| Sumario: | Systematics of the recently proposed Geastrum sect. Schmidelia are addressed through statistical analyses of quantitative morphological variables and phylogenetic reconstructions based on a multilocus approach. Emphasis is given to the taxonomic placement of G. schmidelii var. parvisporum. This variety is found to be not phylogenetically close to G. schmidelii var. schmidelii, the type species of G. sect. Schmidelia, and it therefore is excluded from this section, taxonomically raised to species rank (as G. parvisporum) and included as a member of G. sect. Hariotia. A second species in G. sect. Schmidelia is recognized and formally described as G. senoretiae. It is characterized by small basidiomata, non-hygrometric exoperidium, subsessile endoperidium and finely plicate, indistinctly delimited peristome, so far known only from Spain. Photographs and drawings are included, along with a comparison of morphologically close taxa. The presence of sclerified basidia in the mature gleba, previously not reported in the genus, is commented on |
