I will do that in the future.

Concerning Sclerodermataceae, I also found this.

“Spores acquire their spiny and reticulate character as they mature and can be misleading if taken too young. It should be clear when using spore measurements whether the ornamentation is included.”

And give that number separately.

what i tough is wise to do, is to not count the ornamentation and then add the ornamentation size with the measure (ex 11u spore with 0,5 ornamentation) but this might not be necessary on not that much ornate spore, might be me however.

Measuring spores?

When measuring the spores for species like this that have a raised ornamentation, is it best to include the ornamentation in the general size or to exclude it? There seems to be some lack of consistency depending on what group/author there is? For this observation, I included it as it was easier.
