......................................................................................................................................................... 2
1?. Ascospores disarticulating into numerous part-spores within the ascus; Peyronelia anamorph present.
......................................................................................................................................................... 3
2. Ascomata 1–3 mm high, 0.2–0.3 mm wide; ascospores 200–415 (650) × (1–) 2 (–3) ?m, nearly as long as the

parallel, multiseptate, with septa 4–5 ?m apart; on Tillandsia, Florida.

3. Asci (310–)460–550(–700) × (7–) 8–10 ?m; ascospores similar in length, multiseptate, +/? spiralling for part of
their length, part-spores cylindrical truncate, pale brown (1–)–3– (–7) septate (8–)14–20(–37) × (1.5–) –2– (–3) ?m;
conidia multiseptate, usually with one or two longitudinal septa, branched and with lateral buds, forming chains up
to 230 × 10–17 ?m; on decorticated wood, North American (western Canada and the United States).
.................................................................................................................................. G. corrugatum

cylindrical, pale brown, (2–)3–7(–11) septate, (13–)15–42(–48) × 2.5–5.5(–6) ?m; conidia similar to those of G.
schizosporum but without longitudinal septa, forming unbranched chains; on Betula, and Salix, Norway and
Switzerland.
