Eupelte
Eupelte Syd., Annls mycol. 22(3/6): 426 (1924).
Index Fungorum number: IF 1932; Facesoffungi number: FoF 12210, 4 morphological species (Species Fungorum 2022), no molecular data available.
Colonies epiphyllous, dense, crustose, smooth, often cause yellow haloes around the colonies and yellowing on the corresponding lower surface of the leaves. Sexual morph: Thyriothecia scattered to grouped, initially orbicular, later elliptic to elongated, simple, straight, curved, often X to Y shaped, astomatous, dehisce vertically at the centre. Asci born on basal hymenium, clavate, bitunicate, become spherical at maturity eight spored. Ascospores conglobate, oblong, brown, uniseptate, constricted at the septa, wall smooth but becomes verrucose at maturity. Asexual morph: Hyphae partly superficial and partly immersed, superficial hyphae brown, septate, flexous, irregularly branched at acute to wide angles. External mycelium enters the host through stromata extended up to palisade tissues. Conidiophores arise from the external mycelium, mostly deep brown to rarely dark, 0–1-septate, erect, often curved, simple, solitary, smooth. Conidiogenous cells terminal, integrated, monoblastic, determinate. Conidia brown, 0−3-septate, not constricted, straight to curved, cylindrical obclavate, broadly rounded at the apex, truncate at the base, wall smooth (adapted from Hosagoudar 2009).
Type species: Eupelte amicta Syd.
Notes: Eupelte is characterised by superficial brown hyphae, deep brown to rarely dark, 0−1-septate conidiophores, monoblastic, determinate conidiogenous cells and brown, 0−3-septate conidia. The sexual morph is characterised by scattered to grouped thyriothecia, clavate, bitunicate asci and conglobate, oblong, brown, uniseptate ascospores. Arx and Müller (1975) transferred the type species of two other genera, namely E. dothideoides, type of Maurodothina, and E. farriae, the sexual morph of the type of Pirozynskia, P. farriae to Eupelte. Hence, the three genera Eupelte, Maurodothina and Pirozynskia are synonyms. Hosagoudar (2009) reported E. amicta from leaves of Olea dioica (Oleaceae) in India (Kerala) and provided an updated description of the genus. Rossman et al. (2016) suggested to use Eupelte over the other two genera. Molecular data is lacking for Eupelte. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Eupelte.
