Fumiglobus D.R. Reynolds & G.S. Gilbert, Cryptog. Mycol. 27(3): 252 (2006).
Saprobic on host. Sexual morph: Unknown. Asexual morph: Mycelium superficial, sometimes becoming aerial, membranous or loosely formed, composed of dark brown or blackish, constricted hyphae. Pycnothecium formed from several hyphae or from intercalary hyphal cells, globose to subglobose, glabrous. Conidia hyaline, bacillate to ellipsoidal or cylindric (adapted from Reynolds and Gilbert 2006).
Type species: Fumiglobus ficinus (Bat., Nascim. & Cif.) D.R. Reynolds & G.S. Gilbert
Notes: Fumiglobus is characterised by superficial mycelium, pycnothecia formed on intercalary hyphal cells, and hyaline, bacillate to ellipsoidal or cylindric conidia. Batista and Ciferri (1963b) redescribed Spegazzini’s type specimen and description of the taxon Asbolisia sensu Batista, Nascimento and Ciferri. Sutton (1977) and Petrak (1929) reported the name Asbolisia as ‘dubious’. Kirk et al. (2001) stated the taxon as nomen dubium. Reynolds and Gilbert (2006) proposed the name, Fumiglobus, for the genus Asbolisia nomen confusum. The authors observed the specimens cited in Batista and Ciferri (1963b) and Spegazzini’s material and reported that Batista and Ciferri (1963b) identified a different sooty mould genus commonly found in the tropics characterised by intercalary or terminal fruiting bodies becoming globose, glabrous, with ostiolate structures forming a variety of unicellular, hyaline, ellipsoid or cylindrical conidia. Hansford (1946) considered Cicinnobella species as the asexual state of hyperparasites of Dimeriaceae genera in the Pleosporales. Hughes (1976) reported that Asbolisia was doubtful considering the observations made by Hansford (1946). Kirk et al. (2001) reported that Batista and Ciferri (1963b) introduced the family Asbolisisiaceae for these asexual species of Capnodiaceae characterised by darkly pigmented mycelium and reproductive features, that occur on living plant surfaces. Kirk et al. (2001) also reported that Batista and Ciferri (1963b) excluded Spegazzini’s type, A. ampullula, from the genus based on the putative synonymy with Cicinnobella ampula and wrongly designated a Brazilian species, A. citrina as a lectotype. Fumiglobus resembles Neoantennariella and Neoasbolisia in forming pycnidial conidiomata but is unique in having a pycnidium that lacks an elongated neck and has at most a rudimentary stalk. In the phylogenetic analyses of Abdollahzadeh et al. (2020), Fumiglobus cluster in a well-supported lineage in Neoantennariellaceae. LSU, SSU and ITS sequence data are available for only one species F. pieridicola.
