Mucoharknessia anthoxanthi Dissan., Camporesi & K.D. Hyde, in Li et al., Fungal Diversity 78: 10.1007/s13225-016-0366-9,  (2016)
Index Fungorum number: IF 551752; Facesofungi number: FoF 01651
Etymology: Referring to the host Anthoxanthum odoratum L.
Holotype: MFLU 15–3477
Saprobic on dead stems of Anthoxanthum odoratum. Sexual morph: Undetermined. Asexual morph: Conidiomata 240–320 μm high × 215–280 μm diam., globose, immersed to erumpent, brown, wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 7–14 × 4–5 μm lining the inner cavity, hyaline, smooth, ampulliform to subcylindrical, proliferating percurrently at the apex. Paraphyses 25–45 × 3–4 μm intermingled among conidiogenous cells, hyaline to pale brown, smooth to verruculose, subcylindrical with obtuse ends. Conidia 18–30×8–10μm (x̄ = 24 × 9 μm, n = 30), solitary, hyaline, smooth-walled, guttulate, fusoid-ellipsoid to subcylindrical, straight to curved, apex apiculate, tapering at base, apex with flared mucoid
appendage, up to 20 μm long, 15 μm diam.
Material examined: ITALY. Province of Forlì-Cesena [FC], Passo delle Forche - Galeata, on dead stem of Anthoxanthum odoratum (Poaceae), 24 November 2012, Erio Camporesi IT 981 (MFLU 15–3477), ex-type living cultures MFLUCC 15–0904, CGMCC.
Notes: The genus Mucoharknessia was introduced in Botryosphaeriaceae by Crous et al. (2015) based on Cortaderia selloana L. from Argentina. Based on multi-gene phylogenetic analyses (Li et al.2016), our isolate clustered close to M. cortaderiae. We introduce a new species, Mucoharknessia anthoxanthi based on its distinct morphological characters (Li et al. 2016).
