Calopadia cinereopruinosa
liquen punto de hojas, Leaf dot lichen
Thallus corticolous or between bryophytes, continuous or marginally dispersed into rounded, confluent patches, up to 30 mm across and 20–40 μm thick, ecorticate or with an indistinct cortical layer, smooth, pale grey to greenish grey. Apothecia rounded, 0.4–1 mm diameter and 250–350 μm high; disc plane, grey-black and with distinct, white pruina; margin distinct, rather thick and prominent when young, grey-black and white-pruinose. Excipulum 50–70 μm broad. Hypothecium 50–100 μm high, aeruginous. Apothecial base aeruginous. Epithecium 5–10 μm high, granular, grey-brown. Hymenium 120–190 μm high, colourless. Asci 100–170 × 20–30 μm. Ascospores single, oblong-ellipsoid, muriform, 45–80 × 15–25 μm, 3–3.5 times as long as broad, colourless. Campylidia sessile, 0.4–0.7 mm broad; lobe well-developed, hood-shaped, grey but white-pruinose; socle not apparent. Conidia filiform with clavate apex, 3–7-septate, 40–55 × 1–1.5 μm.
Calopadia cinereopruinosa closely resembles C. subcoerulescens (Zahlbr.) Vĕzda in the grey-black apothecia and aeruginous hypothecium. However, the apothecia are thickly and persistently pruinose, a feature not observed in C. subcoerulescens. The new species is similar to C. editae, in forming pruinose apothecia and ascospores shorter than 100 μm, but C. editae has brownish apothecia often with a yellowish tinge and the hypothecium is light brown. The two paratype specimens bear campylidia only and their identification is not absolutely certain, however, the pruinose lobes indicate that they belong to the new species, as other species in the genus with non-pruinose apothecia also have non-pruinose campylidia.
