Stromata dark orange-brown to reddish brown, with lighter or white margin, 5–6EF6–8, 6–7CD7–8, 7–8E5–8. Stromata unchanged or orange-red in 3% KOH, with mottled pigment and minute hyaline ostiolar openings. Stroma anatomy: Ostioles (55–)65–86(–99) μm long, umbilicate or projecting to 20(–37) μm, (30–)37–61(–80) μm wide at the apex (n = 20); apical palisade of hyaline, narrowly clavate cells. Perithecia (175–)210–275(–300) × (105–)150–225(–270) μm (n = 20), globose or flask-shaped; peridium hyaline,

(7–)11–18(–20) μm (n = 40) thick at the base and sides. Cortical layer (20–)21–38(–47) μm (n = 20) thick, yellow-brown, mottled, i.e. with inhomogeneously distributed pigment, a t. angularis of thin-walled cells (3.5–)5–10(–13) × (3–)4–7(–9) μm (n = 60) in face view and in vertical section; present around the this website entire stroma except for the attachment area. Hairs (12–)13–28(–35) × (2.5–)3–5(–6) μm (n = 15), scant, short, 2–4 celled, verrucose, narrowly rounded apically. Subcortical tissue a loose t. intricata of hyaline, thin-walled hyphae (2.5–)3.5–6.0(–7.5) μm (n = 20) wide. Subperithecial tissue a narrow, dense, hyaline t. epidermoidea of thin-walled cells (5–)7–18(–26) × (3–)5–11(–14)

μm (n = 30), followed by a palisade of coarse, elongate, thick-walled, refractive cells (15–)16–29(–36) × (8–)10–15(–18) μm (n = 20), and a basal layer of hyphae (2.0–)2.8–5.2(–6.0) μm wide (n = 10), SCH772984 molecular weight intermingled with small-celled textura angularis, hyaline, partly brownish. Asci (74–)84–105(–116) × (4.7–)5.3–6.3(–7.0) μm, stipe 2–13(–16) μm long (n = 50), without croziers. Ascospores hyaline, distinctly verrucose or spinulose with tubercles to ca 0.7 μm long and wide; cells dimorphic, distal cell (2.8–)4.0–5.5(–6.6) × (2.7–)3.3–4.3(–5.2) μm, l/w 1.0–1.4(–2.2)

(n = 70), globose, subglobose or wedge-shaped, particularly in the ascus apex, proximal cell (3.7–)4.5–6.3(–7.5) × (2.8–)3.0–3.7(–4.7) μm, (1.1–)1.3–1.9(–2.4) (n = 70), Progesterone oblong, wedge-shaped or subglobose, contact area distinctly flattened before maturation. Anamorph on the natural substrate typically conspicuous, spreading over large areas or entire branches, thickly effuse, bright blue-green when fresh, when dry dull or grey-green 25E4–6, 26E3–4 to 26F5, with white margin when young. Cultures and anamorph: optimal growth at 25°C on all media, no growth at 35°C. On CMD after 72 h 12–16 mm at 15°C, 35–37 mm at 25°C, 28–34 mm at 30°C; mycelium covering the plate after 6–7 days at 25°C. Colony hyaline, thin, dense, not zonate. Autolytic excretions inconspicuous, frequent at 30°C, coilings and aerial hyphae inconspicuous. Reverse diffuse greenish yellow 1–3B3–4 after 1 week; after 2 weeks a weak coconut-like odour noticeable. Chlamydospores noted after 3–6 days, frequent in distal and lateral areas, intercalary and terminal, (sub-)globose, ellipsoidal to oblong.
