03C08832FFFAFF9F4DBBCA96FD088C6A.taxon	discussion	Notes: Phylogenetically, Arthrobotrys gongshanensis forms a sister lineage to A. lanpingensis (95 % MLBS, 0.92 BYPP). Morphologically, both of them produce subfusiform or elongate-obovoid conidia with 1 – 4 - septate. However, they can be easily distinguished by their conidiophores. The conidiophores of A. gongshanensis produce 1 – 5 short denticles near the apex and bear 1 – 5 conidia, while the conidiophores of A. lanpingensis are simple and bear only 1 conidium (Zhang & Hyde 2014).	en	Yang, Yao-Quan, Zhang, Fa, Li, Zheng-Qiang, Zhou, Fa-Ping, Yang, Xiao-Yan, Xiao, Wen (2023): Morphological and multigene phylogenetic analyses reveal two new nematodetrapping fungi (Arthrobotrys, Orbiliaceae) from Yunnan, China.

03C08832FFF9FF9D4DBBCAFFFF498A2D.taxon	discussion	Notes: Phylogenetic analysis revealed that Arthrobotrys luzhangensis is related to A. koreensis, A. obovata, A. scaphoides, A. latisporus, A. botryospora, A. cladodes and A. robusta (91 % MLBS, 0.92 BYPP). In morphology, A. luzhangensis (1 – 4 - septate conidia) can be easily distinguished from A. koreensis, A. obovata, A. latisporus, A. botryospora, A. cladodes and A. robusta (0 – 1 - septate conidia) in the shape, size, septation number of conidia (Drechsler 1937, Duddington 1951, Barron 1979, Zhang et al. 1996, Su et al. 2011, Wu et al. 2012, Zhang & Hyde 2014). A. luzhangensis is more similar to A. scaphoides (Schenck et al. 1977). Their differences are as follows: 1) A. luzhangensis produces two types of conidia, while A. scaphoides produce one type conidia; 2) A. scaphoides produce 1 – 6 - septate conidia, while the conidia of A. luzhangensis have no more than 4 septa. In addition, the conidia of A. luzhangensis are shorter and thicker than those of A. scaphoide [A. luzhangensis, 23.6 – 66.9 (49.6) × 13.5 – 26.7 (20.2) µm versus A. scaphoide, 36.6 – 79.3 (57) × 11 – 17.5 (14) µm]; 3) The conidiophores of A. scaphoide bear 1 – 10 conidia by repeated elongation, while the conidiophores of A. luzhangensis bear 1 – 3 conidia on short denticles at the apex.	en	Yang, Yao-Quan, Zhang, Fa, Li, Zheng-Qiang, Zhou, Fa-Ping, Yang, Xiao-Yan, Xiao, Wen (2023): Morphological and multigene phylogenetic analyses reveal two new nematodetrapping fungi (Arthrobotrys, Orbiliaceae) from Yunnan, China.
