Terfezia fanfani Mattir., Malpighia 14: 65 (1900)

Lectotype (iconotype, here designated MBT382512 ): Mattirolo, Malpighia 14, pl. I f. 28–32 (reproduced here as Fig. 1a View FIGURE 1 )

Epitype (here designated MBT382513): Spain, Cáceres, Valdecañas, acidic grassland with Tuberaria guttata ( Fig. 2b View FIGURE 2 ), 14 April 2001, Muñoz-Mohedano (MUB Fung-0004), (ITS sequence GenBank acc. number: HM056217). ( Figs. 1b View FIGURE 1 – 2a View FIGURE 2 ).

Description:― Ascomata globose, round, regular, occasionally lobed, usually with mycelial remnants, 2–5 cm diam., smooth or slightly rough; firm; usually odourless. Peridium smooth, slightly rough, inseparable from the gleba, 200–700(–2000) μm thick; initially white, soon becoming reddish brown, darkening in maturity with black maculae present in sun-exposed zones exposed; white in cross-section; pseudo-parenchymatous structure formed by rounded prismatic cells ( Fig. 1f View FIGURE 1 ). Gleba initially white, then fertile tissue in islets becoming pale pink, then olive green, finally blackish grey when very mature. The gleba is always surrounded by white sterile tissue. Asci primarily 8-spored, sessile; subglobose, elongated and ovoid, 70–80 × 55–70 μm with 1 μm thick walls. Ascospores spherical with spines, 14–17(–18) μm (on average = 15.5 μm, measured without ornamentation), initially hyaline, smooth, with a large central drop; in age ochre yellow and decorated with sharp thin elongated conic spines (2–)3–4(–5) μm long with 1 μm diam. bases (the spines not joined through the bases). ( Fig. 1c–e View FIGURE 1 ).

Habitat acidic grasslands associated with Tuberaria guttata from March to May ( Fig. 2b View FIGURE 2 ).
