Hyaline spores

Psathyrella uligincola is not described with hyaline spores. We really should address this before we continue using this name….

See obs 119603 & ignore what I said about them turning hyaline in KOH, they are just hyaline, in H2O, in KOH, etc… A few other Psathyrella species are described with spores like this, P. uliginicola is not one of them…
