Description

*Caracters observed in living material.

Ascomata semihypogeous, initially globose to pyfiform, with a central opening that becomes broader, with the margin progressively split into lobes of unequal size, acquiring a star-like appearence, fragile, 5-8 cm diam. and 3-7 cm high. Hymenium smooth, vinaceous red. Outside concolorous, smooth or wrinkled due to small, sometimes subestipitate bumpings. Context slightly lighter than the outside, not producing milky exudates.

Ascospores ellipsoid, thick-walled, multiguttulate with small, grouped, pale yellow guttules*, with very small warts visible as small dots in lactic CB, hard to observe in immature spores, (14.7-)15.4-17.6(-18.7) × (9.4-)10.38-11.9(12.1) µm (Lm = 16.6, Wm = 11.1; Q = (1.3-)1.42-1.61(-1.7); Qm = 1.5; N = 52)*. Asci cylíndrical, slightly curved, operculate, 8-spored, pleurorhyncous, with very pale yellow guttulate content*, diffusely amyloid in the apex and lateral walls, 254-353(-392.5) × 13-15.6 µm (Q = 17.1-25.3; N = 11). Paraphyses cylindrical to slightly broader towards the apex, 4.3-6.5 µm broad, septate, moniliform due to having constricted septa, especially towards the apex, often forked on the lower half. Medullary and ectal excipulum not clearly delimited, with a pale brown pigment;  medullary excipulum more or less of a textura prismatica, composed of parallel-arranged hyphae, interwoven with subglobose cells, of (14.7-)19.6-39.5(-43.5) × (10.3-)13.52-23(-32.7) µm; ectal excipulum more or less of textura angularis type, composed of angulose cells, of similar size as the ones from the medullary excipulum. Subhymenium poorly differentiated from the rest of the excipulum.

Habitat and distribution: Sarcopeziza sicula appears to be restricted to the central and east Mediterranean basin, as well as to south Spain. It is rare accross its known distribution area. The first find in Spain and the Iberian Peninsula is presented here. Sarcopeziza sicula fruits between January and April, solitary or forming small groups, developping its ascomata under ground and emerging when they mature. It occurs in sun-exposed areas or bare calcareous ground, with or without presence of trees, also close to the sea-shore, near Cistus and Pinus halepensis, or in plantations of olive trees (Olea europea) (Agnello et al. 2018).
