摘要
在进行黑龙江省药用植物根际土壤真菌多样性的研究中,分离获得了2个中国新记录种:蕨枝顶孢[Acremonium pteridii(J.C.Frankland)W.Gains]和穴形节皮菌的金孢属无性型[Chrysosporium anamowh of Arthroderma cuniculi(Dawson)C.A.N.van Oorschot]。蕨枝顶孢的主要形态特征为分生孢子梗单生或二次及三次分支,具有1~3个隔膜,顶端着生单个分生孢子;分生孢子以假头状着生,卵形或者近圆形,内含1个油球。穴形节皮菌的金孢属无性型主要形态特征为短的侧分支与可育菌丝呈直角伸出,分生孢子具柄,生于短的突起上或者直立的侧分支上;分生孢子卵形或棍棒形,顶端钝圆,基部平截,大多数单胞,极少数为由2~3个细胞组成。文中对它们进行了详细的形态特征描述,标本保存于大连民族学院菌种保藏中心。
During investigation of the rhizospheric soil-fungi of medicinal plants in Heilongjiang province of China, two newly recorded fungal species for China were isolated and identified. They are Acremonium pteridii and Chrysosporium anamorph of Arthroderma cuniculi. A. pteridii produces simple or branched conidiophores with one to three septa, and its ovate or subglobose conidia are often formed in slimy heads, containing one droplet. Chrysosporium anamorph of Arthroderma euuiculi produces orthotropic short side branches in hyphae, bearing terminal and lateral conidia. They are sessile or on very short protrusions or orthotropic side branches, thin-walled, obovoid to clavate, 1-celled or sometimes 2- to 3- celled. The two species were described in detail in this paper. All the fungal isolates were deposited in the fungal culture collection of Dalian Nationalities University.
