“…(), filamentous fungi, mostly Pezizomycotina , were prevalent in the clone libraries of marine sponges. In previous studies, 21 orders of Ascomycota ( Boliniales , Botryosphaeriales , Capnodiales , Chaetosphaeriales , Claromycetales , Diaporthales , Dothideales , Eurotiales , Helotiales , Hypocreales , Microascales , Moniliales , Mucorales , Onygenales , Phyllachorales , Pleosporales , Polyporales , Saccharomycetales , Sordariales , Trichosphaeriales , and Xylariales ) and eight orders of Basidiomycota ( Agaricales , Agaricostilbales , Corticiales , Malasseziales , Polyporales , Sporidiobolales , Tremellales , and Wallemiales ) were found in marine sponges (Höller et al ., ; O'Brien et al ., ; Wang, ; Gao et al ., ; Proksch et al ., , ; Wang et al ., ; Baker et al ., ; Li & Wang, ; Liu et al ., ; Paz et al ., ; Ding et al ., ; Rozas et al ., ; Wiese et al ., ; Zhou et al ., ; Suryanarayanan, ; Thirunavukkarasu et al ., ; Yu et al ., ), of which only two orders ( Saccharomycetales and Malasseziales ) were not filamentous fungi. Nonetheless, global sampling, deep sequencing, and application of multiple phylogenetic markers are necessary and will be greatly beneficial for revealing the diversity pattern of sponge‐associated fungi.…”
