Stromata when dry (0.5–)1.0–2.3(–3.0) × (0.5–)0.8–1.8(–2.2) mm, (0.3–)0.4–1.0(–1.4) buy IWP-2 mm thick (n = 30); solitary, gregarious or aggregated in small numbers, pulvinate or semiglobose, broadly attached, margin rounded, angular or undulate, often free, with a white mycelial base margin when young or sometimes fertile yellow part laterally selleck products projecting over a whitish, stipe-like base or stromata arising from and lifted above a thick whitish mat containing the anamorph. Ostiolar dots (39–)50–100(–140) μm (n = 33) diam, plane, circular, brown with lighter centres, first diffuse, becoming distinct.

Stroma colour from yellow, 4AB4–6, over yellow-brown, 5CD5–8, to brown-orange or brown, 6–7CD7–8, 7E6–8. Spore deposits white or yellowish. Rehydrated stromata larger by 30–40%, reddish brown to the unaided eye, yellow to orange in the stereo-microscope, with papillate, orange-brown dots; after addition of 3% KOH instantly orange-red, macroscopically dark red. Stroma anatomy: Ostioles (67–)74–100(–128) μm long, plane or projecting to 20 μm, (15–)20–35(–50) μm wide at the apex inside (n = 30), cylindrical, with or without clavate marginal cells 3–5 μm wide at the apex. Staurosporine Perithecia (180–)225–300(–325) × (100–)130–230(–290) μm (n = 30), globose

or flask-shaped; peridium (15–)18–27(–33) μm (n = 30) thick at the base, (6–)12–22(–24) μm (n = 30) thick at the sides, pale yellowish, in KOH pale orange. Cortical layer (20–)25–37(–46) μm (n = 30) thick, a dense t. angularis of distinct, thin- to thick-walled cells (3–)5–10(–12) × (2.5–)4–7(–11) μm (n = 63) in face view and in vertical section, yellow, gradually paler downwards, in KOH orange, on stroma sides paler to hyaline and intermingled with hyaline hyphae (2–)3–6(–7) μm (n = 30) wide in lower parts. Hair-like projections

on mature stromata (4–)5–12(–17) × (2–)3–5(–6.5) μm (n = 30), 1–3 celled, hyaline or yellowish, mostly cylindrical, often with thickened base, smooth or verruculose. Subcortical tissue a loose t. intricata of hyaline thin-walled hyphae (2–)3–5(–6) μm (n = 30) wide. Subperithecial tissue a t. angularis–epidermoidea–prismatica of hyaline, mostly oblong, thin-walled cells (7–)10–30(–58) × (4.5–)6–11(–14) μm (n = 30). Asci (98–)110–130(–140) × (4.8–)5.3–6.5(–7.0) μm, PAK5 stipe (13–)23–40(–50) μm (n = 30). Ascospores hyaline, sometimes yellow, even inside asci, verruculose; cells dimorphic, distal cell (3.5–)4.0–5.3(–5.7) × (3.2–)3.5–4.0(–4.5) μm, l/w (0.9–)1.1–1.4(–1.7) (n = 32), (sub)globose or wedge-shaped, proximal cell (3.8–)5.0–6.5(–7.5) × (2.8–)3.2–3.8(–4.0) μm, l/w (1.1–)1.4–1.9(–2.2) (n = 32), oblong or wedge-shaped; contact area often flattened. Anamorph on the natural substrate forming white cottony tufts, e.g. 1.5 × 1 mm, associated with stromata, with short, straight to helical elongations. Right-angled branching common.
