Lecania granulata  

Thallus: whitish to pale buff, densely granular-blastidiate, to 1.5 mm thick; granules 30–80(–100) µm diam. Photobiont chlorococcoid, cells 5–12 µm diam or ellipsoidal to 14 x 12 µm in size.

Anamorph: not known.

Teleomorph: ascomata apothecia, (200–)300–700 µm diam, flat or becoming convex and then up to 900 µm diam, each developing within a thalline wart and becoming urceolate with a crenulate thalline margin and concave disc, later expanding further with the thalline margin becoming granulate or receding to reveal a proper margin, and with the disc becoming plane to convex. Disc pale, pinkish or pallid, often with patchy brown pigment towards the margin in older apothecia, with paler proper margin. Thalline exciple ca 40–60 µm wide. Proper exciple lateral to hymenium 35–60 µm wide, but not clearly delimited from hypothecium below, hyaline or dilute reddish brown, in outer half composed of ± radiating hyphae with lumina to 5 x 2.5 µm, cortical cells ca 5–6 µm diam. Hymenium 50–65 µm tall, hyaline or tinged dilute reddish brown in part in older apothecia; epihymenium hyaline or with patchy dilute reddish brown pigment, especially towards the margin; subhymenium 20–35 µm tall, K+ dilute yellow, with cells of ascogenous hyphae to 5 µm diam. Hypothecium massive, of irregularly orientated, slender hyphae ca 10–17 µm wide. Interascal tissue of simple paraphyses, ca 1.5 µm diam in mid-hymenium, the upper 2–4 cells gradually widening to 4(–6) µm diam, ± lax in K. Asci 53–60 x 9–11 µm, narrowly clavate, Bacidia-type. Ascospores 20–33 x (2–)2.5–2.7 (–3) µm, narrowly clavate-fusiform to shortly acicular, 3–5(–7)-septate.
