Re : Lasiobolus intermedius?
Hi Joop,
I hold also as Lasiobolus intermedius, however, had never seen warty spores and such with mucus cover. Bezerra et Kimbrough (1974) also write over nothing. Picture 4 and 5, could be "often collapsed at one side " (Bez. et Kimbr.) ?
Greetings Peter.

Re : Lasiobolus intermedius?

Hello PLeter,


I do not have the documentation from Bezerra et Kimbrough (1974) can you send me a copy?



For the rest the wrats were only visible with immature spores in Lugol and the sheath often contains these wrats and makes it easier to see.


It seems the sheath is also visible inside the ascus in Congo Red.


 


Joop
