Observation 138346: Stemonitopsis typhina (F.H. Wigg.) Nann.-Bremek.

When: 2013-06-12

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

Notes:
These were rowing on an old log in mixed woods in the Big Sandy Creek Unit.
Total height of ~ 4mm(stalk ~ 1mm)
Spores purple brown.
Spores ~ 6.2-8.0 microns, round and moderately warted or spinulose, no reticulations.
Stemonitis nigrescens is a weak ID since the spores may be a little small and couldn’t find a lot of consistent information on these types of Slime Molds.
Edit 7/19/2013;
Steven Stephenson, the co-author of “Myxomycetes A Handbook of Slime Molds” suggested that Stemonitopsis typhina was a better possibility for these.
The spore size and ornamentation are also very close to what is reported in the handbook; “…faintly punctate with scattered clusters of dark warts, 6 to 8 micrometers in diameter.”
