中国花耳科的五个新种

本文报道了产于中国的花耳科Dacrymycetaceae的五个新种:小胶杯菌Femsjonia minor Liu et Fan sp.nov.,中国胶杯菌F.sinensis Liu et K.Tao sp.nov.,叶状假花耳Dacryopinax foliacea Liu et Fan sp.nov.,大孢假花耳D.macrospora Lin,Fan et Y.M.Li sp.nov.,以及湖南胶角菌Calocera hunanensis Liu et K.Tao sp.nov.。小胶杯菌与该属其它种的区别在于子实体小型、孢子分隔处缢缩且常具纵隔、不孕面光滑以及皮层菌丝多分枝且顶端膨大;中国胶杯菌与该属其它种的区别在于菌丝无锁状连合;叶状假花耳及大孢假花耳与本属其它种的区别主要在于多隔的孢子(3个隔以上)。假花耳属这两个新种在宏观形态上非常相似,但大孢假花耳的孢子为35—40×10—12.5μm,具7—15隔;叶状假花耳的孢子为15—22.5×4.5—6.5μm,具3—7隔;湖南胶角菌的主要特征是担子果呈羊肚菌状,偶裂成分叶状,孢子具1薄壁的横隔。所有新种的主模式标本均保藏于山西大学真菌标本室。

FIVE NEW SPECIES OF DACRYMYCETACEAE FROM CHINA

Five new species of Dacrymycetaceae are described from China in this paper. They are Femsjonia minor Liu et Fan, F. sinensis Liu et K. Tao, Dacryopinax joliacea Liu et Fan, D. macrospora Liu, Fan et Y. M. Li, and Calocera hunanensis Liu et K. Tao. Of these, Femsjonia minor is characterised by small basidiocarps, spores slightly constricted at septa, a few of the median cells longitudinally divided and the cortical hairs branched frequently and inflated apically. Femsjonia sinensis is characterised by lacking of clamp connections. Both Dacryopinax foliacea and Dacryopinax macrospora differs mainly from other species of Dacryopinax in the characters of larger and multi-septated spores. The two new species of Dacryopinax are similar to each other in shape, but the spores of D. macrospora are 35—40×10—12.5 u.m, with 7—15 septa, while in D. foliacea, they are (12.5—) 15—22.5×4.5—6.5μm, with 3—7 septa. Calocera hunanensis is mainly characterised by morchelloid basidiocarp, occasionaly lobed apically, and the spores with one thin-walled septum. All the type specimens of the new species are deposited in the Mycological Herbarium of Shanxi University (MHSU).
