Data Set Maintenance: Data set standard item. Data set author(s): Rambold G. Data set reviewer(s): Döring H. (95-06-02, 00-02-07, 00-02-21); revised; to be published after submission.

Nomenclature: Current taxonomic status: accepted or basionymous. Taxonomic rank: genus. Number of known taxa within this rank: 1. Austropeltum. Sphaerophoraceae Fr. (1831); family of unknown placement (incertae sedis); Lecanorales.

Taxonomic Literature: Taxonomic notes: The type of boundary tissue present in the ascomata of Austropeltum,
Neophyllis and the mazaediate genera Bunodophoron, Leifidium and
Sphaerophorus is suggested as a synapomorphy of the family
Sphaerophoraceae. Henssen A., Döring H. & Kantvilas G., Bot. Acta 105: 457-467
(1992); Wedin M. & Döring H., Mycol. Res. 103: 1131-1137

Lichen Photobionts: Primary photobiont present; chlorococcal. Secondary photobiont absent.

Thallus: Crustose or foliose (peltate to umbilicate), not subdivided parts, squamulose, placodioid, or rimose, peltate, umbilicate (peltate to umbilicate). Thallus Outline: Soon disappearing. Upper Surface: Black, brown, or olive; special structures absent. Lower Surface: Attached by holdfasts; special structures present:; not pseudocyphellate; not cyphellate; not rhizinate; without thalloconidia thalloconidia; not cavernulate; tomentose.

Reproduction Strategy: Only known as sterile, asexually reproducing form or with sexual (and possible asexual) stages. Ascocarps: Apothecioid, orbicular or irregular, forming directly at the thallus margin, soon sessile to substipitate (usually a short pseudopodetial stipe is formed). Margin: Indistinct; external filaments absent. Periphyses: Absent. Epithecium: Apical cells black, grey, or brown. Interascal Hyphae: Present, scarcely branched, not or scarcely anastomosed. Hypothecium: Black or brown.

Ascospores: c. 8 per ascus, fusiform, (9)-11-16 µm long, 3-4.5 µm wide; septa absent; wall thin, not thickened at the septum, hyaline, in Lugol's Solution negative, wall not ornamented.

Conidiomata: Absent resp. not observed or present; pycnidial; immersed or stipitate, formed along the thallus periphery.

Conidiogeneous Cells: Apical or intercalar. Conidia: Filiform or curved; not branched; aseptate.
