Description type: Original description Basidiomata light rosy, pinkish, effused, closely adnate, confluent, hymenium surface pruinose under lens, smooth, first as a thin layer of pink powder on wood, then more distinct and visible, ceraceous, 80-100 µm thick, margin thinning out. Hyphal system monomitic, all hyphae simple septate, smooth, CB-, IKI-, not changed in KOH. Hyphae in subhymenium thin-walled, shortcelled, cells 6-10 µm long, 4-5.5 µm wide, hyphae in trama 2.7-4 µm wide, thin-walled, more or less intricate, densely united and difficult to discern, moderately branched towards hymenium, bearing basidia-supporting hyphae. Basal hyphae 4-5 µm wide, frequently branched at right angles and septate at branching point, walls slightly thickened. Basidia long clavate, flexuose, (40)50-75—(5)6.5-8 µm, thin-walled, with moderate percurrent proliferation, developing from roundish to bladder-like probasidia on vertically branching hyphae, bearing four stout sterigmata 5.5-7— 1.2-2 µm, rarely with only two sterigmata, without clamps, contents with dense granules, old basidia rarely provided with one or two transverse septa. Cystidia none. Few hyphidia are occasionally seen among basidia, 18-30—2.7-3 µm. Spores broadly ellipsoid to fusoid, often flattened adaxially, (10)11.5-14(18.5)—5.2-6.6(7.5) µm, Q=1.9-2.5, logV=2.15-2.74 (µm3), with a prominent truncate apiculus, contents densely filled with small granules, walls moderately thickened, smooth, CB+, IKI-, occasionally germinating from apiculus or from lateral wall. Paratype Iran, East Azerbaijan Province, Jolfa, Livarjan, on skin of thin hardwood branch mixed with debris on the ground, 12.V.2008, Ghobad-Nejhad 1406 (Ghobad-Nejhad ref. herb.). Habitat and Distribution Found among heaps of woody debris in orchard with old Juglans regia stands and cultivated Prunus armeniaca, Prunus cerasus, and Prunus domestica. At present, known only from Iran.
