摘要
报道了源于我国黑龙江的小孢盘菌属Acervus一新种,即黑龙江小孢盘菌A.heilongjiangensis。该种的显著特征为子囊盘杯状,无柄,直径5–10mm;子实层新鲜时黄色;外囊盘被为角胞组织至表层组织;子囊具囊盖,具8个子囊孢子,孔口在Melzer试剂中不变色,98–119×6.5–8.5μm;子囊孢子椭圆形,无分隔,9–10.5×3.9–5.5μm。对该种的形态学特征进行了描述和图示,并对其分类地位提供了DNA序列分析的佐证。
A new species of Acervus from Heilongjiang Province of China is described and illustrated, it is characterized by apothecia cupulate, sessile, 5-10mm diam., hymenium yellow when fresh, ectal excipulum of textura angularis to textura epidermoidea and medullary excipulum of textura intricata mixed with textura angularis; asci operculate, 8-spored, Jin Melzer＇s reagent and 98-119×6.5-8.5μm, ascospores ellipsoid, unicellular and 9-10.5×3.9-5.5μm. Both morphological features and 28S rDNA sequence data support the establishment ofA. heilongjiangensis as a new taxon
