THE FLORA OF NEBB ISK \ 



1. MUCOB Linne Spec. PI. II., 1655. L753. 



Saprophytic; mycelium spreading in and upon the substratum; sporangia 

 phores springing up here and t lure mi the mycelium, simple or branched; 

 sporangia round, many spore I; zygospores borne on tie- mycelium naked, 

 the copulating branches (suspensors) without outgrowths 



Etymology: Latin mucor, mould. 



This was the name of one of the eleven genera under which Linn'- in hi-. 

 Genera Plautarum included all fungi. 



Hucor mucedo Linne 1. c. (ill part). 



Sporangiophores erect, rigid, simple, 2 L5 cm. high; sporangia large, round, 

 100-200// in diam., the membrane quickly disappearing, leaving a small 

 collar-like fragment at the base; columella high-arched, cylindrical or 



truncate-conical, 70-140x50-80 //; spores rounded, cylindrical, or long 

 ellipsoid, 6-12x3-6// or sometimes larger, colorless or lighl yellow. 

 In my specimens the spores are regularly 8 10 //. aboul half as wide and rather 



strongly tinged with yellow. 

 On excrement of auimals and various decaying substances the world over. 

 Quite common on decaying insects in the water around Line,, in. l'l. 

 XIV., Pig. 1, a, b, c. 



Uncor racemoKiis Fresenius Beitraege 12. 1850. 



Chlamydomucor racemosus Brefeld Uhtersuch. 1890. 



Sporangiophores erect, of various sizes..") U) mm. high or small and frail. 

 richly and irregularly branched, each branch terminating in a sporangium; 

 sporangia small, round, of various sizes, depending on the nourishment, 

 20-70 p. in diam., the membrane not dissolving but splitting; columella 

 broad clavate or obovate; spores round or shori ellipsoid, smooth, color 

 less singly but in mass yellowish, 6 LOs 5-8 //. 



When grown in a solution it forms septa rapidly and grows by budding. In 

 this condition it forms ellipsoid or rounded-oblong chlamydosporee here 

 and there in the hyphae aud even in the sporangiophores. In its hud 

 ding state it is a ferment. 



On decaying organic substances the world over. On paste in the botanioal 



laboratories at the University and very c mon in BOlutions, neglected 



culture-media, etc., in the laboratory. PI X l\ *.. Pig. 2, a, l>, 0. 



2. PHYCOMYCES Kcxzi: Mycol. Hefte II., 113. 1823 



Mycelium radiate; sporangiophores simple, arising singly. 



strongly metallic, terminated by a large sporangium; sporangia round 

 many-spored, the membrane dissolving; columella pear shaped; conju 

 gating branches tong-shaped, the suspensors producing dichotomouslj 

 branched, dark brown projections. 



Etymology: Greek 0wco?, alga, and « . fungus. 



Phycomyces nitens (Agabdh) Kunzb L o. 

 r/ru niU ns Agardh. 1817. 



The characters of the genus. Sporangiophores i 30 cm. long; sporangia 



very large, about 1 mm.; spores ellipsoid, 16 30x8 15 . 

 A beautiful species, quickly recognized by it- metallic appearanoe. The 



sporangiophores have the look of small flatte 1 wires. 



On greasy, oily substances Also found <>n a squash at Lincoln. PI \l\
