Protocrea pallida  

Anamorph: present in most specimens on the margin of the stroma, around perithecia or in separate patches. Conidiophores to ca 160 µm long, 5.0–6.5 µm diam. at the base, 4–4.5 µm below the primary branch; terverticillate, branches 2.0–2.5 µm diam., terminating in dense whorls of ± parallel conidiogenous cells. Conidial heads white (rarely yellow to orange), 30–60 µm diam. Conidiogenous cells (5–) 8–13 (–16) x (1.5–) 2–2.5 (–3) µm, narrowly lageniform to subulate, straight or basally curved, proliferating percurrently. Conidia (2.5–) 2.8–4 (–11) x (1.2–) 1.5–2.2 (–3) µm, mostly ellipsoidal to cylindric-ellipsoidal or clavate, aseptate, hyaline, smooth, thin-walled, without an epispore or gelatinous sheath.
Teleomorph: Ascoma perithecial, collapsed cupulate when dry, in large numbers and closely aggregated on a pale effuse subicular stroma, slightly (to ca one-third) projecting, rarely free, yellow to orange when fresh, bright orange to yellow or brownish when dry; ostioles inconspicuous, papillate, the apex rounded or ± conical. Subiculum reddish to pink in KOH.  Perithecia (150–) 190–250 µm high, (125–) 150–200 (–225) µm diam., globose to pyriform, the ostiole periphysate. Peridium composed of hyaline refractive elongate thick-walled compressed cells inside, more isodiametric outside, partly covered by hyphae. Interascal tissue not seen. Asci (60–)70–86 (–98) x (3.0–) 3.7–4.3 (–5.0) mm, the stipe (2–) 6–20 (–33) µm long, cylindrical, the apex obtuse to truncate, thickened to 1.0–1.5 µm, with a minute pore and a flat ring below. Ascospores hyaline, verruculose when young and ± smooth when mature, 1-septate, separating at the septum, the cells dimorphic, distal cell (2.7–) 3.0–3.7 (–4.3) x (2.4–) 2.7–3.2 (–4.0) mm, subglobose to ellipsoidal (to nearly wedge-shaped), proximal cell (3.0–) 3.5–4.3 (–5.7) x (2.0–) 2.4–3.0 (–3.5) mm, broadly cylindric-ellipsoidal to broadly wedge-shaped.
