Notes:
The paler brown grown on the ectal excipulum is mentioned in various references as being just another feature of this fungus, but I observed what appeared to be asexual propogules budding off of this tissue, as shown in the first two micrographs. My apologies that of everything I managed to get written down, I apparently forgot to record the mounting medium and magnifications. figures.

note traces of purple, olive and brown in KOH pigment extraction

Paraphyses: long, filliform, ~1-2um wide, narrowly tapered at ends

Asci: 8-spored, inoperculate, seemingly without amyloid apical apparatus

Spores:

inaequilateral, narrowly ellipsoid, tapered at one end, some 1-septate and/or biguttulate

The only reference

to possible asexuality I have seen so far comes courtesy of Dr. Pfister’s reply to a recent email on this subject; Thaxter, R. 1923. The Genera Midotis, Ionomidotis and Cordierites, by Elias J. Durand. Proceedings of the American Academy of Arts and Sciences. 59:1-18

Thaxter refutes the condal nature of the paraphyses mentioned by Durand. While both of them are probably refering to the same structures we’ve been discussing on MO, I don’t know why they would think they were paraphyses, as the structures in question are located on the abhynenium.

Got to visit Fairyland. I have always heard about it, but have never visited myself. Even know the story of it.
