Click to collapse Descriptions Info

Colonies velvety with floccose growth, grey olivaceous, dark olivaceous to brown, sporulating freely. Stromata not formed. Hyphae septate, olivaceous brown to pale brown, smooth, septate, 4.5-6 µm thick. Conidiophores pale brown, geniculate above, septate, cylindrical, simple, rarely branched, smooth, 50-150 x 5-7 µm. Conidiogenous node surface somewhat verrucose. Conidia elongate cylindrical, smooth, straight, sometimes somewhat curved, pale olivaceous brown to pale brown or brown, 8-11 distoseptate, (66) 138-190 x 11-14 µm, often distinctly marked by a thick dark transverse septum at one or both ends. Hilum truncate, slightly protruding. First septum in the conidia median, second septum delimits the basal cell and the third septum is distal. Germination is bipolar and lateral

Notes – Alcorn (1991) synonymised B. novae-zelandiae with B. portulacae based on conidial morphology. The phylogenetic tree inferred fromthe combined multilocus sequence alignment showed that the two ex-isotype isolates of H. portulacae (BRIP 14541) and B. novae-zealandiae (BRIP 14837) are identical, thereby supporting Alcorn’ssynonymy (Fig. 1). This species is transferred from Bipolaris to Curvularia based on multilocus phylogenetic analysis (Fig. 1)
