Pleurotus djamor (Fr.) Boedijn var. djamor
in De Wit, H.C.D., Ed., Rumphius Memorial Vol., p. 292, 1959.
Pileus white 25-40 x 23-40 mm, spathulate to flabelliform (figs. 5A, 11E), brown when dry; glabrous, smooth to touch; margin entire, frequently lobate and imbricate in old specimens. Context 0.5-6 mm thick, always less than 1 mm when dry. Lamellae white 2-4 mm broad, 1.5-1.75 mm in dry state, decurrent, crowded, smooth, margin entire. Stipe 5-6 mm long x 3-4 mm diam, lateral, smooth, rarely absent. Spore print white. Odor not distinct. Good edibilit
Spores (6.0-)6.7-7.2(-7.80) x 2.60-3.12 µm Q = 2.44, cylindrical-oblong, hyaline, not dextrinoid or amyloid, thin-walled. Basidia club-shaped 26-28 x 4-5.2 µm. Cheilocystidia mucronate 26-31 x 7-7.8 µm. Hymenophoral trama dimitic, with sharp-pointed skeletal hyphae 3-4.4 µm and clamped generative hyphae 3.1-6.24 µm diam (FIG. 5B). Pileipellis 100-160 µm broad with hyphae arranged parallel to the pileus but somewhat irregularly entangled. Context with generative hyphae 3.6-5.2 µm diam and skeletals 3-5.2 µm (fig. 5C). Stem context with narrower generatives, 2.6-3.1 µm diam and skeletals 3.1-5.2 µm diam (fig. 5D).
Culture characters. - Mycelium hyaline, filamentous, radial growth, well adhered to substrate. Margin irregular, undulate. Against the light, an unequal refraction was observed, causing a relief aspect. Odor not distinct. The mycelium did not cover the Petri plates in 6 wk. Pinkish zones were observed in some strains.
Advancing mycelium with hyaline, thin-walled, clamped, scantly branched 1.5-2.6 µm diam hyphae. In the middle of the colony with some contorted hyphae 1.5-4.2 µm diam. Near the inoculum with regularly branched hyphae 1.6-4.2 µm diam. Micro-droplets 2.5-5.2 µm diam not observed in dikaryotic mycelia, but present in monokaryotic mycelia.
Geographic distribution. - Northeastern Argentina.
