Phialides (n = 180) lageniform, straight or less frequently hooke

Phialides (n = 180) lageniform, straight or less frequently hooked, asymmetric or sinuous, (3.5–)6.2–10.5(−15.7) μm long, (2.0–)2.5–3.7(−4.5) μm at the widest point, L/W = (1.3–)1.6–3.8(−7.7), base (1.0–)1.7–2.7(−3.5) μm wide, arising from a cell (1.5–)2.5–4.0(−5.5) μm wide. Conidia (n = 180) oblong to ellipsoidal, (3.2–)3.7–6.2(−10.5) × (2.0–)2.5–3.5(−5.2) μm. L/W = (1.1–)1.3–2.5(−4.9) (95% ci: 4.9–5.2 × 2.8–3.0 μm, L/W 1.8–2.0), green, smooth. Chlamydospores typically forming on SNA, terminal and intercalary, subglobose to clavate, (4.5–)6.2–9.0(−14.0) μm diam. Teleomorph: Stromata

scattered or aggregated in small groups of 2–4, when fresh ca. 1–4 mm diam, linear Selleck PF-6463922 aggregates up to 8 mm long, up to 1.5 mm thick; pulvinate or discoid to undulate, surface glabrous or slightly velutinous, grayish olive when immature, light brown or orange-brown to dull dark brown with olive tones, with nearly black ostiolar dots. Stromata when dry (1.0–)1.2–2.5(−3.2) × (1.0–)1.2–2.0(−2.7) mm, 0.2–0.7(−1.0) mm high (n = 20), discoid with concave top, or pulvinate, with circular, oblong or irregularly lobate outline, often margin free to a large extent (narrow attachment); starting as a yellow learn more compacted mycelium, immature distinctly velutinous, light olive with a yellowish tone, later olive-brown, less commonly orange-brown, with delicate, more or less stellate fissures 45–110 μm

long, later with distinct, even or convex black ostiolar dots (39–)48–78(−102) μm diam (n = 30), often surrounded by torn, crumbly cortex; when old collapsing

to thin, rugose, dark (olive-) brown crusts. Spore deposits Nintedanib (BIBF 1120) whitish. Ostioles apically green in lactic acid. Asci cylindrical, (74–)78–89(−93) × (5.2–)5.8–6.7(−7.0) μm, apex truncate, with an inconspicuous apical ring. Part-ascospores monomorphic, globose or subglobose; distal cell (3.2–)3.7–4.5(−4.7) × (3.5–)3.7–4.2(−4.7) μm, l/w (0.9–)1.0–1.1(−1.2) (n = 30), proximal cell (3.7–)4.0–4.7(−5.0) × (3.5–)3.7–4.5(−4.7) μm, l/w 1.0–1.2(−1.3) (n = 30), ascospore basal in the ascus typically laterally compressed, dimorphic; verrucose with warts ca. 0.5 μm long. Known distribution: Europe (Germany), Canary Islands (La Palma), China, East Africa (Sierra Leone, Zambia), South Africa, Central America (Costa Rica), South America (Brazil, Ecuador, Peru). Teleomorph confirmed only from China and the Canary Islands. Habitat: wood and fungi growing on it (teleomorph), soil. The above description of the teleomorph is based on the following collection: Spain, Canarias, La Palma, Cumbre Nueva, Castanea plantation at the road LP 301, close to crossing with LP 3; on dead branches 2–10 cm thick of Castanea sativa, on wood, soc. this website Jaklitsch S187 (WU 31609; culture CBS 131488).
