Phylogenetically, these isolates formed a highly supported clade (ML / BI = 100 / 1) with the ex-type strain of D. apiculata (CGMCC 3.17533) (Fig. 2). To our knowledge, this is the first report of D. apiculata associated with Castanopsis and Lithocarpus species, expanding the known host range of this fungus to Fagaceae .</p></div>	https://treatment.plazi.org/id/0E95B2B81934500286146D096E8F9295	Public Domain	No known copyright restrictions apply.

( Annonaceae) in Thailand (Udayanga et al. 2012). In the current study, three isolates recovered from Cyclobalanopsis kerrii and Lithocarpus levis clustered with the ex-type strain of D. siamensis (MFLUCC 10-0573 a) with maximum statistical support (ML / BI = 100 / 1) (Fig. 3). These findings constitute new host records for D. siamensis on Cyclobalanopsis and Lithocarpus species, broadening the known host range of this pathogen to the family Fagaceae .</p></div>	https://treatment.plazi.org/id/CAAC3F4F2F585446B5D15DFF3C6C1B66	Public Domain	No known copyright restrictions apply.
