Observation 60916: Lacrymaria glareosa
When: 2010-09-13
Herbarium specimen reported

Notes: growing on a lawn in a cluster; the cap, as far as I can judge, is not always that scaly, these scales are in fact the fuzzy fibrils typical for the species stuck together, probably because of the preceding dry spell. These are quite different from L. lacrymabunda posted by Anna (observation 60848)

not sure about the US,

but as far as I understand L. glareosa is more yellowish than L. velutina and the key distinction is not in the spores but in the shape of the cheilocystidia which in case of L. glareosa have these funny-looking apical projections.

Honestly, I personally think that it’s more tricky than that and that there might be some transitional forms – for example, our local specimens (identical visually to those in the first photo) have spores which are imperceptibly narrower and rougher, and only some cheilocystidia of the specimens I’ve looked at microscopically bear apical projections.

dont look roughened like the Lacrymaria I see. does anyone know how other Lacrymaria spp spores compare? how many Lacrymaria are in the US? how are they typically distinguished?

suggests it’s Lacrymaria glareosa. Nina Filippova took microphotographs of the specimen, which show spores which are slightly larger than those of L. lacrymabunda and funny-shaped cystidia.

I’m adding some pictures of the same fungi (the yellowish form) from a colony which grows right near my house, several hundred km S from the first observation location (first image). The colony’s been fruiting for years throughout the warm season so I’ve been able to observe some variability.
Note the warm, golden-brown hue of the cap and stipe in all photos and how the cap of a large specimen is crackled and almost smooth – caused by dry weather.
