Epichloe. 



687. Epichloe typhina (Fries) Tulasne, Syll. II "«, Wt. II ''' c. icon.,

 02 a ^°' c. icon.). 



The mycehum of this fungus is perennial in the host-plant; P. Niel- 

 sen has divided a single infected tuft into many parts and all of them 

 produced affected straws only. Its conidial fructification is called 

 Sphacelia typhina Sacc, Syll. IV ^*^ Ldau IX ''^'. Rostrup supposes that 

 this species should be divided into more biological forms (R 96 o ^^*}.

Cordyceps. 



It is a general supposition, and not disproved, that the species of 

 the present genus correspond to forms of Isaria; for instance: 



Cordyceps militaris corresp. to Isaria farinosa (= crassa, truncata 



etc.). 



— cinerea — — eleutherarum. 



— sphingum — — sphingum (see Tul. Carp. 



iir^). 



— pistillariaeformis — — lecaniicola (see Jaap 08 ^''). 



— sphecophila — — sphecophila (see R 93 b '^). 



A few species correspond to forms of Botrytis for instance: 



Cordyceps melolonthae corresp. to Botrytis tenella (Ldau VIII ^^^y 



— sp. - muscae (R 93 b '=).
