × (4.5)5.2 - 5.9(6.1) µm; Q = (1.4)1.43 - 1.6(1.8); N = 35; Me = 8.4 × 5.5 µm; Qe = 1.5.
