Notes.

Based on the asexual morph of species in Jenniferia, they share similar characteristics in producing grey mycelium covering the spider host and multiple cylindrical synnemata from all parts of the host. The phylogenetic analysis supported J. cinerea as a sibling species to J. griseocinerea, but they have differences in producing synnemata. Jenniferia cinerea produces long synnemata, while J. griseocinerea produces short and long synnemata (Fig. 6). Jenniferia cinerea was not found as a sexual morph, whereas both J. griseocinerea and J. thomisidarum were found with sexual and asexual morphs (Tables 2 and 3). The shape of conidia in J. cinerea is clavate, but conidia in J. griseocinerea are fusiform and in J. thomisidarum are fusiform to cylindrical (Table 3). The spider hosts of J. cinerea from both specimens presented herein are identified as Amyciaea sp. belonging to the family Thomisidae .
