Well,you are giving so little information but in my experience it´s seems like Colletotrichum gloeosporioides s.l. But I´m not seen any setae in your pictures. Maybe if you can give more details ...

can you show us the symptoms caused by this fungus?

if it is anthracnose, it will be colethotrichum

Hi, since you said its an endophyte would I be correct in assuming that it did not cause pathology to the plant? I would be reluctant to try to classify based on morphology alone. Do you have the capability of getting some molecular characterization (e.g. ITS sequencing) done?

Looks like a Colletotrichum sp. but is important to have information of the type of the fruiting body produced(eg. acervuli, picnidia, etc.), the size of the conidia and conidiogenic cells, cultural characteristics and also is important the molecular characterization=sequence of ITS, actin, beta-tubulin, glyceraldehyde3-phosphate dehydrogenase and calmodulin genes .

Thank you sir...

Almost Colletotrichum sp.

Conidia looks like colletotrichum sp. (single celled oval shaped conidia)

I guess this might be colletotrichum species

It looks like Colletotrichium (conidia and fruiting body). Molecular identification is necessary.

The following article may be useful for identification

Damm, U., P. F. Cannon, J. H. C. Woudenberg, and P. W. Crous. "The Colletotrichum acutatum species complex." Studies in mycology 73 (2012): 37-113.

I agree with the identification to the Colletotrichum sp. level. It may well be of the gloeosporioides complex.

Thank you all....

This could be probably Pyrenochaeta but molecular confirmation is required to identify correctly

Following

Spores look like asci

I of course cannot be 100% certain, but I do work with fungi as a diagnostician.

The conidia of Image b do resemble those of several Colletotrichum species. Also, the yellow-orange waxy spore masses shown on Image a are oftentimes present with that genus. More could possibly be stated, if the measurements of the conidia were known.
