Perithecia (105–)130–190(–215) × (87–)110–160(–180)
Selleckchem OICR-9429 μm (n = 30), globose to flask-shaped, crowded, often lacking in marginal areas of the stroma; peridium (11–)13–19(–24) μm (n = 30) thick at the base, (6–)10–15(–19) μm (n = 30) at the sides. Cortical layer (13–)17–28(–34) μm (n = 30) thick, a narrow reddish brown t. angularis of indistinct, thick-walled, angular cells (2.5–)4.0–7.0(–8.5) × (2.0–)3.0–5.0(–6.5) μm (n = 67) in face view and in vertical section; surface smooth or with protuberances, mottled, i.e. pigment inhomogeneously distributed, appearing as resinous drops. Hairs on mature stromata (6–)8–22(–33) × (2.5–)3–5(–7) μm (n = 32), frequent, sometimes fasciculate, erect, cylindrical or attenuated terminally, 1–6 celled, pale brown, smooth or with minute globose warts. Subcortical tissue a (sub-)hyaline t. angularis of thin-walled cells (4–)5–11(–15) × (2.5–)4–7(–8) μm (n = 30) intermingled with some hyphae (1.5–)3.0–6.0(–7.5) μm (n = 30) wide. Subperithecial tissue a typically narrow
t. angularis–epidermoidea of variable thin-walled cells (4.5–)5–14(–22) × (2.5–)4–7(–9) μm (n = 30), hyaline or with yellowish brown patches. Basal and marginal tissue a t. intricata of hyaline to pale yellowish brown, thin-walled hyphae (1.5–)2–6(–10) μm (n = 30) wide, often incorporating algal cells. selleck products Thickness of subperithecial and basal tissues smaller than or equal to perithecial height. Asci (63–)70–90(–114) × (4–)5–6(–7) μm, stipe (1–)6–17(–30) check details μm (n = 45) long; croziers apparently absent. Ascospores hyaline, verruculose or finely spinulose, often smooth inside asci, cells dimorphic, distal cell (3.3–)3.5–4.2(–4.7) × (3.0–)3.5–4.0(–4.7) μm, l/w 1.0–1.1(–1.2) (n = 60), (sub-)globose, sometimes wedge-shaped, proximal cell (3.3–)4.0–5.0(–6.3) × (2.3–)2.8–3.5(–4.0) μm, l/w (1.2–)1.3–1.6(–1.8) (n = 60), oblong, wedge-shaped, or subglobose. Cultures and anamorph: www.selleckchem.com/products/AZD8931.html optimal growth at 25°C on all media, poor
and limited growth at 30°C, no growth at 35°C. On CMD after 72 h 15–18 mm at 15°C, 26–28 mm at 25°C, 4–6 mm at 30°C; mycelium covering the plate after 1 week at 25°C. Colony hyaline, thin, circular; hyphae with irregular orientation. Margin well-defined, appearing curly due to numerous large coilings and numerous minute secondary hyphae. Aerial hyphae infrequent, becoming fertile; more abundant and longer in distal areas and there often visible as white radial patches. No autolytic activity noted, but minute excretions frequent at 30°C. Coilings characteristic, conspicuous, particularly in marginal areas of the colony, large, 150–500 μm diam. No pigment, no distinct odour noticeable. Chlamydospores rare, noted after 1–2 weeks, abundant at 30°C.
