Question Hyphae, pseudohyphae, molds and yeast forms

Would someone please explain to me the meaning of hyphae, pseudohyphae, molds and yeast forms.
I have difficult understanding the explicit meaning of these.
Like they say Histoplama is a dimorphic fungus.

Default ill try my best

lets start from dimorphic - can have both configuration of mold as well as yeast
whats mold - multicellular fungal structure which forms hyphae (linear processes)
hyphae under LM can be septate-aspergillus (clear dividing lines are seen between cells in hyphae)
and nonseptate - mucor (no lines dividing cells in hyphae)

yeast is unicellular fungal organism
at body temperatures certain fungi have yeast form-blasto, histo, coccidio (forms endospores-unique), sporotrix wheres outside the body the are forming molds (at lower temperatures)
