I found this growing in the wet soil and have no idea what it is. Please advise.

Yes a Fungi … I think it might be Isaria farinosa… I’d also found this in Dalhousie… 🙂
Thank you very much … Feedback from another thread at Isaria cicadae submission :
“Isaria genus is still a less worked genus atleast in Indian Subcontinent with probably many species that are still undescribed, many species look much similar in morphology with only little differences, so one should be an expert who can examine the specimens microscopic details and can also do more phylogenetic analysis.
A reply from an entomopathogenic expert Nigel Hywel-Jones about my I. cicadae –
‘Ashutosh Sharma this is certainly an Isaria on a cicada nymph. I am working on this group in China but would hesitate to put a name to it for now. Several species have been described from around the World but none from the Indian sub-continent. With an old morphology based study of insect pathogenic isarioid fungi all those species off cicada nymphs were reduced to a single name – Isaria cicadae. As with many insect fungus groups molecular phylogenetics is demonstrating that what was once considered one species turns out to be several. This is beginning to prove the case also for cicada Isaria.’
About Isaria farinosa –
Isaria tenuipes complex differs from Isaria farinosa in having near pale yellow stroma while latter (I. farinosa) having much orange stroma.
So for now it will be better to make species page as Isaria cf. cicadae for this one.
While in the other two cases as host is not known so it can be either Isaria cf. cicadae if host was a cicada nymph or if some lepidoptera its likely something in Isaria tenuipes complex which comprises several undescribed species and is known from South East Asia.

Please… those are … photos… and yes … unless we have a sample at hand and have analysed properly it cannot be 100%…
