M d  future  endings preceded by a  syllable -θη- make P  future  endings (only, when θη- is the initial  syllable, you  have a M fut of τίθημι; also there  exist a few stems in –θη-, that have Md  futures that  look like  P) 4)

1) These are valid for all forms:  *the endings for A subj 1^st, 2^nd and 3^rd sg may be extended to –ωμι, -ῃσθα, -ῃσιν in other dialects than Attic prose.
*Other subjunctives: in Epic -ωμεν, -ητε, -ωμαι, -ηται, -ώμεθα may be replaced by -ομεν,

     -ετε, -ομαι,  -εται, -όμεθα.

*The ending for Md/MdP 1^st pl is often –μεσθα in other dialects than Attic prose.

*The endings Md/MdP 3^rd pl may be replaced by –αται & -ατο in all optatives and
     some  other forms outside Attic prose.

*In Epic one often encounters A inf endings –(ε)μεν, -(ε)μεναι.

*The ending –(ό)ντων for the A imp 3^rd pl  is later often replaced by –(έ)τωσαν.

*The MdP participles are declined with 2^nd declension endings >M  & >Ne and with     
     1^st  declension endings (2^nd column) >F.

*The green-coloured endings are of course coupled to augment, but in Epic and Ionic non-     augmented forms are very frequent.

*The red-coloured endings are famous for having more than one possible determination. But as (for example) the A imp 3^rd pl is, to say the least, rare and the A ptc >M+Ne is very frequent, one need not be in dubio very much there. Same thing for A ao imp 2^nd sg and A fu ptc >N+Ac sg Ne, of which the first is the more frequent by far. Also, of course, one encounters far more A du ind 3^rd pl than A du ptc >M+Ne D pl. In the other cases there is no preponderance of one above the other.

Verbs that have no visible augment have a few more identical forms; in Epic, where the augment is optional, the same applies.

2) Notes only applicable to Aorist.

*The endings for A opt 2^nd sg, 3^rd sg and 3^rd pl are often –σαις, -σαι and –σαιεν
    instead   of –σειας, -σειεν and –σειαν.

*The ending –θησαν for P pa-ind 3^rd pl is in Epic often replaced by –θεν.

*The endings for P opt 1^st & 2^nd pl are often –θείημεν, -θείητε in later prose.

3) Notes applicable only to Perfect.

*The endings for A perf pa-ind in later prose may be –κειν, -κεις, -κει, -κειμεν,

   -κειτε, -κεισαν.

*The given forms are often replaced by periphrastic ones, i.e. ptc.+auxiliary verb εἰμί, e.g.       λελυκὼς ὦ, λελυκότες ὦσιν for λελύκω, λελύκωσιν; this occurs mainly in
     the subjunctive, optative and MdP ind 3^rd pl. The auxiliary is always εἰμί.

4) Notes applicable to P fu: a few stems that might cause trouble: Md fu of

αἰσθη-, (ἀπ)εχθη-, *μαθη-, φθη-; also Md fu of βοηθέω, ποθέω, *μυθέομαι, μοχθέω; and Md fu of καθίημι, μεθίημι, & fu of καθῆμαι; verbs marked with * have (many) composites.
