Type speciesRaffaelea ambrosiae Arx & Hennebert

NotesRaffaelea ambrosiae is associated with Platypus cylindrus on Quercus in the UK. Raffaelea is a genus associated with ambrosia beetles worldwide (Harrington et al. 2010, de Beer et al. 2013a, Musvuugwa et al. 2015, Simmons et al. 2016). These fungi commonly occur in symbioses with wood-boring ambrosia beetles, Coleoptera, Curculionidae, Scolytinae and Platypodina and cause sap stain or blue stain of freshly cut logs and affect timber quality. The genus is characterised by hyphae bearing typical phialides and conidiogenous cells with globose/ovoid to elongated conidia, often truncate at the base, with conidia budding yeast-like daughter cells. The sexual morph is undetermined.
