Mycelium consisting of branched, septate, smooth, pale brown hyphae. Sexual morph: Undetermined. Asexual morph: hyphomycetous. Conidiophores solitary, erect, cylindrical, straight to somewhat flexuous, basal cell bulbous, without rhizoids, stalk medium to dark brown, smooth, transversely euseptate, upper cell giving rise to (1–)2–4(–6) conidiogenous cells. Conidiogenous cells subcylindrical to allantoid or doliiform, straight to gently curved, pale brown, polyblastic, proliferating sympodially. Conidia hyaline, aggregating in slimy mass (never in chains), ellipsoid, apex subobtuse, base subtruncate (Crous et al. 2009).
Notes – Crous et al. (2009) introduced Brycekendrickomyces Crous & M.J. Wingf. to accommodate the type species B. acaciae Crous & M.J. Wingf. which has a simple conidiophore branching system, and ellipsoid conidia which are not in chains. Crous et al. (2009) compared the morphology of Brycekendrickomyces with Argopericonia (Incertae sedis), Haplographium (Hyaloscyphaceae, Helotiales, Leotiomycetes) and Lauriomyces (Lauriomycetaceae, Lauriomycetales, Incertae sedis). Brycekendrickomyces have a simple conidiophore branching system, while Haplographium and Lauriomyces have an intricate series of branched conidiophores and conidia arising in chains. Argopericonia has apical conidiogenous heads, and catenate conidia with a prominent, globose guttule (Crous et al. 2009). Phylogenetically, Brycekendrickomyces acacia (CBS 124104) formed a distinct clade in Chaetothyriales with 92% ML BS, 1.00 BY PP support in this study. We maintain Brycekendrickomyces in Herpotrichiellaceae pending further studies.
