Hello Ismail,
no chance of identification with only the spore size, which seems to be from dead spores. If they are from living spores, then they are exceptionally narrow and I have no idea of it. If they are dead it could PERHAPS be M. lividofusca. The boomerang shaped spores occure often in that species, but they are not signifacnt enough for a determination. Usually M. lividofusca has a brownish subhymenial layer just below the ascus bases.
Did you check the KOH reaction, wether it is negative or may be yellow? (I suppose it will be negative)
best regards,
Andreas
thank you very much
