Armillaria aotearoa

Ciri dan struktur

Armillaria aotearoa produces fruiting bodies (basidiomata) that grow in clusters (caespitose), with centrally positioned stalks supporting the caps. The cap, or pileus, measures between 35 and 60 mm across and is pinkish-brown to brown. The surface is dry and moderately smooth, scattered with small, dark granular scales that are more concentrated toward the centre. Initially convex, the cap flattens over time but retains a distinctive broad zone at the edges that darkens when it absorbs moisture (hygrophanous) but does not become sticky. The flesh of the cap is off-white to pale pink. The gills are attached near the top of the stalk (adnexed), moderately packed, and pale pink in colour. The stalk, or stipe, ranges from 35 to 90 mm in length, with a bulbous base and pale pinkish-brown colour that may show faint green or yellowish tones. It is dry, with tiny, scattered fibrils, and eventually hollows out as it matures. The flesh of the stipe is also off-white to pale pink. A partial veil forms a ring (annulus) around the stalk, with the underside matching the colour of the stipe and featuring concentrically arranged darker flecks. Armillaria aotearoa has rhizomorphs—root-like structures typical of the genus—that are black and show uneven branching. Microscopic examination reveals that the tissue within the gills (gill trama) is composed of thick-walled, inflated hyphae arranged in layers, with no clamp connections observed. The basidia (spore-producing cells) are club-shaped, bearing four spores each, and measure 31–49 by 5–9.5 μm. The spores are smooth, thin- to moderately thick-walled, ellipsoid to ovoid, and range from 7.5 to 10.5 μm in length and 5 to 7.5 μm in width; they are non-amyloid, meaning they do not stain with iodine, and appear transparent (hyaline) under a microscope.
