I would call it a Hymenogaster species. Would have to study it to determine species. Interesting find from an understudied geographic area.

Yeah, I was perplexed

of Rhizopogons are rhizomorphs on the peridium. Of your collection of 11 sporocarps, I see only 3 rhizomorphs.

There are many other possibilities here, including Cystangium, Fevansia, Gautieria, Gymnomyces, Hymenogaster, Leucophleps, and Zelleromyces: all of which are loculate also. Additionally, Cystangium, Gymnomyces and Hymengaster are known to fruit year-round.

While this is a loculate fungus, I would hesitate to state it was Rhizopogon. Were that true, rhizomorphs should be present on every sporocarp present.
