Cheilymenia crucipila with smaller spores?
Viktorie Halasu, 02-06-2017 14:33
Viktorie HalasuHello all,

did you ever see any collections of Cheilymenia crucipila with smaller spores? I measured 13,4-15,1 (15,7) × (7,2) 7,8-8,6 ?, average 14,1 × 8,2 ?, Q = 1,6-1,9 (exsiccate, spores from hymenium surface, in water), but usually I see collections with spores cca 15-18 × 8-9,5 ?. Ornamentation is rather big / coarse, hairs fit as well (IMHO). C. asteropila has similar spore size, but finer ornamentation and much longer marginal hairs. Can it still fall within this species variability, or would you consider it another taxon?

Thank you for your opinions.
Viktorie

Re : Cheilymenia crucipila with smaller spores?
All my collections have ascospores with a length greater or equal to 15 µm. Did you measure the spores from a spore-print?

Re : Cheilymenia crucipila with smaller spores?
Hello Nicholas,
it's a several years old exsiccate, unfortunately. I tried to take a few spores from the hymenium surface with the needle tip and did a standard thin section as well. I don't have here my notes, at sunday I'll check if there was any difference between those two preparates.
