Melanocamarosporioides D. Pem, R. Jeewon, Gafforov & K.D. Hyde, in Pem et al., Mycol. Progr. 18(3): 473 (2019).
Index Fungorum number: IF 554296; Facesoffungi number: FoF 04363, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on dead trunk and branches of Lonicera. Sexual morph: Unknown. Asexual morph: Coelomycetous. Conidiomata pycnidial, scattered, solitary or gregarious, superficial to erumpent, uniloculate, globose to subglobose, glabrous, black, ostiolate. Conidiomata wall nearly of the same thickness, composed of 3–7 layers of flattened cells, smooth, brown to dark brown, at the base hyaline to light brown pseudoparenchymatous cells arranged in a textura angularis. Ostiole single, circular, central, depressed. Conidiophores reduced to conidiogenous cells. Conidiogenous cells annelidic, holoblastic, discrete oblong to ampulliform, hyaline to dark brown, multiseptate, smooth-walled. Conidia solitary, globose, ellipsoidal or ovoid with obtuse ends, primarily hyaline, becoming pale brown to dark-brown at maturity, multiseptate mostly 3–4-transverse-septa, 1–3-longitudinal-septa, with several segments, slightly constricted at the septa, smooth and thick-walled (adapted from Pem et al. 2019).
Type species: Melanocamarosporioides ugamica D. Pem, R. Jeewon, Gafforov & K.D. Hyde
Notes: Melanocamarosporioides is characterised by unique completely superficial conidiomata, heavily pigmented with regular arrangement of cells within the peridium, and large dark brown, multiseptate conidia. Melanocamarosporioides is a well-supported distinct genus in Melanommataceae. Molecular markers available for Melanocamarosporioides include LSU, SSU, ITS and TEF-1.
