Lasiobolus macrotrichus

Found on deer dung.


Fruitbody: 297 um wide - 305 um high, covered with straight setea originating from the base.
Setea: Non sepltated with round and pointed tops, thick walled.
Setea with round tops - 234-280x24.5-25 um (width measured at the base), wall 1.5-1.8 um
Setea with pointed top: 334-380x26-27.5 um (width measured at the base), wall 3.0-3.2 um
Pararyses: rounded top, septated, width 2.1-2.4 um
Asci: 8-spored, 149-170x13-14.5.
Spores: ellipsoid, thick walled, 18.5-20x7-7.5 um.


No free spores were found so only spores inside asci were measured but difference in final measurement will not be that much I think.

Re : Lasiobolus intermedius?
No, Joop, I'don't think, that your species is Lasiobolus intermedius.
It must have somewhat shorter and broader, more elliptical spores.
Maybe, that the spores in the asci, you show us, are not mature, but however your species should be Lasiobolus macrotrichus.
The narrow, more or less fusiforme spores are typical for this species!
