Please advice me about identity of this fungus produced spores on SDA media.

Shuvrah Rehman
Dear Shuvrah
It looks like a species of the genus Acremonium.

Hello Mehran Ghazavi your answer gave me idea of Acremonium.

Shuvrah
Dear Shuvrah
I agree with Mehran Ghazavi .. It may be a species of Acremonium.
with my best regards
Dear
You need reference to compare or molecular to identify species.
Thank

Hi Shuvrah
I agree with Mehran Ghazavi and Acremonium strictum
Sincerely
Acremonium. Study on agar media and identify the species. Send this to an expert who will tell you that it is old or a new one.
Hello Anisetti Thammayya thanks for answering and yes I will follow your advice

"Acremonium" is by no means a monophyletic genus - you might be better off to use DNA sequences than morphology for this group of fungi.
This isn't Acremonium. Clearly you have polyblastic conidiogeneous cells and also ramoconidia. Could you give more information (substrata, size of conidia, ...). Even so, molecular analysis is the best way to solve the issue.
Hi Alaa Jabbar Al-Mankhel please advice me any book name contain key of taxonomy.

Dear colleague,
The morphology definitely suggests a member of Acremonium, in its broad sense. However, there are many genera which look similar to Acremonium (see Seifert K, Morgan-Jones G, Gams W, Kendrick B. 2011. The genera of hyphomycetes. CBS Biodiversity Series 9), and the best way to determine genus and species identity is to obtain DNA sequences and compare them with those available at GenBank. It is advisable to start sequencing the ITS region to identify up to species or species complex level, and then to sequence protein-coding loci if necessary.
Some literature which might be helpful: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3065988/

Hi Shuvrah
I agree with Dr.Hugo, you can identify by DNA sequence ITS1 = forward, ITS4= reverse

Hi Shuvrah,
You can also see this book "Seifert K, Morgan-Jones G, Gams W, Kendrick B. 2011. The Genera of Hyphomycetes. CBS Biodiversity Series no. 9: 1–997. CBS-KNAW Fungal Biodiversity Centre, Utrecht, Netherlands ".
Hi Laith Al- Ani thanks again for your continuous support.

Hi Shuvrah
You are welcome, the determine of species by DNA sequence is confirms a species
hello Laith ok sure I am going to do sequencing because I have gotten primer
Dont worry I will send with gene bank accession number too.
Regards
Shuvrah
In my writings on Acremonium, I clearly warn everyone not to try to identify these species morphologically (except S. kiliense, A. camptosporum). It cannot be done at any scientific level of assurance. "Acremonium strictum" in particular is a notorious grab-bag that was used for dozens of species. Sequence, sequence, sequence. It does take some time, but you will find that the delay is well worthwhile. These photos don't look familiar to me; the one apparent instance of polyphialidic proliferation tends to suggest the Plectosphaerella clade. But anything is possible.
