中国海南滨海森林中的伞菌新种——海南小丽蘑
Calocybella hainanensis sp.nov.—a new agaric species from coastal forests in Hainan,China
摘要
Abstract
Hainan Province is situated at the northern edge of the Asian tropics,serving as China's only tropical province.The province harbors exceptional biodiversity due to its unique geography and climate,particularly in fungal diversity.However,previous mycological surveys in Hainan are predominantly focused on central forested regions,while coastal ecosystems are largely overlooked.This study reports the first discovery of the genus Calocybella in China,with one new species and one new record for China collected from coastal Casuarina forests.Calocybella hainanensis sp.nov.is characterized by its ginger-yellow to yellowish-brown pileus,pale yellow lamellae,and small,oblong-ellipsoid basidiospores(4.9-5.5 × 2.3-3.1 μm)with faint ornamentation and inamyloid reaction.The newly recorded species,Calocybella sribuabanensis,exhibits gregarious growth,yellowish-brown pileus,densely arranged lamellae,and ellipsoid,faintly ornamented,inamyloid basidiospores.Phylogenetic analyses based on ITS sequences reveal that C.hainanensis forms a unique evolutionary lineage within Calocybella,but it shows unresolved affinities to other taxa.C.sribuabanensis forms a sister lineage with the Indian species Calocybella dicholamellata.关键词
