5 μm wide. Perithecia (150–)180–240(–260) × (105–)130–200(–230) μm (n = 30), crowded, globose, ellipsoidal or flask-shaped; peridium (11–)14–20(–23) μm (n = 30) thick at the base, (6–)10–16(–20) μm (n = 30)

thick at the sides, yellow, when mature in KOH orange-red, particularly at the sides. Cortical layer (9–)11–23(–30) μm (n = 30) thick, a thin, dense, yellow t. angularis of minute, partly compressed cells (2–)3–7(–9) × (2–)3–5(–6) μm (n = 60) in face view and in vertical section, orange in 3% KOH. Subcortical tissue of thin-walled, hyaline or yellowish hyphae (2.5–)3.0–5.0(–7.0) μm (n = 30) wide, partly appearing https://www.selleckchem.com/products/OSI-906.html as angular cells (3–)4–8(–12) × 3–6 μm (n = 30) due to variable orientation. Subperithecial tissue a hyaline t. angularis–epidermoidea of thin-walled cells 6–25(–44) × (3.5–)5–14(–20)

μm (n = 35), becoming smaller and yellowish towards the base and mixed with thick-walled yellow hyphae (2.5–)3.5–7.0(–9.5) μm (n = 30); in attachment areas exclusively pseudoparenchymatous of cells 3–15 μm diam. Asci (62–)75–90(–101) × (4.3–)4.5–5.5(–6.5) this website μm, stipe (1–)5–13(–20) μm (n = 80) long. Ascospores hyaline, yellow when old, verruculose, cells dimorphic; distal cell (3.3–)3.7–4.5(–5.5) × (2.8–)3.5–4.0(–4.2) μm, l/w (0.9–)1.0–1.2(–1.4) (n = 90), (sub)globose or ellipsoidal; proximal cell (3.8–)4.3–5.8(–7.4) × (2.5–)3.0–3.3(–3.5) μm, l/w (1.2–)1.4–1.9(–2.4) (n = 90), oblong or wedge-shaped, often longer in the ascus base. Cultures and anamorph: optimal growth at 25–30°C on all media; slow and often limited growth at 35°C. On CMD after 72 h 10–12 mm at 15°C, 32–34 mm at 25°C, 34–37, 1–5 mm at 35°C; mycelium covering the plate after 6–7 days at 25°C.

Colony hyaline, thin, circular, dense, with indistinct light/dense and darker/looser concentric zones; denser zones slightly narrower. Hyphae curved, secondary hyphae narrow, sinuous, in steep nearly angles in growth direction; little mycelium on the agar surface. Aerial hyphae scant, short. Autolytic activity lacking or inconspicuous, no coilings seen. No diffusing pigment, no distinct odour noted. Chlamydospores noted after 4–7 days, uncommon, terminal and intercalary, (6–)8–13(–16) × (6–)7–10(–11) μm, l/w 0.9–1.5(–2) (n = 30), globose, oblong, ellipsoidal or clavate. Conidiation at 25°C starting after 3–4 days, not becoming green within 2 weeks; effuse, on mostly short, simple conidiophores concentrated in the centre and in lighter concentric zones, longer in distal areas; sometimes also in minute loose shrubs formed on locally aggregated hyphae; some conidiation also submerged in the agar. Short simple conidiophores 1–2 celled, with phialides solitary or in a terminal whorl of 2–3; longer ones of a main axis with few MK-8776 unpaired side branches; side branches with short, 1–2 celled, unpaired or paired terminal branches. Shrubs broad, to ca 0.
