Boeremia galiicola

Boeremia galiicola Jayasiri, Camporesi & K.D. Hyde, in Jayasiri, Hyde, Jones, Jeewon, Ariyawansa, Bhat, Camporesi & Kang, Mycosphere 8(8): 1089 (2017)


Index Gungorum: IF 552360


Saprobic on dead stems of Galium sp. Sexual morph: see Jayasiri et al. (2017). Asexual morph: Conidiomata 200–300 μm diam., 200–250 μm high, black, pycnidial, solitary to gregarious, or confluent, subepidermal or peridermal in origin, immersed to partly erumpent, globose to subglobose, unilocular, glabrous, thick-walled, papillate. Ostiole short, single, centrally located. Conidiomatal wall 30–40 μm wide, composed of thick-walled, dark brown to hyaline cells of textura globosa to textura angularis, becoming thickened at the basal and upper part. Conidiophores occasionally present, hyaline, doliiform to subcylindrical, arising from inner layers of the pycnidial wall. Conidiogenous cells 5–8 × 4.5–7 μm, hyaline, enteroblastic, phialidic, ampulliform, determinate, smooth. Conidia 8–13 × 3–4.5 μm ( ̄x = 10 × 3.5 μm; n = 30), hyaline, cylindrical obtuse, 0–1-septate, occasionally slightly constricted at the septum, straight or slightly curved, thick- and smooth-walled, guttulate.


Material examined: Italy. Province of Forlì-Cesena, Bagno di Romagna, near Lago Pontini, on dead stems of Galium sp. (Rubiaceae), 28 April 2015, Erio Camporesi, IT2464 (MFLU 15-1341, holotype); (KUN, HKAS 93620)


Notes: The conidia of this collection (MFLU 15-1341) did not germinate, and the sequence was obtained directly from fruiting bodies.
