Solenopezia [ Solenopeziza] tetraspora Henn., in Engler, Pflanzenw. Ost-Afrikas Nachbarg., Teil C: 30. 1895. Typus: Tanzania, on thallus of Physcia integrata Nyl., unknown collection date, Holst n. 795 ( type not located).

Ascomata perithecioid, superficial, globose to subglobose, yellow to orange,collapsed when dry,with tiny subiculum on the lower part of ascomata, covered by abundant septate hyaline hairs, 150–250 μm diam. Ascomatal wall formed by several layers of cells, yellowish externally, up to 20 μm thick, inner hyaline, 10–12 μm, KOH–. Asci unitunicate, subcylindrical, 4-spored, 70–80 × 7–10 μm (n = 20). Ascospores hyaline, 1-septate, ellipsoid, with pointed and sometimes apiculate ends, slightly constricted at the septa, smooth-walled, without perisporium, (16.8–)19.4–24.4(–26.6) × (5.9–)6.2–7.5(–8.4) μm (n = 50). Conidiomata not observed.

Distribution, habitat and host range: This species is known from numerous localities from South America and Africa ( Tanzania), growing on several species of Heterodermia s. lat. ( Etayo 2002, 2017). However, the record from Tanzania needs revision as we were not able to locate the specimen in the collection of P.C. Hennings stored at B.

Notes: Etayo (2002) discussed the morphological similarity of the ascomata of Sphaeronectria lichenophila to the genus Paranectria and pointed out the differences between this species and other fungi of Nectriopsis . These differences are supported by resulting phylogenetic analyses which showed a close relationship between Sphaeronectria and Paranectria rather than Nectriopsis .
