Notes: Nagrajchalara agathidis is characterized by simple conidiophore with a 1–3-celled basal stalk and a terminal phialide, versicolorous conidiogenous cells with gradual transition from venter to collarette, subellipsoidal to subcylindrical venter, and 1-septate and longer conidia (Nag Raj and Kendrick 1975). Morphologically N. agathidis superfcially resembles N. angionacea, but difers from it by longer and narrower venter, collarette and conidia (Nag Raj and Kendrick 1975). It is also similar to Chalara alabamensis, but difers in its versicolorous phialides (Morgan-Jones and Ingram 1976). The Chinese collections were with signifcantly longer phialides and collarettes (phialides 61–67 µm long, venters 22–28 µm long, and collarettes 34–46 µm long in the original description, Nag Raj and Kendrick 1975).
The following species under Chalara s. lat. are also with septate conidia and most likely also belong to the genus Nagrajchalara (Nag Raj and Kendrick 1975; Gadgil and Dick 1999; McKenzie et al. 2002). However, no living strain or DNA sequence was available for molecular phylogenetic analysis, thus their phylogenetic relationship with other chalara-like fungi within Leotiomycetes remains to be studied in future [includes C. aotearoae].
Notes: Chalara aotearoae is characterized by 2- to many-septate conidiophores (65–280 × 6.5–8 µm) with a main stipe and a terminal phialide (59–69 µm long), subcylindrical venter (22–33×8–10 µm), cylindrical collarettes (31–42×5–6.5 µm), and hyaline, uniseptate and cylindrical conidia (13–18×3.5–5 µm) with rounded apex and truncated base, bearing minute marginal frills.
Notes: Compared with the original description (conidiophores 60–65 µm long, phialides 53–64 µm long, and conidia 13–18×3–3.5 µm long), this fungus from the Chinese specimens was with slightly longer conidiophores, phialides and conidia (Nag Raj and Kendrick 1975).
