Etymology.
Capillidium jiangsuense (Lat.), referring to the region where the fungus was isolated.
Known distribution.
Jiangsu Province, China.
Typification.
China, Jiangsu Province, Jurong City, Tianwang Town, 31°6'94"N, 119°26'91"E, from plant debris, 25 Mar 2018, Y. Nie, culture ex-holotype CGMCC 3.16168 (= RCEF 6545).
Description.
Colonies on PDA at 21 °C after 3 d white, reaching ca. 21 mm in diameter. Mycelia haline, often unbranched, vegetative hyphae filamentous, 5-10 μm wide. Primary conidiophores unbranched, producing a single primary conidium, widening upwards near the tip, 50-240 × 6-10 μm. Primary conidia forcibly discharged, subglobose to turbinate, 21-31 × 12-29 μm. Papilla 4-10 μm wide, 2-4 μm long. Replicative conidia two kinds on 2% water agar, arising from primary conidia, one similar and smaller to the primary conidia, the other elongate and passively detached, 17-32 × 10-15 μm. Slender secondary conidiophores unbranched, 65-120 μm long, 2.5-3 μm wide at the base, tapering gradually to a width of 1 μm at the tip. Resting spore not observed.
Notes.
Morphologically, the present isolate resembles Ca. denaeosporum because of the size of its primary conidia (13-32 × 6-21 μm in Ca. denaeosporum vs. 21-31 × 12-29 μm in Ca. jiangsuense ) ( Drechsler 1957). However, Ca. denaeosporum has larger capilliconidia (10-18 × 6-10 μm in Ca. denaeosporum vs. 17-32 × 10-15 μm in Ca. jiangsuense ) and longer, more slender secondary conidiophores (35-65 μm in Ca. denaeosporum vs. 65-120 μm in Ca. jiangsuense ) ( Drechsler 1957). Although they grouped together with relatively little divergence on the phylogram, DNA similarity levels between the two species are only around 97.9% (nucLSU) ( Nie et al. 2012). This evidence supports the present isolate being a new species, which we have named Capillidium jiangsuense sp. nov.
