Exophiala eucalyptorum Crous, sp. nov. MycoBank MB504533. Fig. 17. Etymology: Named after its occurrence on Eucalyptus leaves. Exophialae spiniferae similis, sed conidiis fusoidibus-ellipsoideis, (5–)6–8(–10) × (3–)4–5(–7) µm, et cellulis conidiogenis saepe catenatis, in catenis brevibus, dividentibus. Mycelium consisting of smooth to finely verruculose, branched, septate, 2–4 µm wide hyphae, at times giving rise to chains of dark brown, fusoid-ellipsoid chlamydospores, which can still have phialides, suggesting they were conidiogenous cells; hyphae becoming constricted at septa when fertile. Conidiophores reduced to conidiogenous cells. Conidiogenous cells numerous, terminal and lateral, mono- to polyphialidic, 5–15 × 3–5 µm; loci 1–1.5 µm wide and tall, with inconspicuous collarettes, at time proliferating percurrently; conidiogenous cells fusoid-ellipsoid, and frequently breaking off, appearing as short chains of conidia, but distinct in having conidiogenous loci. Conidia fusoid-ellipsoid, apex acutely rounded, base subtruncate, (5–)6–8(–10) × (3–)4–5(–7) µm; frequently becoming fertile, septate and brown with age. Cultural characteristics: Colonies erumpent, convex, smooth, slimy, margins feathery to crenate and smooth; aerial mycelium absent, growth yeast-like. Colonies on PDA, OA and SNA chestnut on surface and reverse. Colonies reaching 4 mm diam after 2 wk on PDA at 25 °C in the dark. Specimen examined: New Zealand, Wellington Botanical Garden, on leaf litter of Eucalyptus sp. (Myrtaceae), Mar. 2004, J.A. Stalpers, holotype CBS H-19905, culture ex-type CBS 121638 = CPC 11261. www.studiesinmycology.org Notes: Exophiala eucalyptorum is rather characteristic in that, in culture, chains of conidiogenous cells frequently detach from hyphae, appearing as short, intact chains of fertile conidia. Its phylogenetic position is somewhat outside the core of the Herpotrichiellaceae containing most Capronia teleomorphs and the remaining opportunistic Exophiala species, but still within the Chaetothyriales (Figs 1–2). Members of Venturiaceae Anungitea B. Sutton and Anungitopsis R.F. Castañeda & W.B. Kendr. Sutton (1973) erected the genus Anungitea to accommodate species with brown, mononematous conidiophores bearing apically aggregated, flat-tipped, subdenticulate conidiogenous loci that give rise to chains of pale brown subcylindrical conidia with thickened, darkened hila. He compared the type species, A. fragilis B. Sutton with anamorph genera of the Mycosphaerellaceae, but did not compare it to Fusicladium, to which it is remarkably similar. Castañeda & Kendrick (1990b) introduced the genus Anungitopsis based on A. speciosa R.F. Castañeda & W.B. Kendr. This genus was distinguished from Anungitea by its formation of subdenticulate conidiogenous loci distributed along the apical region of the conidiophore, and by the relatively poorly defined appearance of these loci. No cultures are available of the extype species of Anungitea, but we studied strains of Anungitopsis 203
