Observation 159602: Disciseda candida (Schwein.) Lloyd
When: 2014-02-12

Notes: mousey grey endoperiidum with slight pink tones at the very apex. A stellate-like wrinkled pattern around the ostiole at the apex. The exoperidium is encrusted with soil on the outside, smooth on the inside. Remnants of the glabrous gelatinous layer is gone (found in between exo and endo), but the reticulate pattern on the endoperidium, under the exoperidium is obvious in all fruitbodies. Spores are about 5um. I did not take photos of the spores. But the size matches.

I have never seen this species here at this park, and I walk my dog here every day. Hmmmm. We have not had any rain for a long time, and now lots of moisture for about a week. Now these guys are growing. Now I want to go check every park everywhere for Disciseda. Two of the six fruitbodies were ostiole side down, with the “sand case” up, and the others were with the ostiole side up (sand case down). This is GREAT, because it shows that these guys, at least this species and this collection does exhibit the “rolling over” described by many authors. The “rolling over” of Disciseda is a debate for some of us interested in this genus.
This is a nice collection. And, of course, I spent another hour searching every corner of the park looking for more and did not find any. I came across this COMPLETELY RANDOMLY. Which, unfortunately, is always how I find species in this genus (except in a few cases where I know they grow annually).

Is the reticulate pattern a character for candida?
I haven’t really known how to tell D. candida and D. bovista apart.

These might also be Geopora, Steph.

Microscopy?

If Geopora (Geopora arenicola?), then peridium should have some “fuzz” holding the soil to the sporocarp. Might also account for why so much soil is still adherring. Supposed to be fairly common in CA, but I have not seen it in OR. Geopora arenicola aka “Hole in the Ground”, often with sandy particles attached to peridium.

Found on soil, at the edge of the grassy baseball field, along the fence line, near decayed wood chips but not in the wood chips. The soil here has been dry and compact, but now is soaking wet from all the rain in the past few days.
