Foliophoma camporesii D. Pem & K.D. Hyde, in Hyde et al., Fungal Diversity 100: 28 (2020)
Index Fungorum number: IF556797; Facesofungi number: FoF 06466
Etymology: Named in honour of Erio Camporesi, a prolific collector of fungi from Italy and in recognition of his immense contribution to mycology.
Holotype: MFLU 17–1006
Saprobic or pathogenic on dead aerial stem of Maclura pomifera. Sexual morph: Undetermined. Asexual morph: Conidiomata 40–47 × 40–69 μm (x̄ = 43.3 × 48 µm, n = 20), pycnidial, globose to subglobose, ellipsoidal, or irregular, immersed to semi-immersed, carbonaceous. Pycnidial walls 15–40 μm, comprising 1–2-layered of cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 2–4 × 2–3 μm (x̄ = 2.6 × 2.2 µm, n = 20), phialidic with periclinal thickening or percurrent proliferation at apex, hyaline, smooth, globose to short cylindrical. Conidia 2–6 × 3–5 μm (x̄ = 4.9 × 3.9 µm, n = 20), ovoid to ellipsoidal, hyaline when immature, brown at maturity, aseptate, smooth- and thin-walled.
Culture characteristics: Colonies on MEA, 20–25 mm diam. after 7 days at 16 °C, margin regular, circular, aerial mycelia thinly hairy, white and flat; reverse grey and white at the margin.
Material examined: ITALY, Province of Forlì-Cesena [FC], Predappio Alta-Predappio, on dead aerial stem of Maclura pomifera (Moraceae), 5 May 2017, E. Camporesi, IT 3345 (MFLU 17–1006, holotype), ex-type living cultures, MFLUCC 18–1129.
GenBank Numbers: ITS: MN244200; LSU: MN244170; SSU: MN244176.
Note: Strain MFLUCC 18–1129 was isolated from dead stem of Maclura pomifera in Italy. Foliophoma camporesii has a close phylogenetic affinity to F. fallens, the type species of Foliophoma. It differs from F. fallens in having smaller conidiomata (40–47 × 40–69 μm versus 120–250 μm) and brown conidia. ITS nucleotide comparisons show a difference of 12 base pairs or 2% difference between our new taxon and F. fallens. We, therefore, introduce F. camporesii as the second species in Foliophoma.
