Neopestalotiopsis formicarum S.S.N. Maharachchikumbura, K.D. Hyde & P.W. Crous, Studies in Mycology 79: 121. 2104

C onidia comprise five cells (19.7–27.8 × 5.5–7.5 µm) with 3–5 septa and 2–3 appendages (10–23.7 µm). The colony was whitish to pale honey, vigorous and cottony mycelium. Median cell was versicolor with staining ranging from olive brown to dark brown. Intense conidia production in PDA medium was also observed by SEM ( Table 3 , Figure 3D–F ).

Material examined: Brazil, Amazonas State, Manaus, on leaves of guarana plants ( Paullinia cupana var. sorbilis ), 11 Sep. 2017, G. F. Gualberto, ex-type culture ( INPA 2916 ) .
