摘要
在湖北省十堰市龙泉寺旅游区采集到一株小蘑菇属Micropsalliota真菌,经鉴定为Micropsalliota lateritia Heinem.,为中国新记录种.该种的主要特征是子实体小,紫褐色,表面覆盖丛毛状小鳞片;菌褶离生,不等长;菌柄圆柱形,紫红色,菌环膜质,易脱落;孢子椭圆形,无萌发孔,5.2~5.8×3.5~3.8μm;缘囊体棍棒状或近头状,侧囊体缺;菌盖皮层菌丝有色素.小蘑菇属主要分布于热带地区,其新分布点的发现,对小蘑菇属的系统分类与演化的深入研究具有重要意义.研究标本存放于汉江师范学院真菌标本室(HMHNU).
Micropsalliota lateritia Heinem. , a member of Micropsalliota was discovered from Longquan temple tourist area of Shiyan City in Hubei Province, and was a newly recorded in China. This species is characterized by small, violet brown, floccosesquamulose; lamellae free with two series of lamellulae; stipe cylindrical, violet red, usually curving; presence of pendent fugacious annulus; spores 5.2-5.8×3.5-3.8 μm, on average 5.5 × 3.6 μm, ellipsoid, without germ pore; Cheilocystidia broadly clavate or seldom subcapitate, absence of pleurocystidia and pileipellis hyphae incrusted with pigments. The genus has its greatest diversity in tropical habitats, the discovery of the distribution point have great significance for the further research of the system classification and evolution of Micropsalliota. The specimens examined were deposited in the Herbarium of Mycology of Hanjiang Normal University （HMHNU）.
