Two new species of Neopestalotiopsis from southern China

Abstract

Pestalotiopsis-like fungi are widely distributed in many plants and include endophytes, pathogens and saprobes. Five strains of Neopestalotiopsis were isolated from diseased leaves of Rhapis excelsa (Principes, Palmae), Rhododendron simsii and Rho. championiae (Ericales, Ericaceae) and Erythropalum scandens (Santalales, Olacaceae) in southern China. Based on morphology and multi-gene (ITS, tub2, tef1) phylogeny, our five strains of Neopestalotiopsis represent two new species and one extant species. Descriptions, illustrations and notes are also provided for the new species.

Pestalotioid Species Associated with Medicinal Plants in Southwest China and Thailand

“…Notes: Neopestalotiopsis hyperici is related to N. rhododendri and N. protearum in the phylogenetic analysis ( Fig. 1 ), but they can be distinct from concolorous conidia and the size of their median cells (10 to 14 μm in N. hyperici versus 14 to 20 μm in N. rhododendri versus 16 to 17 μm in N. protearum ) ( 13 , 44 ). In addition, there are 13 bp different between N. hyperici and N. rhododendri and 10 bp different between N. hyperici and N. protearum in the tef1-α region.…”

“…Notes: Neopestalotiopsis rhapidis was introduced by Yang et al ( 44 ) from leaf spot of Rhapis excelsa ( Arecaceae ) in China. Our isolate KUNCC 22-12590 clustered together with N. rhapidis (GUCC 21501) in the phylogenetic tree.…”

“…Our isolate KUNCC 22-12590 clustered together with N. rhapidis (GUCC 21501) in the phylogenetic tree. These two species have overlapping conidial measurements (17 to 25 × 5 to 8 μm for KUNCC 22 to 12590 versus (22 to) 25.5 × 4 (to 6) μm for GUCC 21501) ( 44 ). Both isolates were associated with leaf spots in China.…”

“…Notes: Neopestalotiopsis rhododendri was introduced by Yang et al ( 44 ) from the diseased leaf of Rhododendron simsii ( Ericaceae ) in China. Based on our phylogenetic analysis of combined ITS , tef1-α , and tub2 sequence data, our isolate MFLUCC 22-0130 clustered with the type species N. rhododendri (GUCC 21504) with good support (ML-BS = 99% and BYPP = 0.99).…”

Recommendations for use of annotations and persistent identifiers in taxonomy and biodiversity publishing

“…The new fungal species Neopestalotiopsis rhapidis Qi Yang & Yong Wang bis, sp. nov., published in Biodiversity Data Journal ( Yang et al 2021) has the identifier "MycoBank 840065" which resolves to the MycoBank record for this new name, available after logging in MycoBank.…”
