Mycological Diversity Description I
Highlights
Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated as endophyte from Mimosa tenuiflora and causing post-harvest rot disease on fruits of Psidium guajava, respectively
Neopestalotiopsis egyptiaca is reported as new to the Americas and as causing post-harvest rot disease on fruits of Psidium guajava, while Umbelopsis isabellina is reported as endophyte
Q. fabacearum differs from Q. cyanescens mainly in the size of the conidiogenous cells ((5.5–) 9.5–13 (–34) × 1–2 μm in Q. fabacearum vs. 30–40 × 1.5–3 in Q. cyanescens), primary conidia (7.5–8.5 × 1.5–2.5 μm in Q. fabacearum vs. 3.5–6.5 (–25) × 2.5–3.5 in Q. cyanescens), secondary conidia ((3.5–) 4.5–5.5 (–6.5) × 1.5–2 μm in Q. fabacearum vs. 2.5–3.5 × 2–2.5 in Q. cyanescens), and in the presence of chlamydospores in Q. fabacearum
Summary
Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated as endophyte from Mimosa tenuiflora and causing post-harvest rot disease on fruits of Psidium guajava, respectively. Neopestalotiopsis egyptiaca is reported as new to the Americas and as causing post-harvest rot disease on fruits of Psidium guajava, while Umbelopsis isabellina is reported as endophyte.
